OperationalError at/admin/Survey/intro/add/

Question

我正在編寫一個簡單的管理表單，但即使我已經完成了makemigration並遷移了很多次，它並沒有顯示更新，但沒有這樣的表的錯誤仍然顯示出來。

回溯：

File "C:\Python34\lib\site-packages\django\db\backends\utils.py" in execute 65. return self.cursor.execute(sql, params) 
File "C:\Python34\lib\site-packages\django\db\backends\sqlite3\base.py" in execute 328. return Database.Cursor.execute(self, query, params) 
The above exception (no such table: Survey_intro) was the direct cause of the following exception:

如果Survey應用程序尚未進行任何遷移，那麼在進行遷移時您需要包含應用程序名稱。

python manage.py makemigrations Survey 
python manage.py migrate 

順便說一句，在Python/Django的通常的做法是命名您的應用程序survey，你的模型Intro，和你的類IntroForm和IntroAdmin。
