</td>
</tr>
</tbody>
</table>
</div>
```
### Form with Validation

Operation completed successfully!
</div>
```
### Loading State
```html
<button class="btn btn-primary" disabled>
<span class="loading-spinner"></span>
Processing...
</button>
```
---
## 🎯 Class Combinations

## 🎨 Color Classes
### Text Colors
- `text-primary` - Primary brand color
- `text-success` - Green (success)
- `text-danger` - Red (error/delete)
- `text-warning` - Yellow (warning)
- `text-muted` - Gray (less important)
### Background Badges
- `badge-success` - Green badge
- `badge-danger` - Red badge
- `badge-warning` - Yellow badge
- `badge-info` - Blue badge
- `badge-secondary` - Gray badge
---
## 📏 Spacing Utilities
### Margin
- `mt-{0-4}` - Margin top
- `mb-{0-4}` - Margin bottom
- `ml-{0-4}` - Margin left
- `mr-{0-4}` - Margin right
### Padding
- `p-{0-4}` - Padding all sides
- `pt-{0-4}` - Padding top
- `pb-{0-4}` - Padding bottom
Example:
```html
<div class="mt-3 mb-2 p-3">
<!-- margin-top: 24px, margin-bottom: 16px, padding: 24px -->
</div>
```
---
## 🔤 Typography
### Headings
```html
<h1>Largest Heading</h1> <!-- 32px -->
<h2>Large Heading</h2> <!-- 24px -->
<h3>Medium Heading</h3> <!-- 20px -->
<h4>Small Heading</h4> <!-- 18px -->
```
### Font Weights
- `font-bold` - 700 weight
- `font-semibold` - 600 weight
- `font-normal` - 400 weight
---
## 📱 Responsive Classes
### Display
- `d-none` - Hide element
- `d-block` - Display as block
- `d-flex` - Display as flexbox
### Flexbox
- `justify-start` - Align left
- `justify-end` - Align right
- `justify-center` - Center
- `justify-between` - Space between
- `align-center` - Vertical center
- `gap-{1-3}` - Gap between items
---
## 🎭 States
### Show/Hide
```javascript
// Show element
element.classList.add('show');
// Hide element
element.classList.remove('show');
```
### Enable/Disable Button
```javascript
// Disable
button.disabled = true;
button.innerHTML = '<span class="loading-spinner"></span>Loading...';
// Enable
button.disabled = false;
button.innerHTML = 'Submit';
```
### Show Error
```javascript
// Add error to input
input.classList.add('error');
errorMessage.classList.add('show');
errorMessage.textContent = 'This field is required';
// Clear error
input.classList.remove('error');
errorMessage.classList.remove('show');
```
---
## 🔧 CSS Variables Usage
### In CSS
```css
.custom-button {
background: var(--primary-color);
padding: var(--spacing-md);
border-radius: var(--radius-lg);
color: white;
}
```
### In JavaScript
```javascript
// Get value
const primaryColor = getComputedStyle(document.documentElement)
.getPropertyValue('--primary-color');
// Set value
document.documentElement.style
.setProperty('--primary-color', '#ff0000');
```
---
## 🎨 Brand Customization
### Quick Brand Color Change
Edit `static/css/shared/base.css`:
```css
:root {
--primary-color: #YOUR_COLOR;
--primary-dark: #DARKER_SHADE;
}
```
### Per-Vendor Theming
Create `static/css/vendor/themes/VENDOR_CODE.css`:
```css
:root {
--primary-color: #VENDOR_COLOR;
}
```
Load in HTML:
```html
<link rel="stylesheet" href="/static/css/vendor/themes/techstore.css">
```
---
## ⚡ Performance Tips
### CSS Loading
```html
<!-- Preload critical CSS -->
<link rel="preload" href="/static/css/shared/base.css" as="style">
<link rel="stylesheet" href="/static/css/shared/base.css">
```
### Minimize Repaints
```css
/* Use transform instead of position changes */
.animate {
transform: translateY(-4px);
transition: transform 0.2s;
}
```
---
## 🐛 Common Issues
### Issue: Styles not applying
**Solution**: Check CSS is loaded in correct order (base.css first)
### Issue: Button not clickable
**Solution**: Check z-index and pointer-events
### Issue: Layout breaks on mobile
**Solution**: Add viewport meta tag:
```html
<meta name="viewport" content="width=device-width, initial-scale=1.0">
```
### Issue: Colors look wrong
**Solution**: Ensure base.css is loaded (contains CSS variables)

```css
:root {
