## Technical Highlights
|
||||||
|
|
||||||
|
### Python Version Compatibility
|
||||||
|
|
||||||
|
- **Issue**: SQLAlchemy 2.0.23 incompatible with Python 3.13
|
||||||
|
- **Solution**: Upgraded to SQLAlchemy 2.0.44
|
||||||
|
- **Result**: All tests passing on Python 3.13.7
|
||||||
|
|
||||||
|
### Async Support
|
||||||
|
|
||||||
|
- Uses aiosqlite for async SQLite operations
|
||||||
|
- AsyncSession for non-blocking database operations
|
||||||
|
- Proper async context managers for session lifecycle
|
||||||
|
|
||||||
|
### SQLite Optimizations
|
||||||
|
|
||||||
|
- WAL (Write-Ahead Logging) mode enabled
|
||||||
|
- Foreign key constraints enabled via PRAGMA
|
||||||
|
- Static pool for single-connection use
|
||||||
|
- Automatic conversion of sqlite:/// to sqlite+aiosqlite:///
|
||||||
|
|
||||||
|
### Type Safety
|
||||||
|
|
||||||
|
- Comprehensive type hints using SQLAlchemy 2.0 Mapped types
|
||||||
|
- Pydantic integration for validation
|
||||||
|
- Type-safe relationships and foreign keys
|
||||||
|
|
||||||
|
## Integration Points
|
||||||
|
|
||||||
|
### FastAPI Endpoints
|
||||||
|
|
||||||
|
```python
|
||||||
|
@app.get("/anime")
|
||||||
|
async def get_anime(db: AsyncSession = Depends(get_database_session)):
|
||||||
|
result = await db.execute(select(AnimeSeries))
|
||||||
|
return result.scalars().all()
|
||||||
|
```
|
||||||
|
|
||||||
|
### Service Layer

|
|
||||||
|
### Database Connection Management
|
||||||
|
|
||||||
|
#### Initialization
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.server.database import init_db, close_db
|
||||||
|
|
||||||
|
# Application startup
|
||||||
|
await init_db() # Creates engine, session factory, and tables
|
||||||
|
|
||||||
|
# Application shutdown
|
||||||
|
await close_db() # Closes connections and cleanup
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Session Management
|
||||||
|
|
||||||
|
**Async Sessions** (preferred for FastAPI endpoints):
|
||||||
|
|
||||||
|
```python
|
||||||
|
from fastapi import Depends
|
||||||
|
from sqlalchemy.ext.asyncio import AsyncSession
|
||||||
|
from src.server.database import get_db_session
|
||||||
|
|
||||||
|
@app.get("/anime")
|
||||||
|
async def get_anime(db: AsyncSession = Depends(get_db_session)):
|
||||||
|
result = await db.execute(select(AnimeSeries))
|
||||||
|
return result.scalars().all()
|
||||||
|
```
|
||||||
|
|
||||||
|
**Sync Sessions** (for non-async operations):
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.server.database.connection import get_sync_session
|
||||||
|
|
||||||
|
session = get_sync_session()
|
||||||
|
try:
|
||||||
|
result = session.execute(select(AnimeSeries))
|
||||||
|
return result.scalars().all()
|
||||||
|
finally:
|
||||||
|
session.close()
|
||||||
|
```
|
||||||
|
|
||||||
|
### Database Configuration
|
||||||
|
|
||||||
|
**Settings** (from `src/config/settings.py`):
|
||||||
|
|
||||||
|
- `DATABASE_URL`: Database connection string
|
||||||
|
- Default: `sqlite:///./data/aniworld.db`
|
||||||
|
- Automatically converted to `sqlite+aiosqlite:///` for async support
|
||||||
|
- `LOG_LEVEL`: When set to "DEBUG", enables SQL query logging
|
||||||
|
|
||||||
|
**Engine Configuration**:
|
||||||
|
|
||||||
|
- **SQLite**: Uses StaticPool, enables foreign keys and WAL mode
|
||||||
|
- **PostgreSQL/MySQL**: Uses QueuePool with pre-ping health checks
|
||||||
|
- **Connection Pooling**: Configured based on database type
|
||||||
|
- **Echo**: SQL query logging in DEBUG mode
|
||||||
|
|
||||||
|
### SQLite Optimizations
|
||||||
|
|
||||||
|
- **Foreign Keys**: Automatically enabled via PRAGMA
|
||||||
|
- **WAL Mode**: Write-Ahead Logging for better concurrency
|
||||||
|
- **Static Pool**: Single connection pool for SQLite
|
||||||
|
- **Async Support**: aiosqlite driver for async operations
|
||||||
|
|
||||||
|
### FastAPI Integration
|
||||||
|
|
||||||
|
**Dependency Injection** (in `src/server/utils/dependencies.py`):
|
||||||
|
|
||||||
|
```python
|
||||||
|
async def get_database_session() -> AsyncGenerator:
|
||||||
|
"""Dependency to get database session."""
