Django South初始迁移错误

Question

我有一个新的Django 1.3项目和我创建的应用程序.我向南添加了我settings.py还没有跑syncdb.当我按照南方教程和文档执行以下命令时,我收到了如下所示的错误.

• 有关导致问题的原因的任何想法？更新:未正确安装South(请参阅答案).
• South 0.7.3与Django 1.3兼容吗？更新:是的.

执行的命令和南错误

Answer 1

Ken Cochrane对StackOverflow问题的回答如何让我的南方迁移对Django不起作用.

对于新的Django项目和应用程序,我必须执行以下步骤:

1. 加入南向INSTALLED_APPS的settings.py,但不加你的应用程序
2. 运行syncdb以将Django和South表添加到数据库.南方改变了syncdb,所以在你的南方拥有南方很重要INSTALLED_APPS.
3. 添加应用,以INSTALLED_APPS在settings.py
4. python manage.py schemamigration app_name --initial为每个应用运行
5. 跑 python manage.py migrate app_name

阅读说明书 - 否,所有说明

我很高兴开始使用South,我跳过阅读安装文档.我只是安装南使用pip install south,然后只是添加到我的INSTALLED_APPS.那是我的错.

安装文档的 " 配置Django安装"部分指出:

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