named _restful_mysql的错误如何解决？

[崔利伟]

我的index文件：

import sae
import os
import sys
from blog import wsgi


app_root = os.path.dirname(__file__)
sys.path.insert(0, os.path.join(app_root, 'blog'))
os.environ['DJANGO_SETTINGS_MODULE'] = 'blog.settings'


application = sae.create_wsgi_app(wsgi.application)


import django.core.handlers.wsgi


application = sae.create_wsgi_app(django.core.handlers.wsgi.WSGIHandler())

报错信息：
