DRF Viewsets and Router Configuration Scenario

from rest_framework import viewsets, routers
from rest_framework.decorators import action
from rest_framework.response import Response
from django.urls import path, include
from .views import ProductViewSet

class ProductViewSet(viewsets.ModelViewSet):
    queryset = Product.objects.all()
    serializer_class = ProductSerializer
    
    @action(detail=True, methods=['post'])
    def set_featured(self, request, pk=None):
        product = self.get_object()
        product.is_featured = True
        product.save()
        return Response({'status': 'product marked as featured'})

router = routers.DefaultRouter()
router.register(r'products', ProductViewSet)

urlpatterns = [
    path('api/', include(router.urls)),
]
  1. The endpoint for marking a product as featured will be accessible at `/api/products/{id}/set_featured/` with a POST request.

  2. The endpoint will be at `/api/products/set_featured/` without requiring an ID because @action is applied to the viewset class.

  3. The DefaultRouter will not register the custom action because it only handles standard CRUD operations.

  4. The code requires explicit URL definition for the custom action; DefaultRouter cannot automatically handle @action decorators.

Show answer & explanation

Correct answer

The endpoint for marking a product as featured will be accessible at `/api/products/{id}/set_featured/` with a POST request.

Explanation

DefaultRouter automatically generates CRUD endpoints for ViewSet, and @action decorator creates custom endpoints accessible via /products/{id}/set_featured/.
