Question

TL; DR - 使用django-custom-user 和 django-registration-redux，即使在原始实例上也无法设置postgres数据库。它抱怨不存在关系，我不明白为什么或在哪里。下面问题的详细信息不长，但包含一些中等长度的错误摘要。任何指针都非常赞赏。

使用django-custom-user，我了解到在剩余的迁移工作之前我必须先为custom_user进行迁移。很公平。在一个干净的实例上（刚刚创建了一个数据库并git克隆了代码），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。我怀疑这意味着来自关键emailuser上的custom_user的关系，但我仍然发现自己难以理解它的来源，以及如何处理它。任何提示都非常感激。

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

我不明白，更糟糕的是因为custom_user迁移不会调用这样的东西：

Answer 1

事实证明custom_user必须在世界其他地方之前迁移，但sites甚至在custom_user之前迁移。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

django-custom-user和custom_user_emailuser（不存在）
