Question

我已经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文件进行民意调查，甚至添加了“详细信息”（这打破了事情）。我还检查了所有__init__.py个文件，它们似乎都属于它们所属的位置。当我在/ Users / apisgirl / mysite / polls / templates / polls中放入一个__init__.py文件时（这是我在这个阶段所做的教程，也就是我正在处理模板的地方）它会破坏一切。所以这是不行的。

目前这是破碎的方式：

我也在使用最新版本的osx（所有更新和什么不是），所以我认为这是我自己的错，我只是在这里错过了一些部分。

我想不出我做过的任何其他事情，我保证检查了settings.py，我的所有urls.py文件，以及我可能错过的任何我的views.py文件。我自然会多次阅读教程，在那里寻找答案。我只是没有得到它。

编辑：这与mysite / polls / urls.py中的这一行有关吗？我已经检查了，这就是教程中的样子。这是一个版本问题吗？

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

根据请求，这是我的polls / views.py文件，它有一些第4部分的代码，因为我开始寻找答案：

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,))),

Answer 1

错误说

'module' object has no attribute 'detail'

和堆栈跟踪显示它出现在这一行：

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（此处“属性”表示“无论你用点符号访问什么“，那就是：变量，函数，方法......等等。”

确实，您的views.py缺少detail功能。检查教程的第3部分its defintion。

Django Tutorial的第3部分 - 'module'对象没有属性'detail'
