回复： Stuck on "ViewDoesNotExist" last step of tutorial part 4

there's no function in views.py, you should define that 'index' handler

I've having a similar problem here using Django 1.4 and I can't quite figure what's wrong. The error reads: Could not import polls.views.index. View does not exist in module polls.views.

urls.py

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

from django.views.generic import DetailView, ListView

from polls.models import Poll

Uncomment the next two lines to enable the admin:

from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',

url(r'^$',

ListView.as_view(

queryset = Poll.objects.order_by('-pub_date')[:5],

context_object_name = 'latest_poll_list',

template_name = 'polls/index.html')),

url(r'^(?P<pk>\d+)/$',

DetailView.as_view(

model = Poll,

template_name = 'polls/detail.html')),

url(r'^(?P<pk>\d+)/results/$',

DetailView.as_view(

model = Poll,

template_name = 'polls/results.html'),

name='poll_results'),

url(r'^(?P<poll_id>\d+)/vote/$', 'polls.views.vote'),

)

urlpatterns = patterns('',

url(r'^polls/', include('polls.urls')),

url(r'^admin/', include(admin.site.urls)),

)

# Uncomment the admin/doc line below to enable admin documentation:

# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

views.py

# Create your views here.

from django.shortcuts import render_to_response, get_object_or_404

from django.http import HttpResponseRedirect, HttpResponse

from django.core.urlresolvers import reverse

from django.template import RequestContext

from polls.models import Choice, Poll

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):

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('poll_results', args = (p.id,)))
