Disable a method in a ViewSet, django-rest-framework

In Django REST framework, you can disable specific methods in a ViewSet by using the @action decorator and specifying the detail parameter appropriately. This allows you to customize which HTTP methods are allowed for a particular action.

Here's how you can disable a method in a ViewSet using the @action decorator:

Assuming you have a ViewSet named MyViewSet and you want to disable the create method:

from rest_framework.decorators import action from rest_framework.response import Response from rest_framework import viewsets class MyViewSet(viewsets.ViewSet): # Your viewset implementation here @action(detail=False, methods=['GET', 'PUT', 'PATCH', 'DELETE']) def create(self, request): return Response({'detail': 'Method not allowed.'}, status=405)

In this example, the @action decorator is used to create a custom action named create that responds to GET, PUT, PATCH, and DELETE methods. The detail=False parameter specifies that this action is not related to a specific instance (object). Inside the action method, a custom response is returned with a 405 Method Not Allowed status code, indicating that the method is disabled.

Keep in mind that this approach provides more flexibility compared to directly modifying the allowed HTTP methods on a standard action provided by the ViewSet methods (list, retrieve, create, update, partial_update, destroy).

Remember to adjust the methods parameter and the custom response message according to your needs.
