database - Django model-database changes

Question

I have a legacy database that I'm using in an app in Django. I used the django admin functionality to generate the models.py file from the existing tables.

If I make changes to the models, such as adding a unique_together constraint to models, are the changes managed by Django, or do I have to somehow apply said model changes to the database?

Answer 1

为了让 django 检测到更改，您需要使用名为south. 现在，由于您已经提交了运行的意思python manage.py syncdb，您需要删除表并重新开始。

这就是你的做法（在你删除你的表之后）：

1. 使用南安装pip install south
2. 将南添加到已安装的应用程序中，并确保它位于您创建的所有其他应用程序之前
3. 运行这个：python manage.py schemamigration --inital <your app name>
4. 运行这个：python manage.py migrate <your app name>
5. 运行这个：python manage.py syncdb<-最后一次你需要运行它:)

希望这有帮助。
