    list_display_links = ('id', 'user')
    list_filter = ('user', )
    list_per_page = 20

admin.site.register(Profile, ProfileAdmin)

这里我使用 AbstractBaseUser 扩展用户模型。我想添加一个新的配置文件。我正在使用 OneToOneField 添加带有 CustomUser 模型的配置文件模型。我的注册和登录有效。但是看不到配置文件并且会出错但是我遇到了上面的问题请帮帮我！！

Answer 1

已解决。

我在 signals.py 中遇到 Profile.objects.create 的问题它是从 apps.py 导入的。在 settings.py 已安装的应用程序中，我直接包含了我的 appname。通过写 'users'。将用户更改为 'users.apps.UsersConfig' 解决了错误。