|
||||||
|
try:
|
||||||
|
from src.server.database import get_db_session
|
||||||
|
|
||||||
|
async with get_db_session() as session:
|
||||||
|
yield session
|
||||||
|
except ImportError:
|
||||||
|
raise HTTPException(status_code=501, detail="Database not installed")
|
||||||
|
except RuntimeError as e:
|
||||||
|
raise HTTPException(status_code=503, detail=f"Database not available: {str(e)}")
|
||||||
|
```
|
||||||
|
|
||||||
|
**Usage in Endpoints**:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from fastapi import Depends
|
||||||
|
from sqlalchemy.ext.asyncio import AsyncSession
|
||||||
|
from src.server.utils.dependencies import get_database_session
|
||||||
|
|
||||||
|
@router.get("/series/{series_id}")
|
||||||
|
async def get_series(
|
||||||
|
series_id: int,
|
||||||
|
db: AsyncSession = Depends(get_database_session)
|
||||||
|
):
|
||||||
|
result = await db.execute(
|
||||||
|
select(AnimeSeries).where(AnimeSeries.id == series_id)
|
||||||
|
)
|
||||||
|
series = result.scalar_one_or_none()
|
||||||
|
if not series:
|
||||||
|
raise HTTPException(status_code=404, detail="Series not found")
|
||||||
|
return series
|
||||||
|
```
|
||||||
|
|
||||||
|
### Testing
|
||||||
|
|
||||||
|
**Test Suite**: `tests/unit/test_database_models.py`
|
||||||
|
|
||||||
|
**Coverage**:
|
||||||
|
|
||||||
|
- 30+ comprehensive test cases
|
||||||
|
- Model creation and validation
|
||||||
|
- Relationship testing (one-to-many, cascade deletes)
|
||||||
|
- Unique constraint validation
|
||||||
|
- Query operations (filtering, joins)
|
||||||
|
- Session management
|
||||||
|
- Mixin functionality
|
||||||
|
|
||||||
|
**Test Strategy**:
|
||||||
|
|
||||||
|
- In-memory SQLite database for isolation
|
||||||
|
- Fixtures for engine and session setup
|
||||||
|
- Test all CRUD operations
|
||||||
|
- Verify constraints and relationships
|
||||||
|
- Test edge cases and error conditions
|
||||||
|
|
||||||
|
### Migration Strategy (Future)
|
||||||
|
|
||||||
|
**Alembic Integration** (planned):
|
||||||
|
|
||||||
|
- Alembic installed but not yet configured
|
||||||
|
- Will manage schema migrations in production
|
||||||
|
- Auto-generate migrations from model changes
|
||||||
|
- Version control for database schema
|
||||||
|
|
||||||
|
**Initial Setup**:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize Alembic (future)
|
||||||
|
alembic init alembic
|
||||||
|
|
||||||
|
# Generate initial migration
|
||||||
|
alembic revision --autogenerate -m "Initial schema"
|
||||||
|
|
||||||
|
# Apply migrations
|
||||||
|
alembic upgrade head
|
||||||
|
```
|
||||||
|
|
||||||
|
### Production Considerations
|
||||||
|
|
||||||
|
**Single-Process Deployment** (current):
|
||||||
|
|
||||||
|
- SQLite with WAL mode for concurrency
|
||||||
|
- Static pool for single connection
|
||||||
|
- File-based storage at `data/aniworld.db`
|
||||||
|
|
||||||
|
**Multi-Process Deployment** (future):
|
||||||
|
|
||||||
|
- Switch to PostgreSQL or MySQL
|
||||||
|
- Configure connection pooling (pool_size, max_overflow)
|
||||||
|
- Use QueuePool for connection management
|
||||||
|
- Consider read replicas for scaling
|
||||||
|
|
||||||
|
**Performance**:
|
||||||
|
|
||||||
|
- Indexes on frequently queried columns (key, name, status, is_active)
|
||||||
|
- Foreign key constraints for referential integrity
|
||||||
|
- Cascade deletes for cleanup operations
|
||||||
|
- Efficient joins via relationship loading strategies
|
||||||
|
|
||||||
|
**Monitoring**:
|
||||||
|
|
||||||
|
- SQL query logging in DEBUG mode
|
||||||
|
- Connection pool metrics (when using QueuePool)
|
||||||
|
- Query performance profiling
|
||||||
|
- Database size monitoring
|
||||||
|
|
||||||
|
**Backup Strategy**:
|
||||||
|
|
||||||
|
- SQLite: File-based backups (copy `aniworld.db` file)
|
||||||
|
- WAL checkpoint before backup
|
||||||
|
- Automated backup schedule recommended
|
||||||
|
- Store backups in `data/config_backups/` or separate location
|
||||||
|
|
||||||
|
### Integration with Services
|
||||||
|
|
||||||
|
**AnimeService**:
|
||||||
|
|
||||||
|
- Query series from database
|
||||||
|
- Persist scan results
|
||||||
|
- Update episode metadata
|
||||||
|
|
||||||
|
**DownloadService**:
|
||||||
|
|
||||||
|
- Load queue from database on startup
