TL;DR - 使用 django-custom-user和django-registration-redux，即使在原始实例上，我也无法设置 postgres 数据库。它抱怨不存在的关系，我不明白为什么或在哪里。以下问题的详细信息不长，但包含一些长度适中的错误片段。任何指针都非常感谢。

使用 django-custom-user，我了解到我必须先对 custom_user 进行迁移，然后才能进行剩余的迁移。很公平。在一个干净的实例上（刚刚创建了一个数据库并 git clone'd 代码），我输入

python manage.py makemigrations custom_user
python manage.py makemigrations
python manage.py migrate

但是...不，我缺少 custom_user_emailuser。我怀疑这意味着 custom_user 与 key emailuser 的关系，但我仍然发现自己很难理解这是从哪里来的，所以该怎么做。非常感谢任何提示。

The above exception was the direct cause of the following exception:

我不明白，更糟糕的是因为 custom_user 迁移不需要这样的事情：

事实证明，custom_user必须在世界其他地方之前迁移，sites甚至在custom_user. 所以这解决了我们的问题：

python manage.py migrate sites
python manage.py migrate custom_user
python manage.py migrate
