Model documentation is confusing...

[monokrome]

The documentation from 566fe67 is super confusing, because it refers to the setting as OAUTH2_PROVIDER_APPLICATION_MODEL but later refers to it as APPLICATION_MODEL.

Is this two settings? Is it one setting, and - if so - which name is it? I think that it's intended to be a single setting called APPLICATION_MODEL, but not 100% sure.

EDIT: It actually looks like you need to set both settings or else it won't work, even though they have the same values

OAUTH2_PROVIDER_APPLICATION_MODEL field should be used in your django project setting file which is later assigned to APPLICATION_MODEL field of oauth2_provider settings module.

What you can do in swapped model is reference OAUTH2_PROVIDER_APPLICATION_MODEL from your django project settings.

from django.conf import settings
from django.db import models

class Grant(AbstractGrant):
    application = models.ForeignKey(settings.OAUTH2_PROVIDER_APPLICATION_MODEL, related_name='grants', on_delete=models.CASCADE)
