Django REST Framework - RetrieveAPIView

DRF tip:

RetrieveAPIView is similar to the ListAPIView -- it's used for read-only endpoints and only accepts GET requests, but it returns a single instance instead of a list. It extends RetrieveModelMixin.

class PostDetail(generics.RetrieveAPIView):
    serializer_class = PostSerializer
    queryset = Post.objects.all()
