django，名称 'IndexView' 未定义

Question

我正在关注 this tutorial. At the moment I am at this 点，但是当我使用 python manage.py runserver 0.0.0.0:8000 启动我的服务器并在我的浏览器中打开 url 时，我收到以下错误：

name 'IndexView' is not defined

这是我的urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.conf.urls import patterns

from rest_framework_nested import routers
from 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'),
)

我不知道如何解决这个问题，因为我什至从未见过自己在某处声明这个 IndexView。如果你们能给我一些关于这方面的建议，那就太好了。

编辑：

我的views.py

from django.shortcuts import render

# Create your views here.

from rest_framework import permissions, viewsets

from authentication.models import Account
from authentication.permissions import IsAccountOwner
from 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 could not be created with received data.'
        }, status = status.HTTP_400_BAD_REQUEST)

Answer 1

您必须创建 IndexView 并将其导入您的 urls.py。目前口译员抱怨，因为在 urls.py IndexView 中是未知的。要创建新视图，您应该在 views.py 中创建一个新的 class，例如：

from django.views.generic.base import TemplateView

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

ps：请阅读Django官方文档，非常好！

Answer 2

在你的 urls.py

from .views import IndexView
url('^.*$', IndexView.as_view(), name='index'),

(.views 或 yourProject.views)

在你的 views.py 做 daveoncode 写的

Answer 3

IndexView class 在样板项目的视图文件中。

C:\...\thinkster-django-angular-boilerplate-release\thinkster_django_angular_boilerplate\views

将该内容复制并粘贴到项目的视图文件中。

from django.views.decorators.csrf import ensure_csrf_cookie
from django.views.generic.base import TemplateView
from django.utils.decorators import method_decorator

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

    @method_decorator(ensure_csrf_cookie)
    def dispatch(self, *args, **kwargs):
        return super(IndexView, self).dispatch(*args, **kwargs)
