迁移后在django应用程序上强制删除行

经过南迁移后，我最终删除了一列。现在在我的表之一的当前数据搞砸了，我想删除它，但尝试删除只是导致错误：迁移后在django应用程序上强制删除行

>>> d = Degree.objects.all() 
>>> d.delete() 
Traceback (most recent call last): 
    File "<console>", line 1, in <module> 
    File "C:\Python26\lib\site-packages\django\db\models\query.py", line 440, in d

    for i, obj in izip(xrange(CHUNK_SIZE), del_itr):

    self._fill_cache() 
    File "C:\Python26\lib\site-packages\django\db\models\query.py", line 760, in _

200, in execute 
    return Database.Cursor.execute(self, query, params)

有一个简单的办法只有强制删除？我是否删除表，然后重新运行manage.py schemamigration以在南方重新创建表？

你可以使用

python manage.py reset [YOUR APP NAME]

但它会从该应用程序的所有表中删除所有数据。

或者你可以运行普通的旧SQL，删除该表并重新运行迁移

> mysql -p -h HOST -u USER DATABASE_NAME 
>> DROP TABLE APPNAME_degree; 
>> exit; 
> python manage.py migrate
