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
