[django + mysql] MySQLdb.connect工作正常，但无法通过settings.py连接mysql

Question

我试图用django连接mysql。下面的命令可以正常工作。

import MySQLdb 
>>> con = MySQLdb.Connect(host = "127.0.0.1", port= 3306, user = "root", passwd = "mycode", db = "test") 
>>> con.cursor() 
<MySQLdb.cursors.Cursor object at 0x020F2230> 
>>> cursor = con.cursor() 
>>> sql = "SELECT * FROM test.testing" 
>>> cursor.execute(sql) 
0L 

当我尝试通过settings.py连接数据库，它打破了，我可以找到有关it.Here的我的配置settings.py中

DATABASES = { 
    'default':{ 
     'ENGINE' : 'django.db.backends.mysql', 
     'NAME' : 'tasty', 
     'USER' : 'root', 
     'PASSWORD' : 'mycode', 
     'DATABASE_HOST' : '127.0.0.1', 
     'DATABASE_PORT' : '3306', 
    }, 
} 

该错误消息我不知道从命令行，如下所示。我怀疑我得到错误的原因，是Django无法获取适当的参数为数据库连接。我的环境是win7 32bit，python 2.7.5，django 1.6.7，mysql 5.1，MySQL-python- 1.2.4b4.win32-py2.7.Please有人帮助我，任何建议将不胜感激。

为DB的设置应该是HOST和PORT，不DATABASE_HOST ......那么试试这个：

DATABASES = { 
    'default':{ 
     'ENGINE' : 'django.db.backends.mysql', 
     'NAME' : 'tasty', 
     'USER' : 'root', 
     'PASSWORD' : 'mycode', 
     'HOST' : '127.0.0.1', 
     'PORT' : '3306', 
    }, 
}