|
||||||
|
- Persist queue state continuously
|
||||||
|
- Update download progress in real-time
|
||||||
|
|
||||||
|
**AuthService**:
|
||||||
|
|
||||||
|
- Store and validate user sessions
|
||||||
|
- Session revocation via database
|
||||||
|
- Query active sessions for monitoring
|
||||||
|
|
||||||
|
### Benefits of Database Layer

# Database Layer
|
||||||
|
|
||||||
|
SQLAlchemy-based database layer for the Aniworld web application.
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
This package provides persistent storage for anime series, episodes, download queue, and user sessions using SQLAlchemy ORM.
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### Installation
|
||||||
|
|
||||||
|
Install required dependencies:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install sqlalchemy alembic aiosqlite
|
||||||
|
```
|
||||||
|
|
||||||
|
Or use the project requirements:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install -r requirements.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
### Initialization
|
||||||
|
|
||||||
|
Initialize the database on application startup:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.server.database import init_db, close_db
|
||||||
|
|
||||||
|
# Startup
|
||||||
|
await init_db()
|
||||||
|
|
||||||
|
# Shutdown
|
||||||
|
await close_db()
|
||||||
|
```
|
||||||
|
|
||||||
|
### Usage in FastAPI
|
||||||
|
|
||||||
|
Use the database session dependency in your endpoints:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from fastapi import Depends
|
||||||
|
from sqlalchemy.ext.asyncio import AsyncSession
|
||||||
|
from src.server.database import get_db_session, AnimeSeries
|
||||||
|
from sqlalchemy import select
|
||||||
|
|
||||||
|
@app.get("/anime")
|
||||||
|
async def get_anime(db: AsyncSession = Depends(get_db_session)):
|
||||||
|
result = await db.execute(select(AnimeSeries))
|
||||||
|
return result.scalars().all()
|
||||||

|
### UserSession
|
||||||
|
|
||||||
|
User authentication sessions.
|
||||||
|
|
||||||
|
```python
|
||||||
|
from datetime import datetime, timedelta

|
||||||
|
is_active=True
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Mixins
|
||||||
|
|
||||||
|
### TimestampMixin
|
||||||
|
|
||||||
|
Adds automatic timestamp tracking:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.server.database.base import Base, TimestampMixin
|
||||||
|
|
||||||
|
class MyModel(Base, TimestampMixin):
|
||||||
|
__tablename__ = "my_table"
|
||||||
|
# created_at and updated_at automatically added
|
||||||
|
```
|
||||||
|
|
||||||
|
### SoftDeleteMixin
|
||||||
|
|
||||||
|
Provides soft delete functionality:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.server.database.base import Base, SoftDeleteMixin
|
||||||
|
|
||||||
|
class MyModel(Base, SoftDeleteMixin):
|
||||||
|
__tablename__ = "my_table"
|
||||||
|
|
||||||
|
# Usage
|
||||||
|
instance.soft_delete() # Mark as deleted
|
||||||
|
instance.is_deleted # Check if deleted
|
||||||
|
instance.restore() # Restore deleted record
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Configure database via environment variables:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
DATABASE_URL=sqlite:///./data/aniworld.db
|
||||||
|
LOG_LEVEL=DEBUG # Enables SQL query logging
|
||||||
|
```
|
||||||
|
|
||||||
|
Or in code:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from src.config.settings import settings
|
||||||
|
|
||||||
|
settings.database_url = "sqlite:///./data/aniworld.db"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Migrations (Future)
|
||||||
|
|
||||||
|
Alembic is installed for database migrations:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Initialize Alembic
|
||||||
|
alembic init alembic
|
||||||
|
|
||||||
|
# Generate migration
|
||||||
|
alembic revision --autogenerate -m "Description"
|
||||||
|
|
||||||
|
# Apply migrations
|
||||||
|
alembic upgrade head
|
||||||
|
|
||||||
|
# Rollback
|
||||||
|
alembic downgrade -1
|
||||||
|
```
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
Run database tests:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pytest tests/unit/test_database_models.py -v
|
||||||
|
```
|
||||||
|
|
||||||
|
The test suite uses an in-memory SQLite database for isolation and speed.
