Hi People!
I have added the following field to order:
(
"cartridge.shop.models.Order.billing_detail_municipality",
"ForeignKey",
("cartridge_chilean_shipping.Municipality",),
{"verbose_name": _("Municipality"), "related_name":
"orders_billing",
},
),
It is displayed correctly in the checkout form, but when I go to the next
step I got:
Traceback:

Exception Type: TypeError at /shop/checkout/
Exception Value: <Municipality: 2101 - Antofagasta (Antofagasta,
Antofagasta)> is not JSON serializable
The problem seems to be because I'm using redis-sessions (because I need
django-ws4redis) and models with FK can't be serialized out of the box.
Without the FK it works like a charm. I have tried to set a custom
serializer for JSON but with no success.
Has someone dealt with this before?
Thanks in advance,
Rodrigo