/* Change these to your brand colors */
--primary-color: #667eea; /* Your primary color */
--primary-dark: #764ba2; /* Darker shade */

body {
font-family: 'Your Font', -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif;
}
```
### Changing Border Radius (Rounded Corners)
```css
:root {

### Adding Vendor-Specific Themes
Create a new file: `static/css/vendor/themes/{vendor_code}.css`
```css
/* static/css/vendor/themes/techstore.css */
:root {
--primary-color: #ff6b6b;
--primary-dark: #ee5a52;
}
.vendor-header {
background: linear-gradient(135deg, var(--primary-color), var(--primary-dark));
color: white;
}
```
Then in vendor pages:
```html
<link rel="stylesheet" href="/static/css/vendor/themes/techstore.css">
```

---
## ✅ Installation Checklist
- [ ] Create `static/css/shared/` directory
- [ ] Create `static/css/admin/` directory
- [ ] Create `static/css/vendor/` directory
- [ ] Copy `base.css` to `static/css/shared/`
- [ ] Copy `auth.css` to `static/css/shared/`
- [ ] Copy `admin.css` to `static/css/admin/`

- [ ] Update all HTML files with correct `<link>` tags
- [ ] Test pages load with styles
- [ ] Test responsive design (resize browser)
- [ ] Test in multiple browsers
---
## 🔍 Troubleshooting
### Styles Not Loading
**Check**:
1. File paths are correct in HTML `<link>` tags
2. FastAPI is serving static files: `app.mount("/static", StaticFiles(directory="static"), name="static")`
3. Browser cache - try hard refresh (Ctrl+F5)
4. Browser console for 404 errors
### Styles Look Wrong
**Check**:
1. CSS files are in correct order (base.css first)
2. No conflicting inline styles in HTML
3. Browser DevTools to inspect element styles
4. CSS variables are defined in `:root`
### Mobile Layout Broken
**Check**:
1. Viewport meta tag in HTML: `<meta name="viewport" content="width=device-width, initial-scale=1.0">`
2. Responsive classes are applied
3. Test in actual devices, not just browser resize
---
## 📚 Additional Resources

# Quick Start Guide - Slice 1
## Get Your Multi-Tenant Platform Running in 15 Minutes
This guide gets Slice 1 up and running quickly so you can test the complete admin → vendor creation → vendor login flow.
## 🎯 What You'll Accomplish
By the end of this guide, you'll be able to:
1. ✅ Login as super admin
2. ✅ Create vendors with auto-generated owner accounts
3. ✅ Login as vendor owner
4. ✅ See vendor-specific dashboard
5. ✅ Verify vendor isolation works
## 📦 Prerequisites Checklist
Before starting, ensure you have:
```bash
# Check Python version (need 3.11+)
python --version
# Check PostgreSQL is running
psql --version
# Check you have the project files
ls main.py # Should exist
```
## ⚡ 5-Step Setup
### Step 1: Install Dependencies (2 minutes)
```bash
# Create virtual environment
python -m venv venv
# Activate it
source venv/bin/activate # macOS/Linux
# OR
venv\Scripts\activate # Windows
# Install requirements
pip install fastapi uvicorn sqlalchemy psycopg2-binary python-jose passlib bcrypt python-multipart
```
### Step 2: Configure Database (3 minutes)
```bash
# Create .env file
cat > .env << 'EOF'
# Database
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/multitenant_ecommerce
# JWT Security
JWT_SECRET_KEY=your-super-secret-key-change-this-in-production-please
JWT_EXPIRE_MINUTES=30
# Server
SERVER_ADDRESS=http://localhost:8000
DEBUG=True
PROJECT_NAME=Multi-Tenant Ecommerce Platform
ALLOWED_HOSTS=["*"]
EOF
# Create database
createdb multitenant_ecommerce
# Or using psql:
# psql -U postgres -c "CREATE DATABASE multitenant_ecommerce;"
```
### Step 3: Initialize Database (3 minutes)
Create `scripts/init_db.py`:
```python
# scripts/init_db.py
import sys
sys.path.append('.')
from app.core.database import Base, engine
from models.database.user import User
from models.database.vendor import Vendor, Role, VendorUser
from middleware.auth import AuthManager
def init_database():
"""Initialize database with tables and admin user"""
print("🔧 Creating database tables...")
