Template Import tab _cookie_ decorator _ _ notes

默认值:
url(r'index/', views.index,{'name':"root"})
def index(request,name):
    print(name)
    return HttpResponse('ok')


命名空间:
/a/   include('app01.urls',namespace='m1')
/b/   include('app01.urls',namespace='mm1')

app01.urls
/index/  name='n1'

reverse('m1:n1')-->对应url /a/index/

命名空间补充:
from django.conf.urls import url,include
urlpatterns = [
    url(r'^a/', include('app01.urls', namespace='author-polls')),
    url(r'^b/', include('app01.urls', namespace='publisher-polls')),

from django.conf.urls import url
from app01 import views
= APP_NAME 'app01'
the urlpatterns = [
    URL (R & lt '? ^ (P <PK> \ + D) / $', views.detail, name = 'Detail')
]

app01.views.py
DEF Detail (Request, PK):
    Print (request.resolver_match)
    return the HttpResponse (PK)

as defined above with a namespace after url, when used to generate the URL name, should be as follows:
V = Reverse ( 'polls-author: Detail', kwargs = { 'PK':. 11} )
{% URL 'polls-author: Detail' PK = PP = 99%} 12 is
