Django属性错误.'module'对象没有属性'rindex'

Question

我刚开始使用django,只在网上书的第3章.

当我尝试访问该网站时,我继续遇到这个奇怪的错误.

/ test /'module'对象的AttributeError没有属性'rindex'

我的urls.py只是

from django.conf.urls.defaults import *
from mysite import hello
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
      ('^test/$',hello),
)

我的hello功能很神秘.Python路径是

['/home/james/django/mysite', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/local/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/pymodules/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.6/gtk-2.0', '/home/james/django']

我真的不明白这里发生了什么.我假设我忽视了一些愚蠢的东西,因为它看起来很简单.当我在python解释器中使用mysite import hello时,它不会引发任何错误.

任何帮助都会很棒

你好的功能是

from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello world")

Answer 1

你可能需要改变

from mysite import hello

喜欢的东西

from mysite.hello_file import hello_view

然后使用:

('^test/$',hello_view)

因为您需要传递(视图)函数,而不是文件或模块.我认为mgalgs试图解释,但我认为初学者有点不清楚.

Answer 2

通过以下方式添加基于类的视图时出现此错误：

url(r'^tv/$', views.MyTemplateView(), name='my_tv'),

当然.as_view()应该添加来修复错误object has no attribute 'rindex'：

url(r'^tv/$', views.MyTemplateView.as_view(), name='my_tv'),
