About This Skill

Django API Builder is a comprehensive skill for building production-grade REST APIs using Django and Django REST Framework. It handles the full stack from model design through serialization, authentication, and documentation.

Generated Components

Models Generates Django ORM models with proper field types, `__str__` methods, Meta classes, and database indexes for performance-critical queries.

Serializers - `ModelSerializer` classes with explicit field declarations - Nested serializers for related objects - Custom validation methods (`validate_<field>` and `validate`) - Read vs write serializer separation where needed

ViewSets and Routers - `ModelViewSet` or granular `GenericAPIView` subclasses - Permission classes (`IsAuthenticated`, `IsOwner`, custom) - Filtering with `django-filter` - Pagination with cursor or page-number pagination

Authentication - JWT setup via `djangorestframework-simplejwt` - Token refresh and rotation patterns - Custom user model integration

Documentation - Auto-generated OpenAPI 3.0 spec via `drf-spectacular` - Swagger UI and ReDoc endpoints configured

Works with PostgreSQL, SQLite, and MySQL backends.

Use Cases

  • Building RESTful APIs with Django REST Framework
  • Implementing JWT or session-based authentication systems

  • Creating OpenAPI/Swagger documentation for existing APIs
