最近使用django开发一个小网站,后台管理系统采用xadmin,xadmin是采用源代码的方式引入到项目中,在xadmin使用的过程中,设置“use_bootswatch = True”,企图调出主题菜单,显示更多主题,但是设置后却发现无效,发现主题还是默认和bootstrap2
这里我特意去github上找到xadmin这个项目,有跟我一样问题的解决方法
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。
点击进去看之后,有人提供的解决方法如下:
(有颜色部分的就是源码有修改的地方)
解决步骤:
1.安装requests
pip install requests
2./xadmin/plugins/themes.py 引入requests(如果少了httplib2的也要引入)
import requests
3.修改block_top_navmenu方法:
如果大家嫌麻烦,直接把我这个theme.py内容文件复制过去就行
