Question

我创建了index.html并使用了TemplateView。当我试图访问我的索引时，我得到一个错误，我的索引视图没有定义。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

以下是我的代码：

urls.py

from django.conf.urls import patterns, url

from . import views

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

views.py

from django.views.generic import TemplateView

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

Exception Type: NameError at /
Exception Value: name 'IndexView' is not defined

Answer 1

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

您应该重写您的导入声明 -

from yourapp.views import IndexView

或者重写你的urlconf -

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

也许读过python的命名空间 - 这就是导致NameError异常的原因。

除此之外，您还将视图定义为函数而不是应该是类 -

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

Answer 2

弄清楚我的错误。我将def代替class。

def IndexView(TemplateView): //wrong

class IndexView(TemplateView): //correct

Django 1.5 - 使用TemplateView时找不到定义的视图