Base.metadata.create_all(bind=engine)
print("✅ Tables created successfully")
# Create admin user
from sqlalchemy.orm import Session
db = Session(bind=engine)
try:
admin = db.query(User).filter(User.username == "admin").first()
if not admin:
auth_manager = AuthManager()
admin = User(
email="admin@platform.com",
username="admin",
hashed_password=auth_manager.hash_password("admin123"),
role="admin",
is_active=True
)
db.add(admin)
db.commit()
print("\n✅ Admin user created:")
print(" 📧 Email: admin@platform.com")
print(" 👤 Username: admin")
print(" 🔑 Password: admin123")
else:
print("\n Admin user already exists")
print("\n🎉 Database initialization complete!")
print("\n🚀 Next steps:")
print(" 1. Run: uvicorn main:app --reload")
print(" 2. Visit: http://localhost:8000/static/admin/login.html")
finally:
db.close()
if __name__ == "__main__":
init_database()
```
Run it:
```bash
python scripts/init_db.py
```
### Step 4: Create Directory Structure (2 minutes)
```bash
# Create required directories
mkdir -p static/admin
mkdir -p static/vendor
mkdir -p static/js/shared
mkdir -p static/css/admin
mkdir -p static/css/shared
```
Copy the HTML/JS files I created into these directories:
- `static/admin/login.html`
- `static/admin/dashboard.html`
- `static/admin/vendors.html`
- `static/vendor/login.html`
- `static/vendor/dashboard.html`
- `static/js/shared/api-client.js`
### Step 5: Start the Application (1 minute)
```bash
# Start FastAPI server
uvicorn main:app --reload --port 8000
```
You should see:
```
INFO: Uvicorn running on http://127.0.0.1:8000
INFO: Application startup complete.
```
## 🧪 Test the Complete Flow (5 minutes)
### Test 1: Admin Login
1. **Open browser**: http://localhost:8000/static/admin/login.html
2. **Login**:
- Username: `admin`
- Password: `admin123`
3. **Expected**: Redirected to admin dashboard
### Test 2: Create Vendor
1. **Click**: "Create New Vendor" button
2. **Fill form**:
```
Vendor Code: TECHSTORE
Name: Tech Store Luxembourg
Subdomain: techstore
Owner Email: owner@techstore.com
(Leave other fields optional)
```
3. **Submit**: Click "Create Vendor"
4. **Expected**: Success message with credentials displayed
### Test 3: Copy Vendor Credentials
**IMPORTANT**: Copy these credentials immediately (they're shown only once):
```
Vendor Code: TECHSTORE
Subdomain: techstore
Owner Username: techstore_owner
Owner Email: owner@techstore.com
Temporary Password: [COPY THIS!]
```
### Test 4: Vendor Login (Path-based)
1. **Open new tab**: http://localhost:8000/vendor/techstore/login
2. **Login**:
- Username: `techstore_owner`
- Password: [paste the temporary password]
3. **Expected**: Redirected to vendor dashboard
4. **Verify**: Dashboard shows "TECHSTORE Dashboard"
### Test 5: Verify Isolation
1. **Try accessing different vendor**: http://localhost:8000/vendor/otherstore/login
2. **Expected**: "Vendor Not Found" message
3. **Database check**:
```sql
SELECT * FROM vendors WHERE vendor_code = 'TECHSTORE';
SELECT * FROM users WHERE email = 'owner@techstore.com';
```
## ✅ Success Indicators
You know Slice 1 is working when:
- [x] Admin can login and see dashboard
- [x] Admin can create vendors
- [x] Vendor owner credentials are generated
- [x] Vendor owner can login
- [x] Vendor dashboard shows correct vendor context
- [x] Invalid vendor URLs show error message
- [x] Each vendor is completely isolated
## 🐛 Common Issues & Fixes
### Issue: "Module not found" errors
**Fix**:
```bash
pip install -r requirements.txt
# Or install missing packages individually
pip install fastapi sqlalchemy psycopg2-binary
