Error
TypeError at /api/v1/orders/order/create/
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 OrderDetailSerializer.create() method to handle this correctly.
