host = "vendor1.platform.com"
|
||||
|
||||
Step 1: Custom domain? NO (ends with .platform.com)
|
||||
Step 2: Subdomain? YES

### Scenario 3: Development - localhost:8000/vendor/vendor1/
|
||||
```
|
||||
Customer → localhost:8000/vendor/vendor1/
|
||||
|
||||
FastAPI Middleware:
|
||||
host = "localhost:8000"
|
||||
path = "/vendor/vendor1/"
|
||||
|
||||
Step 1: Custom domain? NO (localhost)
|
||||
Step 2: Subdomain? NO (localhost has no subdomain)
|
||||
Step 3: Path-based? YES
|
||||
Extract "vendor1" from path
|

|

**At Domain Registrar (GoDaddy/Namecheap/etc):**
|
||||
```
|
||||

|

Type: A
|

Name: www
|
||||
Value: 123.45.67.89
|
||||
TTL: 3600
|
||||
|
||||
Type: TXT
|
||||
Name: _letzshop-verify
|
||||
Value: abc123xyz (verification token from your platform)
|
||||
TTL: 3600
|
||||
```
|
||||
|
||||
**After DNS propagates (5-15 mins):**
|
||||
1. Customer visits customdomain1.com
|
||||
2. DNS resolves to your server
|
||||
3. Nginx accepts request
|
||||
4. FastAPI middleware queries vendor_domains table
|
||||
5. Finds vendor_id = 1
|
||||
6. Shows Vendor 1's shop

# Custom Domain Implementation Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to implement custom domain support for your multi-tenant e-commerce platform, allowing vendors to use their own domains (e.g., `customdomain1.com`) instead of subdomains (`vendor1.platform.com`).
|
||||
|
||||
## Architecture Summary
|
||||
|
||||
### Current Routing (What You Have)
|
||||
```
|
||||
Development: localhost:8000/vendor/vendor1/ → Vendor 1
|
||||
Production: vendor1.platform.com → Vendor 1
|
||||
Admin: admin.platform.com → Admin Panel
|
||||
```
|
||||
|
||||
### New Routing (What You're Adding)
|
||||
```
|
||||
Custom Domain: customdomain1.com → Vendor 1
|
||||
Custom Domain: shop.mybrand.com → Vendor 2
|
||||
Subdomain: vendor1.platform.com → Vendor 1 (still works!)
|
||||
Path-based: localhost:8000/vendor/vendor1/ → Vendor 1 (still works!)
|
||||
```
|
||||
|
||||
## How It Works
|
||||
|
||||
### 1. Domain Mapping Flow
|
||||
|
||||
```
|
||||
Customer visits customdomain1.com
|
||||
↓
|
||||
DNS routes to your server
|
||||
↓
|
||||
Middleware reads Host header: "customdomain1.com"
|
||||
↓
|
||||
Queries vendor_domains table: WHERE domain = 'customdomain1.com'
|
||||
↓
|
||||
Finds VendorDomain record → vendor_id = 1
|
||||
↓
|
||||
Loads Vendor 1 data
|
||||
↓
|
||||
Sets request.state.vendor = Vendor 1
|
||||
↓
|
||||
All queries automatically scoped to Vendor 1
|
||||
↓
|
||||
Customer sees Vendor 1's shop
|
||||
```
|
||||
|
||||
### 2. Priority Order
|
||||
|
||||
The middleware checks in this order:
|
||||
|
||||
1. **Custom Domain** (highest priority)
|
||||
- Checks if host is NOT platform.com/localhost
|
||||
- Queries `vendor_domains` table
|
||||
|
||||
2. **Subdomain**
|
||||
- Checks if host matches `*.platform.com`
|
||||
- Queries `vendors.subdomain` field
|
||||
|
||||
3. **Path-based** (lowest priority - dev only)
|
||||
- Checks if path starts with `/vendor/`
|
||||
- Queries `vendors.subdomain` field
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### Step 1: Add Database Table
|
||||
|
||||
Create `vendor_domains` table to store custom domain mappings:
|
||||
|
||||
```sql
|
||||
CREATE TABLE vendor_domains (
|
||||
id SERIAL PRIMARY KEY,
|
||||
vendor_id INTEGER NOT NULL REFERENCES vendors(id) ON DELETE CASCADE,
|
||||
domain VARCHAR(255) NOT NULL UNIQUE,
|
||||
is_primary BOOLEAN DEFAULT FALSE,
|
||||
is_active BOOLEAN DEFAULT TRUE,
|
||||
is_verified BOOLEAN DEFAULT FALSE,
|
||||
verification_token VARCHAR(100) UNIQUE,
|
||||
verified_at TIMESTAMP WITH TIME ZONE,
|
||||
ssl_status VARCHAR(50) DEFAULT 'pending',
|
||||
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
|
||||
);
|
||||
|
||||
CREATE INDEX idx_domain_active ON vendor_domains(domain, is_active);
|
||||
```
|
||||
|
||||
**Files to create:**
|
||||
- `models/database/vendor_domain.py` - Model definition
|
||||
- `alembic/versions/XXX_add_vendor_domains.py` - Migration
|
||||
|
||||
### Step 2: Update Vendor Model
|
||||
|
||||
Add relationship to domains:
|
||||
|
||||
```python
|
||||
# models/database/vendor.py
|
||||
class Vendor(Base):
|
||||
# ... existing fields ...
|
||||
|
||||
domains = relationship(
|
||||
"VendorDomain",
|
||||
back_populates="vendor",
|
||||
cascade="all, delete-orphan"
|
||||
)
|
||||
```
|
||||
|
||||
### Step 3: Update Middleware
|
||||
|
||||
The middleware needs to check custom domains BEFORE subdomains.
|
||||
|
||||
**Key changes in `middleware/vendor_context.py`:**
|
||||
|
||||
```python
|
||||
def detect_vendor_context(request: Request):
|
||||
host = request.headers.get("host", "")
|
||||
|
||||
# NEW: Check if it's a custom domain
|
||||
if is_custom_domain(host):
|
||||
return {
|
||||
"domain": normalize_domain(host),
|
||||
"detection_method": "custom_domain"
|
||||
}
|
||||
|
||||
# EXISTING: Check subdomain
|
||||
if is_subdomain(host):
|
||||
return {
|
||||
"subdomain": extract_subdomain(host),
|
||||
"detection_method": "subdomain"
|
||||
}
|
||||
|
||||
# EXISTING: Check path
|
||||
if is_path_based(request.path):
|
||||
return {
|
||||
"subdomain": extract_from_path(request.path),
|
||||
"detection_method": "path"
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4: Create Admin Interface
|
||||
|
||||
Create API endpoints for managing domains:
|
||||
|
||||
```python
|
||||
POST /api/v1/admin/vendors/{vendor_id}/domains - Add domain
|
||||
GET /api/v1/admin/vendors/{vendor_id}/domains - List domains
|
||||
PUT /api/v1/admin/domains/{domain_id} - Update domain
|
||||
DELETE /api/v1/admin/domains/{domain_id} - Remove domain
|
||||
POST /api/v1/admin/domains/{domain_id}/verify - Verify ownership
|
||||
```
|
||||
|
||||
**Files to create:**
|
||||
- `app/api/v1/admin/vendor_domains.py` - API endpoints
|
||||
- `app/templates/admin/vendor_domains.html` - HTML interface
|
||||
|
||||
### Step 5: DNS Verification
|
||||
|
||||
To prevent domain hijacking, verify the vendor owns the domain:
|
||||
|
||||
**Verification Flow:**
|
||||
1. Vendor adds domain in admin panel
|
||||
2. System generates verification token: `abc123xyz`
|
||||
3. Vendor adds DNS TXT record:
|
||||
```
|
||||
Name: _letzshop-verify.customdomain1.com
|
||||
Type: TXT
|
||||
Value: abc123xyz
|
||||
```
|
||||
4. Admin clicks "Verify" button
|
||||
5. System queries DNS, checks for token
|
||||
6. If found, marks domain as verified
|
||||
|
||||
**Code:**
|
||||
```python
|
||||
@router.post("/domains/{domain_id}/verify")
|
||||
def verify_domain(domain_id: int, db: Session):
|
||||
domain = db.query(VendorDomain).get(domain_id)
|
||||
|
||||
# Query DNS for TXT record
|
||||
txt_records = dns.resolver.resolve(
|
||||
f"_letzshop-verify.{domain.domain}",
|
||||
'TXT'
|
||||
)
|
||||
|
||||
# Check if token matches
|
||||
for txt in txt_records:
|
||||
if txt.to_text() == domain.verification_token:
|
||||
domain.is_verified = True
|
||||
db.commit()
|
||||
return {"message": "Verified!"}
|
||||
|
||||
raise HTTPException(400, "Token not found")
|
||||
```
|
||||
|
||||
### Step 6: DNS Configuration
|
||||
|
||||
Vendor must configure their domain's DNS:
|
||||
|
||||
**Option A: Point to Platform (Simple)**
|
||||
```
|
||||
Type: A
|
||||
Name: @
|
||||
Value: 123.45.67.89 (your server IP)
|
||||
|
||||
Type: A
|
||||
Name: www
|
||||
Value: 123.45.67.89
|
||||
```
|
||||
|
||||
**Option B: CNAME to Platform (Better)**
|
||||
```
|
||||
Type: CNAME
|
||||
Name: @
|
||||
Value: platform.com
|
||||
|
||||
Type: CNAME
|
||||
Name: www
|
||||
Value: platform.com
|
||||
```
|
||||
|
||||
**Option C: Cloudflare Proxy (Best)**
|
||||
```
|
||||
Enable Cloudflare proxy → Automatic SSL + CDN
|
||||
```
|
||||
|
||||
### Step 7: SSL/TLS Certificates
|
||||
|
||||
For HTTPS on custom domains, you need SSL certificates.
|
||||
|
||||
**Option A: Wildcard Certificate (Simplest for subdomains)**
|
||||
```bash
|
||||
# Only works for *.platform.com
|
||||
certbot certonly --dns-cloudflare \
|
||||
-d "*.platform.com" \
|
||||
-d "platform.com"
|
||||
```
|
||||
|
||||
**Option B: Let's Encrypt with Certbot (Per-domain)**
|
||||
```bash
|
||||
# For each custom domain
|
||||
certbot certonly --webroot \
|
||||
-w /var/www/html \
|
||||
-d customdomain1.com \
|
||||
-d www.customdomain1.com
|
||||
```
|
||||
|
||||
**Option C: Cloudflare (Recommended)**
|
||||
- Vendor uses Cloudflare for their domain
|
||||
- Cloudflare provides SSL automatically
|
||||
- No server-side certificate management needed
|
||||
|
||||
**Option D: AWS Certificate Manager**
|
||||
- Use with AWS ALB/CloudFront
|
||||
- Automatic certificate provisioning
|
||||
- Free SSL certificates
|
||||
|
||||
### Step 8: Web Server Configuration
|
||||
|
||||
Configure Nginx/Apache to handle multiple domains:
|
||||
|
||||
**Nginx Configuration:**
|
||||
```nginx
|
||||
# /etc/nginx/sites-available/platform
|
||||
|
||||
server {
|
||||
listen 80;
|
||||
listen 443 ssl http2;
|
||||
|
||||
# Accept ANY domain
|
||||
server_name _;
|
||||
|
||||
# SSL configuration
|
||||
ssl_certificate /etc/letsencrypt/live/platform.com/fullchain.pem;
|
||||
ssl_certificate_key /etc/letsencrypt/live/platform.com/privkey.pem;
|
||||
|
||||
# Pass Host header to FastAPI
|
||||
location / {
|
||||
proxy_pass http://127.0.0.1:8000;
|
||||
proxy_set_header Host $host;
|
||||
proxy_set_header X-Real-IP $remote_addr;
|
||||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||||
proxy_set_header X-Forwarded-Proto $scheme;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Points:**
|
||||
- `server_name _;` accepts ALL domains
|
||||
- `proxy_set_header Host $host;` passes domain to FastAPI
|
||||
- FastAPI middleware reads the Host header to identify vendor
|
||||
|
||||
## Testing Guide
|
||||
|
||||
### Test 1: Subdomain (Existing)
|
||||
```bash
|
||||
# Development
|
||||
curl -H "Host: vendor1.localhost:8000" http://localhost:8000/
|
||||
|
||||
# Production
|
||||
curl https://vendor1.platform.com/
|
||||
```
|
||||
|
||||
### Test 2: Custom Domain (New)
|
||||
```bash
|
||||
# Add to /etc/hosts for testing:
|
||||
127.0.0.1 customdomain1.com
|
||||
|
||||
# Test locally
|
||||
curl -H "Host: customdomain1.com" http://localhost:8000/
|
||||
|
||||
# Production
|
||||
curl https://customdomain1.com/
|
||||
```
|
||||
|
||||
### Test 3: Path-based (Development)
|
||||
```bash
|
||||
curl http://localhost:8000/vendor/vendor1/
|
||||
```
|
||||
|
||||
## Data Flow Example
|
||||
|
||||
### Example: Customer visits customdomain1.com
|
||||
|
||||
**Step 1: DNS Resolution**
|
||||
```
|
||||
customdomain1.com → 123.45.67.89 (your server)
|
||||
```
|
||||
|
||||
**Step 2: HTTP Request**
|
||||
```
|
||||
GET / HTTP/1.1
|
||||
Host: customdomain1.com
|
||||
```
|
||||
|
||||
**Step 3: Nginx Proxy**
|
||||
```
|
||||
Nginx receives request
|
||||
↓
|
||||
Passes to FastAPI with Host header intact
|
||||
↓
|
||||
FastAPI receives: Host = "customdomain1.com"
|
||||
```
|
||||
|
||||
**Step 4: Middleware Processing**
|
||||
```python
|
||||
# vendor_context_middleware runs
|
||||
host = "customdomain1.com"
|
||||
|
||||
# Detect it's a custom domain
|
||||
is_custom = not host.endswith("platform.com") # True
|
||||
|
||||
# Query database
|
||||
vendor_domain = db.query(VendorDomain).filter(
|
||||
VendorDomain.domain == "customdomain1.com",
|
||||
VendorDomain.is_active == True,
|
||||
VendorDomain.is_verified == True
|
||||
).first()
|
||||
|
||||
# vendor_domain.vendor_id = 5
|
||||
# Load vendor
|
||||
vendor = db.query(Vendor).get(5)
|
||||
|
||||
# Set in request state
|
||||
request.state.vendor = vendor # Vendor 5
|
||||
```
|
||||
|
||||
**Step 5: Route Handler**
|
||||
```python
|
||||
@router.get("/")
|
||||
def shop_home(request: Request):
|
||||
vendor = request.state.vendor # Vendor 5
|
||||
|
||||
# All queries automatically filtered to Vendor 5
|
||||
products = db.query(Product).filter(
|
||||
Product.vendor_id == vendor.id
|
||||
).all()
|
||||
|
||||
return templates.TemplateResponse("shop/home.html", {
|
||||
"request": request,
|
||||
"vendor": vendor,
|
||||
"products": products
|
||||
})
|
||||
```
|
||||
|
||||
**Step 6: Response**
|
||||
```
|
||||
Customer sees Vendor 5's shop at customdomain1.com
|
||||
```
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### 1. Domain Verification
|
||||
- ALWAYS verify domain ownership via DNS TXT records
|
||||
- Never allow unverified domains to go live
|
||||
- Prevents domain hijacking
|
||||
|
||||
### 2. SSL/TLS
|
||||
- Require HTTPS for custom domains
|
||||
- Validate SSL certificates
|
||||
- Monitor certificate expiration
|
||||
|
||||
### 3. Vendor Isolation
|
||||
- Double-check vendor_id in all queries
|
||||
- Never trust user input for vendor selection
|
||||
- Always use `request.state.vendor`
|
||||
|
||||
### 4. Rate Limiting
|
||||
- Limit domain additions per vendor
|
||||
- Prevent DNS verification spam
|
||||
- Monitor failed verification attempts
|
||||
|
||||
### 5. Reserved Domains
|
||||
- Block platform.com and subdomains
|
||||
- Block reserved names (admin, api, www, mail)
|
||||
- Validate domain format
|
||||
|
||||
## Common Issues & Solutions
|
||||
|
||||
### Issue 1: "Domain not found"
|
||||
**Cause:** DNS not pointing to your server
|
||||
**Solution:** Check DNS A/CNAME records
|
||||
|
||||
### Issue 2: SSL certificate error
|
||||
**Cause:** No certificate for custom domain
|
||||
**Solution:** Use Cloudflare or provision certificate
|
||||
|
||||
### Issue 3: Vendor not detected
|
||||
**Cause:** Domain not in vendor_domains table
|
||||
**Solution:** Add domain via admin panel and verify
|
||||
|
||||
### Issue 4: Wrong vendor loaded
|
||||
**Cause:** Multiple vendors with same domain
|
||||
**Solution:** Enforce unique constraint on domain column
|
||||
|
||||
### Issue 5: Verification fails
|
||||
**Cause:** DNS TXT record not found
|
||||
**Solution:** Wait for DNS propagation (5-15 minutes)
|
||||
|
||||

|
||||
|
||||
## Summary
|
||||
|
||||
**What you're adding:**
|
||||
1. Database table to store domain → vendor mappings
|
||||
2. Middleware logic to detect custom domains

# Custom Domain Support - Executive Summary
|
||||
|
||||
## What You Asked For
|
||||
|
||||
> "I want to deploy multiple shops on multiple different domains like domain1.com/shop1, domain2.com/shop2"
|
||||
|
||||
## What You Currently Have
|
||||
|
||||
Your FastAPI multi-tenant e-commerce platform currently supports:
