How to return a json in get_queryset()?

I want to return a error message in JSON format from a get_queryset() if error occurs. Does anyone knows hot to do it?

    def get_queryset(self):
        try:
            #some code that returns a queryset
        except:
            return Response({"status": "ERROR!"})

But obviously I`m unable to do that. Does anyone knows how to resolve this?

One possible way is to somehow convert the message into queryset and return it. But I don`t know how to do it!

I suppose that if you want to return a Response the get_queryset() method is inside a class-based view. As the name says the method itself can only return a QuerySet, though inside a view you can raise certain exceptions which are turned into a response by Django's built-in exception handling.

You can eg. raise an Http404 and Django will automatically respond with 404 response status.

This behaviour you can customize and eg. return a JsonResponse instead of the normal response.
