10.8Xadmin url注册

2018-10-8 16:45:31

这两天在弄我的服务器,就是是看各种教程 死活部署不好我的Django项目 博客网站

过几天再弄!

越努力,越幸运!永远不要高估自己!

通过两个方法,通过类变量找到字符串和app名字

 url的注册和分发!!

主要看用户怎样访问的!!!  xadmin 采用了面向对象! 两个类互相调用方法!

放上源码,.自己体会

url.py

"""s10day83 URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url
from django.contrib import admin


from Xadmin.service.Xadmin import site
urlpatterns = [
    url(r'^admin/',  admin.site.urls),
    url(r'^Xadmin/', site.urls),　　
　　# url(r'^xx/',  xxx)   xxx部分要么是视图函数,要么得放([], none,none)分发url   正如上面site.urls执行这个方法
　　#  返回的正好是一个元组([], none,none) 所以可以执行

# django 启动的时候这个模块直接被加载,site.urls 是调用静态方法 urls是类里面的静态方法,调用的时候不需要在后面加()

site=XadminSite()

在Django一启动,就构建好了! 每一个分发都构建一个内存空间!
