python - How to set up django-siteree with django-postman -

i'm trying set django-sitetree work django-postman, i'm not having luck.

most of pages work correctly, can't seem figure out how map postman_view url work properly. here's have far. maybe can me out bit?

sitetrees.py

from sitetree.utils import tree, item  sitetrees = (     tree('postman', items=[         item('messages', '/messages/', url_as_pattern=false, access_guest=false, access_loggedin=true, children=[             item('compose', 'postman_write', access_guest=false, access_loggedin=true),             item('inbox', 'postman_inbox', access_guest=false, access_loggedin=true),             item('view', 'postman_view message.id', access_guest=false, access_loggedin=true, in_menu=false, in_sitetree=false)         ])     ]) ) 

postman urls.py excerpt

urlpatterns = patterns('',                                                           url(r'^inbox/(?:(?p<option>'+options+')/)?$', inboxview.as_view(), name='postman_inbox'),     url(r'^sent/(?:(?p<option>'+options+')/)?$', sentview.as_view(), name='postman_sent'),     url(r'^archives/(?:(?p<option>'+options+')/)?$', archivesview.as_view(), name='postman_archives'),     url(r'^trash/(?:(?p<option>'+options+')/)?$', trashview.as_view(), name='postman_trash'),     url(r'^write/(?:(?p<recipients>[^/#]+)/)?$', writeview.as_view(), name='postman_write'),     url(r'^reply/(?p<message_id>[\d]+)/$', replyview.as_view(), name='postman_reply'),     url(r'^view/(?p<message_id>[\d]+)/$', messageview.as_view(), name='postman_view'),     url(r'^view/t/(?p<thread_id>[\d]+)/$', conversationview.as_view(), name='postman_view_conversation'),     url(r'^archive/$', archiveview.as_view(), name='postman_archive'),               url(r'^delete/$', deleteview.as_view(), name='postman_delete'),                  url(r'^undelete/$', undeleteview.as_view(), name='postman_undelete'),               (r'^$', redirectview.as_view(url='inbox/')),                                 ) 

both postman_write , postman_inbox work fine, when visit postman_view error:

sitetreeerror @ /messages/view/2/  unable resolve current sitetree item `title_resolved` current page. check whether there appropriate sitetree item defined current url. 

thanks idle sign pointing me in right direction.

turns out postman/view.html template not have variable called message, had assumed. there array of messages called pm_messages. corrected sitetrees.py is:

sitetrees = (     tree('postman', items=[         item('messages', '/messages/', url_as_pattern=false, access_guest=false, access_loggedin=true, children=[             item('compose', 'postman_write', access_guest=false, access_loggedin=true),             item('inbox', 'postman_inbox', access_guest=false, access_loggedin=true),             item('view', 'postman_view pm_messages.0.id', access_guest=false, access_loggedin=true, in_menu=false, in_sitetree=false)         ])     ]) )
