的Django /南設立失敗有關python manage.py schemamigration testapp --initial

Question

我試圖建立南方首次對我的開發環境。我有幾個模型已經安裝過。一旦南安裝完成，我跟隨南的文檔轉換我現有的應用程序。

不過，我收到下面的回溯。有任何想法嗎？

謝謝。

這是我的型號代碼。

我有ATLEAST二十個表是已經與執行syncdb工作。我只是想轉換爲南方，因爲放置桌子和重新創建是一件麻煩事。我已經移除了大部分的模型代碼來排除故障，這是剩下的。即使如此，我也得到了相同的回溯。

爲了讓南方用戶開始跟蹤預先存在的表格，您必須在安裝後立即運行syncdb。換句話說，您應該按照下列步驟操作：

$ pip install south 
$ nano settings.py 
Add south to installed apps & save 
$ python manage.py syncdb 
$ python manage.py convert_to_south <app>