|
||||
|
||||
1. **Subdomain routing** (production): `vendor1.platform.com` → Vendor 1
|
||||
2. **Path-based routing** (development): `localhost:8000/vendor/vendor1/` → Vendor 1
|
||||
|
||||
## What's Missing
|
||||
|
||||
You **cannot** currently route custom domains like:
|
||||
- `customdomain1.com` → Vendor 1
|
||||
- `shop.mybrand.com` → Vendor 2
|
||||
|
||||
## The Solution
|
||||
|
||||
Add a **domain mapping table** that links custom domains to vendors:
|
||||
|
||||
```
|
||||
customdomain1.com → Vendor 1
|
||||
customdomain2.com → Vendor 2
|
||||
```
|
||||
|
||||
Your middleware checks this table BEFORE checking subdomains.
|
||||
|
||||
## High-Level Architecture
|
||||
|
||||
### Current Flow
|
||||
```
|
||||
Customer → vendor1.platform.com → Middleware checks subdomain → Finds Vendor 1
|
||||
```
|
||||
|
||||
### New Flow
|
||||
```
|
||||
Customer → customdomain1.com → Middleware checks domain mapping → Finds Vendor 1
|
||||
```
|
||||
|
||||
### Priority Order (after implementation)
|
||||
1. **Custom domain** (check `vendor_domains` table)
|
||||
2. **Subdomain** (check `vendors.subdomain` - still works!)
|
||||
3. **Path-based** (development mode - still works!)
|
||||
|
||||
## What Changes
|
||||
|
||||
### ✅ Changes Required
|
||||
|
||||
1. **Database**: Add `vendor_domains` table
|
||||
2. **Model**: Create `VendorDomain` model
|
||||
3. **Middleware**: Update to check custom domains first
|
||||
4. **Config**: Add `platform_domain` setting
|
||||
|
||||
### ❌ What Stays the Same
|
||||
|
||||
- Existing subdomain routing (still works!)
|
||||
- Path-based development routing (still works!)
|
||||
- Vendor isolation and security
|
||||
- All existing functionality
|
||||
- API endpoints
|
||||
- Admin panel
|
||||
|
||||
## Implementation Overview
|
||||
|
||||
### Database Schema
|
||||
```sql
|
||||
vendor_domains
|
||||
├── id (PK)
|
||||
├── vendor_id (FK → vendors.id)
|
||||
├── domain (UNIQUE) - e.g., "customdomain1.com"
|
||||
├── is_active
|
||||
├── is_verified (prevents domain hijacking)
|
||||
└── verification_token (for DNS verification)
|
||||
```
|
||||
|
||||
### Middleware Logic
|
||||
```python
|
||||
def detect_vendor(request):
|
||||
host = request.host
|
||||
|
||||
# NEW: Check if custom domain
|
||||
if not host.endswith("platform.com"):
|
||||
vendor = find_by_custom_domain(host)
|
||||
if vendor:
|
||||
return vendor
|
||||
|
||||
# EXISTING: Check subdomain
|
||||
if is_subdomain(host):
|
||||
vendor = find_by_subdomain(host)
|
||||
return vendor
|
||||
|
||||
# EXISTING: Check path
|
||||
if is_path_based(request.path):
|
||||
vendor = find_by_path(request.path)
|
||||
return vendor
|
||||
```
|
||||
|
||||
## Real-World Example
|
||||
|
||||
### Vendor Setup Process
|
||||
|
||||
**Step 1: Admin adds domain**
|
||||
- Admin logs in
|
||||
- Navigates to Vendor → Domains
|
||||
- Adds "customdomain1.com"
|
||||
- Gets verification token: `abc123xyz`
|
||||
|
||||
**Step 2: Vendor configures DNS**
|
||||
At their domain registrar (GoDaddy/Namecheap):
|
||||
```
|
||||
Type: A
|
||||
Name: @
|
||||
Value: 123.45.67.89 (your server IP)
|
||||
|
||||
Type: TXT
|
||||
Name: _letzshop-verify
|
||||
Value: abc123xyz
|
||||
```
|
||||
|
||||
**Step 3: Verification**
|
||||
- Wait 5-15 minutes for DNS propagation
|
||||
- Admin clicks "Verify Domain"
|
||||
- System checks DNS for TXT record
|
||||
- Domain marked as verified ✓
|
||||
|
||||
**Step 4: Go Live**
|
||||
- Customer visits `customdomain1.com`
|
||||
- Sees Vendor 1's shop
|
||||
- Everything just works!
|
||||
|
||||
## Technical Requirements
|
||||
|
||||
### Server Side
|
||||
- **Nginx**: Accept all domains (`server_name _;`)
|
||||
- **FastAPI**: Updated middleware
|
||||
- **Database**: New table for domain mappings
|
||||
|
||||
### DNS Side
|
||||
- Vendor points domain to your server
|
||||
- A record: `@` → Your server IP
|
||||
- Verification: TXT record for ownership proof
|
||||
|
||||
### SSL/TLS
|
||||
Three options:
|
||||
1. **Cloudflare** (easiest - automatic SSL)
|
||||
2. **Let's Encrypt** (per-domain certificates)
|
||||
3. **Wildcard** (subdomains only)
|
||||
|
||||
## Security
|
||||
|
||||
### Domain Verification
|
||||
✅ Prevents domain hijacking
|
||||
✅ Requires DNS TXT record
|
||||
✅ Token-based verification
|
||||
✅ Vendor must prove ownership
|
||||
|
||||
### Vendor Isolation
|
||||
✅ All queries filtered by vendor_id
|
||||
✅ No cross-vendor data leakage
|
||||
✅ Middleware sets request.state.vendor
|
||||
✅ Enforced at database level
|
||||
|
||||
## Benefits
|
||||
|
||||
### For Platform Owner (You)
|
||||
- ✅ More professional offering
|
||||
- ✅ Enterprise feature for premium vendors
|
||||
- ✅ Competitive advantage
|
||||
- ✅ Higher vendor retention
|
||||
- ✅ Still maintain single codebase
|
||||
|
||||
### For Vendors
|
||||
- ✅ Use their own brand domain
|
||||
- ✅ Better SEO (own domain)
|
||||
- ✅ Professional appearance
|
||||
- ✅ Customer trust
|
||||
- ✅ Marketing benefits
|
||||
|
||||
### For Customers
|
||||
- ✅ Seamless experience
|
||||
- ✅ Trust familiar domain
|
||||
- ✅ No platform branding visible
|
||||
- ✅ Better user experience
|
||||
|
||||
## Implementation Effort
|
||||
|
||||
### Minimal Changes
|
||||
- **New table**: 1 table (`vendor_domains`)
|
||||
- **New model**: 1 file (`vendor_domain.py`)
|
||||
- **Updated middleware**: Modify existing file
|
||||
- **Config**: Add 1 setting
|
||||
|
||||
### Time Estimate
|
||||
- **Core functionality**: 4-6 hours
|
||||
- **Testing**: 2-3 hours
|
||||
- **Production deployment**: 2-4 hours
|
||||
- **Total**: 1-2 days
|
||||
|
||||
### Risk Level
|
||||
- **Low risk**: New feature, doesn't break existing
|
||||
- **Backward compatible**: Old methods still work
|
||||
- **Rollback plan**: Simple database rollback
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Development Testing
|
||||
```bash
|
||||
# Add to /etc/hosts
|
||||
127.0.0.1 testdomain.local
|
||||
|
||||
# Add test data
|
||||
INSERT INTO vendor_domains (vendor_id, domain, is_verified)
|
||||
VALUES (1, 'testdomain.local', true);
|
||||
|
||||
# Test
|
||||
curl http://testdomain.local:8000/
|
||||
```
|
||||
|
||||
### Production Testing
|
||||
1. Add test domain for one vendor
|
||||
2. Configure DNS
|
||||
3. Verify detection works
|
||||
4. Monitor logs
|
||||
5. Roll out to more vendors

## Questions & Answers
|
||||
|
||||
**Q: Will this break existing functionality?**
|
||||
A: No! Subdomain and path-based routing still work. This adds a new layer on top.
|
||||
|
||||
**Q: What about SSL certificates?**
|
||||
A: Recommend Cloudflare (automatic) or Let's Encrypt (per-domain). See full guide.
|
||||
|
||||
**Q: How do vendors point their domain?**
|
||||
A: They add an A record pointing to your server IP. Simple DNS configuration.
|
||||
|
||||
**Q: What prevents domain hijacking?**
|
||||
A: DNS verification via TXT record. Vendor must prove ownership before domain goes live.
|
||||
|
||||
**Q: Can one vendor have multiple domains?**
|
||||
A: Yes! The `vendor_domains` table supports multiple domains per vendor.
|
||||
|
||||
**Q: What if vendor removes domain later?**
|
||||
A: Just mark as `is_active = false` in database. Easy to deactivate.
|
||||
|
||||
**Q: Do I need separate servers per domain?**
|
||||
A: No! Single server accepts all domains. Middleware routes to correct vendor.
|
||||
|
||||
## Conclusion
|
||||
|
||||
**Is your current architecture capable?**
|
||||
✅ Yes! Your multi-tenant architecture is perfect for this.
|
||||
|
||||
**What needs to change?**
|
||||
✅ Minimal changes: 1 table, 1 model, middleware update
|
||||
|
||||
**Is it worth it?**
|
||||
✅ Yes! Enterprise feature, competitive advantage, premium pricing
|
||||
|
||||
**Risk level?**
|
||||
✅ Low! Backward compatible, rollback-friendly
|
||||
|
||||
**Implementation complexity?**
|
||||
✅ Medium! 1-2 days for experienced FastAPI developer
|
||||
|
||||
**Recommendation:**
|
||||
✅ **GO FOR IT!** This is a valuable feature that fits naturally into your architecture.

# Custom Domain Implementation Checklist
|
||||
|
||||
## Phase 1: Database Setup
|
||||
|
||||
### Step 1.1: Create VendorDomain Model
|
||||
- [ ] Create file: `models/database/vendor_domain.py`
|
||||
- [ ] Copy model code from `vendor_domain_model.py`
|
||||
- [ ] Import in `models/database/__init__.py`
|
||||
|
||||
### Step 1.2: Update Vendor Model
|
||||
- [ ] Open `models/database/vendor.py`
|
||||
- [ ] Add `domains` relationship
|
||||
- [ ] Add `primary_domain` and `all_domains` properties
|
||||
|
||||
### Step 1.3: Create Migration
|
||||
- [ ] Generate migration: `alembic revision -m "add vendor domains"`
|
||||
- [ ] Copy upgrade/downgrade code from `migration_vendor_domains.py`
|
||||
- [ ] Apply migration: `alembic upgrade head`
|
||||
- [ ] Verify table exists: `psql -c "\d vendor_domains"`
|
||||
|
||||
## Phase 2: Configuration
|
||||
|
||||
### Step 2.1: Update Settings
|
||||
- [ ] Open `app/core/config.py`
|
||||
- [ ] Add `platform_domain = "platform.com"` (change to your actual domain)
|
||||
- [ ] Add custom domain settings from `config_updates.py`
|
||||
- [ ] Update `.env` file with new settings
|
||||
|
||||
### Step 2.2: Test Settings
|
||||
```bash
|
||||
# In Python shell
|
||||
from app.core.config import settings
|
||||
print(settings.platform_domain) # Should print your domain
|
||||
```
|
||||
|
||||
## Phase 3: Middleware Update
|
||||
|
||||
### Step 3.1: Backup Current Middleware
|
||||
```bash
|
||||
cp middleware/vendor_context.py middleware/vendor_context.py.backup
|
||||
```
|
||||
|
||||
### Step 3.2: Update Middleware
|
||||
- [ ] Open `middleware/vendor_context.py`
|
||||
- [ ] Replace with code from `updated_vendor_context.py`
|
||||
- [ ] Review the three detection methods (custom domain, subdomain, path)
|
||||
- [ ] Check imports are correct
|
||||
|
||||
### Step 3.3: Test Middleware Detection
|
||||
Create test file `tests/test_vendor_context.py`:
|
||||
```python
|
||||
def test_custom_domain_detection():
|
||||
# Mock request with custom domain
|
||||
request = MockRequest(host="customdomain1.com")
|
||||
context = VendorContextManager.detect_vendor_context(request)
|
||||
assert context["detection_method"] == "custom_domain"
|
||||
assert context["domain"] == "customdomain1.com"
|
||||
|
||||
def test_subdomain_detection():
|
||||
request = MockRequest(host="vendor1.platform.com")
|
||||
context = VendorContextManager.detect_vendor_context(request)
|
||||
assert context["detection_method"] == "subdomain"
|
||||
assert context["subdomain"] == "vendor1"
|
||||
|
||||
def test_path_detection():
|
||||
request = MockRequest(host="localhost", path="/vendor/vendor1/")
|
||||
context = VendorContextManager.detect_vendor_context(request)
|
||||
assert context["detection_method"] == "path"
|
||||
assert context["subdomain"] == "vendor1"
|
||||
```
|
||||
|
||||
Run tests:
|
||||
```bash
|
||||
pytest tests/test_vendor_context.py -v
|
||||
```
|
||||
|
||||
## Phase 4: Admin API Endpoints
|
||||
|
||||
### Step 4.1: Create Vendor Domains Router
|
||||
- [ ] Create file: `app/api/v1/admin/vendor_domains.py`
|
||||
- [ ] Copy code from `vendor_domains_api.py`
|
||||
- [ ] Verify imports work
|
||||
|
||||
### Step 4.2: Register Router
|
||||
Edit `app/api/v1/admin/__init__.py`:
|
||||
```python
|
||||
from .vendor_domains import router as vendor_domains_router
|
||||
|
||||
# In your admin router setup:
|
||||
admin_router.include_router(
|
||||
vendor_domains_router,
|
||||
prefix="/vendors",
|
||||
tags=["vendor-domains"]
|
||||
)
|
||||
```
|
||||
|
||||
### Step 4.3: Test API Endpoints
|
||||
```bash
|
||||
# Start server
|
||||
uvicorn main:app --reload
|
||||
|
||||
# Test endpoints (use Postman or curl)
|
||||
# 1. List vendor domains
|
||||
curl -H "Authorization: Bearer {admin_token}" \
|
||||
http://localhost:8000/api/v1/admin/vendors/1/domains
|
||||
|
||||
# 2. Add domain
|
||||
curl -X POST \
|
||||
-H "Authorization: Bearer {admin_token}" \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"vendor_id": 1, "domain": "test.com"}' \
|
||||
http://localhost:8000/api/v1/admin/vendors/1/domains
|
||||
```
|
||||
|
||||
## Phase 5: DNS Verification (Optional but Recommended)
|
||||
|
||||
### Step 5.1: Install DNS Library
|
||||
```bash
|
||||
pip install dnspython
|
||||
```
|
||||
|
||||
### Step 5.2: Test DNS Verification
|
||||
```python
|
||||
# In Python shell
|
||||
import dns.resolver
|
||||
|
||||
# Test querying TXT record
|
||||
answers = dns.resolver.resolve("_letzshop-verify.example.com", "TXT")
|
||||
for txt in answers:
|
||||
print(txt.to_text())
|
||||
```
|
||||
|
||||
## Phase 6: Local Testing
|
||||
|
||||
### Step 6.1: Test with /etc/hosts
|
||||
Edit `/etc/hosts`:
|
||||
```
|
||||
127.0.0.1 testdomain1.local
|
||||
127.0.0.1 testdomain2.local
|
||||
```
|
||||
|
||||
### Step 6.2: Add Test Data
|
||||
```sql
|
||||
-- Add test vendor
|
||||
INSERT INTO vendors (subdomain, name, is_active)
|
||||
VALUES ('testvendor', 'Test Vendor', true);
|
||||
|
||||
-- Add test domain
|
||||
INSERT INTO vendor_domains (vendor_id, domain, is_verified, is_active)
|
||||
VALUES (1, 'testdomain1.local', true, true);
|
||||
```
|
||||
|
||||
### Step 6.3: Test in Browser
|
||||
```bash
|
||||
# Start server
|
||||
uvicorn main:app --reload
|
||||
|
||||
# Visit in browser:
|
||||
# http://testdomain1.local:8000/
|
||||
|
||||
# Check logs for:
|
||||
# "✓ Vendor found via custom domain: testdomain1.local → Test Vendor"
|
||||
```
|
||||
|
||||
## Phase 7: Web Server Configuration
|
||||
|
||||
### Step 7.1: Update Nginx Configuration
|
||||
Edit `/etc/nginx/sites-available/your-site`:
|
||||
```nginx
|
||||
server {
|
||||
listen 80;
|
||||
listen 443 ssl http2;
|
||||
|
||||
# Accept ALL domains
|
||||
server_name _;
|
||||
|
||||
# SSL configuration (update paths)
|
||||
ssl_certificate /path/to/cert.pem;
|
||||
ssl_certificate_key /path/to/key.pem;
|
||||
|
||||
location / {
|
||||
proxy_pass http://127.0.0.1:8000;
|
||||
proxy_set_header Host $host; # CRITICAL: Pass domain to FastAPI
|
||||
proxy_set_header X-Real-IP $remote_addr;
|
||||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||||
proxy_set_header X-Forwarded-Proto $scheme;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 7.2: Test Nginx Config
|
||||
```bash
|
||||
sudo nginx -t
|
||||
sudo systemctl reload nginx
|
||||
```
|
||||
|

