反向Django通用视图,post_save_redirect; 错误'包含urlconf没有任何模式'

Question

我确实看到另一个题为"如何使用django反向通用视图"和"django命名网址,通用视图"的问题,但我的问题有点不同,我不相信它是一个骗局.

码:

from django.views.generic import list_detail, create_update
from django.core.urlresolvers import reverse
from django.conf.urls.defaults import *

partners_add = {'form_class': FooForm,
      'post_save_redirect': reverse('foo-list'),
      }


urlpatterns = patterns('',
      url(r'^foo/$', list_detail.object_list, foo_list, name='foo-list'),
      url(r'^foo/add/$', create_update.create_object, foo_add, name='foo-add'),
      )

但是,当我运行代码时,我收到错误"包含的urlconf bar.urls中没有任何模式".然后,当我将反向('foo-list')更改为'/ bar/foo /'时,它可以工作.但是,如果我在模板中调用{%url foo-list%},我会得到正确的URL并且代码可以工作.

添加反向也将破坏相同urlpatterns中具有相同错误的所有URL.

我在Python 2.6上运行Django 1.1

这是我在这里找到的问题的解决方案:http: //andr.in/2009/11/21/calling-reverse-in-django/

我已粘贴下面的代码片段,以防链接消失:

from django.conf.urls.defaults import *
from django.core.urlresolvers import reverse
from django.utils.functional import lazy
from django.http import HttpResponse

reverse_lazy = lazy(reverse, str)

urlpatterns = patterns('',
url(r'^comehere/', lambda request: HttpResponse('Welcome!'), name='comehere'),
url(r'^$', 'django.views.generic.simple.redirect_to',
{'url': reverse_lazy('comehere')}, name='root')
)
