Question

我一直在研究Django应用程序，最近遇到了一些问题，推动更新并将数据库设置从Local迁移到Heroku。

我按照以下步骤操作：

我在我的应用模型中添加了几列。
然后运行python manage.py makemigrations
然后python manage.py migrate。
然后我通过github提交了这些更新。
然后我跑了git push heroku master w / Heroku CLI
然后我输入了heroku run python manage.py migrate

不幸的是，这并未将我所做的相应更新迁移到本地开发环境中的数据库设置。我收到的错误消息是“X-app中不存在列x”。我最终暂时恢复到我之前在model.py中的设置，但我想最终在我的数据库中添加新列。

此时，我正在尝试评估问题的最佳解决方案。我已经回顾了其他几个Stack Overflow问题，但还没有找到一个对我有用的问题。奇怪的是，我能够在以前的Heroku部署中成功迁移。

任何人提出的任何提示都将非常感激。作为参考，我使用的是Python 3.6.2和Django 1.11
