How to Return JSON-Encoded Response for non-dict object

An HttpResponse subclass that helps to create a JSON-encoded response. Its default Content-Type header is set to application/JSON.

The first parameter, data, should be a dict instance. If non-dict object is passed as the first argument, a TypeError will be raised.

Example dict instance:

from django.http import JsonResponse

def user(req):
    response = {
        'id': 1,
        'name': 'Tom',
        'status': Active
    return JsonResponse(response)

Example non-dict object:

return JsonResponse([1, 2, 3, 4])

TypeError: In order to allow non-dict objects to be serialized set the safe parameter to False

By default, the JsonResponse’s first parameter, data, should be a dict instance. To pass any other JSON-serializable object you must set the safe parameter to False.

return JsonResponse([1, 2, 3, 4], safe=False)

The safe boolean parameter defaults to True. If it’s set to False, any object can be passed for serialization (otherwise only dict instances are allowed).
