我创建 index.html 并使用 TemplateView。当我尝试访问我的索引时，我收到一个错误，即我的索引视图未定义。我不知道为什么，我只是遵循这种模式 https://docs.djangoproject.com/en/dev/topics/class-based-views/#subclassing-generic-views

这是我的代码：

网址.py

from django.conf.urls import patterns, url

from . import views

urlpatterns = patterns('',
    url(
        r'^$', 
        views.IndexView.as_view(),
        name='index'
    ),
)

视图.py

from django.views.generic import TemplateView

def IndexView(TemplateView):
    template_name = 'index.html'

您收到错误是因为您尚未导入IndexView当前命名空间。您已导入views. IndexView只能在views命名空间内访问 - 即views.IndexView.

你应该重写你的导入语句 -

from yourapp.views import IndexView

或者重新编写你的 urlconf -

urlpatterns = patterns(' ',
   url(r'^$', views.IndexView.as_view(), name='index'), 
)

也许阅读 python 的命名空间 - 这就是导致您的NameError异常的原因。

最重要的是，您还将视图定义为一个函数，而不是它应该是的类 -

class IndexView(TemplateView):而不是def IndexView(TemplateView):

只要弄清楚我的错误。我把def而不是class.

def IndexView(TemplateView): //wrong

class IndexView(TemplateView): //correct
