"detail": "method \delete\ not allowed" django

I made a view that can use put, delete request using modelviewset and mapped it with url. I have clearly made it possible to request put and delete request to url, but if you send delete request to url, I return 405 error. What's wrong with my code? Here's my code.

views.py

class UpdateDeletePostView (ModelViewSet) :
    serializer_class = PostSerializer
    permission_classes = [IsAuthenticated, IsOwner]
    queryset = Post.objects.all()

    def update (self, request, *args, **kwargs) :
        super().update(request, *args, **kwargs)
        return Response({'success': '게시물이 수정 되었습니다.'}, status=200)

    def destroy (self, request, *args, **kwargs) :
        super().destroy(request, *args, **kwargs)
        return Response({'success': '게시물이 삭제 되었습니다.'}, status=200)

feed\urls.py

path('post/<int:pk>', UpdateDeletePostView.as_view({'put': 'update', 'delete': 'destroy'})),

server\urls.py

path('feed/', include('feed.urls')),

and error

"detail": "method \delete\ not allowed"

as I wrote in the comment looks like you don't need a ViewSet because you are handling just operations on a single item. In general you can restrict the operations available for Views or ViewSet using proper mixins.

I suggest two possible approaches

Use Generic View

class UpdateDeletePostView(
        UpdateModelMixin,
        DeleteModelMixin,
        GenericAPIView):
    .....

and

urlpatterns = [
    path('post/<int:pk>', UpdateDeletePostView.as_view()),
    ...
]

Use ViewSet and Router

class UpdateDeletePostViewSet(
        UpdateModelMixin,
        DeleteModelMixin,
        GenericViewset):
    .....

router = SimpleRouter()
router.register('feed', UpdateDeletePostViewSet)

urlpatterns = [
    path('', include(router.urls)),
    ...
]
