遷移後在django應用程序上強制刪除行

經過南遷移後，我最終刪除了一列。現在在我的表之一的當前數據搞砸了，我想刪除它，但嘗試刪除只是導致錯誤：遷移後在django應用程序上強制刪除行

>>> 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 
elete 
    for i, obj in izip(xrange(CHUNK_SIZE), del_itr): 
    File "C:\Python26\lib\site-packages\django\db\models\query.py", line 106, in _ 
result_iter 
    self._fill_cache() 
    File "C:\Python26\lib\site-packages\django\db\models\query.py", line 760, in _ 
fill_cache 
    self._result_cache.append(self._iter.next()) 
    File "C:\Python26\lib\site-packages\django\db\models\query.py", line 269, in i

    for row in compiler.results_iter(): 
    File "C:\Python26\lib\site-packages\django\db\models\sql\compiler.py", line 67 
2, in results_iter 
    for rows in self.execute_sql(MULTI): 
    File "C:\Python26\lib\site-packages\django\db\models\sql\compiler.py", line 72 
7, in execute_sql 
    cursor.execute(sql, params) 
    File "C:\Python26\lib\site-packages\django\db\backends\util.py", line 15, in e 
xecute 
    return self.cursor.execute(sql, params) 
    File "C:\Python26\lib\site-packages\django\db\backends\sqlite3\base.py", line 
200, in execute 
    return Database.Cursor.execute(self, query, params) 
DatabaseError: no such column: students_degree.abbrev

有一個簡單的辦法只有強制刪除？我是否刪除表，然後重新運行manage.py schemamigration以在南方重新創建表？

你可以使用

python manage.py reset [YOUR APP NAME]

但它會從該應用程序的所有表中刪除所有數據。

或者你可以運行普通的舊SQL，刪除該表並重新運行遷移

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