django-include函数

三种格式：
（1）incude(module,namespace=None)

from django.urls import path,include
from book import urls
urlpatterns={
  path('',include(urls))                
}

module：模型文件，namespace：实例命名空间

（2）include(pattern_list)

from django.urls import path,include
from . import views
extractpatterns={
  path('',views.index,name='index') ,
  path('index/',views.index,name='index'),   
  path(''home/,views.index,name='index'), 
}
urlpatterns={
  path('index/',include(extracpatterns),name='index')                
}

pattern_list：可迭代的path()或re_path()清单

（3）include((pattern_list,app_namespace),namespace)

app_namespace：app命名空间

from django.urls import path,include
from . import views
extractpatterns={
  path('',views.index,name='index') ,
  path('index/',views.index,name='index')   
  path(''home/,views.index,name='index') 
}
urlpatterns={
  path('index/',include((extracpatterns,'newsapp')),name='index')                
}
