I'd like replace field type for billing/shipping country, at

Instead of plain CharField I'd like use CountryField from
django_countries.
Is that possible with Mezzanine and how ?
settings.EXTRA_MODEL_FIELDS does not work, it throws an exception same
named field already exists. It sounds logical as it serves for
/extending/ models, not replacing.
I can't also find a setting to specify alternate class for Order model
so it seems subclassing won't be an option.
Any better idea then a fuzzy conversion to/from CountryField in custom
form ?
It's not all that difficult. I've done something similar with a custom
OrderForm class in cartridge-braintree (now maintained by Henri)
https://github.com/henri-hulski/cartridge_braintree/blob/master/cartridge_braintree/forms.py#L77-L83
So basically:
- Create a subclass of OrderForm
- Override the country field widgets
- and in urls.py, use this Order Form as the one used by the shop (pass
form_class=myapp.forms.MyOrderForm, when calling the shop/checkout views)
(Old style would be to use SHOP_CHECKOUT_FORM_CLASS but that's not
recommended for Django 1.8 onwards)