```
### Issue: Database connection fails
**Fix**:
```bash
# Check PostgreSQL is running
sudo service postgresql status
# Check database exists
psql -U postgres -l | grep multitenant
# Update DATABASE_URL in .env to match your setup
```
### Issue: "401 Unauthorized" in browser console
**Fix**:
```javascript
// Open browser console (F12)
// Check token exists:
localStorage.getItem('admin_token')
// If null, login again
// If exists but still fails, token might be expired - login again
```
### Issue: Admin login redirects to login page
**Fix**:
```bash
# Check admin user exists in database:
psql -U postgres -d multitenant_ecommerce -c "SELECT * FROM users WHERE role='admin';"
# If no results, run:
python scripts/init_db.py
```
### Issue: Vendor context not detected
**Fix**:
Check URL format:
- ✅ Correct: `localhost:8000/vendor/techstore/login`
- ❌ Wrong: `localhost:8000/techstore/login`
- ❌ Wrong: `localhost:8000/vendor/login`
### Issue: Static files not loading (404)
**Fix**:
```python
# Verify main.py has static file mounting:
from fastapi.staticfiles import StaticFiles
app.mount("/static", StaticFiles(directory="static"), name="static")
```
## 📊 Database Verification
Check everything was created correctly:
```sql
-- Connect to database
psql -U postgres -d multitenant_ecommerce
-- Check tables
\dt
-- Check admin user
SELECT id, username, email, role FROM users WHERE role = 'admin';
-- Check created vendor
SELECT id, vendor_code, name, subdomain, is_active, is_verified
FROM vendors;
-- Check vendor owner
SELECT id, username, email, role
FROM users WHERE email LIKE '%techstore%';
-- Check default roles were created
SELECT id, name, vendor_id
FROM roles
WHERE vendor_id = (SELECT id FROM vendors WHERE vendor_code = 'TECHSTORE');
```
Expected results:
- 1 admin user
- 1 vendor (TECHSTORE)
- 1 vendor owner user
- 4 roles (Owner, Manager, Editor, Viewer)
## 🎯 Next Steps
Once Slice 1 is working:
### Option 1: Create More Vendors
Test multi-tenancy by creating multiple vendors:
1. Create `FASHIONSTORE` vendor
2. Create `BOOKSHOP` vendor
3. Verify each has isolated login and dashboard
### Option 2: Proceed to Slice 2
Move on to **Slice 2: Marketplace Product Import**:
- Implement CSV import functionality
- Create MarketplaceProduct staging table
- Build import UI
- Add Celery for background processing
### Option 3: Customize UI
Enhance the frontend:
- Add custom CSS themes
- Improve dashboard widgets
- Add vendor statistics
- Build team management UI

## 🔒 Security Notes
### For Development
Current setup uses:
- ✅ JWT tokens with bcrypt password hashing
- ✅ HttpOnly would be recommended for production cookies
- ✅ CORS middleware configured
- ⚠️ Default admin password (change immediately!)
- ⚠️ DEBUG=True (disable in production)
### For Production
Before going live:
1. **Change default credentials**:
```sql
UPDATE users SET hashed_password = 'new_hash' WHERE username = 'admin';
```
2. **Update environment variables**:
```bash
DEBUG=False
JWT_SECRET_KEY=[generate strong random key]
ALLOWED_HOSTS=["yourdomain.com"]
```
3. **Enable HTTPS**:
- Use nginx/apache with SSL certificates
- Force HTTPS redirects
- Set secure cookie flags
4. **Set up subdomain routing**:
- Configure DNS wildcards: `*.platform.com`
- Update nginx to route subdomains
- Test subdomain detection

# Slice 1 Implementation Guide
## Admin Creates Vendor → Vendor Owner Logs In
This guide provides complete instructions for implementing Slice 1 of the multi-tenant ecommerce platform.
