Implement CRUD API endpoints for todo management
- Add comprehensive todo endpoints in app/api/endpoints/todos.py with full CRUD operations
- Create API router organization in app/api/api.py
- Integrate API routes with main FastAPI app using /api/v1 prefix
- Include proper HTTP status codes, error handling, and REST conventions
- Add proper package initialization files for all modules
- Clean up temporary validation and migration files
- Update README with current project structure
API endpoints available:
- GET /api/v1/todos - list all todos
- POST /api/v1/todos - create new todo
- GET /api/v1/todos/{id} - get specific todo
- PUT /api/v1/todos/{id} - update todo
- DELETE /api/v1/todos/{id} - delete todo

The application uses SQLite database stored at `/app/storage/db/db.sqlite`. Database migrations are managed with Alembic.
|
||||
|
||||
### Database Migrations
|
||||
|
||||
To run database migrations:
|
||||
|
||||
```bash
|
||||
# Upgrade to latest migration
|
||||
alembic upgrade head
|
||||
|
||||
# Check current migration status
|
||||
alembic current
|
||||
|
||||
# Create a new migration (after modifying models)
|
||||
alembic revision --autogenerate -m "Description of changes"
|
||||
|
||||
# Downgrade by one migration
|
||||
alembic downgrade -1
|
||||
```
|
||||
|
||||
The initial migration creates the `todos` table with the following structure:
|
||||
- `id` (Integer, Primary Key)
|
||||
- `title` (String, Required)
|
||||
- `description` (Text, Optional)
|
||||
- `completed` (Boolean, Default: False)
|
||||
- `created_at` (DateTime, Auto-generated)
|
||||
- `updated_at` (DateTime, Auto-updated)
|
||||
|
||||
## Environment Variables

||||

||||
Currently, no environment variables are required for basic operation.
