python中的"缩进错误:意外缩进"

所以我正在学习Django教程,在页面的中间部分,我必须在mysite\polls\views.py中进行一些更改.

这就是我如何进行更改class IndexView并class DetailView按照要求:

mysite的\调查\ views.py:

class IndexView(generic.ListView):
    template_name = 'polls/index.html'
    context_object_name = 'latest_question_list'

    def get_queryset(self):
        """
        Return the last five published questions (not including those set to be
        published in the future).
        """
        return Question.objects.filter(
        pub_date__lte=timezone.now()
        ).order_by('-pub_date')[:5]

class DetailView(generic.DetailView):
    model = Question
    template_name = 'polls/detail.html'

    def get_queryset(self): #The Error Points Here
        """
        Excludes any questions that aren't published yet.
        """
        return Question.objects.filter(pub_date__lte=timezone.now())

mysite的\调查\ urls.py:

from django.conf.urls import url

from . import views

app_name = 'polls'
urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P[0-9]+)/$', views.DetailView.as_view(), name='detail'),
    url(r'^(?P[0-9]+)/results/$', views.ResultsView.as_view(), name='results'),
    url(r'^(?P[0-9]+)/vote/$', views.vote, name='vote'),
    ]

AND,这是我得到的错误:( 请注意,我的缩进是正确的,如预期的那样)

另外,下面的Traceback只有1个测试错误,有6个类似的测试错误,带有精确的跟踪

我尝试搜索这个错误,但它要求的是正确缩进代码,它已经是.

也许是因为你将标签与空格混合在一起.