|
||||
curl https://platform.com/health
|
||||
|
||||
# Check logs
|
||||
tail -f /var/log/your-app/app.log
|
||||
|
||||
# Look for:
|
||||
# "✓ Vendor found via custom domain: ..."
|
||||
```
|
||||
|
||||
## Phase 9: Vendor Setup Process
|
||||
|
||||
### Step 9.1: Admin Adds Domain for Vendor
|
||||
1. Log into admin panel
|
||||
2. Go to Vendors → Select Vendor → Domains
|
||||
3. Click "Add Domain"
|
||||
4. Enter domain: `customdomain1.com`
|
||||
5. Click Save
|
||||
6. Copy verification instructions
|
||||
|
||||
### Step 9.2: Vendor Configures DNS
|
||||
Vendor goes to their domain registrar and adds:
|
||||
|
||||
**A Record:**
|
||||
```
|
||||
Type: A
|
||||
Name: @
|
||||
Value: [your server IP]
|
||||
TTL: 3600
|
||||
```
|
||||
|
||||
**Verification TXT Record:**
|
||||
```
|
||||
Type: TXT
|
||||
Name: _letzshop-verify
|
||||
Value: [token from step 9.1]
|
||||
TTL: 3600
|
||||
```
|
||||
|
||||
### Step 9.3: Admin Verifies Domain
|
||||
1. Wait 5-15 minutes for DNS propagation
|
||||
2. In admin panel → Click "Verify Domain"
|
||||
3. System checks DNS for TXT record
|
||||
4. If found → Domain marked as verified
|
||||
5. Domain is now active!
|
||||
|
||||
### Step 9.4: Test Custom Domain
|
||||
```bash
|
||||
# Visit vendor's custom domain
|
||||
curl https://customdomain1.com/
|
||||
|
||||
# Should show vendor's shop
|
||||
# Check server logs for confirmation
|
||||
```
|
||||
|
||||
## Phase 10: SSL/TLS Setup
|
||||
|
||||
### Option A: Let's Encrypt (Per-Domain)
|
||||
```bash
|
||||
# For each custom domain
|
||||
sudo certbot certonly --webroot \
|
||||
-w /var/www/html \
|
||||
-d customdomain1.com \
|
||||
-d www.customdomain1.com
|
||||
|
||||
# Auto-renewal
|
||||
sudo certbot renew --dry-run
|
||||
```
|
||||
|
||||
### Option B: Cloudflare (Recommended)
|
||||
1. Vendor adds domain to Cloudflare
|
||||
2. Cloudflare provides SSL automatically
|
||||
3. Points Cloudflare DNS to your server
|
||||
4. No server-side certificate needed
|
||||
|
||||
### Option C: Wildcard (Subdomains Only)
|
||||
```bash
|
||||
# Only for *.platform.com
|
||||
sudo certbot certonly --dns-cloudflare \
|
||||
-d "*.platform.com" \
|
||||
-d "platform.com"
|
||||
```
|
||||
|
||||
## Troubleshooting Guide
|
||||
|
||||
### Issue: Vendor not detected
|
||||
**Check:**
|
||||
```sql
|
||||
-- Is domain in database?
|
||||
SELECT * FROM vendor_domains WHERE domain = 'customdomain1.com';
|
||||
|
||||
-- Is domain verified?
|
||||
SELECT * FROM vendor_domains
|
||||
WHERE domain = 'customdomain1.com'
|
||||
AND is_verified = true
|
||||
AND is_active = true;
|
||||
|
||||
-- Is vendor active?
|
||||
SELECT v.* FROM vendors v
|
||||
JOIN vendor_domains vd ON v.id = vd.vendor_id
|
||||
WHERE vd.domain = 'customdomain1.com';
|
||||
```
|
||||
|
||||
**Check logs:**
|
||||
```bash
|
||||
# Look for middleware debug logs
|
||||
grep "Vendor context" /var/log/your-app/app.log
|
||||
|
||||
# Should see:
|
||||
# "🏪 Vendor context: Shop Name (subdomain) via custom_domain"
|
||||
```
|
||||
|
||||
### Issue: Wrong vendor loaded
|
||||
**Check for duplicates:**
|
||||
```sql
|
||||
-- Should be no duplicates
|
||||
SELECT domain, COUNT(*)
|
||||
FROM vendor_domains
|
||||
GROUP BY domain
|
||||
HAVING COUNT(*) > 1;
|
||||
```
|
||||
|
||||
### Issue: DNS verification fails
|
||||
**Check DNS propagation:**
|
||||
```bash
|
||||
# Check if TXT record exists
|
||||
dig _letzshop-verify.customdomain1.com TXT
|
||||
|
||||
# Should show verification token
|
||||
```
|
||||
|
||||
### Issue: SSL certificate error
|
||||
**Options:**
|
||||
1. Use Cloudflare (easiest)
|
||||
2. Get Let's Encrypt certificate for domain
|
||||
3. Tell vendor to use their own SSL proxy
|
||||
|
||||
## Monitoring & Maintenance
|
||||
|
||||
### Add Logging
|
||||
```python
|
||||
# In middleware
|
||||
logger.info(
|
||||
f"Request received for {host}",
|
||||
extra={
|
||||
"host": host,
|
||||
"vendor_id": vendor.id if vendor else None,
|
||||
"detection_method": context.get("detection_method")
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### Monitor Metrics
|
||||
- [ ] Number of active custom domains
|
||||
- [ ] Failed domain verifications
|
||||
- [ ] Traffic per domain
|
||||
- [ ] SSL certificate expirations
|
||||
|
||||
### Regular Maintenance

