无法使用Heroku部署的应用程序登录Django管理界面

Question

有点奇怪的问题，但我无法使用Heroku部署的Django应用程序登录到管理界面。每当我输入正确的凭据时，都会收到一条错误消息，指出Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive.我可以在Shell中以及在运行简单的本地django服务器时在本地进行身份验证，但不能在使用heroku部署的版本中进行身份验证。有什么想法吗？这是我的settings.py档案。它是使用Heroku配置的模板自动生成的，并使用此命令运行$ django-admin startproject --template=https://github.com/heroku/heroku-django-template/archive/master.zip --name=Procfile myproject

我遇到了类似的问题。然后我通过运行创建了一个超级用户：

$ heroku run python manage.py createsuperuser

然后：

$ git push -f heroku master
$ heroku run python manage.py migrate

它工作得很好。

我面临类似的错误，但是我注意到你的settings.py中的一些东西我觉得应该改变，当你迁移到heroku时，默认数据库需要更改为postgresql，如下所示

DATABASES = {
'default': {
    'ENGINE': 'django.db.backends.postgresql',
    'NAME': 'mydatabase',
    'USER': 'mydatabaseuser',
    'PASSWORD': 'mypassword',
    'HOST': '127.0.0.1',
    'PORT': '5432',
}

}

您将在 Heroku 应用程序的资源选项卡 -> 附加组件 -> postgresql -> 查看凭据中找到这些凭据。

请参阅以下链接了解详细信息：

https://docs.djangoproject.com/en/1.11/ref/settings/#std:setting-DATABASES

希望这可以帮助！
