Django - PUT endpoint authenticator error "wrapped_view() missing 1 required positional argumen-CodePudding

So I'm trying to create a PUT endpoint for editing post data. In the endpoint the post id is given in the URL then the new post dated is inserted into the entity. The issue I'm running into is that request isn't coming through on the authenticator (I'm using Cognito to authenticate, not super important for the error). So even though you can see I'm clearly passing in data, the request isn't coming through on the wrapped_view in the cognito_authenticator function. Why is this happening? The error I'm getting is:

"wrapped_view() missing 1 required positional argument: 'request'"

Test.py

def test_edit(self):
    response = self.client.put(reverse('edit_post_by_id', kwargs={'post_id': str(self.post.uuid)}),
                               data={'body': 'updated text #update'},
                               content_type='application/json',
                               **{'HTTP_AUTHORIZATION': f'bearer {self.cognito.access_token}'})
    self.assertEqual(response.status_code, status.HTTP_200_OK)

View.py

@api_view(['PUT'])
@method_decorator(cognito_authenticator)

def edit_post(request, post_id):
    try:
        post = Post.objects.get(pk=post_id)
    except Post.DoesNotExist:
        return JsonResponse(dict(error=f'Post id: {post_id} does not exists'), status=status.HTTP_400_BAD_REQUEST)

        else:
            # Proceed with the view if valid
            return view_func(request, *args, **kwargs)

CodePudding user response：

With function-based views, you don't need to use method_decorator so:

@api_view(['PUT'])
@cognito_authenticator
def edit_post(request, post_id):
    ...
