我查看了其他人在类似情况下所做的事情，我在 INSTALLED_APPS 中检查了我的 settings.py 文件以进行民意调查，甚至添加了“详细信息”（这破坏了事情）。我还检查了我所有的__init__.py文件，它们似乎都在它们所属的地方。当我放一个__init__.py文件放入 /Users/apisgirl/mysite/polls/templates/polls （这是本教程建议我在此阶段执行的操作，也是我正在处理模板的地方）时，它会破坏一切。所以这是不行的。

目前情况是这样的：

Environment:


Request Method: GET
Request URL: http://localhost:8000/polls/

Exception Type: AttributeError at /polls/

我也在使用最新版本的 osx（所有更新和什么都没有），所以我认为这是我自己的错，我只是在这里遗漏了一些部分。

我想不出我做过的任何其他事情，我确保检查了 settings.py、我所有的 urls.py 文件和我的views.py 文件以查找我可能遗漏的任何内容。我很自然地已经阅读了很多次教程，在那里寻找答案。我只是不明白。

编辑：这与 mysite/polls/urls.py 中的这一行有关吗？我已经检查过了，这就是教程中的样子。那么这是版本问题吗？

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

在请求这里是我的 polls/views.py 文件，它有一些来自第 4 部分的代码，因为我开始期待答案： 

from django.http import HttpResponse
from django.http import HttpResponse
from django.template import Context, loader

from polls.models import Poll

def index(request):
    latest_poll_list = Poll.objects.order_by('-pub_date')[:5]
    template = loader.get_template('polls/index.html')
    context = Context({
                      'latest_poll_list': latest_poll_list,
                      })
    return HttpResponse(template.render(context))


def results(request, poll_id):
    poll = get_object_or_404(Poll, pk=poll_id)
    return render(request, 'polls/results.html', {'poll': 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):
        # Redisplay the poll voting form.
        return render(request, 'polls/detail.html', {
                      'poll': p,
                      'error_message': "You didn't select a choice.",
                      })
    else:
        selected_choice.votes += 1
        selected_choice.save()
        # Always return an HttpResponseRedirect after successfully dealing
        # with POST data. This prevents data from being posted twice if a
        # user hits the Back button.
        return HttpResponseRedirect(reverse('polls:results', args=(p.id,))),

错误说

'module' object has no attribute 'detail'

并且堆栈跟踪显示它发生在这一行：

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

很明显，解释器试图告诉我们views模块（对应于您的views.py文件）没有属性detail（这里“属性”的意思是“您使用点符号访问的任何内容”，即：变量、函数、方法、 …任何）。

确实，您views.py缺少该detail功能。检查教程的第 3 部分以了解其定义。
