Django 1.8 test issue: ProgrammingError: relation "auth_user" does not exist

Question

我最近将 Django 升级到 1.8 并设置了一个新的开发数据库以重新开始。迁移和依赖关系进行得很顺利，避免了你遇到的常见错误，你最终解决了。该应用程序现在在本地运行正常。

但是，我在尝试运行测试时遇到错误：

python manage.py test

这是我收到的错误：

django.db.utils.ProgrammingError: relation "auth_user" does not exist

不用说了，Django的auth模块确实是在app里面安装和迁移的，所以我也不知道是怎么回事。

这是完整的堆栈跟踪，以防您需要查看它，但它并没有说明任何对我找出此错误原因的远程帮助：

我可以在 this answer 之后想出一个解决方法，它可以防止测试任务从运行宁 migrate，根据我一直在阅读的内容，这应该是错误的地方发生。够奇怪的，因为当我运行 migrate 一切都很好。

但是，我宁愿不诉诸厚颜无耻的解决方法，而是坚持按设计做事。此外，此错误可能暗示其他问题实际上是错误的并且应该被修复。

一些解决方案建议运行ning:

python manage.py migrate auth
python manage.py migrate

但这没有任何作用，因为我的项目中没有待处理的迁移。

我该如何解决这个神秘的问题？

Answer 1

如果您有任何具有指向 auth.User 的外键的应用程序，请确保这些应用程序的初始迁移在授权应用程序上具有 dependency：

class Migration(migrations.Migration):

    dependencies = [('auth', '__first__')]

Answer 2

我遇到了同样的问题，当我迁移了项目中包含的应用程序之一但迁移不会自动执行时，问题终于解决了。

所以只需检查您的应用程序，然后手动执行 ./manage.py makemigrations YOUR_APP_NAME 和 ./manage.py migrate。