||||
- [ ] Review unverified domains (> 7 days old)
|
||||
- [ ] Check SSL certificate status
|
||||
- [ ] Monitor DNS changes
|
||||
- [ ] Clean up inactive domains
|
||||
|
||||
## Success Criteria
|
||||
|
||||
- [ ] Existing subdomain routing still works
|
||||
- [ ] New custom domains can be added via admin
|
||||
- [ ] DNS verification works
|
||||
- [ ] Multiple domains can point to same vendor
|
||||
- [ ] Middleware correctly identifies vendor
|
||||
- [ ] All vendor queries properly scoped
|
||||
- [ ] No security vulnerabilities (domain hijacking prevented)
|
||||
- [ ] Monitoring in place
|
||||
- [ ] Documentation updated
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If something goes wrong:
|
||||
|
||||
1. **Database:**
|
||||
```bash
|
||||
alembic downgrade -1 # Rollback migration
|
||||
```
|
||||
|
||||
2. **Code:**
|
||||
```bash
|
||||
git checkout HEAD~1 # Revert to previous commit
|
||||
sudo systemctl restart your-app
|
||||
```
|
||||
|
||||
3. **Middleware:**
|
||||
```bash
|
||||
cp middleware/vendor_context.py.backup middleware/vendor_context.py
|
||||
sudo systemctl restart your-app
|
||||
```
|
||||
|
||||
4. **Nginx:**
|
||||
```bash
|
||||
# Restore previous nginx config from backup
|
||||
sudo cp /etc/nginx/sites-available/your-site.backup /etc/nginx/sites-available/your-site
|
||||
sudo systemctl reload nginx
|
||||
```
|
||||
|
||||

## 📝 Key Concepts
|
||||
|
||||
### Multi-Tenant Architecture
|
||||
Your app already supports this! Each vendor is a tenant with isolated data.
|
||||
|
||||
### Domain Mapping
|
||||
New concept: Links custom domains to vendors via database table.
|
||||
|
||||
### Request Flow Priority
|
||||
1. Custom domain (NEW)
|
||||
2. Subdomain (EXISTING)
|
||||
3. Path-based (EXISTING)
|
||||
|
||||
### DNS Verification
|
||||
Security feature: Proves vendor owns the domain before activation.
|
||||
|
||||
### Vendor Isolation
|
||||
Already working! Custom domains just add another entry point.

# Quick Start: Custom Domains in 30 Minutes
|
||||
|
||||
This guide gets you from zero to working custom domains in 30 minutes.
|
||||
|
||||
## What You're Building
|
||||
|
||||
**Before:**
|
||||
- Vendors only accessible via `vendor1.platform.com`
|
||||
|
||||
**After:**
|
||||
- Vendors accessible via custom domains: `customdomain1.com` → Vendor 1
|
||||
- Old subdomain method still works!
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- FastAPI application with vendor context middleware (you have this ✓)
|
||||
- PostgreSQL database (you have this ✓)
|
||||
- Admin privileges to add database tables
|
||||
|
||||
## 5-Step Setup
|
||||
|
||||
### Step 1: Add Database Table (5 minutes)
|
||||
|
||||
Create and run this migration:
|
||||
|
||||
```sql
|
||||
-- Create vendor_domains table
|
||||
CREATE TABLE vendor_domains (
|
||||
id SERIAL PRIMARY KEY,
|
||||
vendor_id INTEGER NOT NULL REFERENCES vendors(id) ON DELETE CASCADE,
|
||||
domain VARCHAR(255) NOT NULL UNIQUE,
|
||||
is_primary BOOLEAN DEFAULT FALSE,
|
||||
is_active BOOLEAN DEFAULT TRUE,
|
||||
is_verified BOOLEAN DEFAULT FALSE,
|
||||
verification_token VARCHAR(100) UNIQUE,
|
||||
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
|
||||
);
|
||||
|
||||
CREATE INDEX idx_domain_active ON vendor_domains(domain, is_active);
|
||||
```
|
||||
|
||||
**Verify:**
|
||||
```bash
|
||||
psql your_database -c "\d vendor_domains"
|
||||
```
|
||||
|
||||
### Step 2: Create Model (5 minutes)
|
||||
|
||||
Create `models/database/vendor_domain.py`:
|
||||
|
||||
```python
|
||||
from sqlalchemy import Column, Integer, String, Boolean, DateTime, ForeignKey
|
||||
from sqlalchemy.orm import relationship
|
||||
from app.core.database import Base
|
||||
from datetime import datetime, timezone
|
||||
|
||||
class VendorDomain(Base):
|
||||
__tablename__ = "vendor_domains"
|
||||
|
||||
id = Column(Integer, primary_key=True)
|
||||
vendor_id = Column(Integer, ForeignKey("vendors.id", ondelete="CASCADE"))
|
||||
domain = Column(String(255), nullable=False, unique=True)
|
||||
is_primary = Column(Boolean, default=False)
|
||||
is_active = Column(Boolean, default=True)
|
||||
is_verified = Column(Boolean, default=False)
|
||||
verification_token = Column(String(100))
|
||||
created_at = Column(DateTime(timezone=True), default=lambda: datetime.now(timezone.utc))
|
||||
|
||||
vendor = relationship("Vendor", back_populates="domains")
|
||||
|
||||
@classmethod
|
||||
def normalize_domain(cls, domain: str) -> str:
|
||||
return domain.replace("https://", "").replace("http://", "").rstrip("/").lower()
|
||||
```
|
||||
|
||||
Update `models/database/vendor.py`:
|
||||
```python
|
||||
# Add to Vendor class
|
||||
domains = relationship("VendorDomain", back_populates="vendor")
|
||||
```
|
||||
|
||||
### Step 3: Update Middleware (10 minutes)
|
||||
|
||||
Replace your `middleware/vendor_context.py` with this key section:
|
||||
|
||||
```python
|
||||
from models.database.vendor_domain import VendorDomain
|
||||
|
||||
class VendorContextManager:
|
||||
@staticmethod
|
||||
def detect_vendor_context(request: Request) -> Optional[dict]:
|
||||
host = request.headers.get("host", "").split(":")[0]
|
||||
path = request.url.path
|
||||
|
||||
# NEW: Priority 1 - Custom domain check
|
||||
from app.core.config import settings
|
||||
platform_domain = getattr(settings, 'platform_domain', 'platform.com')
|
||||
|
||||
is_custom_domain = (
|
||||
host and
|
||||
not host.endswith(f".{platform_domain}") and
|
||||
host != platform_domain and
|
||||
"localhost" not in host and
|
||||
not host.startswith("admin.")
|
||||
)
|
||||
|
||||
if is_custom_domain:
|
||||
return {
|
||||
"domain": VendorDomain.normalize_domain(host),
|
||||
"detection_method": "custom_domain",
|
||||
"host": host
|
||||
}
|
||||
|
||||
# EXISTING: Priority 2 - Subdomain check
|
||||
if "." in host and not "localhost" in host:
|
||||
parts = host.split(".")
|
||||
if len(parts) >= 2 and parts[0] not in ["www", "admin", "api"]:
|
||||
return {
|
||||
"subdomain": parts[0],
|
||||
"detection_method": "subdomain",
|
||||
"host": host
|
||||
}
|
||||
|
||||
# EXISTING: Priority 3 - Path-based check
|
||||
if path.startswith("/vendor/"):
|
||||
path_parts = path.split("/")
|
||||
if len(path_parts) >= 3:
|
||||
return {
|
||||
"subdomain": path_parts[2],
|
||||
"detection_method": "path",
|
||||
"path_prefix": f"/vendor/{path_parts[2]}"
|
||||
}
|
||||
|
||||
return None
|
||||
|
||||
@staticmethod
|
||||
def get_vendor_from_context(db: Session, context: dict) -> Optional[Vendor]:
|
||||
if not context:
|
||||
return None
|
||||
|
||||
# NEW: Custom domain lookup
|
||||
if context.get("detection_method") == "custom_domain":
|
||||
vendor_domain = (
|
||||
db.query(VendorDomain)
|
||||
.filter(VendorDomain.domain == context["domain"])
|
||||
.filter(VendorDomain.is_active == True)
|
||||
.filter(VendorDomain.is_verified == True)
|
||||
.first()
|
||||
)
|
||||
if vendor_domain and vendor_domain.vendor.is_active:
|
||||
return vendor_domain.vendor
|
||||
|
||||
# EXISTING: Subdomain/path lookup
|
||||
if "subdomain" in context:
|
||||
return (
|
||||
db.query(Vendor)
|
||||
.filter(func.lower(Vendor.subdomain) == context["subdomain"].lower())
|
||||
.filter(Vendor.is_active == True)
|
||||
.first()
|
||||
)
|
||||
|
||||
return None
|
||||
```
|
||||
|
||||
### Step 4: Add Config (2 minutes)
|
||||
|
||||
Edit `app/core/config.py`:
|
||||
|
||||
```python
|
||||
class Settings(BaseSettings):
|
||||
# ... existing settings ...
|
||||
|
||||
# Add this
|
||||
platform_domain: str = "platform.com" # Change to YOUR domain
|
||||
```
|
||||
|
||||
Update `.env`:
|
||||
```
|
||||
PLATFORM_DOMAIN=platform.com # Change to YOUR domain
|
||||
```
|
||||
|
||||
### Step 5: Test Locally (8 minutes)
|
||||
|
||||
**Add test data:**
|
||||
```sql
|
||||
-- Assuming you have a vendor with id=1
|
||||
INSERT INTO vendor_domains (vendor_id, domain, is_active, is_verified)
|
||||
VALUES (1, 'testdomain.local', true, true);
|
||||
```
|
||||
|
||||
**Edit /etc/hosts:**
|
||||
```bash
|
||||
sudo nano /etc/hosts
|
||||
# Add:
|
||||
127.0.0.1 testdomain.local
|
||||
```
|
||||
|
||||
**Start server:**
|
||||
```bash
|
||||
uvicorn main:app --reload
|
||||
```
|
||||
|
||||
**Test in browser:**
|
||||
```
|
||||
http://testdomain.local:8000/
|
||||
```
|
||||
|
||||
**Check logs for:**
|
||||
```
|
||||
✓ Vendor found via custom domain: testdomain.local → [Vendor Name]
|
||||
```
|
||||
|
||||
## Done! 🎉
|
||||
|
||||
You now have custom domain support!
|
||||
|
||||
## Quick Test Checklist
|
||||
|
||||
- [ ] Can access vendor via custom domain: `testdomain.local:8000`
|
||||
- [ ] Can still access via subdomain: `vendor1.localhost:8000`
|
||||
- [ ] Can still access via path: `localhost:8000/vendor/vendor1/`
|
||||
- [ ] Logs show correct detection method
|
||||
- [ ] Database has vendor_domains table
|
||||
- [ ] Model imports work
|
||||
|
||||
## What Works Now
|
||||
|
||||
✅ **Custom domains** → Checks vendor_domains table
|
||||
✅ **Subdomains** → Checks vendors.subdomain (existing)
|
||||
✅ **Path-based** → Development mode (existing)
|
||||
✅ **Admin** → Still accessible
|
||||
✅ **Vendor isolation** → Each vendor sees only their data
|
||||
|
||||
## Next Steps
|
||||
|
||||
### For Development:
|
||||
1. Test with multiple custom domains
|
||||
2. Add more test vendors
|
||||
3. Verify queries are scoped correctly
|
||||
|
||||
### For Production:
|
||||
1. Add admin API endpoints (see full guide)
|
||||
2. Add DNS verification (see full guide)
|
||||
3. Configure Nginx to accept all domains
|
||||
4. Set up SSL strategy
|
||||
|
||||
## Common Issues & Fixes
|
||||
|
||||
**Issue:** "Vendor not found"
|
||||
```sql
|
||||
-- Check if domain exists and is verified
|
||||
SELECT * FROM vendor_domains WHERE domain = 'testdomain.local';
|
||||
|
||||
-- Should show is_verified = true and is_active = true
|
||||
```
|
||||
|
||||
**Issue:** Wrong vendor loaded
|
||||
```sql
|
||||
-- Check for duplicate domains
|
||||
SELECT domain, COUNT(*) FROM vendor_domains GROUP BY domain HAVING COUNT(*) > 1;
|
||||
```
|
||||
|
||||
**Issue:** Still using subdomain detection
|
||||
```python
|
||||
# Check middleware logs - should show:
|
||||
# detection_method: "custom_domain"
|
||||
# Not "subdomain"
|
||||
```
|
||||
|
||||
## Production Checklist
|
||||
|
||||
Before going live:
|
||||
|
||||
- [ ] Update `PLATFORM_DOMAIN` in production .env
|
||||
- [ ] Configure Nginx: `server_name _;`
|
||||
- [ ] Set up SSL strategy (Cloudflare recommended)
|
||||
- [ ] Add proper DNS verification (security!)
|
||||
- [ ] Add admin UI for domain management
|
||||
- [ ] Test with real custom domain
|
||||
- [ ] Monitor logs for errors
|
||||
- [ ] Set up rollback plan
|
||||
|
||||

