django，未定义名称'IndexView' [英] django, name 'IndexView' is not defined

问题描述

我正在关注本教程。目前我在这个点，但是当我开始我的服务器与 python manage.py runserver 0.0.0.0:8000 并打开浏览器中的URL，我收到以下错误：

I am following this tutorial. At the moment I am at this point but when I start my server with python manage.py runserver 0.0.0.0:8000 and open the url in my browser, I receive following Error:

name 'IndexView' is not defined

是我的urls.py

This is my 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，因为我从来没有看到自己甚至宣布这个 IndexView 某处。如果你们可以给我一些关于这一点的建议，那将是非常棒的。

I don't know how to solve this problem, since I never saw myself even declaring this IndexView somewhere. It would be awesome if you guys could give me some suggestions on this one.

我的观点.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)

推荐答案

您必须创建 IndexView 并将其导入到您的 urls.py 中。
目前，解释器抱怨，因为在 urls.py IndexView 中是未知的。
要创建新视图，您应该在 views.py 中创建一个新类，如下所示：

You have to create that IndexView and import it in your urls.py. Currently the interpreter complains since in the urls.py IndexView is unknown. To create a new view you should create a new class in views.py, something like:

from django.views.generic.base import TemplateView

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

ps：请阅读官方的Django文档，这是非常好的！

ps: please read the official Django docs, which is very good!
