Override serializer delete method in Django RF

I have a serializer that inherits from the django rest framework serializer ModelSerializer.

To overwrite the create method, I can redefine create. To redefine the update method, I redefine update. I'm looking through the code though and can't find the method to overwrite for deletion. I need to do this in the serializer so I can grab the deleting user.

Any thoughts would be appreciated!

I think you can do that but in the view level.

So if you're using ModelViewsets you can override the destory method or the perform_destroy and add your business logic.

    def perform_destroy(self, instance):
        # custom code, pre deletion
        super().perform_destroy(instance)
        # custom code, post deletion

If you're using a ModelViewSet, you could do it in the view:

class YourViewSetClass(ModelViewSet):

    def destroy(self, request, *args, **kwargs):
       user = request.user # deleting user
       # you custom logic # 
       return super(YourViewSetClass, self).destroy(request, *args, **kwargs)

The destroy method is so simple (just a call to instance.delete()) that the action is not delegated to the serializer. The serializers in DRF are for negotiating external representations to/from your database models. Here you simply want to delete a model.
