InvalidBasesError：无法解析[< ModelState：'users.GroupProxy'>]的基础 [英] InvalidBasesError: Cannot resolve bases for [<ModelState: 'users.GroupProxy'>]

问题描述

当我运行测试时，我在数据库初始化期间得到这个错误：

When I run tests I get this error during database initialization:

django.db.migrations.state.InvalidBasesError: Cannot resolve bases for [<ModelState: 'users.GroupProxy'>]
This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth)

我创建了这个代理，用于contrib.auth组模型，将其放在我的应用程序中，在django admin中：

I created this proxy for contrib.auth Group model to place it in my app in django admin:

class GroupProxy(Group):
    class Meta:
        proxy = True
        verbose_name = Group._meta.verbose_name
        verbose_name_plural = Group._meta.verbose_name_plural

那么我可以做些什么来解决这个问题？

So what can I do to fix this issue?

推荐答案

经过很多挖掘，对我来说唯一有用的是

After a lot of digging on this the only thing that worked for me was

注释掉有罪的应用程序，运行迁移，然后重新添加。

只是一个解决方法，但希望它h elps somebody。

Just a workaround but hopefully it helps somebody.
