反向Django通用视图，post_save_redirect;错误“包含的urlconf没有任何模式” [英] Reverse Django generic view, post_save_redirect; error 'included urlconf doesnt have any patterns'

问题描述

我确实看到了另一个题为如何使用django反向通用视图和 django命名为url，通用视图的问题，但是我的问题有些不同，我不认为这是一个骗子。

I did see the other question titled 'how to use django reverse a generic view' and 'django named urls, generic views' however my question is a little different and I do not believe it is a dupe.

代码：

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，出现错误包含的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，如果在模板中，如果我调用{％url foo-list％}，我将获得正确的url，并且代码可以正常工作。

However when I run the code I get the error "The included urlconf bar.urls doesn't have any patterns in it". Then when I change reverse('foo-list') to '/bar/foo/' it works. If however, within the template if i call {% url foo-list %} I get the correct url and the code works.

添加相反的内容也会破坏所有url

Adding the reverse will also break all urls within the same urlpatterns with the same error.

我正在python 2.6上运行Django 1.1

我有在链接消失的情况下粘贴以下代码段：

I have pasted the code snippet below in case that link disappears:

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')
)
