Common Mistakes

Using 'include' as a string in the path.

from rest_framework.response import Response

class BookViewSet(ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookSerializer

    @[1](methods=['[2]'], detail=[3])
    def recent(self, request):
        recent_books = Book.objects.order_by('-published_date')[:5]
        serializer = self.get_serializer(recent_books, many=True)
        return Response(serializer.data)

💡 Hint

Common Mistakes

Using 'post' instead of 'get' for the method.

Setting detail to True when it should be False.

Forgetting to import 'action'.

The @action decorator creates a custom route. It should respond to GET requests and be a list route (False).
