我在 AWS 中安装了应用程序并创建了一个新数据库。
我运行了 python manage.py migrate
但出现以下错误。
我用的是mysql。我不知道架构中发生了什么变化。
请帮帮我。

最佳答案
我确实喜欢“python manage.py migrate --fake”
到目前为止，它似乎已经完成了迁移。
似乎--fake选项是在模块中传递旧 Action ，这样新安装就不会受到旧 Action 的影响，只需安装新 Action 。
但是，在这种情况下，不会为 cms 创建架构。 --fake 选项不是解决方案。有人成功了吗？
要执行的操作: 应用所有迁移:menu、menus、admin、currency、auth、dashboard、cms、contenttypes、sites、session

python 管理.py 迁移

最后，我运行了“python manage.py managa.py cms --run-syncdb”。 执行此操作后，将创建 0008_auto_20150121_0059.py 的后续内容。