## ✅ What We've Built
### Backend Components
1. **Enhanced Admin Service** (`app/services/admin_service.py`)
- `create_vendor_with_owner()` - Creates vendor + owner user + default roles
- Generates secure temporary password
- Auto-verifies admin-created vendors
2. **Enhanced Admin API** (`app/api/v1/admin.py`)
- `POST /admin/vendors` - Create vendor with owner
- `GET /admin/vendors` - List vendors with filtering
- `GET /admin/dashboard` - Dashboard statistics
- `PUT /admin/vendors/{id}/verify` - Verify vendor
- `PUT /admin/vendors/{id}/status` - Toggle vendor status
3. **Vendor Schema Updates** (`models/schemas/vendor.py`)
- Added `owner_email` field to `VendorCreate`
- Created `VendorCreateResponse` with credentials
4. **Vendor Context Middleware** (`middleware/vendor_context.py`)
- Subdomain detection (production)
- Path-based detection (development)
- Vendor isolation enforcement
### Frontend Components
1. **Admin Login Page** (`static/admin/login.html`)
- Clean, modern UI
- JWT authentication
- Role validation (admin only)
2. **Admin Dashboard** (`static/admin/dashboard.html`)
- Statistics overview
- Recent vendors list
- Recent import jobs
- Navigation to all sections
3. **Vendor Creation Page** (`static/admin/vendors.html`)
- Complete vendor creation form
- Auto-formatting inputs
- Displays generated credentials
- One-time password display
4. **API Client Utility** (`static/js/shared/api-client.js`)
- Authenticated API calls
- Token management
- Error handling
- Utility functions
## 📋 Prerequisites
Before implementing Slice 1, ensure you have:
- ✅ PostgreSQL database running
- ✅ Python 3.11+ with FastAPI
- ✅ All dependencies installed (`pip install -r requirements.txt`)
-`.env` file configured with database URL and JWT secret
## 🚀 Implementation Steps
### Step 1: Update Database Models
Ensure your `models/database/vendor.py` includes:
```python
class Vendor(Base, TimestampMixin):
__tablename__ = "vendors"
id = Column(Integer, primary_key=True, index=True)
vendor_code = Column(String, unique=True, nullable=False, index=True)
subdomain = Column(String(100), unique=True, nullable=False, index=True)
name = Column(String, nullable=False)
description = Column(Text)
owner_user_id = Column(Integer, ForeignKey("users.id"), nullable=False)
# Business information
business_email = Column(String)
business_phone = Column(String)
contact_email = Column(String)
contact_phone = Column(String)
website = Column(String)
business_address = Column(Text)
tax_number = Column(String)
# Status flags
is_active = Column(Boolean, default=True)
is_verified = Column(Boolean, default=False)
verified_at = Column(DateTime, nullable=True)
# Theme and configuration
theme_config = Column(JSON, default=dict)
# CSV URLs for marketplace integration
letzshop_csv_url_fr = Column(String)
letzshop_csv_url_en = Column(String)
letzshop_csv_url_de = Column(String)
# Relationships
owner = relationship("User", back_populates="owned_vendors")
```
### Step 2: Create Database Migration
Create a new Alembic migration:
```bash
# Generate migration
alembic revision --autogenerate -m "Add vendor and role tables for slice 1"
# Review the generated migration file
# Then apply it:
alembic upgrade head
```
### Step 3: Create Default Admin User
Run the script to create initial admin:
```python
# scripts/create_admin.py
from sqlalchemy.orm import Session
from app.core.database import SessionLocal
from middleware.auth import AuthManager
from models.database.user import User
def create_admin():
db = SessionLocal()
auth_manager = AuthManager()
# Check if admin exists
admin = db.query(User).filter(User.username == "admin").first()
if not admin:
admin = User(
email="admin@platform.com",
username="admin",
hashed_password=auth_manager.hash_password("admin123"),
role="admin",
is_active=True
)
db.add(admin)
db.commit()
print("✅ Admin user created:")
print(" Username: admin")
print(" Password: admin123")
print(" Email: admin@platform.com")
else:
print(" Admin user already exists")
db.close()
if __name__ == "__main__":
create_admin()
```
Run it:
```bash
python scripts/create_admin.py
```
### Step 4: Deploy Frontend Files
Ensure the following structure exists:
```
static/
├── admin/
│ ├── login.html
│ ├── dashboard.html
│ └── vendors.html
├── js/
│ └── shared/
│ └── api-client.js
└── css/
├── shared/
│ └── base.css
└── admin/
└── admin.css
```
### Step 5: Update API Router
Ensure `app/api/main.py` includes admin routes:
```python
from app.api.v1 import admin
api_router.include_router(
admin.router,
prefix="/admin",
tags=["admin"]
)
```
### Step 6: Start the Application
```bash
# Start the server
uvicorn main:app --reload --port 8000
# Or with hot reload
python main.py
```
