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
xadmin
xadmin 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:
#coding:utf-8
from __future__ import print_function
import httplib2
from django.template import loader
from django.core.cache import cache
from django.utils import six
from django.utils.translation import ugettext as _
from xadmin.sites import site
from xadmin.models import UserSettings
from xadmin.views import BaseAdminPlugin, BaseAdminView
from xadmin.util import static, json
import six
if six.PY2:
import urllib
else:
import urllib.parse
import requests
THEME_CACHE_KEY = 'xadmin_themes'
class ThemePlugin(BaseAdminPlugin):
enable_themes = False
# {'name': 'Blank Theme', 'description': '...', 'css': 'http://...', 'thumbnail': '...'}
user_themes = None
use_bootswatch = False
default_theme = static('xadmin/css/themes/bootstrap-xadmin.css')
bootstrap2_theme = static('xadmin/css/themes/bootstrap-theme.css')
def init_request(self, *args, **kwargs):
return self.enable_themes
def _get_theme(self):
if self.user:
try:
return UserSettings.objects.get(user=self.user, key="site-theme").value
except Exception:
pass
if '_theme' in self.request.COOKIES:
if six.PY2:
func = urllib.unquote
else:
func = urllib.parse.unquote
return func(self.request.COOKIES['_theme'])
return self.default_theme
def get_context(self, context):
context['site_theme'] = self._get_theme()
return context
# Media
def get_media(self, media):
return media + self.vendor('jquery-ui-effect.js', 'xadmin.plugin.themes.js')
# 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:
# 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']
# ex_themes.extend([
# {'name': t['name'], 'description': t['description'],
# 'css': t['cssMin'], 'thumbnail': t['thumbnail']}
# for t in watch_themes])
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("http://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)
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。
