为什么在运行“ migrate”时出现“ auth_user不存在”错误？在新创建的带有“ registration redux”的django项目上应用安装了吗？ [英] Why do I get a "auth_user does not exist"error when running "migrate" on a newly created django project with "registration redux" app installed?

问题描述

使用以下已安装的应用程序创建一个新的django项目：

Given a newly created django project with the following installed apps:

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'registration',
)

当我第一次运行./manage.py时，出现以下错误：

When I run ./manage.py migrate for the first time I get the following error:

Operations to perform:
  Synchronize unmigrated apps: staticfiles, messages, registration
  Apply all migrations: sessions, admin, auth, contenttypes
Synchronizing apps without migrations:

似乎Django试图在创建注册表之前用户表。

It seems Django is trying to create the registration tables before the user table.

如果我注释了注册应用程序并运行迁移，然后取消注释了注册应用程序并再次运行迁移，则不会发生此错误。但是，那不是正确的方法，对吧？

This erros does not happen if I comment the registration app and run migrate and then uncomment the registration app and run migrate again. However, that's not the right way of doing it, right?

推荐答案

更新Django版本后，出现此错误并修复运行以下两行：

After updating my Django version, I got this error and fix as running these two lines:

python manage.py migrate auth
python manage.py migrate

我想应该首先运行auth模型中的auth_user表。

auth_user table inside auth model should run first I guess.
