django

Question

我正在尝试了解基于 class 的视图和一般的 Django。该项目是 notes_project，我在其中创建了一个应用程序 notes。以下是这两个应用程序的 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)),
)

notes/urls.py

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


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

notes/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，我总是收到以下错误：

Request Method: GET
Request URL:    http://127.0.0.1:8000/notes/

patterns 的第一个参数是一个字符串，作为其余模式的前缀。此外，每个模式都需要是自己的元组。您在主 urls.py 中正确地完成了该操作，但在注释一中遗漏了它。应该是：

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

django - 'function' 对象没有属性 'resolve'

django - 'function' object has no attribute 'resolve'
