DatabaseError“no such column”

Question

由于某种原因，我得到一个DatabaseError "no such column: myapp_customer.redirect_link_id"。在另一台计算机上与我具有完全相同的代码的人没有此问题。我们使用Django南迁移，并根据它我完全了解最新的型号：

$ 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. 

这里是一个完整的堆栈跟踪：

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

我跑manage.py sqlall myapp，并根据它， redirect_link_id存在于数据库中：

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") 
) 
;

您确定您还拥有myapp/migrations目录中最新的迁移文件吗？
