Project Structure

  • Keep apps small and focused
  • Use apps/ directory for apps
  • Separate settings per environment
  • Use environment variables for secrets

Models

  • Use verbose_name for fields
  • Add indexes for queried fields
  • Use select_related/prefetch_related
  • Avoid N+1 queries
  • Use custom managers for common queries

Views

  • Use class-based views for CRUD
  • Use function views for simple logic
  • Return proper HTTP status codes
  • Use Django REST Framework for APIs

Security

  • Never disable CSRF protection
  • Use Django's ORM (no raw SQL)
  • Validate all inputs
  • Use Django's auth system
  • Keep DEBUG=False in production

Performance
