Question

所以我正在学习Django教程，在page的中间部分，我必须在 mysite \ polls \ views.py

中进行一些更改。

这就是我按照class IndexView和class DetailView进行更改的方式：

mysite的\轮询\ 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\轮询\ urls.py：

from django.conf.urls import url

from . import views

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

AND，这是我得到的错误：（请注意，我的缩进符合预期）

另外，下面的Traceback只有1个测试错误，有6个 SIMILAR TEST ERRORS WITH EXACT TRACEBACK

我尝试搜索此错误，但它要求的是正确缩进代码，它已经是。

Answer 1

也许是因为你将标签与空格混合在一起。

Answer 2

这种情况一直发生在我身上，特别是如果你做任何剪切和粘贴代码。有时你会在标签中找到一个空格，但它仍然“看起来”就像是一样。我建议你设置你的编辑器以使用空格作为标签（我使用四个空格作为标签），然后返回并删除所有的缩进，然后将它们添加回来，你将拥有一致的4个空格/制表符缩进，应该解决你的问题。

Answer 3

字处理器通常用空格替换制表符，但事实并非如此。有时，如果您在同一文档中使用带空格的制表符，则解释程序不喜欢它。

通常，如果发生此错误，则可能会在上面的最后一个间距内以及标记的行中。我建议删除所有空格并将其重做为行。

如果出现相同的错误，则会出现制表符/空格问题，所以只需重做空白直到停止为止。

或者vim可以使用＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;和＆gt;＆gt;在正常模式下。
