Question

我正在使用Django 1.8，我有一个应用程序运行完全正常。但现在我迁移了整个数据库，每当我尝试访问管理员中的记录时，我都会收到此错误：

Internal Server Error: /admin/mitglieder/mitglied/22/

我用1.7开始了这个项目，但我已经转移到1.8并且一个应用程序运行没有问题。但是，我以前没有迁移过整个项目。我从迁移历史记录中看到的是，此迁移在auth应用程序上进行了迁移。但即使我在此之前迁移回来，我也会遇到同样的错误。

切换到1.8之前我遇到过这个或类似的错误，但这不是name字段的问题。而且我无法删除数据库中的django_content_types表，因为auth链接到此表。我可以以某种方式解决这个问题吗？

因此，确保dev-server和生产服务器在Django 1.8上运行后，一切运行良好。我在启动脚本的环境路径中遇到了一些困惑。
