当使用下面方式引入xadmin样式的时候发现并没有效果：

file:adminx.py

xadminxadmin 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:

                cache.set(THEME_CACHE_KEY, json.dumps(ex_themes), 24 * 3600)                themes.extend(ex_themes)

        nodes.append(loader.render_to_string('xadmin/blocks/comm.top.theme.html', {'themes': themes, 'select_css': select_css}))

site.register_plugin(ThemePlugin, BaseAdminView)

然后就可以调出企业常用的各种主题样式了。
