Question

我正在尝试对命名包装方法的URL进行反向解析。我在urls.py中设置了以下内容（基于this answer：

urlpatterns = patterns('',
('param_select/$',session_check(param_select),{}, 'param_select'),
('registration/$',registration),
('result_show/(\d+)',session_check(result_show),{}, 'result_show'),
('^expofit/$',media_clean(start),{}, 'start'),
('result_pick/$',session_check(result_pick),{}, 'result_pick'),
('mail_report/$',session_check(mail_report)),
('notification/$',session_check(notification)),

它适用于没有参数的所有方法。然而，在接受参数的那个上失败了。

In [50]: from django.core.urlresolvers import reverse

In [51]: reverse('result_pick')
Out[51]: '/result_pick/'

In [52]: reverse('start')
Out[52]: '/expofit/'

In [53]: reverse('result_show', args=(2,))

    397 
    398 class LocaleRegexURLResolver(RegexURLResolver):

NoReverseMatch: Reverse for 'result_show' with arguments '(2,)' and keyword arguments '{}' not found.

我一直在关注这本书，除了名字url everythong看起来一样。关于缺陷在哪里的想法？

问题在于我使用的是Django 1.4版本，并阅读了Django 1.5文档。更新后，一切正常。

In [5]: reverse('result_show',args=(3,))
Out[5]: '/result_show/3'

使用参数反向命名包装方法的URL
