Question

迁移我的django和userena包之后

Django 1.8到Django 1.9.7

django-userena 1.4.1 to django-userena == 2.0.1

运行项目后，我收到此错误

我猜python应用程序有一些变化。但是我找不到原因......有没有人帮忙解决这个问题？

提前致谢！

Answer 1

这个问题通常有两个原因。

当安装的应用程序中的依赖关系顺序颠倒时。
如果您还没有在已安装的应用中提及相关性。

在这种情况下，grappelli似乎提出了告诉auth.User未找到的问题。这意味着它无法找到任何包auth。如果您使用默认用户模型，请从配置中删除AUTH_USER_MODEL设置，或者如果您使用“auth”包中的任何自定义用户模型，请在已安装的应用中列出它。

Answer 2

如果您的应用程序未称为auth，则必须替换它：
AUTH_USER_MODEL='your_app_name.User'

Answer 3

一旦我在v-2.2中遇到了同样的问题，那么我意识到admin.py文件中“ register”的拼写错误。

Answer 4

完整的追溯将有助于更好地诊断它。首先，在我看来，由于迁移造成的依赖性问题。检查Django文档对此有何看法 -

由于Django的动态依赖功能的限制可交换模型，必须确保引用的模型 AUTH_USER_MODEL是在其应用程序的第一次迁移中创建的（通常是叫做0001_initial）;否则，您将遇到依赖性问题。

这是链接 - https://docs.djangoproject.com/en/1.9/topics/auth/customizing/

Answer 5

由于缺少admin.py（Django 2.2版）中的模型导入，也可能会出现此错误。

Answer 6

尝试先进行迁移； python manage.py makemigrations。这可能会检测您的导入是否有问题，可以修复然后运行服务器进行验证

Answer 7

我怀疑这是典型的答案，但是当我使用reverse并应该使用reverse_lazy时遇到了这个问题。更改为reverse_lazy对我来说是固定的。

Answer 8

当我配置的模型不正确并将其添加到管理后端时，会出现此错误。

Wrong:
   class VolunteerExperience:
 ...

Correct:
   class VolunteerExperience(models.Model):
 ...

我希望这可以帮助因异常消息"django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'auth.User' that has not been installed"误导的人

现在我知道此消息很可能表明模型配置错误。

Answer 9

这是因为您拥有一个定义了用户模型的应用程序“ 身份验证 ”。并且您没有在 INSTALLED_APPS 词典中提及应用名称。

尝试在 INSTALLED_APPS 中添加您的应用名称，然后检查。

Answer 10

除了所有其他答案之外，我在升级 Django 时遇到了这个问题。我有一个从一个版本到另一个版本不推荐使用的导入。在升级任何软件包之前，请务必检查发行说明/版本历史。
