Samir Boulahtit 7a9dda282d refactor(scripts): reorganize scripts/ into seed/ and validate/ subfolders
Move 9 init/seed scripts into scripts/seed/ and 7 validation scripts
(+ validators/ subfolder) into scripts/validate/ to reduce clutter in
the root scripts/ directory. Update all references across Makefile,
CI/CD configs, pre-commit hooks, docs (~40 files), and Python imports.

## 1. API Layer Fixes
### 1.1 Store Settings API
**File:** `app/api/v1/store/settings.py`
**Problem:** 10 HTTPException raises directly in endpoint functions (API-003 violations).
**Solution:** Moved validation to Pydantic field validators.
#### Before (Inline Validation)
```python
@router.put("/letzshop")
def update_letzshop_settings(letzshop_config: LetzshopFeedSettingsUpdate, ...):
update_data = letzshop_config.model_dump(exclude_unset=True)
# Validate tax rate - VIOLATION: HTTPException in endpoint
if "letzshop_default_tax_rate" in update_data:
if update_data["letzshop_default_tax_rate"] not in VALID_TAX_RATES:
raise HTTPException(status_code=400, detail="Invalid tax rate")
# ... more inline validation
```
#### After (Pydantic Validators)
```python
# Constants moved above model
VALID_TAX_RATES = [0, 3, 8, 14, 17]
VALID_DELIVERY_METHODS = ["nationwide", "package_delivery", "self_collect"]
class LetzshopFeedSettingsUpdate(BaseModel):
letzshop_default_tax_rate: int | None = Field(None)
letzshop_boost_sort: str | None = Field(None)
letzshop_delivery_method: str | None = Field(None)
letzshop_preorder_days: int | None = Field(None, ge=0) # Built-in validation
@field_validator("letzshop_default_tax_rate")
@classmethod
def validate_tax_rate(cls, v: int | None) -> int | None:
if v is not None and v not in VALID_TAX_RATES:
raise ValueError(f"Invalid tax rate. Must be one of: {VALID_TAX_RATES}")
return v
@field_validator("letzshop_delivery_method")
@classmethod
def validate_delivery_method(cls, v: str | None) -> str | None:
if v is not None:
methods = v.split(",")
for method in methods:
if method.strip() not in VALID_DELIVERY_METHODS:
raise ValueError(f"Invalid delivery method")
return v
@field_validator("letzshop_boost_sort")
@classmethod
def validate_boost_sort(cls, v: str | None) -> str | None:
if v is not None:
try:
boost = float(v)
if boost < 0.0 or boost > 10.0:
raise ValueError("Boost sort must be between 0.0 and 10.0")
except ValueError as e:
if "could not convert" in str(e).lower():
raise ValueError("Boost sort must be a valid number")
raise
return v
# Endpoint now clean
@router.put("/letzshop")
def update_letzshop_settings(letzshop_config: LetzshopFeedSettingsUpdate, ...):
"""Validation is handled by Pydantic model validators."""
store = store_service.get_store_by_id(db, current_user.token_store_id)
update_data = letzshop_config.model_dump(exclude_unset=True)
for key, value in update_data.items():
setattr(store, key, value)
