django - 部署 Heroku 后无法登录管理面板

问题描述

所以我向 Heroku 部署了一个 Django REST 框架，在设置 PostgreSQL、运行 migrate 命令并创建一个超级用户之后，我似乎无法登录到我的 Django 管理面板。下面是我的 settings.py 文件。

Django settings for ptracker project.

Generated by 'django-admin startproject' using Django 3.1.4.

django_heroku.settings(locals())

我以前在 Heroku 上主持过 2 个项目，但我从未经历过这种情况，如果有人能告诉我我做错了什么，我将不胜感激。

解决方案

我解决了这个问题。我做了以下来解决这个问题

  • 跑到python manage.py shell能够使用python shell
  • from appname.models import ModelName如果您使用的是内置用户模型，则通过运行导入我的自定义用户模型，只需执行from django.contrib.auth.models import User
  • 使用过user = ModelName.objects.get(username="superuser's username")，或者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
  • user.set_password('newpassword')然后我通过执行然后更改超级用户的密码user.save()。

返回管理员的登录页面并再次输入超级用户的凭据，您应该会登录到管理面板。

我希望这可以帮助有类似问题的人。
