我通过评论模型从我的数据库中删除了模型名称 controlapproval 和 运行 python manage.py makemigrations 但是当我尝试使用 python manage.py migrate 进行迁移时 它会抛出如下错误

任何帮助或指导都会有很大帮助

Answer 1

1. 从项目根目录中删除 migrations 文件夹。
2. 创建一个新的migrations 文件夹。
3. 在该文件夹中添加一个__init__.py 空文件。
4. 运行python manage.py makemigrations 和python manage.py migrate。

这只会为您的项目创建一个新的迁移。