|
||||||
|
|
||||||
|
## Architecture
|
||||||
|
|
||||||
|
- **base.py**: Base declarative class and mixins
|
||||||
|
- **models.py**: SQLAlchemy ORM models (4 models)
|
||||||
|
- **connection.py**: Engine, session factory, dependency injection
|
||||||
|
- **migrations.py**: Alembic migration placeholder
|
||||||
|
- ****init**.py**: Package exports
|
||||||
|
|
||||||
|
## Database Schema
|
||||||
|
|
||||||
|
```
|
||||||
|
anime_series (id, key, name, site, folder, ...)
|
||||||
|
├── episodes (id, series_id, season, episode_number, ...)
|
||||||
|
└── download_queue (id, series_id, season, episode_number, status, ...)
|
||||||
|
|
||||||
|
user_sessions (id, session_id, token_hash, expires_at, ...)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Production Considerations
|
||||||
|
|
||||||
|
### SQLite (Current)
|
||||||
|
|
||||||
|
- Single file: `data/aniworld.db`
|
||||||
|
- WAL mode for concurrency
|
||||||
|
- Foreign keys enabled
|
||||||
|
- Static connection pool
|
||||||
|
|
||||||
|
### PostgreSQL/MySQL (Future)
|
||||||
|
|
||||||
|
For multi-process deployments:
|
||||||
|
|
||||||
|
```python
|
||||||
|
DATABASE_URL=postgresql+asyncpg://user:pass@host/db
|
||||||
|
# or
|
||||||
|
DATABASE_URL=mysql+aiomysql://user:pass@host/db
|
||||||
|
```
|
||||||
|
|
||||||
|
Configure connection pooling:
|
||||||
|
|
||||||
|
```python
|
||||||
|
engine = create_async_engine(
|
||||||
|
url,
|
||||||
|
pool_size=10,
|
||||||
|
max_overflow=20,
|
||||||
|
pool_pre_ping=True
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performance Tips
|
||||||
|
|
||||||
|
1. **Indexes**: Models have indexes on frequently queried columns
|
||||||
|
2. **Relationships**: Use `selectinload()` or `joinedload()` for eager loading
|
||||||
|
3. **Batching**: Use bulk operations for multiple inserts/updates
|
||||||
|
4. **Query Optimization**: Profile slow queries in DEBUG mode
|
||||||
|
|
||||||
|
Example with eager loading:
|
||||||
|
|
||||||
|
```python
|
||||||
|
from sqlalchemy.orm import selectinload
|
||||||
|
|
||||||
|
result = await db.execute(
|
||||||
|
select(AnimeSeries)
|
||||||
|
.options(selectinload(AnimeSeries.episodes))
|
||||||
|
.where(AnimeSeries.key == "attack-on-titan")
|
||||||
|
)
|
||||||
|
series = result.scalar_one()
|
||||||
|
# episodes already loaded, no additional queries
|
||||||
|
```
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Database not initialized
|
||||||
|
|
||||||
|
```
|
||||||
|
RuntimeError: Database not initialized. Call init_db() first.
|
||||||
|
```
|
||||||
|
|
||||||
|
Solution: Call `await init_db()` during application startup.
|
||||||
|
|
||||||
|
### Table does not exist
|
||||||
|
|
||||||
|
```
|
||||||
|
sqlalchemy.exc.OperationalError: no such table: anime_series
|
||||||
|
```
|
||||||
|
|
||||||
|
Solution: `Base.metadata.create_all()` is called automatically by `init_db()`.
|
||||||
|
|
||||||
|
### Foreign key constraint failed
|
||||||
|
|
||||||
|
```
|
||||||
|
sqlalchemy.exc.IntegrityError: FOREIGN KEY constraint failed
|
||||||
|
```
|
||||||
|
|
||||||
|
Solution: Ensure referenced records exist before creating relationships.
