# Django REST Framework ViewSets & ModelSerializers

Implements Django REST Framework (DRF): ModelViewSet, DefaultRouter, ModelSerializer with validate_<field>, permission classes (IsAuthenticated, IsAdminUser), pagination classes, and filter backends.

## When to Invoke
Invoke this skill whenever you need to:
- create drf modelviewset
- drf defaultrouter urls
- custom serializer validation drf

## Execution SOP & Rules
1. Define serializer: class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product; fields = '__all__'.
2. Define viewset: class ProductViewSet(viewsets.ModelViewSet): queryset = Product.objects.all(); serializer_class = ProductSerializer.
3. Register router: router = DefaultRouter(); router.register(r'products', ProductViewSet); urlpatterns = router.urls.
4. Apply permissions: permission_classes = [IsAuthenticatedOrReadOnly].

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