# ...
```
**Same pattern applied to:**
- `LocalizationSettingsUpdate` - language and locale validation
---
### 1.2 Admin Email Templates API
**File:** `app/api/v1/admin/email_templates.py`
**Problem:** 2 endpoints returning raw dicts instead of Pydantic models (API-001 violations).
**Solution:** Added Pydantic response models.
#### Before
```python
@router.get("")
def list_templates(...):
return {"templates": service.list_platform_templates()}
@router.get("/categories")
def get_categories(...):
return {"categories": service.get_template_categories()}
```
#### After
```python
class TemplateListItem(BaseModel):
code: str
name: str
description: str | None = None
category: str
languages: list[str] # Matches service output
is_platform_only: bool = False
variables: list[str] = []
class Config:
from_attributes = True
class TemplateListResponse(BaseModel):
templates: list[TemplateListItem]
class CategoriesResponse(BaseModel):
categories: list[str]
@router.get("", response_model=TemplateListResponse)
def list_templates(...):
return TemplateListResponse(templates=service.list_platform_templates())
@router.get("/categories", response_model=CategoriesResponse)
def get_categories(...):
return CategoriesResponse(categories=service.get_template_categories())
```
---
### 1.3 Shop Auth API (Password Reset)
**File:** `app/api/v1/shop/auth.py`
**Problem:** Business logic in `forgot_password()` and `reset_password()` endpoints.
**Solution:** Moved business logic to `CustomerService`.
#### Before (Business Logic in Endpoint)
```python
@router.post("/auth/reset-password")
def reset_password(request: Request, reset_token: str, new_password: str, db: Session = Depends(get_db)):
# Validate password length - BUSINESS LOGIC
if len(new_password) < 8:
raise HTTPException(status_code=400, detail="Password too short")
# Find valid token - BUSINESS LOGIC
token_record = PasswordResetToken.find_valid_token(db, reset_token)
if not token_record:
raise HTTPException(status_code=400, detail="Invalid token")
# ... more business logic
```
#### After (Delegated to Service)
```python
@router.post("/auth/reset-password", response_model=PasswordResetResponse)
def reset_password(request: Request, reset_token: str, new_password: str, db: Session = Depends(get_db)):
store = getattr(request.state, "store", None)
if not store:
raise StoreNotFoundException("context", identifier_type="subdomain")
# All business logic in service
customer = customer_service.validate_and_reset_password(
db=db,
store_id=store.id,
reset_token=reset_token,
new_password=new_password,
)
db.commit()
return PasswordResetResponse(message="Password reset successfully.")
```
---
## 2. Service Layer Changes
### 2.1 CustomerService Enhancements
**File:** `app/services/customer_service.py`
Added two new methods for password reset:
```python
def get_customer_for_password_reset(
self, db: Session, store_id: int, email: str
) -> Customer | None:
"""Get active customer by email for password reset."""
return (
db.query(Customer)
.filter(
Customer.store_id == store_id,
Customer.email == email.lower(),
Customer.is_active == True,
)
.first()
)
def validate_and_reset_password(
self,
db: Session,
store_id: int,
reset_token: str,
new_password: str,
) -> Customer:
"""Validate reset token and update customer password.
Raises:
PasswordTooShortException: If password too short
InvalidPasswordResetTokenException: If token invalid/expired
CustomerNotActiveException: If customer not active
"""
if len(new_password) < 8:
raise PasswordTooShortException(min_length=8)
token_record = PasswordResetToken.find_valid_token(db, reset_token)
if not token_record:
raise InvalidPasswordResetTokenException()
customer = db.query(Customer).filter(Customer.id == token_record.customer_id).first()
if not customer or customer.store_id != store_id:
raise InvalidPasswordResetTokenException()
if not customer.is_active:
raise CustomerNotActiveException(customer.email)
hashed_password = self.auth_service.hash_password(new_password)
customer.hashed_password = hashed_password
token_record.mark_used(db)
return customer
```
---
## 3. Exception Layer
### 3.1 New Customer Exceptions
**File:** `app/exceptions/customer.py`
Added two new exceptions for password reset:
```python
class InvalidPasswordResetTokenException(ValidationException):
"""Raised when password reset token is invalid or expired."""
def __init__(self):
super().__init__(
message="Invalid or expired password reset link. Please request a new one.",
field="reset_token",
)
self.error_code = "INVALID_RESET_TOKEN"
class PasswordTooShortException(ValidationException):
"""Raised when password doesn't meet minimum length requirement."""
