部署Heroku后无法登录管理面板

Question

所以我部署了一个Django rest框架到Heroku，在设置了PostgreSQL之后，运行迁移命令并创建了一个超级用户，我似乎无法登录到我的Django管理面板。下面是我的settings.py文件。

我以前在Heroku上主持过2个项目，我从来没有经历过这种情况，如果有人能告诉我我做错了什么，我会非常感激。

我解决了问题。我做了以下的事情来解决这个问题

• 运行python manage.py shell以能够使用python shell
• 通过运行from appname.models import ModelName导入我的自定义用户模型，如果您使用内置用户模型，只需执行from django.contrib.auth.models import User
• 使用user = ModelName.objects.get(username="superuser's username")或User.objects.get(username="superuser's username")，如果您使用内置用户模型来获取我创建的超级用户
• 然后我通过user.set_password('newpassword')和user.save()更改了超级用户的密码。

返回到管理员的登录页面，再次输入超级用户的凭据，您应该登录到管理面板。

我希望这能帮助到有类似问题的人。