# Custom Domain Support - Complete Implementation Package
|
||||
|
||||
## 🎯 Your Question Answered
|
||||
|
||||
**Q: "Can my FastAPI multi-tenant app support multiple shops on different custom domains like customdomain1.com and customdomain2.com?"**
|
||||
|
||||
**A: YES! ✅** Your architecture is **perfectly suited** for this. You just need to add a domain mapping layer.
|
||||
|
||||

|
||||
|
||||
## 📊 What You Have vs What You Need
|
||||
|
||||
### ✅ What You Already Have (Perfect!)
|
||||
- Multi-tenant architecture with vendor isolation
|
||||
- Vendor context middleware
|
||||
- Subdomain routing: `vendor1.platform.com`
|
||||

### ➕ What You Need to Add (Simple!)
|
||||
- Database table: `vendor_domains` (1 table)
|
||||
- Enhanced middleware: Check custom domains first
|
||||
- DNS verification: Prevent domain hijacking
|
||||
|
||||
---
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
```bash
|
||||
# 1. Add database table (5 minutes)
|
||||
CREATE TABLE vendor_domains (
|
||||
id SERIAL PRIMARY KEY,
|
||||
vendor_id INTEGER REFERENCES vendors(id),
|
||||
domain VARCHAR(255) UNIQUE,
|
||||
is_verified BOOLEAN DEFAULT FALSE
|
||||
);
|
||||
|
||||
# 2. Update middleware (10 minutes)
|
||||
# See: updated_vendor_context.py
|
||||
|
||||
# 3. Test locally (5 minutes)
|
||||
# Add to /etc/hosts:
|
||||
127.0.0.1 testdomain.local
|
||||
|
||||
# Add test data:
|
||||
INSERT INTO vendor_domains (vendor_id, domain, is_verified)
|
||||
VALUES (1, 'testdomain.local', true);
|
||||
|
||||
# Visit: http://testdomain.local:8000/
|
||||
# ✅ Should show Vendor 1's shop!
|
||||
```
|
||||
|
||||
**Total time: 30 minutes** ⏱️

|
||||
|
||||
## 🏗️ Architecture Overview
|
||||
|
||||
### Before (Current)
|
||||
```
|
||||
Customer → vendor1.platform.com → Middleware checks subdomain → Vendor 1
|
||||
```
|
||||
|
||||
### After (With Custom Domains)
|
||||
```
|
||||
Customer → customdomain1.com → Middleware checks domain table → Vendor 1
|
||||
(subdomain still works too!)
|
||||
```
|
||||
|
||||
### How It Works
|
||||
```
|
||||
1. Request arrives: Host = "customdomain1.com"
|
||||
2. Middleware: Is it custom domain? YES
|
||||
3. Query: SELECT vendor_id FROM vendor_domains WHERE domain = 'customdomain1.com'
|
||||
4. Result: vendor_id = 1
|
||||
5. Load: Vendor 1 data
|
||||
6. Render: Vendor 1's shop
|
||||
```

## 🔐 Security Features
|
||||
|
||||
- ✅ **DNS Verification**: Vendors must prove domain ownership
|
||||
- ✅ **TXT Record Check**: Token-based verification
|
||||
- ✅ **Vendor Isolation**: Each vendor sees only their data
|
||||
- ✅ **Active Status**: Domains can be deactivated
|
||||
- ✅ **Audit Trail**: Track domain changes
|
||||
|
||||
---
|
||||
|
||||
## 🌐 DNS Configuration (Vendor Side)
|
||||
|
||||
When a vendor wants to use `customdomain1.com`:
|
||||
|
||||
```
|
||||
# At their domain registrar:
|
||||
|
||||
1. A Record:
|
||||
Name: @
|
||||
Value: 123.45.67.89 (your server IP)
|
||||
|
||||
2. Verification TXT Record:
|
||||
Name: _letzshop-verify
|
||||
Value: [token from your platform]
|
||||
|
||||
3. Wait 5-15 minutes for DNS propagation
|
||||
|
||||
4. Admin verifies domain
|
||||
|
||||
5. Domain goes live! 🎉
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🚀 Deployment Options
|
||||
|
||||
### Development
|
||||
```bash
|
||||
# Test locally with /etc/hosts
|
||||
127.0.0.1 testdomain.local
|
||||
```
|
||||
|
||||
### Staging
|
||||
```bash
|
||||
# Use subdomain for testing
|
||||
staging-vendor.platform.com
|
||||
```
|
||||
|
||||
### Production
|
||||
```bash
|
||||
# Full custom domain support
|
||||
customdomain1.com → Vendor 1
|
||||
customdomain2.com → Vendor 2
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 💡 Why This Works
|
||||
|
||||
Your architecture is **already multi-tenant**:
|
||||
- ✅ Vendor isolation exists
|
||||
- ✅ Middleware detects context
|
||||
- ✅ All queries scoped to vendor
|
||||
- ✅ Request state management works
|
||||
|
||||
You just need to add **one more detection method**:
|
||||
1. ~~Check subdomain~~ (existing)
|
||||
2. ~~Check path~~ (existing)
|
||||
3. **Check custom domain** (new!)