def __init__(self, min_length: int = 8):
super().__init__(
message=f"Password must be at least {min_length} characters long",
field="password",
details={"min_length": min_length},
)
self.error_code = "PASSWORD_TOO_SHORT"
```
---
## 4. JavaScript Fixes
### 4.1 Admin Email Templates
**File:** `static/admin/js/email-templates.js`
**Problems:**
- Used raw `fetch()` instead of `apiClient`
- Used `showNotification()` instead of `Utils.showToast()`
#### Before
```javascript
async loadData() {
this.loading = true;
try {
const response = await fetch('/api/v1/admin/email-templates');
const data = await response.json();
this.templates = data.templates || [];
} catch (error) {
showNotification('Failed to load templates', 'error');
}
}
```
#### After
```javascript
async loadData() {
this.loading = true;
try {
const [templatesData, categoriesData] = await Promise.all([
apiClient.get('/admin/email-templates'),
apiClient.get('/admin/email-templates/categories')
]);
this.templates = templatesData.templates || [];
this.categories = categoriesData.categories || [];
} catch (error) {
Utils.showToast('Failed to load templates', 'error');
}
}
```
---
### 4.2 Store Email Templates
**File:** `static/store/js/email-templates.js`
**Problems:**
- Used raw `fetch()` instead of `apiClient`
- Missing parent init call pattern
- Used `showNotification()` instead of `Utils.showToast()`
#### Before
```javascript
async init() {
await this.loadData();
}
```
#### After
```javascript
async init() {
storeEmailTemplatesLog.info('Email templates init() called');
// Call parent init to set storeCode and other base state
const parentInit = data().init;
if (parentInit) {
await parentInit.call(this);
}
await this.loadData();
}
```
---
## 5. Template Fixes
### 5.1 Admin Email Templates Template
**File:** `app/templates/admin/email-templates.html`
**Problem:** Wrong block name (TPL-015 violation).
```html
<!-- Before -->
{% block scripts %}
<!-- After -->
{% block extra_scripts %}
```
---
### 5.2 Shop Base Template
**File:** `app/templates/shop/base.html`
**Problem:** `request.state.language` used without default (LANG-009 violation).
```html
<!-- Before -->
language: '{{ request.state.language }}'
<!-- After -->
language: '{{ request.state.language|default("fr") }}'
```
---
## 6. Architecture Validator Fix
### 6.1 LANG-001 False Positive
**File:** `scripts/validate/validate_architecture.py`
**Problem:** Validator flagged "English" as invalid language code in `SUPPORTED_LANGUAGES` dict (where it's a display name, not a code).
**Solution:** Extended pattern to skip `SUPPORTED_LANGUAGES` and `SUPPORTED_LOCALES` blocks.
```python
# Before: Only skipped LANGUAGE_NAMES blocks
if ("LANGUAGE_NAMES" in line or "LANGUAGE_NAMES_EN" in line) and "=" in line:
in_language_names_dict = True
# After: Also skips SUPPORTED_LANGUAGES and SUPPORTED_LOCALES
if any(
name in line
for name in [
"LANGUAGE_NAMES",
"LANGUAGE_NAMES_EN",
"SUPPORTED_LANGUAGES",
"SUPPORTED_LOCALES",
]
) and "=" in line:
in_language_names_block = True
if in_language_names_block and stripped in ("}", "]"):
in_language_names_block = False
```

## Architecture Rules Reference
| Rule ID | Description | Fixed Files |
|---------|-------------|-------------|
| API-001 | Endpoint must use Pydantic models | admin/email_templates.py |
| API-003 | Endpoint must NOT contain business logic | store/settings.py, shop/auth.py |
| JS-001 | Must use apiClient for API calls | email-templates.js (admin & store) |
| JS-002 | Must use Utils.showToast() for notifications | email-templates.js (admin & store) |
| JS-003 | Must call parent init for Alpine components | store/email-templates.js |
| TPL-015 | Must use correct block names | admin/email-templates.html |
| LANG-009 | Must provide language default | shop/base.html |
---
## Testing
After these changes:
```bash
$ python scripts/validate/validate_architecture.py
Files checked: 439
Findings: 0 errors, 141 warnings, 2 info
```
The remaining warnings are acceptable patterns (mostly `db.commit()` in services which is allowed for complex operations).
