FastAPI Router

Create FastAPI routers following established patterns with proper authentication, response models, and HTTP status codes.

Authorization requirements

The template assumes an author_id owner field; adapt it to the real model before use. Update/delete checks are required, not optional. For non-public resources require authentication and tenant/owner filtering on list/get too, preferably in atomic service queries; authentication alone is not authorization. Test anonymous access, another owner and another tenant against every CRUD route. The placeholder template is not executable Python until substituted and integrated.

Quick Start

Copy the template from assets/template.py and replace placeholders:

• {{ResourceName}} → PascalCase name (e.g., Project)
• {{resource_name}} → snake_case name (e.g., project)
• {{resource_plural}} → plural form (e.g., projects)

Authentication Patterns

# Optional auth - returns None if not authenticated
current_user: Optional[User] = Depends(get_current_user)

# Required auth - raises 401 if not authenticated
current_user: User = Depends(get_current_user_required)

Response Models

@router.get("/items/{item_id}", response_model=Item)
async def get_item(item_id: str) -> Item:
    ...

@router.get("/items", response_model=list[Item])
async def list_items() -> list[Item]:
    ...

HTTP Status Codes

@router.post("/items", status_code=status.HTTP_201_CREATED)
@router.delete("/items/{id}", status_code=status.HTTP_204_NO_CONTENT)

Integration Steps

1. Create router in src/backend/app/routers/

2. Mount in src/backend/app/main.py

3. Create corresponding Pydantic models

4. Create service layer if needed

5. Add frontend API functions
