Django 1.5 - Cannot find the defined view when using TemplateView -

I am creating index.html and I use TemplateView. When I'm trying to use my index, I get an error that my index view is not defined. I do not know why, I follow this method

These are my codes:

urls.py

  Import pattern from Django.conf.urls, import view urlpatterns = pattern ('', url (r '^ $', views.IndexView.as_view (), name = 'index') from url)  <   Traceback  
  views.py from Template: Strong>   (updated)

 You are getting an error because you have not imported the  IndexView  in the current namespace, you have imported  view   IndexView  Only  views  namespace - i.e.  views.indexview .  
 is accessible within, you should rewrite your import details -  
  see yourapp.views import index   
 Or rewrite your urlconf -  
  urlpatterns = pattern ('', url (r '^ $', views.IndexView.as_view (), name = 'index'),)   
 It may be that Python's name is read in place - this is what your  NameError  is the exception.  
 On that, you have defined your view as a function rather than that class -  
  class indexview (TemplateView):  instead of  Def Definitive View (TemplateView):
