我最近将Django升级到1.8并建立了一个新的开发数据库,以便重新开始。迁移和依赖关系进展顺利,安全通常会出现错误并最终解决问题。该应用程序现在正在本地工作。
但是,我在尝试运行测试时遇到错误:
python manage.py test
这是我得到的错误:
django.db.utils.ProgrammingError: relation "auth_user" does not exist
毋庸置疑,Django的auth模块确实已在应用程序中安装和迁移,因此我不确定发生了什么。
以下是完整的堆栈跟踪,以防你需要查看它,但它没有说任何东西,甚至远程帮助我找出导致此错误的原因:

我可以找出this answer之后的解决方法,它阻止测试任务运行migrate
,根据我一直在阅读的内容应该是错误发生的地方。奇怪的是,因为当我跑migrate
时一切都很好。
但是,我宁愿不采取厚颜无耻的解决方法,坚持按照设计的方式做事。此外,这个错误可能暗示其他东西实际上是错误的,应该修复。
有些解决方案建议运行:
python manage.py migrate auth
python manage.py migrate
但由于我的项目中没有待定的迁移,因此无效。
我该如何解决这个神秘的问题?
答案 0 :(得分:1)
如果您有任何具有auth.User
外键的应用,请确保这些应用的初始迁移在auth应用上有dependency:
class Migration(migrations.Migration):
dependencies = [('auth', '__first__')]
答案 1 :(得分:0)
我遇到了同样的问题,当我迁移了项目中包含的一个应用程序但该迁移不会自动执行时,终于解决了。
因此,只需检查您的应用,然后手动执行./manage.py makemigrations YOUR_APP_NAME
和./manage.py migrate
。
