Is it possible to custom views or models like oscar_fork_app in django-oscar?

[joyzhang15]

I was wondering if there is a way that I can custom views or models in django-oscar-accounts? Just like oscar_fork_app command in django-oscar.

It seems like it should work, as https://github.com/django-oscar/django-oscar-accounts/blob/master/src/oscar_accounts/models.py uses if not is_model_registered('oscar_accounts', 'AccountType'): sequences like django-oscar models.

I tried it on Oscar 2.0.x and Django 2.2, and it fails.

When I modify INSTALLED_APPS to replace 'oscar_accounts' with 'custom_oscar_apps.oscar_accounts'

Traceback (most recent call last):

    "INSTALLED_APPS." % (module, name)
RuntimeError: Model class oscar_accounts.models.AccountType doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

However if I modify models.py to define all of the models from oscar_accounts, I get further.

e.g. custom_oscar_apps/oscar_accounts/models.py

from oscar_accounts import abstract_models


class AccountType(abstract_models.AccountType):
    pass


class Account(abstract_models.Account):
    pass


class Transfer(abstract_models.Transfer):
    pass


class Transaction(abstract_models.Transaction):
    pass


class IPAddressRecord(abstract_models.IPAddressRecord):
    pass

After that, and forking accounts_dashboard, it looks like I have a working fork.

@jayvdb I'am looking for some solution for forking oscar_accounts, but nothing work for me, not even your solution. Do you have any update on this or someone else does? Thx

Also looking for a solution here. I see the models are dynamically loaded using oscar's get_model. So it seems like I should be able to override them. No luck yet.
