Пользовательские (заменяемые) модели для Django OAuth Toolkit

Question

Мне нужно создать собственные модели Django OAuth Toolkit. У меня есть приложение с этими моделями:

from django.utils.translation import ugettext_lazy as _
from oauth2_provider.models import (
    AbstractApplication, AbstractGrant,
    AbstractAccessToken, AbstractRefreshToken
)


class Application(AbstractApplication):
    GRANT_TYPES = (
        (AbstractApplication.GRANT_AUTHORIZATION_CODE, _("Authorization code")),
        (AbstractApplication.GRANT_IMPLICIT, _("Implicit")),
    )


class Grant(AbstractGrant):
    pass


class AccessToken(AbstractAccessToken):
    pass


class RefreshToken(AbstractRefreshToken):
    pass

И настройки:

INSTALLED_APPS = [
    ...
    'oauth2_provider',
    ...
    'apps.oauth.apps.OauthConfig',
    ...
]

OAUTH2_PROVIDER_GRANT_MODEL = 'oauth.Grant'
OAUTH2_PROVIDER_APPLICATION_MODEL = 'oauth.Application'
OAUTH2_PROVIDER_ACCESS_TOKEN_MODEL = 'oauth.AccessToken'
OAUTH2_PROVIDER_REFRESH_TOKEN_MODEL = 'oauth.RefreshToken'

И когда я пытаюсь выполнить миграцию, я получаю эту ошибку:

ValueError: The field oauth2_provider.AccessToken.application was declared with a lazy reference to 'oauth.application', but app 'oauth' isn't installed.
The field oauth2_provider.AccessToken.source_refresh_token was declared with a lazy reference to 'oauth.refreshtoken', but app 'oauth' isn't installed.
The field oauth2_provider.Grant.application was declared with a lazy reference to 'oauth.application', but app 'oauth' isn't installed.
The field oauth2_provider.RefreshToken.access_token was declared with a lazy reference to 'oauth.accesstoken', but app 'oauth' isn't installed.
The field oauth2_provider.RefreshToken.application was declared with a lazy reference to 'oauth.application', but app 'oauth' isn't installed.

Если я удаляю настройки OAUTH2_PROVIDER_***_MODEL и снова запускаю makemigrations, я получаю много ошибок fields.E304 и fields.E305:

Мы с друзьями сделали следующее: Чтобы переопределить классы, используемые Django OAuth Toolkit, Нет таких настроек, как миграция и миграция:

OAUTH2_PROVIDER_APPLICATION_MODEL = 'oauth2_provider.Application'
OAUTH2_PROVIDER_REFRESH_TOKEN_MODEL = 'oauth2_provider.RefreshToken'

После запуска миграции удалите или прокомментируйте переменные, упомянутые выше, и поместите переменные ссылаясь на классы, которые нужно было перезаписать, в нашем случае это было так:

OAUTH2_PROVIDER_APPLICATION_MODEL = 'authentication.OAuthApplication'
OAUTH2_PROVIDER_GRANT_MODEL = 'authentication.OAuthGrant'
OAUTH2_PROVIDER_ACCESS_TOKEN_MODEL = 'authentication.OAuthAccessToken'
OAUTH2_PROVIDER_REFRESH_TOKEN_MODEL = 'authentication.OAuthRefreshToken'

В этой ссылке https://django -oauth-toolkit.readthedocs.io / en / latest / advanced_topics.html # extending-the-application-model содержит подробную информацию о том, зачем вам нужен этот процесс .
