django, name 'IndexView' is not defined -

i following this tutorial. @ moment @ this point when start server python manage.py runserver 0.0.0.0:8000 , open url in browser, receive following error:

name 'indexview' not defined 

this urls.py

from django.conf.urls import include, url django.contrib import admin django.conf.urls import patterns  rest_framework_nested import routers authentication.views import accountviewset  router = routers.simplerouter() router.register(r'accounts', accountviewset)  urlpatterns = patterns(     '',     url(r'^admin/', include(admin.site.urls)),      url(r'^api/v1/', include(router.urls)),     url('^.*$', indexview.as_view(), name='index'), ) 

i don't know how solve problem, since never saw myself declaring indexview somewhere. awesome if guys give me suggestions on one.

edit:

my views.py

from django.shortcuts import render  # create views here.  rest_framework import permissions, viewsets  authentication.models import account authentication.permissions import isaccountowner authentication.serializers import accountserializer  class accountviewset(viewsets.modelviewset):     lookup_field = 'username'     queryset = account.objects.all()     serializer_class = accountserializer      def get_permissions(self):         if self.request.method in permissions.safe_methods:             return (permissions.allowany(),)          if self.request.method == 'post':             return (permissions.allowany(),)          return (permissions.isauthenticated(), isaccountowner(),)      def create(self, request):         serializer = self.serializer_class(data=request.data)          if serializer.is_valid():             account.objects.create_user(**serializer.validated_data)              return response(serializer.validated_data, status=status.http_201_created)          return response({             'status': 'bad request',             'message': 'account not created received data.'         }, status = status.http_400_bad_request) 

you have create indexview , import in urls.py. interpreter complains since in urls.py indexview unknown. create new view should create new class in views.py, like:

from django.views.generic.base import templateview  class indexview(templateview):     template_name = 'index.html' 

ps: please read official django docs, good!
