file:adminx.py
xadmin
xadmin views
BaseSetting():
enable_themes = use_bootswatch = Some Codes...
xadmin.site.register(views.CommAdminViewGlobalSettings)
file:__init__.py
default_app_config = "users.apps.UsersConfig"
错误原因：
当use_bootswatch 为True的时候，就会使用httplib2去
http://bootswatch.com/api/3.json
网址获取主题菜单项。但是使用浏览器打开这个网址，http会被替换成https的。httplib2访问这个https的网址，就会报错。报错信息为：
[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure
这边使用requests库来替代httplib2.
在xadmin的源码目录下修改xadmin\plugins\themes.py:

site.register_plugin(ThemePlugin, BaseAdminView)
然后就可以调出企业常用的各种主题样式了。
