django south fresh install - >错误:未知命令'schemamigration'

Question

短篇故事

我./manage.py schemamigration junk_app --initial刚刚安装完南(http://south.aeracode.org/)之后就运行了一个全新的django项目,我收到以下错误:

Unknown command: 'schemamigration'
Type 'manage.py help' for usage.

编辑:我有版本.7(南/ init.py有版本 =".07")

很长的故事

Answer 1

您可能没有将"south"添加到settings.py文件的INSTALLED_APPS列表中.

以下是http://south.aeracode.org/docs/installation.html#installation-configure的引用

现在您已经在系统范围内安装了South,您需要配置Django才能使用它.这样做很简单; 只需编辑您的settings.py并将"south"添加到INSTALLED_APPS的末尾.

如果Django似乎没有选择它,请检查你是否在其他地方没有覆盖INSTALLED_APPS,并且你可以从./manage.py shell内部运行import south而没有错误.

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

Answer 2

您可能正在使用一些旧的South版本,0.6.x甚至0.5.x. 如果键入"./manage.py help",则应startmigration在可用命令列表中看到(iirc).
