Question

我在Django中使用reverse包装方法时遇到问题。这是我的urls.py

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

我只能为reverse成功registration。

In [37]: from django.core.urlresolvers import reverse
In [38]: from expofit_django_app import views
In [38]: reverse(views.registration)
Out[38]: '/registration/'
In [42]: reverse(views.mail_report)

    397 
    398 class LocaleRegexURLResolver(RegexURLResolver):

NoReverseMatch: Reverse for 'expofit_django_app.views.mail_report' with arguments '()' and keyword arguments '{}' not found.

由于所有其他包装方法的情况相同，并且它仅适用于未包装的方法，我相信它与反转包装方法有关。解决方案的想法？

Answer 1

只需为您的网址命名 - 即

('/param_select/$', session_check(param_select), {}, 'param_select'),

然后你可以使用

reverse('param_select')

另一个想法是将session_check重写为装饰者; django内置的视图装饰器（即permission_required）将成为一个很好的起点。
