How to change status of JsonResponse in Django

Question

My API is returning a JSON object on error but the status code is HTTP 200:

response = JsonResponse({\'status

This answer from Sayse works but it's undocumented. If you look at the source you find that it passes the remaining **kwargs to the superclass constructor, HttpStatus. However in the docstring they don't mention that. I don't know if it's the convention to assume that keyword args will be passed to the superclass constructor.

You can also use it like this:

JsonResponse({"error": "not found"}, status=404)

I made a wrapper:

from django.http.response import JsonResponse

class JsonResponseWithStatus(JsonResponse):
    """
    A JSON response object with the status as the second argument.

    JsonResponse passes remaining keyword arguments to the constructor of the superclass,
    HttpResponse. It isn't in the docstring but can be seen by looking at the Django
    source.
    """
    def __init__(self, data, status=None, encoder=DjangoJSONEncoder,
                 safe=True, json_dumps_params=None, **kwargs):
        super().__init__(data, encoder, safe, json_dumps_params, status=status, **kwargs)
