我试图使用此链接扩展OAuth2应用程序模型。
，但是我在迁移时会出现一些问题 -
value error：oauth2_provider.accesstoken.application字段 懒惰地提到 'oauth2.companyfieldaddedapplication'，但App'oauth2'不是 安装。声明了字段OAuth2_provider.grant.prant.Application 懒惰地提到'oauth2.companyfieldaddedapplication'，但 未安装应用程序" OAuth2"。场 oauth2_provider.refreshtoken. application被懒惰 引用" oauth2.com" 未安装。
我在installed_apps中添加了oauth2，它仍在给出错误
settings.py
installed_apps = [
'apps.oauth2',
]
OAUTH2_PROVIDER_APPLICATION_MODEL='oauth2.CompanyFieldAddedApplication'

尝试将 'oauth2'添加到installed_apps
只需从apps文件夹中删除您的应用程序，然后将其放在外面即可。然后在您的INSTALLED_APPS中添加以下行。
installed_apps = [
'oauth2.apps.Oauth2Config',
]
Oauth2Config是apps.py中的class

i通过将所有表放在数据库中并迁移来解决问题。我不确定为什么它有效，但确实如此。希望我可以帮助别人。
