我正在关注“https://docs.djangoproject.com/en/1.5/intro/tutorial04/”
中提供的教程在将通用视图代码应用于'polls / urls.py'之前,一切正常。现在我在webbrowser窗口中出现以下错误:
@ index.py
@ detail.py
我已经阅读了问题并回答了@'Django official tutorial for the absolute beginner, absolutely failed!',现在更加困惑了。这是指教程文档的一部分,并建议:
“浏览模板,修改对latest_poll_list到object_list的任何引用,并将对poll的任何引用更改为object。”
但是,我使用的教程文档的版本似乎表明可以通过设置来方便地避免这种情况:
context_object_name='latest_poll_list'
我的民意调查/ urls.py目前看起来像这样:
from django.conf.urls import patterns, url
from django.views.generic import DetailView, ListView
from polls.models import Poll
from polls import views
urlpatterns=patterns(' ',
# ex: /polls/
url(r'^$',
ListView.as_view(
queryset=Poll.objects.order_by('-pub_date')[:5],
context_object_name='latest_poll_list',
template_name='polls/index.html'),
name='index'),
# ex: /polls/5/
url(r'^(?P<pk>\d+)/$',
DetailView.as_view(
model=Poll,
template_name='polls/detail.html'),
name='detail'),
# ex:/polls/5/results/
url(r'^(?P<pk>\d+)/results/$',
DetailView.as_view(
model=Poll,
template_name='polls/results.html'),
name='results'),
# ex: /polls/5/vote/
url(r'^(?P<poll_id>\d+)/vote/$','polls.views.vote',name='vote'),
)
我的民意调查/ views.py看起来像这样:
from django.http import Http404, HttpResponseRedirect
from django.template import Context, loader
from django.shortcuts import render, render_to_response, get_object_or_404
from django.core.urlresolvers import reverse
from polls.models import Poll, Choice
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(request, 'polls/detail.html',{
'poll':p,
'error_message': "You didn't select a choice.",
})
else:
selected_choice.votes+=1
selected_choice.save()
return HttpResponseRedirect(reverse('polls:results',args=(p.id,)))
这是我错过的拼写错误还是我确实需要更改HTML文件中的引用?非常感谢所有的建议。
答案 0 :(得分:0)
您是否将命名空间添加到根urls.py?
url(r'^polls/', include('polls.urls', namespace="polls")),
修改强> 尝试将patterns调用中的space参数更改为空字符串:
urlpatterns=patterns(' ',
到
urlpatterns=patterns('',
