Ken Cochrane's answer to the * question How Come My South Migrations Doesn't Work for Django held the key.

Ken Cochrane对*问题的回答如何让我的南迁移对Django不起作用。

For a new Django project and app, I had to perform the following steps:

对于新的Django项目和应用程序，我必须执行以下步骤：

1. Add South to INSTALLED_APPS in settings.py, but do not add your apps
2. 在settings.py中将South添加到INSTALLED_APPS，但不添加您的应用
3. Run syncdb to add the Django and South tables to the database. South modifies syncdb, so it's important to have South in your INSTALLED_APPS.
4. 运行syncdb将Django和South表添加到数据库。 South修改了syncdb，因此在INSTALLED_APPS中使用South非常重要。
5. Add apps to INSTALLED_APPS in settings.py
6. 在settings.py中将应用添加到INSTALLED_APPS
7. Run python manage.py schemamigration app_name --initial for each app
8. 为每个应用程序运行python manage.py schemamigration app_name --initial
9. Run python manage.py migrate app_name
10. 运行python manage.py migrate app_name

Read the instructions—No, all of the instructions

I was so excited to start using South that I skipped reading the installation documentation. I simply installed South using pip install south and then just added it to my INSTALLED_APPS. That was my mistake.

我很高兴开始使用South，我跳过阅读安装文档。我只是使用pip install south安装South，然后将它添加到我的INSTALLED_APPS中。那是我的错。

The Configuring Your Django Installation section of the installation documentation states:

安装文档的配置Django安装部分说明：

Once South is added in, you’ll need to run ./manage.py syncdb to make the South migration-tracking tables (South doesn’t use migrations for its own models, for various reasons).

一旦添加了South，您将需要运行./manage.py syncdb以生成南迁移跟踪表（由于各种原因，South不会为其自己的模型使用迁移）。