# Multi-Theme Shop System - Complete Implementation Guide
|
||||
|
||||
## 🎨 Overview
|
||||
|
||||
This guide explains how to implement vendor-specific themes in your FastAPI multi-tenant e-commerce platform, allowing each vendor to have their own unique shop design, colors, branding, and layout.
|
||||
|
||||
## What You're Building
|
||||
|
||||
**Before:**
|
||||
- All vendor shops look the same
|
||||
- Same colors, fonts, layouts
|
||||
- Only vendor name changes
|
||||
|
||||
**After:**
|
||||
- Each vendor has unique theme
|
||||
- Custom colors, fonts, logos
|
||||
- Different layouts per vendor
|
||||
- Vendor-specific branding
|
||||
- CSS customization support
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
```
|
||||
Request → Vendor Middleware → Theme Middleware → Template Rendering
|
||||
↓ ↓ ↓
|
||||
Sets vendor Loads theme Applies styles
|
||||
in request config for and branding
|
||||
state vendor
|
||||
```
|
||||
|
||||
### Data Flow
|
||||
|
||||
```
|
||||
1. Customer visits: customdomain1.com
|
||||
2. Vendor middleware: Identifies Vendor 1
|
||||
3. Theme middleware: Loads Vendor 1's theme
|
||||
4. Template receives:
|
||||
- vendor: Vendor 1 object
|
||||
- theme: Vendor 1 theme config
|
||||
5. Template renders with:
|
||||
- Vendor 1 colors
|
||||
- Vendor 1 logo
|
||||
- Vendor 1 layout preferences
|
||||
- Vendor 1 custom CSS
|
||||
```
|
||||
|
||||
## Implementation Steps
|
||||
|
||||
### Step 1: Add Theme Database Table
|
||||
|
||||
Create the `vendor_themes` table:
|
||||
|
||||
```sql
|
||||
CREATE TABLE vendor_themes (
|
||||
id SERIAL PRIMARY KEY,
|
||||
vendor_id INTEGER UNIQUE NOT NULL REFERENCES vendors(id) ON DELETE CASCADE,
|
||||
theme_name VARCHAR(100) DEFAULT 'default',
|
||||
is_active BOOLEAN DEFAULT TRUE,
|
||||
|
||||
-- Colors (JSON)
|
||||
colors JSONB DEFAULT '{
|
||||
"primary": "#6366f1",
|
||||
"secondary": "#8b5cf6",
|
||||
"accent": "#ec4899",
|
||||
"background": "#ffffff",
|
||||
"text": "#1f2937",
|
||||
"border": "#e5e7eb"
|
||||
}'::jsonb,
|
||||
|
||||
-- Typography
|
||||
font_family_heading VARCHAR(100) DEFAULT 'Inter, sans-serif',
|
||||
font_family_body VARCHAR(100) DEFAULT 'Inter, sans-serif',
|
||||
|
||||
-- Branding
|
||||
logo_url VARCHAR(500),
|
||||
logo_dark_url VARCHAR(500),
|
||||
favicon_url VARCHAR(500),
|
||||
banner_url VARCHAR(500),
|
||||
|
||||
-- Layout
|
||||
layout_style VARCHAR(50) DEFAULT 'grid',
|
||||
header_style VARCHAR(50) DEFAULT 'fixed',
|
||||
product_card_style VARCHAR(50) DEFAULT 'modern',
|
||||
|
||||
-- Customization
|
||||
custom_css TEXT,
|
||||
social_links JSONB DEFAULT '{}'::jsonb,
|
||||
|
||||
-- Meta
|
||||
meta_title_template VARCHAR(200),
|
||||
meta_description TEXT,
|
||||
|
||||
-- Timestamps
|
||||
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
|
||||
updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
|
||||
);
|
||||
|
||||
CREATE INDEX idx_vendor_themes_vendor_id ON vendor_themes(vendor_id);
|
||||
CREATE INDEX idx_vendor_themes_active ON vendor_themes(vendor_id, is_active);
|
||||
```
|
||||
|
||||
### Step 2: Create VendorTheme Model
|
||||
|
||||
File: `models/database/vendor_theme.py`
|
||||
|
||||
See the complete model in `/home/claude/vendor_theme_model.py`
|
||||
|
||||
**Key features:**
|
||||
- JSON fields for flexible color schemes
|
||||
- Brand asset URLs (logo, favicon, banner)
|
||||
- Layout preferences
|
||||
- Custom CSS support
|
||||
- CSS variables generator
|
||||
- to_dict() for template rendering
|
||||
|
||||
### Step 3: Update Vendor Model
|
||||
|
||||
Add theme relationship to `models/database/vendor.py`:
|
||||
|
||||
```python
|
||||
from sqlalchemy.orm import relationship
|
||||
|
||||
class Vendor(Base):
|
||||
# ... existing fields ...
|
||||
|
||||
# Add theme relationship
|
||||
theme = relationship(
|
||||
"VendorTheme",
|
||||
back_populates="vendor",
|
||||
uselist=False, # One-to-one relationship
|
||||
cascade="all, delete-orphan"
|
||||
)
|
||||
|
||||
@property
|
||||
def active_theme(self):
|
||||
"""Get vendor's active theme or return None"""
|
||||
if self.theme and self.theme.is_active:
|
||||
return self.theme
|
||||
return None
|
||||
```
|
||||
|
||||
### Step 4: Create Theme Context Middleware
|
||||
|
||||
File: `middleware/theme_context.py`
|
||||
|
||||
See complete middleware in `/home/claude/theme_context_middleware.py`
|
||||
|
||||
**What it does:**
|
||||
1. Runs AFTER vendor_context_middleware
|
||||
2. Loads theme for detected vendor
|
||||
3. Injects theme into request.state
|
||||
4. Falls back to default theme if needed
|
||||
|
||||
**Add to main.py:**
|
||||
```python
|
||||
from middleware.theme_context import theme_context_middleware
|
||||
|
||||
# AFTER vendor_context_middleware
|
||||
app.middleware("http")(theme_context_middleware)
|
||||
```
|
||||
|
||||
### Step 5: Create Shop Base Template
|
||||
|
||||
File: `app/templates/shop/base.html`
|
||||
|
||||
See complete template in `/home/claude/shop_base_template.html`
|
||||
|
||||
**Key features:**
|
||||
- Injects CSS variables from theme
|
||||
- Vendor-specific logo (light/dark mode)
|
||||
- Theme-aware header/footer
|
||||
- Social links from theme config
|
||||
- Custom CSS injection
|
||||
- Dynamic favicon
|
||||
- SEO meta tags
|
||||
|
||||
**Template receives:**
|
||||
```python
|
||||
{
|
||||
"vendor": vendor_object, # From vendor middleware
|
||||
"theme": theme_dict, # From theme middleware
|
||||
}
|
||||
```
|
||||
|
||||
### Step 6: Create Shop Layout JavaScript
|
||||
|
||||
File: `static/shop/js/shop-layout.js`
|
||||
|
||||
See complete code in `/home/claude/shop_layout.js`
|
||||
|
||||
**Provides:**
|
||||
- Theme toggling (light/dark)
|
||||
- Cart management
|
||||
- Mobile menu
|
||||
- Search overlay
|
||||
- Toast notifications
|
||||
- Price formatting
|
||||
- Date formatting
|
||||
|
||||
### Step 7: Update Route Handlers
|
||||
|
||||
Ensure theme is passed to templates:
|
||||
|
||||
```python
|
||||
from middleware.theme_context import get_current_theme
|
||||
|
||||
@router.get("/")
|
||||
async def shop_home(request: Request, db: Session = Depends(get_db)):
|
||||
vendor = request.state.vendor
|
||||
theme = get_current_theme(request) # or request.state.theme
|
||||
|
||||
# Get products for vendor
|
||||
products = db.query(Product).filter(
|
||||
Product.vendor_id == vendor.id,
|
||||
Product.is_active == True
|
||||
).all()
|
||||
|
||||
return templates.TemplateResponse("shop/home.html", {
|
||||
"request": request,
|
||||
"vendor": vendor,
|
||||
"theme": theme,
|
||||
"products": products
|
||||
})
|
||||
```
|
||||
|
||||
**Note:** If middleware is set up correctly, theme is already in `request.state.theme`, so you may not need to explicitly pass it!
|
||||
|
||||
## How Themes Work
|
||||
|
||||
### CSS Variables System
|
||||
|
||||
Each theme generates CSS custom properties:
|
||||
|
||||
```css
|
||||
:root {
|
||||
--color-primary: #6366f1;
|
||||
--color-secondary: #8b5cf6;
|
||||
--color-accent: #ec4899;
|
||||
--color-background: #ffffff;
|
||||
--color-text: #1f2937;
|
||||
--color-border: #e5e7eb;
|
||||
--font-heading: Inter, sans-serif;
|
||||
--font-body: Inter, sans-serif;
|
||||
}
|
||||
```
|
||||
|
||||
**Usage in HTML/CSS:**
|
||||
```html
|
||||
<!-- In templates -->
|
||||
<button style="background-color: var(--color-primary)">
|
||||
Click Me
|
||||
</button>
|
||||
|
||||
<h1 style="font-family: var(--font-heading)">
|
||||
Welcome
|
||||
</h1>
|
||||
```
|
||||
|
||||
```css
|
||||
/* In stylesheets */
|
||||
.btn-primary {
|
||||
background-color: var(--color-primary);
|
||||
color: var(--color-background);
|
||||
}
|
||||
|
||||
.heading {
|
||||
font-family: var(--font-heading);
|
||||
color: var(--color-text);
|
||||
}
|
||||
```
|
||||
|
||||
### Theme Configuration Example
|
||||
|
||||
```python
|
||||
# Example theme for "Modern Electronics Store"
|
||||
theme = {
|
||||
"theme_name": "tech-modern",
|
||||
"colors": {
|
||||
"primary": "#2563eb", # Blue
|
||||
"secondary": "#0ea5e9", # Sky Blue
|
||||
"accent": "#f59e0b", # Amber
|
||||
"background": "#ffffff",
|
||||
"text": "#111827",
|
||||
"border": "#e5e7eb"
|
||||
},
|
||||
"fonts": {
|
||||
"heading": "Roboto, sans-serif",
|
||||
"body": "Open Sans, sans-serif"
|
||||
},
|
||||
"branding": {
|
||||
"logo": "/media/vendors/tech-store/logo.png",
|
||||
"logo_dark": "/media/vendors/tech-store/logo-dark.png",
|
||||
"favicon": "/media/vendors/tech-store/favicon.ico",
|
||||
"banner": "/media/vendors/tech-store/banner.jpg"
|
||||
},
|
||||
"layout": {
|
||||
"style": "grid",
|
||||
"header": "fixed",
|
||||
"product_card": "modern"
|
||||
},
|
||||
"social_links": {
|
||||
"facebook": "https://facebook.com/techstore",
|
||||
"instagram": "https://instagram.com/techstore",
|
||||
"twitter": "https://twitter.com/techstore"
|
||||
},
|
||||
"custom_css": """
|
||||
.product-card {
|
||||
border-radius: 12px;
|
||||
box-shadow: 0 4px 6px rgba(0, 0, 0, 0.1);
|
||||
}
|
||||
|
||||
.product-card:hover {
|
||||
transform: translateY(-4px);
|
||||
box-shadow: 0 8px 12px rgba(0, 0, 0, 0.15);
|
||||
}
|
||||
"""
|
||||
}
|
||||
```
|
||||
|
||||
## Creating Theme Presets
|
||||
|
||||
You can create predefined theme templates:
|
||||
|
||||
```python
|
||||
# app/core/theme_presets.py
|
||||
|
||||
THEME_PRESETS = {
|
||||
"modern": {
|
||||
"colors": {
|
||||
"primary": "#6366f1",
|
||||
"secondary": "#8b5cf6",
|
||||
"accent": "#ec4899",
|
||||
},
|
||||
"fonts": {
|
||||
"heading": "Inter, sans-serif",

## Admin Interface for Theme Management
|

