xadmin的主题use

花匠小妙招

xadmin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

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.

1.安装requests

pip install requests

2.在./xadmin/plugins/themes.py 引入requests

import requests

3.修改block_top_navmenu方法：

# Block Views
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 # 假如为True使用原来的代码，假如为Flase，使用requests库来访问
if flag:
h = httplib2.Http()
resp, content = h.request("https://bootswatch.com/api/3.json", 'GET', '',
headers={"Accept": "application/json", "User-Agent": self.request.META['HTTP_USER_AGENT']})
if six.PY3:
content = content.decode()
watch_themes = json.loads(content)['themes']
else:
content = requests.get("https://bootswatch.com/api/3.json")
if six.PY3:
content = content.text.decode()
watch_themes = json.loads(content.text)['themes']
ex_themes.extend([
{'name': t['name'], 'description': t['description'],
'css': t['cssMin'], 'thumbnail': t['thumbnail']}
for t in watch_themes])
except Exception as e:
print(e)
