Django Rest中的DELETE方法

Question

I am trying to DELETE record in Django Rest.

views.py :-

class ItemPartialView(generics.RetrieveUpdateDestroyAPIView):

    queryset = itemlist.objects.all()
    serializer_class = ItemlistSerializer

    def put(self, request, *args, **kwargs):
        return self.partial_update(request, *args, **kwargs)

    def destroy(self, request, *args, **kwargs):
        obj = self.get_object()
        if obj.survey:
            return Response(data={'message': "Too late to delete"},
                        status=status.HTTP_400_BAD_REQUEST)
        self.perform_destroy(obj)
        return Response(status=status.HTTP_204_NO_CONTENT)

urls.py :-

urlpatterns = {
    url(r'^itemlists/$', ItemView.as_view(), name="create"),
    url(r'^itemlists/(?P<pk>\d+)/$', ItemPartialUpdateView.as_view(), name="update")

}

Now, when I am sending DELETE request to itemlists/1/ , it is not deleting the record with id = 1 Error is showing Method DELETE not allowed

(CREATE, READ, UPDATE are working except DELETE, so I don't think it's cors related issue).

Answer 1

You seem to have 2 routes defined for itemlists/1/ . Your code is hitting the first one which only has partial update (PUT/PATCH) support judging from the name.

You should create one view with both update and destroy on the same class. That should work.

Answer 2

As I see it - you don't use your ItemPartialView in your urls.

You use ItemPartialUpdateView instead, so my guess is that delete is not supported with this view.
