TypeError at /api/v1/users/3/orders
Got a `TypeError` when calling `Order.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `Order.objects.create()`. You may need to make the field read-only, or override the OrderSerializer.create() method to handle this correctly.
Original exception was:

You\'re seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard page generated by the handler for this status code.
