Best Practices
✅ DO
- Use models for database operations
- Implement proper indexes on frequently queried fields
- Use select_related and prefetch_related for query optimization
- Implement authentication and permissions
- Use Django Forms for form validation
- Cache expensive queries
- Use management commands for batch operations
- Implement logging for debugging
- Use middleware for cross-cutting concerns
- Validate user input
❌ DON'T
- Use raw SQL without ORM
- N+1 query problems without optimization
- Store secrets in code
- Trust user input directly
- Override init in models unnecessarily
- Make synchronous heavy operations in views
- Use inheritance models unless necessary
- Expose stack traces in production
