Django urlpatterns가 일치하지 않습니다

Question

일치하지 않는 url 패턴이 있습니다. 이것은 내가 장고 튜토리얼에서 채택한 것이다. 아마 쉬운 일이지만, 나는 그것을 놓치고 있습니다.

오류 :

Page not found (404) 
    Request Method: GET 
    Request URL: http://127.0.0.1:8000/sendemail/1 
Using the URLconf defined in emailme.urls, Django tried these URL patterns, in this order: 
    1. ^sendemail ^$ [name='index'] 
    2. ^sendemail ^(?P<msg_id>\d+)/$ [name='detail'] 
    3. ^sendemail ^(?P<msg_id>\d+)/results/$ [name='results'] 
    4. ^admin/ 
The current URL, sendemail/1, didn't match any of these. 

models.py :

from django.db import models 

class Choice(models.Model): 
    choice_text = models.CharField(max_length=200) 

    def __unicode__(self): 
     return self.choice_text 

루트 urls.py :

from django.conf.urls import patterns, include, url 

# Uncomment the next two lines to enable the admin: 
from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
    url(r'^sendemail', include('sendemail.urls')), 
    # Uncomment the next line to enable the admin: 
    url(r'^admin/', include(admin.site.urls)), 
) 

urls.py :

from django.conf.urls import patterns, url 
from sendemail import views 

urlpatterns = patterns('', 
    url(r'^$', views.index, name='index'), 
    url(r'^(?P<msg_id>\d+)/$', views.detail, name='detail'), 
    url(r'^(?P<msg_id>\d+)/results/$', views.results, name='results')) 

views.py :

from django.http import HttpResponse 

def index(request): 
    return HttpResponse("You're at the index") 

def detail(request, msg_id): 
    return HttpResponse("The details of message id %s" % msg_id) 

def results(request, msg_id): 
    return HttpResponse("The results of message id %s" % msg_id) 

Answer 1

이 패턴에는 후행 슬래시가 필요합니다.

url(r'^(?P<msg_id>\d+)/$', views.detail, name='detail'), 

사용중인 URL에 sendemail/1이 없습니다.
