Heroku 不识别迁移

Question

我终于让我的 Heroku 应用至少可以在本地运行了！但是，当我尝试在线打开它时，它崩溃并出现以下错误：

我不太确定该怎么做，但是当我运行本地应用程序时，它说：

它说我有 20 个未应用的迁移，难道这就是它不能联机工作的原因吗？在进行迁移然后迁移时，它只是说没有要应用的迁移。

大多数人似乎建议对 Procfile 进行一些更改，但我不太了解 Procfiles，也不知道要写什么或为什么要写它。无论如何，我没有找到任何似乎适用于我的应用程序的东西，其中大部分似乎是关于 JSON.

Answer 1

首先确保您在项目设置中设置了正确的数据库设置，

Most people seem to suggest some change to the Procfile but I don't understand Procfiles

他们可能建议您将此行添加到您的 Procfile

release: python manage.py migrate

这个问题看起来也很相似，从你分享的信息中不太了解你的项目流程是什么，但也许对这个有帮助question
