【Error】InterfaceError (0, '')

也不知道什么时候接触到的这个错误，暂且记录下。

错误描述：InterfaceError (0, '')

Traceback:
File "/usr/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
100.                     response = callback(request, *callback_args, **callback_kwargs)

File "build/bdist.linux-i686/egg/MySQLdb/cursors.py" in execute
155.         charset = db.character_set_name()

Exception Type: InterfaceError at /blablabla/
Exception Value: (0, '')

解决方法：

该错误是设置全局游标对象引起的，请尝试在每个方法调用时创建和关闭游标对象。

cursor = connection.cursor()
cursor.execute(query)
cursor.close()
