Question

我试图了解基于类的视图和django。该项目为notes_project，其中我创建了一个应用notes。以下是这两个urls.py和views.py应用的notes：

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)),
)

备注/ urls.py

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


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

备注/ 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，每当我访问网址http://127.0.0.1:8000/notes/时，我都会收到以下错误：

patterns的第一个参数是一个字符串，作为其余模式的前缀。每个模式也需要是它自己的元组。你已经在主urls.py中正确地完成了这一点，但在笔记一中错过了它。它应该是：

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

django - ＆＃39;功能＆＃39;对象没有属性＆＃39; resolve＆＃39;
