Django urls 路由

• 写url和视图的的对应关系
  from django.conf.urls import url
  from django.contrib import admin
  from app名 import views
  urlpatterns = [

  # FBV 写法
  url(r'^admin/', admin.site.urls), # admin 后台管理
  # 对应 视图中的函数
  url(r'login/', views.login, name='login'),
  # 正则分组
  url(r'del_(student|teacher|class)/(\d+)/', views.delete, name='del'),
  # 正则命名分组
  url(r'^data/(?P

     # name='login'  url命名  用于 地址的反向解析

  # CBV 写法
  # 在views.py文件中 写一个类 继承 View 其中写 get post 方法
  # 导入方法from django.views import View
  url(r'index/', views.类名.as_view(), name='index'),

  ]

• url路由分发
  from django.conf.urls import url, include
  from django.contrib import admin
  from crm import views

  urlpatterns = [
      url(r'^admin/', admin.site.urls),
  
      url(r'^show/', include('app名.urls文件名', namespace='show')),
      # namespace='show' 命名空间 
  ]
