django-'function'对象没有属性'resolve'

Question

我试图学习一般基于类的视图和django。 该项目为notes_project ，在其中创建了一个应用notes 。 以下是这两个文件的urls.py和notes应用程序的views.py ：

notes_project / urls.py

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


urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'notes_project.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^notes/', include('notes.urls')),
    url(r'^grappelli/', include('grappelli.urls')),
    url(r'^admin/', include(admin.site.urls)),
)

笔记/ urls.py

from django.conf.urls import include, patterns, url
from .views import IndexView


urlpatterns = patterns(r'^$/', IndexView.as_view())

笔记/ views.py

from django.shortcuts import render
from django.http import HttpResponse
from django.views.generic import View


class IndexView(View):

    def get(request):
        return HttpResponse("Welcome to notes index")

但是，每当我访问URL http://127.0.0.1:8000/notes/时 ，我都会不断收到以下错误消息：

Request Method: GET

patterns的第一个参数是一个字符串，充当其余模式的前缀。 同样，每个模式都必须是其自己的元组。 您已经在主要的urls.py中正确地做到了这一点，但是在注释一中却错过了。 它应该是：

urlpatterns = patterns('',
    (r'^$', IndexView.as_view()),
)
