django

High-level Python framework with batteries included for rapid, secure web development.

Core Concepts

• ORM: queryset API with lazy evaluation, select_related/prefetch_related for N+1 prevention
• Admin interface: auto-generated CRUD from models, customizable via ModelAdmin classes
• Class-based views: ListView, DetailView, CreateView reduce boilerplate over function views
• DRF: ModelViewSet + Serializer classes for RESTful APIs with browsable docs

Common Patterns

• Signals: post_save/pre_delete for decoupled side effects like cache invalidation
• Middleware: request/response pipeline for auth, CORS, logging, or rate limiting
• Auth system: built-in User model, permissions, groups, and session-based authentication
• Testing: TestCase with Client for request simulation, assertContains for template checks

Best Practices

• Use select_related for FK relationships and prefetch_related for M2M to avoid N+1 queries
• Keep business logic in model methods or service layers, not in views or signals
• Apply database-level constraints (unique, FK) alongside model-level validation
• Use @login_required and @permission_required decorators rather than manual checks

Common Code Patterns

• class ArticleView(DetailView): model = Article; template_name = "article.html"
• @api_view(["GET"]) with @permission_classes([IsAuthenticated]) for DRF endpoints
