I'm having a problem with using reverse for wrapped methods in Django. Here is my 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)),

I can do a succesfull reverse only for the 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.

Since the situation is the same for all other wrapped methods, and it only works for the one which isn't wrapped, i believe it has something to do with reversing wrapped methods. Ideas for solution?

Just name your urls - ie

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

Then you can use 

reverse('param_select')

Another idea would be to rewrite session_check as a decorator; django's built in view decorators (i.e. permission_required) would make a good starting point.
