django - Heroku Django-Admin 500 错误？

Question

将一个新应用程序部署到 Heroku 应用程序，该应用程序在 myapp.herokuapp.com 上运行良好，但如果我尝试访问 myapp.herokuapp.com/admin 上的管理后端，则会引发 500 服务器错误

INSTALLED_APPS = (
    ...
    'django.contrib.admin',
    'gunicorn',
    'storages',
    # 'django.contrib.admindocs',

)

这是日志摘录:

哪些设置会导致应用程序正常运行但在/admin 上引发 500 错误？我可能忽略或遗漏了什么？谢谢。

感谢 Magnus 的推荐，我在我的项目中添加了哨兵，并发现了一个 postgres DatabaseError:relation issue 由于我没有在 heroku 上成功迁移的项目应用程序。

修复只是做了一个假的并完成了迁移的其余部分。

heroku run python manage.py migrate app 0016 --fake
heroku run python manage.py migrate
