Django的路由系统01-路由分发

1. Including other URLconfs

原urls.py文件，多个app的路由系统写在一起，不方便管理

范例：

from django.conf.urls import url
from django.contrib import admin
from app01 import views
from app02 import views as app02_views
 
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^publisher_list/$', views.PubList.as_view()),
    url(r'^edit_publisher/$', views.EditPub.as_view()),
    url(r'^book_list/$', views.BookList.as_view()),
    url(r'^templates/$', views.Templates.as_view()),
    url(r'^book/$', app02_views.book),
]

2. 使用include

使用：

2.1 注释app01的相关配置

from django.conf.urls import url
from django.contrib import admin
 
from app02 import views as app02_views
 
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # url(r'^publisher_list/$', views.PubList.as_view()),
    # url(r'^edit_publisher/$', views.EditPub.as_view()),
    # url(r'^book_list/$', views.BookList.as_view()),
    # url(r'^templates/$', views.Templates.as_view()),
    url(r'^book/$', app02_views.book),
]

2.2 在app01目录中创建urls.py文件

from django.conf.urls import url
from app01 import views
 
urlpatterns = [
    url(r'^publisher_list/$', views.PubList.as_view()),
    url(r'^edit_publisher/$', views.EditPub.as_view()),
    url(r'^book_list/$', views.BookList.as_view()),
    url(r'^templates/$', views.Templates.as_view()),
]

但是仅此而已还不够，启动Django项目，发现不能访问app01中的链接

2.3 导入urls模块的include方法

方法一：

from django.conf.urls import url, include
from django.contrib import admin
from app02 import views as app02_views
 
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # 这种方式不明确，不能根据程序区分
    url(r'^', include('app01.urls')),
    url(r'^book/$', app02_views.book),
]

方法二：

from django.conf.urls import url, include
from django.contrib import admin
from app02 import views as app02_views
 
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # 这种方式可以根据不同的程序访问不同的url
    url(r'^app01/', include('app01.urls')),
    url(r'^book/$', app02_views.book),
]
