Django Heroku users_customuser表无法迁移

Question

我有一个在本地开发了一段时间的Django项目。它在我的本地计算机上运行良好，并且我使用的是customuser设置，因此我的登录身份验证仅需要电子邮件/密码，而默认的Django用户表则需要电子邮件/用户名/密码。

我刚刚将项目托管在Heroku上，并且可以看到网页UI加载良好。但是单击任何链接时出现Django错误，并在尝试运行

时认为它与问题有关

heroku run python manage.py migrate

我正在尝试在heroku上运行此程序以设置数据库，但是这样做时出现错误消息：

Running python manage.py migrate on ⬢ songsweeper... up, run.1353 (Free)
Operations to perform:
  Apply all migrations: account, admin, auth, contenttypes, playlist, sessions, sites

The above exception was the direct cause of the following exception:

我的项目很大，但是要概述我定义customuser的位置，它会出现在以下位置：

是否有人对如何解决此迁移错误有任何建议？还是指示性的或更有用的？我网站上的“登录”链接导致另一个错误，提示“关系“ django_site”不存在”，但我认为这与失败的customuser错误有关。

我当前正在使用默认的sqlite3 db。

Answer 1

我之前遇到过和你类似的问题。 在我看来，我认为这是因为用户应用程序中的迁移文件。 因此，您必须迁移用户模型。

List<CustomerGroup> listC = listA.Except(listB, new CompareCustomerGroup()).ToList(); 

我用上面的方法解决了这个问题。
