django中设置use_bootswatch=True无效的解决办法

首先，原因是python2.7django1.9xadmin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。然而设置了后,发现主题还是默认和bootstrap2,深入跟踪源代码,发现/xadmin/plugins/themes.py下的block_top_navmenu方法,当use_bootswatch为True的时候,就会使用httplib2

解决方案：

安装requests
1
pip install requests

2.在xadmin源码文件夹下的themes.py中引入requests

3.修改block_top_navmenu方法:
`bash
def block_top_navmenu(self, context, nodes):
themes = [
{‘name’: _(u”Default”), ‘description’: _(u”Default bootstrap theme”), ‘css’: self.default_theme},
{‘name’: _(u”Bootstrap2”), ‘description’: _(u”Bootstrap 2.x theme”), ‘css’: self.bootstrap2_theme},
]
select_css = context.get(‘site_theme’, self.default_theme)
if self.user_themes:
themes.extend(self.user_themes)

if self.use_bootswatch:
    ex_themes = cache.get(THEME_CACHE_KEY)
    if ex_themes:
        themes.extend(json.loads(ex_themes))
    else:
        ex_themes = []
        try:
            flag = False
            if flag:
                h = httplib2.Http()
                resp, content = h.request("http://bootswatch.com/api/3.json", 'GET', '',
                                          headers={"Accept": "application/json",
                                                   "User-Agent": self.request.META['HTTP_USER_AGENT']})
