python - Django 错误中关于 Page 的顶级信息

Question

我想在我的 Django 站点中有一个顶级 about 页面(例如:http://127.0.0.1:8000/about)，它指向基于 about View 的类民意调查应用程序或顶级关于页面，但是我得到:

TypeError at /about/
__init__() takes 1 positional argument but 2 were given

MySite/Mysite/urls.py:

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

urlpatterns = [
    # Examples:
    url(r'^$', 'myPollSite.views.index', name='myPollSite_home'),
    url(r'^about/$', 'myPollSite.views.AboutView', name='myPollSite_about'),
    url(r'^polls/', include('polls.urls', namespace = "polls")),
    url(r'^admin/', include(admin.site.urls)),

]

MySite/Mysite/views.py:

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

class AboutView(generic.TemplateView):
    template_name = "polls/about.html"


def index(request):
    return HttpResponse("Hello, world. You're at myPollSite index.")

MySite/polls/template/polls/about.html:

<h1>About Page</h1>
<h2>Implemented with TemplateView</h2>
<p>
    No Model Data can be retrieved with Template View
</p>

Answer 1

按照 documentation 中的建议，使用 as_view() 调用配置基于类的 View :

url(r'^about/$', AboutView.as_view(), name='myPollSite_about'),

应导入 AboutView 的位置:

from myPollSite.views import AboutView