### Step 7: Test the Flow
#### 7.1 Admin Login
1. Navigate to `http://localhost:8000/static/admin/login.html`
2. Login with:
- Username: `admin`
- Password: `admin123`
3. Should redirect to dashboard
#### 7.2 Create Vendor
1. Click "Create New Vendor" button
2. Fill in the form:
- Vendor Code: `TECHSTORE`
- Name: `Tech Store Luxembourg`
- Subdomain: `techstore`
- Owner Email: `owner@techstore.com`
3. Submit the form
4. **Save the displayed credentials!**
#### 7.3 Verify Vendor Creation
1. Check database:
```sql
SELECT * FROM vendors WHERE vendor_code = 'TECHSTORE';
SELECT * FROM users WHERE email = 'owner@techstore.com';
SELECT * FROM roles WHERE vendor_id = (SELECT id FROM vendors WHERE vendor_code = 'TECHSTORE');
```
2. Check admin dashboard - vendor should appear in "Recent Vendors"
## 🧪 Testing Checklist
### Admin Interface Tests
- [ ] Admin can login with correct credentials
- [ ] Admin login rejects non-admin users
- [ ] Dashboard displays vendor statistics
- [ ] Dashboard displays user statistics
- [ ] Recent vendors list shows newest vendors
- [ ] Vendor creation form validates inputs
- [ ] Vendor code is auto-uppercased
- [ ] Subdomain is auto-lowercased
- [ ] Duplicate vendor code is rejected
- [ ] Duplicate subdomain is rejected
- [ ] Generated credentials are displayed once
- [ ] Admin can view all vendors
- [ ] Admin can verify/unverify vendors
- [ ] Admin can activate/deactivate vendors
### Vendor Context Tests
- [ ] Subdomain detection works: `vendor.localhost:8000`
- [ ] Path detection works: `localhost:8000/vendor/vendorname/`
- [ ] Admin routes are excluded from vendor context
- [ ] API routes are excluded from vendor context
- [ ] Invalid vendor returns 404
### Database Tests
- [ ] Vendor record created correctly
- [ ] Owner user record created
- [ ] Owner has correct relationship to vendor
- [ ] Default roles created (Owner, Manager, Editor, Viewer)
- [ ] Vendor is auto-verified when created by admin
- [ ] Timestamps are set correctly
## 🔐 Security Considerations
1. **Password Security**
- Temporary passwords are 12+ characters
- Include letters, numbers, and symbols
- Hashed with bcrypt before storage
- Displayed only once
2. **Admin Access Control**
- JWT token required for all admin endpoints
- Role validation on every request
- Token expiration enforced
3. **Vendor Isolation**
- Vendor context middleware enforces boundaries
- All queries filtered by vendor_id
- Cross-vendor access prevented
## 📝 Configuration
### Environment Variables
```bash
# Database
DATABASE_URL=postgresql://user:pass@localhost:5432/dbname
# JWT
JWT_SECRET_KEY=your-secret-key-change-in-production
JWT_EXPIRE_MINUTES=30
# Server
SERVER_ADDRESS=http://localhost:8000
DEBUG=True
# Platform
PROJECT_NAME="Multi-Tenant Ecommerce Platform"
ALLOWED_HOSTS=["*"]
```
### Development vs Production
**Development Mode** (path-based):
```
http://localhost:8000/vendor/techstore/
http://localhost:8000/admin/
```
**Production Mode** (subdomain-based):
```
https://techstore.platform.com/
https://admin.platform.com/
```
## 🐛 Troubleshooting
### Issue: Admin login fails
**Solution**: Check that admin user exists and role is "admin"
```python
python scripts/create_admin.py
```
### Issue: Vendor creation returns 401
**Solution**: Check that JWT token is valid and not expired
```javascript
// In browser console
localStorage.getItem('admin_token')
```
### Issue: Vendor context not detected
**Solution**: Check middleware is registered in `main.py`:
```python
app.middleware("http")(vendor_context_middleware)
```
### Issue: Database foreign key error
**Solution**: Run migrations in correct order:
```bash
alembic upgrade head
```
## 📊 Success Metrics
Slice 1 is complete when:
- [x] Admin can log into admin interface
- [x] Admin can create new vendors
- [x] System generates vendor owner credentials
- [x] Vendor owner can log into vendor-specific interface
- [x] Vendor context detection works in dev and production modes
- [x] Database properly isolates vendor data
- [x] All tests pass
- [x] Documentation is complete
## 🎯 Next Steps - Slice 2
Once Slice 1 is complete and tested, proceed to **Slice 2: Vendor Imports Products from Letzshop**:
1. Implement marketplace CSV import
2. Create MarketplaceProduct staging table
3. Build product import UI
4. Add background job processing with Celery
5. Create import job monitoring
## 💡 Tips
1. **Always test in order**: Admin login → Vendor creation → Context detection
2. **Save credentials immediately**: Password is shown only once
3. **Use browser dev tools**: Check console for API errors
4. **Check database directly**: Verify data is created correctly
5. **Test both detection modes**: Path-based (dev) and subdomain (prod)
