# 注意httplib2高版本0.10.3
class  BaseSetting(object):
    enable_themes = True
    use_bootswatch = True

xadmin.site.register(views.BaseAdminView,BaseSetting)

修改全局变量

class GlobalSetting(object):

    site_footer='自己的'
　　menu_style='accordion'

xadmin.site.register(views.CommAdminView,GlobalSetting)

去掉项目英文标题
在apps中设置

class UsersConfig(AppConfig):
    name = 'users'
    verbose_name = '用户'
在__init__中设置

default_app_config = 'users.apps.UsersConfig'

在设置跳转页面

from django.views.generic import TemplateView
urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
    url(r'^$', TemplateView.as_view(template_name='xx.html'),name='xxx'),

redirect('/home/')    # 重定向  打开新页面

render(request,'login.html',{'msg':msg})#页面渲染


用户登录 方法1

views中

# -*- coding: utf-8 -*-
from django.shortcuts import render

from django.contrib.auth import  authenticate,login,logout
from  django.contrib.auth.backends import ModelBackend
from .models import UserFile
from django.db.models import Q
# Create your views here.

        else:
            return render(request, 'index.html', {'login_form':login_form})
退出:

from django.contrib.auth import  authenticate,login,logout
