CLAUDE.md — Django

Commands

  • python manage.py runserver — dev server
  • python manage.py test — run tests
  • python manage.py makemigrations — create migrations
  • python manage.py migrate — apply migrations
  • python manage.py shell_plus — enhanced shell

Code Style

  • Follow Django conventions (fat models, thin views)
  • Use class-based views for CRUD, function-based for custom logic
  • Use Django REST Framework serializers for API validation
  • Use select_related/prefetch_related to avoid N+1 queries
  • Use Django signals sparingly — prefer explicit calls

Architecture

  • apps/ — Django apps (each is a bounded context)
  • core/ — shared utilities, base models, middleware
  • api/ — DRF viewsets and serializers
  • tasks/ — Celery tasks

Database

  • Always create migrations (never modify the database directly)
  • Use Django's ORM — no raw SQL unless performance-critical
  • Index foreign keys and frequently filtered fields
  • Use transactions for multi-model operations
