我正在尝试访问详细视图，但它似乎没有正确映射。有什么我想念的吗？当我尝试访问 localhost:8000/polls/1 视图时，我得到一个 404 表示 url 模式与下面给出的任何这些 url 模式都不匹配。我的正则表达式有问题吗？
以下是 404 中的 url 模式：
^polls/ ^$
^polls/ ^polls/(?P<poll_id>\d+)/$
^polls/ ^polls/(?P<poll_id>\d+)/results/$
^polls/ ^polls/(?P<poll_id>\d+)/vote/$
^admin/
当前 URL polls/1/vote/ 与其中任何一个都不匹配。
这是 urls.py：
from django.conf.urls import patterns, include, url
urlpatterns = patterns('polls.views',
url (r'^$', 'index'),
url (r'^polls/(?P<poll_id>\d+)/$', 'detail'),
url (r'^polls/(?P<poll_id>\d+)/results/$', 'results'),
url (r'^polls/(?P<poll_id>\d+)/vote/$', 'vote'),
)
这是我的views.py：
from django.template import RequestContext
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from django.shortcuts import render_to_response, get_object_or_404
from polls.models import Choice,Poll
def index(request):
latest_poll_list = Poll.objects.all().order_by('-pub_date')[:5]
return render_to_response('polls/index.html', {'latest_poll_list': latest_poll_list})
def detail(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
return render_to_response('polls/detail.html', {'poll': p},
context_instance=RequestContext(request))
def results(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
return render_to_response('polls/results.html', {'poll':p})
def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
#Redisplay poll voting form
return render_to_response('polls/detail.html', {
'poll': p,
'error_message': "You didn't select a choice.",
}, context_instance=RequestContext(request))
else:
selected_choice.votes += 1
selected_choice.save()
return HttpResponseRedirect(reverse('polls.views.results', args=(p.id,)))