```
|
||||
|
||||

|
||||
theme_id = Column(Integer, ForeignKey("vendor_themes.id"))
|
||||
conversion_rate = Column(Numeric(5, 2))
|
||||
avg_session_duration = Column(Integer)
|
||||
bounce_rate = Column(Numeric(5, 2))
|
||||
```
|
||||

# Theme System Integration Guide for Your Existing Architecture
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
This guide shows how to integrate the multi-theme system into your **existing** FastAPI + Alpine.js + Tailwind CSS architecture.
|
||||
|
||||
**Key Point:** You already have 80% of what you need! Your `theme_config` JSON field in the Vendor model is the foundation.
|
||||
|
||||
## ✅ What You Already Have
|
||||
|
||||
1. **Vendor model** with `theme_config` JSON field ✅
|
||||
2. **Alpine.js** frontend pattern established ✅
|
||||
3. **Tailwind CSS** for styling ✅
|
||||
4. **Admin pages** with Jinja2 templates ✅
|
||||
5. **Vendor context middleware** ✅
|
||||
|
||||
## 🚀 Integration Steps
|
||||
|
||||
### Step 1: Update Vendor Model (5 minutes)
|
||||
|
||||
Your current model already has `theme_config`, so just add helper methods:
|
||||
|
||||
```python
|
||||
# models/database/vendor.py
|
||||
|
||||
class Vendor(Base, TimestampMixin):
|
||||
# ... existing fields ...
|
||||
theme_config = Column(JSON, default=dict) # ✅ You already have this!
|
||||
|
||||
# ADD THIS PROPERTY:
|
||||
@property
|
||||
def theme(self):
|
||||
"""
|
||||
Get theme configuration for this vendor.
|
||||
Returns dict with theme configuration.
|
||||
"""
|
||||
if self.theme_config:
|
||||
return self._normalize_theme_config(self.theme_config)
|
||||
return self._get_default_theme()
|
||||
|
||||
def _normalize_theme_config(self, config: dict) -> dict:
|
||||
"""Ensure theme_config has all required fields"""
|
||||
return {
|
||||
"colors": config.get("colors", {
|
||||
"primary": "#6366f1",
|
||||
"secondary": "#8b5cf6",
|
||||
"accent": "#ec4899"
|
||||
}),
|
||||
"fonts": config.get("fonts", {
|
||||
"heading": "Inter, sans-serif",
|
||||
"body": "Inter, sans-serif"
|
||||
}),
|
||||
"layout": config.get("layout", {
|
||||
"style": "grid",
|
||||
"header": "fixed"
|
||||
}),
|
||||
"branding": config.get("branding", {
|
||||
"logo": None,
|
||||
"favicon": None
|
||||
}),
|
||||
"custom_css": config.get("custom_css", None),
|
||||
"css_variables": self._generate_css_variables(config)
|
||||
}
|
||||
|
||||
def _generate_css_variables(self, config: dict) -> dict:
|
||||
"""Generate CSS custom properties from theme"""
|
||||
colors = config.get("colors", {})
|
||||
fonts = config.get("fonts", {})
|
||||
|
||||
return {
|
||||
"--color-primary": colors.get("primary", "#6366f1"),
|
||||
"--color-secondary": colors.get("secondary", "#8b5cf6"),
|
||||
"--color-accent": colors.get("accent", "#ec4899"),
|
||||
"--font-heading": fonts.get("heading", "Inter, sans-serif"),
|
||||
"--font-body": fonts.get("body", "Inter, sans-serif"),
|
||||
}
|
||||
|
||||
def _get_default_theme(self) -> dict:
|
||||
"""Default theme if none configured"""
|
||||
return {
|
||||
"colors": {"primary": "#6366f1", "secondary": "#8b5cf6", "accent": "#ec4899"},
|
||||
"fonts": {"heading": "Inter, sans-serif", "body": "Inter, sans-serif"},
|
||||
"layout": {"style": "grid", "header": "fixed"},
|
||||
"branding": {"logo": None, "favicon": None},
|
||||
"custom_css": None,
|
||||
"css_variables": {
|
||||
"--color-primary": "#6366f1",
|
||||
"--color-secondary": "#8b5cf6",
|
||||
"--color-accent": "#ec4899",
|
||||
"--font-heading": "Inter, sans-serif",
|
||||
"--font-body": "Inter, sans-serif",
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**That's it for the model!** No new tables needed if you use the existing `theme_config` JSON field.
|
||||
|
||||
### Step 2: Add Theme Route to Admin Pages (2 minutes)
|
||||
|
||||
Add to `app/api/v1/admin/pages.py`:
|
||||
|
||||
```python
|
||||
@router.get("/vendors/{vendor_code}/theme", response_class=HTMLResponse, include_in_schema=False)
|
||||
async def admin_vendor_theme_page(
|
||||
request: Request,
|
||||
vendor_code: str = Path(..., description="Vendor code"),
|
||||
current_user: User = Depends(get_current_admin_user),
|
||||
db: Session = Depends(get_db)
|
||||
):
|
||||
"""
|
||||
Render vendor theme customization page.
|
||||
"""
|
||||
return templates.TemplateResponse(
|
||||
"admin/vendor-theme.html",
|
||||
{
|
||||
"request": request,
|
||||
"user": current_user,
|
||||
"vendor_code": vendor_code,
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### Step 3: Create Theme Management Page (5 minutes)
|
||||
|
||||
1. Copy the HTML template from `/mnt/user-data/outputs/vendor-theme-page.html`
|
||||
2. Save as `app/templates/admin/vendor-theme.html`
|
||||
3. Copy the JS component from `/mnt/user-data/outputs/vendor-theme.js`
|
||||
4. Save as `static/admin/js/vendor-theme.js`
|
||||
|
||||
### Step 4: Update Vendor Detail Page to Link to Theme (2 minutes)
|
||||
|
||||
In your `app/templates/admin/vendor-detail.html`, add a "Customize Theme" button:
|
||||
|
||||
```html
|
||||
<!-- In your vendor details page -->
|
||||
<div class="flex space-x-2">
|
||||
<a :href="`/admin/vendors/${vendor?.vendor_code}/edit`"
|
||||
class="px-4 py-2 text-sm font-medium text-white bg-purple-600 rounded-lg hover:bg-purple-700">
|
||||
Edit Vendor
|
||||
</a>
|
||||
|
||||
<!-- ADD THIS BUTTON -->
|
||||
<a :href="`/admin/vendors/${vendor?.vendor_code}/theme`"
|
||||
class="px-4 py-2 text-sm font-medium text-purple-700 bg-white border border-purple-600 rounded-lg hover:bg-purple-50">
|
||||
Customize Theme
|
||||
</a>
|
||||
</div>
|
||||
```
|
||||
|
||||
### Step 5: Update Shop Template to Use Theme (10 minutes)
|
||||
|
||||
Create `app/templates/shop/base.html` (if you don't have it yet):
|
||||
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html lang="en" x-data="shopLayoutData()" x-bind:class="{ 'dark': dark }">
|
||||
<head>
|
||||
<meta charset="UTF-8">
|
||||
<meta name="viewport" content="width=device-width, initial-scale=1.0">
|
||||
<title>{% block title %}{{ vendor.name }}{% endblock %}</title>
|
||||
|
||||
<!-- ✅ CRITICAL: Inject theme CSS variables -->
|
||||
<style id="vendor-theme-variables">
|
||||
:root {
|
||||
{% for key, value in theme.css_variables.items() %}
|
||||
{{ key }}: {{ value }};
|
||||
{% endfor %}
|
||||
}
|
||||
|
||||
/* Custom CSS from vendor */
|
||||
{% if theme.custom_css %}
|
||||
{{ theme.custom_css | safe }}
|
||||
{% endif %}
|

|

|
||||
|
||||
### Step 6: Update Shop Routes to Pass Theme (5 minutes)
|
||||
|
||||
In your shop route handlers (e.g., `app/api/v1/public/vendors/pages.py`):
|
||||
|
||||
```python
|
||||
@router.get("/")
|
||||
async def shop_home(request: Request, db: Session = Depends(get_db)):
|
||||
vendor = request.state.vendor # From vendor context middleware
|
||||
|
||||
# Get theme from vendor
|
||||
theme = vendor.theme # Uses the property we added
|
||||
|
||||
return templates.TemplateResponse("shop/home.html", {
|
||||
"request": request,
|
||||
"vendor": vendor,
|
||||
"theme": theme, # ✅ Pass theme to template
|
||||
})
|
||||
```
|
||||
|
||||
## 📊 Using Tailwind with Theme Variables
|
||||
|
||||
The magic is in CSS variables! Tailwind can use your theme colors:
|
||||
|
||||
```html
|
||||
<!-- In your shop templates -->
|
||||
|
||||
<!-- Primary color button -->
|
||||
<button class="px-4 py-2 rounded-lg"
|
||||
style="background-color: var(--color-primary); color: white;">
|
||||
Shop Now
|
||||
</button>
|
||||
|
||||
<!-- Or use Tailwind utilities with inline styles -->
|
||||
<div class="text-2xl font-bold"
|
||||
style="color: var(--color-primary); font-family: var(--font-heading)">
|
||||
Welcome to {{ vendor.name }}
|
||||
</div>
|
||||
|
||||
<!-- Product card with theme colors -->
|
||||
<div class="p-4 bg-white rounded-lg border"
|
||||
style="border-color: var(--color-primary)">
|
||||
<h3 class="text-lg font-semibold"
|
||||
style="color: var(--color-primary)">
|
||||
Product Name
|
||||
</h3>
|
||||
</div>
|
||||
```
|
||||
|
||||
## 🎨 How It All Works Together
|
||||
|
||||
### 1. Admin Customizes Theme
|
||||
|
||||
```
|
||||
Admin → /admin/vendors/TECHSTORE/theme
|
||||
↓
|
||||
Sees theme editor (colors, fonts, layout)
|
||||
↓
|
||||
Clicks "Save Theme"
|
||||
↓
|
||||
PUT /api/v1/admin/vendors/TECHSTORE
|
||||
↓
|
||||
Updates vendor.theme_config JSON:
|
||||
{
|
||||
"colors": {
|
||||
"primary": "#2563eb", // Blue
|
||||
"secondary": "#0ea5e9"
|
||||
},
|
||||
"fonts": {
|
||||
"heading": "Roboto, sans-serif"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Customer Visits Shop
|
||||
|
||||
```
|
||||
Customer → techstore.platform.com
|
||||
↓
|
||||
Vendor middleware identifies Vendor = TECHSTORE
|
||||
↓
|
||||
Shop route loads:
|
||||
- vendor object
|
||||
- theme = vendor.theme (property we added)
|
||||
↓
|
||||
Template renders with:
|
||||
:root {
|
||||
--color-primary: #2563eb;
|
||||
--color-secondary: #0ea5e9;
|
||||
--font-heading: Roboto, sans-serif;
|
||||
}
|
||||
↓
|
||||
Customer sees blue-themed shop with Roboto headings!
|
||||
```
|
||||
|
||||
## 🔧 API Endpoints Needed
|
||||
|
||||
Your existing vendor update endpoint already works! Just update `theme_config`:
|
||||
|
||||
```python
|
||||
# app/api/v1/admin/vendors.py
|
||||
|
||||
@router.put("/vendors/{vendor_code}")
|
||||
async def update_vendor(
|
||||
vendor_code: str,
|
||||
vendor_data: VendorUpdate,
|
||||
db: Session = Depends(get_db),
|
||||
current_user: User = Depends(get_current_admin_user)
|
||||
):
|
||||
vendor = db.query(Vendor).filter(
|
||||
Vendor.vendor_code == vendor_code
|
||||
).first()
|
||||
|
||||
if not vendor:
|
||||
raise HTTPException(404, "Vendor not found")
|
||||
|
||||
# Update fields
|
||||
if vendor_data.theme_config is not None:
|
||||
vendor.theme_config = vendor_data.theme_config # ✅ This already works!
|
||||
|
||||
# ... other updates ...
|
||||
|
||||
db.commit()
|
||||
db.refresh(vendor)
|
||||
|
||||
return vendor
|
||||
```
|
||||
|
||||
**That's it!** Your existing update endpoint handles theme updates.
|
||||
|
||||
## 🎯 Quick Test
|
||||
|
||||
### 1. Test Theme Editor
|
||||
|
||||
```bash
|
||||
# Start your app
|
||||
uvicorn main:app --reload
|
||||
|
||||
# Visit admin
|
||||
http://localhost:8000/admin/vendors/YOUR_VENDOR_CODE/theme
|
||||
|
||||
# Change colors and save
|
||||
# Check database:
|
||||
SELECT theme_config FROM vendors WHERE vendor_code = 'YOUR_VENDOR_CODE';
|
||||
|
||||
# Should see:
|
||||
# {"colors": {"primary": "#your-color", ...}}
|
||||
```
|
||||
|
||||
### 2. Test Shop Rendering
|
||||
|
||||
```bash
|
||||
# Visit vendor shop
|
||||
http://vendor1.localhost:8000/
|
||||
|
||||
# Inspect page source
|
||||
# Should see:
|
||||
# <style id="vendor-theme-variables">
|
||||
# :root {
|
||||
# --color-primary: #your-color;
|
||||
# }
|
||||
# </style>
|
||||
```
|
||||
|
||||
## 📦 Files to Create/Update
|
||||
|
||||
### Create New Files:
|
||||
1. `app/templates/admin/vendor-theme.html` ← From `/mnt/user-data/outputs/vendor-theme-page.html`
|
||||
2. `static/admin/js/vendor-theme.js` ← From `/mnt/user-data/outputs/vendor-theme.js`
|
||||
3. `app/templates/shop/base.html` ← Base shop template with theme support
|
||||
|
||||
### Update Existing Files:
|
||||
1. `models/database/vendor.py` ← Add `theme` property and helper methods
|
||||
2. `app/api/v1/admin/pages.py` ← Add theme route
|
||||
3. `models/schema/vendor.py` ← Already has `theme_config` in VendorUpdate ✅
|
||||
|
||||
## 🎨 Example: Different Themes
|
||||
|
||||
### Vendor 1: Tech Store (Blue Theme)
|
||||
```python
|
||||
{
|
||||
"colors": {
|
||||
"primary": "#2563eb",
|
||||
"secondary": "#0ea5e9",
|
||||
"accent": "#f59e0b"
|
||||
},
|
||||
"fonts": {
|
||||
"heading": "Roboto, sans-serif",
|
||||
"body": "Open Sans, sans-serif"
|
||||
},
|
||||
"layout": {
|
||||
"style": "grid"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Vendor 2: Fashion Boutique (Pink Theme)
|
||||
```python
|
||||
{
|
||||
"colors": {
|
||||
"primary": "#ec4899",
|
||||
"secondary": "#f472b6",
|
||||
"accent": "#fbbf24"
|
||||
},
|
||||
"fonts": {
|
||||
"heading": "Playfair Display, serif",
|
||||
"body": "Lato, sans-serif"
|
||||
},
|
||||
"layout": {
|
||||
"style": "masonry"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## ✅ Checklist
|
||||
|
||||
- [ ] Add `theme` property to Vendor model
|
||||
- [ ] Add theme route to `pages.py`
|
||||
- [ ] Create `vendor-theme.html` template
|
||||
- [ ] Create `vendor-theme.js` Alpine component
|
||||
- [ ] Create shop `base.html` with theme injection
|
||||
- [ ] Update shop routes to pass `theme`
|
||||
- [ ] Add "Customize Theme" button to vendor detail page
|
||||

