BaseSetting():
    enable_themes = use_bootswatch = Some Codes...
xadmin.site.register(views.CommAdminViewGlobalSettings)

file:__init__.py

default_app_config = "users.apps.UsersConfig"

錯誤原因：

當use_bootswatch 為True的時候，就會使用httplib2去

http://bootswatch.com/api/3.json
 

網址獲取主題菜單項。但是使用瀏覽器打開這個網址，http會被替換成https的。httplib2訪問這個https的網址，就會報錯。報錯信息為：

[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure

這邊使用requests庫來替代httplib2.

在xadmin的源碼目錄下修改xadmin\plugins\themes.py:

然後就可以調出企業常用的各種主題樣式了。
