DatabaseError「no such column」

由於某種原因，我得到一個DatabaseError "no such column: myapp_customer.redirect_link_id"。在另一臺計算機上與我具有完全相同的代碼的人沒有此問題。我們使用Django南遷移，並根據它我完全瞭解最新的型號：DatabaseError「no such column」

$ python manage.py schemamigration myapp --auto 
Nothing seems to have changed. 

$ python manage.py migrate myapp 
Running migrations for myapp: 
- Nothing to migrate. 
- Loading initial data for myapp. 
No fixtures found.

這裏是一個完整的堆棧跟蹤：

Exception Type: DatabaseError at/
Exception Value: no such column: myapp_customer.redirect_link_id

我跑manage.py sqlall myapp，並根據它， redirect_link_id存在於數據庫中：

CREATE TABLE "myapp_customer" (
    "id" integer NOT NULL PRIMARY KEY, 
    "user_id" integer NOT NULL UNIQUE REFERENCES "auth_user" ("id"), 
    "client_key" varchar(9) NOT NULL UNIQUE, 
    "api_key" varchar(30) NOT NULL UNIQUE, 
    "redirect_link_id" integer REFERENCES "myapp_full_link" ("id"), 
    "message_title" varchar(200), 
    "message_body" text, 
    "customer_group_id" integer NOT NULL REFERENCES "myapp_customer_group" ("id") 
) 
;

'myapp_full_link'表已存在且具有完整性？ – 2012-02-02 08:37:20

sqlall不會顯示數據庫的當前狀態。它顯示了從頭開始設置數據庫所需的SQL。使用dbshell命令，然後'.schema'（對於SQLite） – Alasdair 2012-02-02 09:38:40

因此，根據sqllite，myapp_customer表實際上沒有'redirect_link_id'列。 myapp_full_link確實存在問題：爲什麼南遷移沒有根據我的模型創建列？ – babonk 2012-02-02 20:03:07

您確定您還擁有myapp/migrations目錄中最新的遷移文件嗎？

我很確定。我再次檢查了工作機器，並且沒有任何未跟蹤的遷移。 – babonk 2012-02-02 06:43:09

''./manage.py migrate --list''也可能給出一些關於遷移狀態的指針。除此之外，我建議檢查數據庫級別的實際當前模式，並將其當前狀態與south_migrationhistory表中的遷移記錄進行比較，以查看錯誤發生的位置。 – Raekkeri 2012-02-02 06:53:25

工作機器和非工作機器具有與該命令相同的輸出。另外，請參閱上文，我運行了manage.py sqlall，它似乎意味着我有實際的分區 – babonk 2012-02-02 07:00:33