|
||||
|
||||
## 🚀 Benefits
|
||||
|
||||
### For You:
|
||||
- ✅ Uses existing `theme_config` field (no migration!)
|
||||
- ✅ Works with current Alpine.js pattern
|
||||
- ✅ Compatible with Tailwind CSS
|
||||
- ✅ Follows your established conventions
|
||||
|
||||
### For Vendors:
|
||||
- ✅ Easy theme customization
|
||||
- ✅ Live preview
|
||||
- ✅ Preset templates
|
||||
- ✅ Custom branding
|
||||
|
||||
## 💡 Advanced: Tailwind Custom Configuration
|
||||
|
||||
If you want Tailwind to use theme variables natively:
|
||||
|
||||
```javascript
|
||||
// tailwind.config.js
|
||||
module.exports = {
|
||||
theme: {
|
||||
extend: {
|
||||
colors: {
|
||||
primary: 'var(--color-primary)',
|
||||
secondary: 'var(--color-secondary)',
|
||||
accent: 'var(--color-accent)',
|
||||
},
|
||||
fontFamily: {
|
||||
heading: 'var(--font-heading)',
|
||||
body: 'var(--font-body)',
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then you can use:
|
||||
```html
|
||||
<button class="bg-primary text-white">Shop Now</button>
|
||||
<h1 class="font-heading text-primary">Welcome</h1>
|
||||
```
|
||||
|
||||
## 🎉 Summary
|
||||
|
||||
**Your architecture is perfect for this!**
|
||||
|
||||
1. You already have `theme_config` JSON field ✅
|
||||
2. Just add a `theme` property to access it ✅
|
||||
3. Create admin page to edit it ✅
|
||||
4. Inject CSS variables in shop templates ✅
|
||||
5. Use variables with Tailwind/inline styles ✅
|
||||
|
||||
**Total implementation time: ~30 minutes**
|
||||
|
||||
Each vendor gets unique theming without any database migrations! 🚀

# Vendor Domains - Refactored Architecture Implementation Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This document explains the refactored vendor domains implementation that follows your application's architecture patterns with proper separation of concerns.
|
||||
|
||||
## Architecture Summary
|
||||
|
||||
The implementation follows these key principles:
|
||||
|
||||
1. **Separation of Concerns**: Endpoints, service layer, schemas, and database models are separated
|
||||
2. **Exception-Based Error Handling**: Custom exceptions with proper HTTP status codes
|
||||
3. **Service Layer Pattern**: Business logic isolated in service classes
|
||||
4. **Pydantic Validation**: Input validation using Pydantic schemas
|
||||
5. **Consistent Response Format**: Standardized response models
|
||||
|
||||

├── vendor.py # Updated Vendor model
|
||||
└── vendor_domain.py # VendorDomain model
|
||||
```
|
||||
|
||||
## Components
|
||||
|
||||
### 1. Exceptions (`app/exceptions/vendor_domain.py`)
|
||||
|
||||
Custom exceptions for domain operations:
|
||||
|
||||
```python
|
||||
# Resource Not Found (404)
|
||||
- VendorDomainNotFoundException
|
||||
|
||||
# Conflicts (409)
|
||||
- VendorDomainAlreadyExistsException
|
||||
|
||||
# Validation (422)
|
||||
- InvalidDomainFormatException
|
||||
- ReservedDomainException
|
||||
|
||||
# Business Logic (400)
|
||||
- DomainNotVerifiedException
|
||||
- DomainVerificationFailedException
|
||||
- DomainAlreadyVerifiedException
|
||||
- MultiplePrimaryDomainsException
|
||||
- MaxDomainsReachedException
|
||||
- UnauthorizedDomainAccessException
|
||||
|
||||
# External Service (502)
|
||||
- DNSVerificationException
|
||||
```
|
||||
|
||||
**Key Features:**
|
||||
- Inherit from appropriate base exceptions
|
||||
- Include relevant context in `details` dict
|
||||
- Proper HTTP status codes
|
||||
- Clear, actionable error messages
|
||||
|
||||
### 2. Pydantic Schemas (`models/schema/vendor_domain.py`)
|
||||
|
||||
Input validation and response models:
|
||||
|
||||
```python
|
||||
# Request Schemas
|
||||
- VendorDomainCreate # For adding domains
|
||||
- VendorDomainUpdate # For updating settings
|
||||
|
||||
# Response Schemas
|
||||
- VendorDomainResponse # Single domain
|
||||
- VendorDomainListResponse # List of domains
|
||||
- DomainVerificationInstructions # DNS instructions
|
||||
- DomainVerificationResponse # Verification result
|
||||
- DomainDeletionResponse # Deletion confirmation
|
||||
```
|
||||
|
||||
**Validation Features:**
|
||||
- Domain normalization (lowercase, remove protocol)
|
||||
- Reserved subdomain checking
|
||||
- Format validation using regex
|
||||
- Field validators with custom error messages
|
||||
|
||||
### 3. Service Layer (`app/services/vendor_domain_service.py`)
|
||||
|
||||
Business logic and database operations:
|
||||
|
||||
```python
|
||||
class VendorDomainService:
|
||||
# Core Operations
|
||||
add_domain() # Add custom domain
|
||||
get_vendor_domains() # List vendor's domains
|
||||
get_domain_by_id() # Get single domain
|
||||
update_domain() # Update settings
|
||||
delete_domain() # Remove domain
|
||||
|
||||
# Verification
|
||||
verify_domain() # DNS verification
|
||||
get_verification_instructions() # Get DNS instructions
|
||||
|
||||
# Private Helpers
|
||||
_get_vendor_by_id_or_raise() # Vendor lookup
|
||||
_check_domain_limit() # Enforce max domains
|
||||
_domain_exists() # Check uniqueness
|
||||
_validate_domain_format() # Format validation
|
||||
_unset_primary_domains() # Primary domain logic
|
||||
```
|
||||
|
||||
**Service Pattern:**
|
||||
- All database operations in service layer
|
||||
- Raises custom exceptions (not HTTPException)
|
||||
- Transaction management (commit/rollback)
|
||||
- Comprehensive logging
|
||||
- Helper methods with `_` prefix for internal use
|
||||
|
||||
### 4. API Endpoints (`app/api/v1/admin/vendor_domains.py`)
|
||||
|
||||
HTTP layer for domain management:
|
||||
|
||||
```python
|
||||
# Endpoints
|
||||
POST /vendors/{vendor_id}/domains # Add domain
|
||||
GET /vendors/{vendor_id}/domains # List domains
|
||||
GET /vendors/domains/{domain_id} # Get domain
|
||||
PUT /vendors/domains/{domain_id} # Update domain
|
||||
DELETE /vendors/domains/{domain_id} # Delete domain
|
||||
POST /vendors/domains/{domain_id}/verify # Verify ownership
|
||||
GET /vendors/domains/{domain_id}/verification-instructions # Get instructions
|
||||
```
|
||||
|
||||
**Endpoint Pattern:**
|
||||
- Only handle HTTP concerns (request/response)
|
||||
- Delegate business logic to service layer
|
||||
- Use Pydantic schemas for validation
|
||||
- Proper dependency injection
|
||||
- Comprehensive docstrings
|
||||
- No direct database access
|
||||
|
||||
## Comparison: Old vs New
|
||||
|
||||
### Old Implementation Issues
|
||||
|
||||
```python
|
||||
# ❌ Mixed concerns
|
||||
@router.post("/{vendor_id}/domains")
|
||||
def add_vendor_domain(...):
|
||||
# Validation in endpoint
|
||||
domain = VendorDomain.normalize_domain(domain_data.domain)
|
||||
|
||||
# Business logic in endpoint
|
||||
if not domain or '/' in domain:
|
||||
raise HTTPException(400, "Invalid domain")
|
||||
|
||||
# Database operations in endpoint
|
||||
existing = db.query(VendorDomain).filter(...).first()
|
||||
if existing:
|
||||
raise HTTPException(409, "Domain exists")
|
||||
|
||||
# Direct database access
|
||||
domain = VendorDomain(...)
|
||||
db.add(domain)
|
||||
db.commit()
|
||||
```
|
||||
|
||||
**Problems:**
|
||||
- Business logic mixed with HTTP layer
|
||||
- HTTPException instead of custom exceptions
|
||||
- No service layer separation
|
||||
- Direct database access in endpoints
|
||||
- Validation scattered across endpoint
|
||||
- Hard to test business logic
|
||||
|
||||
### New Implementation
|
||||
|
||||
```python
|
||||
# ✅ Proper separation
|
||||
|
||||
# Endpoint (HTTP layer only)
|
||||
@router.post("/{vendor_id}/domains", response_model=VendorDomainResponse)
|
||||
def add_vendor_domain(
|
||||
vendor_id: int = Path(..., gt=0),
|
||||
domain_data: VendorDomainCreate = Body(...), # Pydantic validation
|
||||
db: Session = Depends(get_db),
|
||||
current_admin: User = Depends(get_current_admin_user),
|
||||
):
|
||||
"""Add domain - delegates to service layer"""
|
||||
domain = vendor_domain_service.add_domain(db, vendor_id, domain_data)
|
||||
return VendorDomainResponse(...mapping...)
|
||||
|
||||
# Service (Business logic)
|
||||
class VendorDomainService:
|
||||
def add_domain(self, db, vendor_id, domain_data):
|
||||
"""Business logic and database operations"""
|
||||
# Verify vendor
|
||||
vendor = self._get_vendor_by_id_or_raise(db, vendor_id)
|
||||
|
||||
# Check limits
|
||||
self._check_domain_limit(db, vendor_id)
|
||||
|
||||
# Validate format
|
||||
self._validate_domain_format(normalized_domain)
|
||||
|
||||
# Check uniqueness
|
||||
if self._domain_exists(db, normalized_domain):
|
||||
raise VendorDomainAlreadyExistsException(...) # Custom exception
|
||||
|
||||
# Business logic
|
||||
if domain_data.is_primary:
|
||||
self._unset_primary_domains(db, vendor_id)
|
||||
|
||||
# Database operations
|
||||
new_domain = VendorDomain(...)
|
||||
db.add(new_domain)
|
||||
db.commit()
|
||||
return new_domain
|
||||
|
||||
# Schema (Validation)
|
||||
class VendorDomainCreate(BaseModel):
|
||||
domain: str
|
||||
is_primary: bool = False
|
||||
|
||||
@field_validator('domain')
|
||||
def validate_domain(cls, v: str) -> str:
|
||||
"""Normalize and validate domain"""
|
||||
# Validation logic here
|
||||
return normalized_domain
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- Clean separation of concerns
|
||||
- Custom exceptions with proper status codes
|
||||
- Testable business logic
|
||||
- Reusable service methods
|
||||
- Centralized validation
|
||||
- Easy to maintain
|
||||
|
||||
## Installation Steps
|
||||
|
||||
### 1. Add Exception File
|
||||
|
||||
```bash
|
||||
# Create new exception file
|
||||
app/exceptions/vendor_domain.py
|
||||
```
|
||||
|
||||
Copy content from `vendor_domain_exceptions.py`
|
||||
|
||||
### 2. Update Exception Exports
|
||||
|
||||
```python
|
||||
# app/exceptions/__init__.py
|
||||
from .vendor_domain import (
|
||||
VendorDomainNotFoundException,
|
||||
VendorDomainAlreadyExistsException,
|
||||
# ... other exceptions
|
||||
)
|
||||
|
||||
__all__ = [
|
||||
# ... existing exports
|
||||
"VendorDomainNotFoundException",
|
||||
"VendorDomainAlreadyExistsException",
|
||||
# ... other exports
|
||||
]
|
||||
```
|
||||
|
||||
### 3. Add Pydantic Schemas
|
||||
|
||||
```bash
|
||||
# Create schema file
|
||||
models/schema/vendor_domain.py
|
||||
```
|
||||
|
||||
Copy content from `vendor_domain_schema.py`
|
||||
|
||||
### 4. Add Service Layer
|
||||
|
||||
```bash
|
||||
# Create service file
|
||||
app/services/vendor_domain_service.py
|
||||
```
|
||||
|
||||
Copy content from `vendor_domain_service.py`
|
||||
|
||||
### 5. Replace Endpoint File
|
||||
|
||||
```bash
|
||||
# Replace existing file
|
||||
app/api/v1/admin/vendor_domains.py
|
||||
```
|
||||
|
||||
Copy content from `vendor_domains.py`
|
||||
|
||||
### 6. Install DNS Library
|
||||
|
||||
```bash
|
||||
pip install dnspython
|
||||
```
|
||||
|
||||
Required for DNS verification functionality.
|
||||
|
||||

|
||||
"instructions": {
|
||||
"step1": "Go to your domain's DNS settings",
|
||||
"step2": "Add a new TXT record with the following values:",
|
||||
"step3": "Wait for DNS propagation (5-15 minutes)",
|
||||
"step4": "Click 'Verify Domain' button"
|
||||
},
|
||||
"txt_record": {
|
||||
"type": "TXT",
|
||||
"name": "_letzshop-verify",
|

|
||||
# Step 2: Vendor adds DNS record
|
||||
# _letzshop-verify.myshop.com TXT "abc123xyz..."
|
||||
|
||||
# Step 3: Verify domain
|
||||
POST /api/v1/admin/vendors/domains/1/verify
|
||||
|
||||
# Response (200)
|
||||
{
|
||||
"message": "Domain myshop.com verified successfully",
|
||||
"domain": "myshop.com",
|
||||
"verified_at": "2025-01-15T10:15:00Z",
|
||||
"is_verified": true
|
||||
}
|
||||
```
|
||||
|
||||
### Activating Domain

## Testing
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```python
|
||||
# tests/unit/services/test_vendor_domain_service.py
|
||||
def test_add_domain_success(db_session):
|
||||
"""Test successful domain addition"""
|
||||
service = VendorDomainService()
|
||||
domain_data = VendorDomainCreate(
|
||||
domain="test.com",
|
||||
is_primary=True
|
||||
)
|
||||
|
||||
domain = service.add_domain(db_session, vendor_id=1, domain_data=domain_data)
|
||||
|
||||
assert domain.domain == "test.com"
|
||||
assert domain.is_primary is True
|
||||
assert domain.is_verified is False
|
||||
|
||||
|
||||
def test_add_domain_already_exists(db_session):
|
||||
"""Test adding duplicate domain raises exception"""
|
||||
service = VendorDomainService()
|
||||
|
||||
with pytest.raises(VendorDomainAlreadyExistsException):
|
||||
service.add_domain(db_session, vendor_id=1, domain_data=...)
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
```python
|
||||
# tests/integration/api/test_vendor_domains.py
|
||||
def test_add_domain_endpoint(client, admin_headers):
|
||||
"""Test domain addition endpoint"""
|
||||
response = client.post(
|
||||
"/api/v1/admin/vendors/1/domains",
|
||||
json={"domain": "newshop.com", "is_primary": False},
|
||||
headers=admin_headers
|
||||
)
|
||||
|
||||
assert response.status_code == 201
|
||||
data = response.json()
|
||||
assert data["domain"] == "newshop.com"
|
||||
assert data["is_verified"] is False
|
||||
|
||||
|
||||
def test_verify_domain_not_found(client, admin_headers):
|
||||
"""Test verification with non-existent domain"""
|
||||
response = client.post(
|
||||
"/api/v1/admin/vendors/domains/99999/verify",
|
||||
headers=admin_headers
|
||||
)
|
||||
|
||||
assert response.status_code == 404
|
||||
assert response.json()["error_code"] == "VENDOR_DOMAIN_NOT_FOUND"
|
||||
```
|
||||
|
||||
## Benefits of This Architecture
|
||||
|
||||
### 1. Maintainability
|
||||
- Clear separation makes code easy to understand
|
||||
- Changes isolated to appropriate layers
|
||||
- Easy to locate and fix bugs
|
||||
|
||||
### 2. Testability
|
||||
- Service layer can be unit tested independently
|
||||
- Mock dependencies easily
|
||||
- Integration tests for endpoints
|
||||
|
||||
### 3. Reusability
|
||||
- Service methods can be called from anywhere
|
||||
- Schemas reused across endpoints
|
||||
- Exceptions standardized
|
||||
|
||||
### 4. Scalability
|
||||
- Add new endpoints without duplicating logic
|
||||
- Extend service layer for new features
|
||||
- Easy to add caching, queuing, etc.
|
||||
|
||||
### 5. Error Handling
|
||||
- Consistent error responses
|
||||
- Proper HTTP status codes
|
||||
- Detailed error information for debugging
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Database Migration**: Create migration for vendor_domains table if not exists
|
||||
2. **Middleware Update**: Update vendor detection middleware to check custom domains
|
||||
3. **Frontend Integration**: Build UI for domain management
|
||||
4. **SSL Automation**: Add automatic SSL certificate provisioning
|
||||
5. **Monitoring**: Add logging and monitoring for domain operations
|
||||
6. **Rate Limiting**: Implement rate limits for domain additions
|
||||
7. **Webhooks**: Add webhooks for domain status changes
|
||||
|
||||

|
||||
|
||||
This refactored implementation follows your application's architecture patterns:
|
||||
- ✅ Proper separation of concerns
