To fix Django object is not JSON serializable with Python Django, we can serialize the object with Django’s built in serializers.
For instance, we write
data = serializers.serialize('json', self.get_queryset())
return HttpResponse(data, content_type="application/json")
to call serializers.serialize with 'json' and a query set to serialize the queryset into JSON.
And then we create a HttpResponse object with the serialized data and return that as the response in our view function.
