数据库错误“没有这样的列”

Question

由于某种原因，我收到DatabaseError“没有这样的列：myapp_customer.redirect_link_id”。在另一台计算机上具有与我完全相同的代码的人不会出现此问题。我们使用 Django-South 进行迁移，根据它，我完全了解该模型：

$ 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.

这是完整的堆栈跟踪：

Traceback:

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

我运行了 manage.py sqlall myapp 并根据它，redirect_link_id 是存在于数据库中：

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 目录中的最新迁移文件吗？
