我是 django 新手,我完成了 djangoproject.com 上的 4 部分教程
我的问题是我想在我的投票应用程序上进行登录身份验证。我使用了装饰器@login_required,它工作正常,但在我的views.py 下我只有 vote() 方法。
我在“投票文件夹”下的views.py
from django.shortcuts import render_to_response, get_object_or_404
from django.http import HttpResponseRedirect, HttpResponse
from django.contrib.auth.decorators import login_required
from django.views.decorators.cache import never_cache
from django.core.urlresolvers import reverse
from django.template import RequestContext
from polls.models import Poll, Choice
@login_required
@never_cache
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,)))
return HttpResponse("You're voting on poll %s." % poll_id)
我在“投票文件夹”下的 urls.py
from django.conf.urls.defaults import patterns, include, url
from django.views.generic import DetailView, ListView
from polls.models import Poll
urlpatterns = patterns('',
url(r'^$',
ListView.as_view(
queryset = Poll.objects.order_by('-pub_date')[:5],
context_object_name = 'latest_poll_list',
template_name = 'polls/index.html'), name='poll_lists'),
url(r'^(?P<pk>\d+)/$',
DetailView.as_view(
model = Poll,
template_name = 'polls/detail.html'), name='poll_details'),
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'),
)
在我的 urls.py 下,我使用了通用视图。
问题是:我将如何将登录要求放在民意调查应用程序的“索引”下。以便用户在查看可用投票之前先登录。
当前是:我在views.py和方法vote()下使用了需要登录,投票后需要登录。
任何人都可以帮助我吗?
谢谢,贾斯汀
