django-cms 迁移错误

  • 772

在 django-cms 中创建了一个访问 Title 模型的医生表。在服务器上迁移时，出现以下文本形式的错误。谷歌搜索了很多，没有任何帮助。我可以从迁移文件夹中删除所有迁移并运行 makemigrations 并且它会工作，但问题是如果表被更改，那么迁移将不会被应用。那么问题来了，我该如何修复这个错误，以便每次我不删除迁移并重置数据库。

我稍微想通了这个问题。迁移编号 0023 是在创建从 django-cms 到表的 ForeignKey 的表迁移时创建的，目前尚不知道如何解决此问题。我在等你的帮助。

    1. 我解决了这个问题，虽然不是很正确，但它可以正常工作。我将本地机器上的文件名更改为服务器的名称，即将0023_auto_20211115_1737.py更改为0023_auto_20211110_1234.py。同样在本地机器的数据库中的 django_migrations 表中，我将 name=0023_auto_20211115_1737.py 所在的条目更改为 name=0023_auto_20211115_1737.py。

    2. 我还对这个问题使用了另一种解决方案，这不是很方便，我只是从破坏所有迁移的提交中的文件中删除了文件。
