我正在尝试对命名包装方法的 URL 进行反向解析。我的 urls.py 中有以下设置（基于此答案：
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)),
它适用于所有没有参数的方法。但是，它在带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,))

我一直在关注这本书，除了命名的 url 之外，一切看起来都一样。关于缺陷在哪里的想法？
