我試圖按照Django網站上的「編寫你的第一個Django應用程序」教程，我被困在第2部分關於數據庫的東西。Django遷移MySQL錯誤
我正在運行Ubuntu 14.04和Python 3.4。
我已經安裝了MySQL和Python的MySQL的庫並提出在MySQL數據庫中名爲testdb的，但試圖運行命令時
python3 manage.py migrate
我得到以下錯誤：
server1:~/Desktop/app/mysite$ python3 manage.py migrate

The above exception was the direct cause of the following exception:

我django中的數據庫設置看起來像這樣
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'testdb',
'USER': 'root',
'PASSWORD': 'xxxx',
'HOST': '127.0.0.1',
}
}
我對b做出的唯一更改ase django項目模板是添加一個應用程序，一些url映射，並對數據庫設置進行更改，並將後端切換到sqlite工作正常。
任何幫助搞清楚這將是很棒，謝謝。
編輯：這是我安裝的應用程序，網址，我還沒有任何模型。

'_mysql_exceptions.ProgrammingError：（1064，「您的SQL語法錯誤;檢查手冊，該手冊對應於你的MySQL服務器版本，在第一行'％s'附近使用正確的語法'）' - 這會給你提示錯誤可能存在的提示。從'settings.py'加入'INSTALLED_APPS'和最後加上'models.py'將會很有幫助。 – cezar
我添加了安裝的應用程序和網址，我的models.py完全是空的。我知道有一個地方的問題，但是當mysql由django生成時，我不知道從哪裏開始尋找。 –
因此，在'％s'附近使用的消息''WHERE table_name =％s'，[table_name]'和'語法給了我一個關於空表名的想法。如果'models.py完全爲空'且您的'polls'應用程序不存在INSTALLED_APPS中，您會遷移什麼？ - 也許你應該用syncdb創建一個基本的方案？ –
