django-sitetree (0.9.4) won't render some menu and breadcrumbs elements

Question

I have a problem with URL Patterns in SiteTree configuration. I have read the manual: https://django-sitetree.readthedocs.org/ru/latest/quickstart.html

So I'm trying to make my tree with named URLs:

1. app/urls.py:

   urlpatterns = patterns('',
   .....
   url('^dict/persons/(?P<person_id>\d+)/$', persondetail, name = 'persondetail'),
   .....
   )
   

2. SiteTree Item config:

   Title: 'Person detail'
   URL: 'app:persondetail person.id'
   

3. URL as Pattern (checked)

The result is bad - SiteTree menu does not work propetly - it doesn't render menu elements and breadscrumbs. On other pages it works.

Also I have tried to write URl pattern like:

    - 'app:persondetail person.id'
    - 'app:persondetail person_id'
    - 'app:persondetail Person.id'
    - 'app:persondetail Person_id'
    - 'app:persondetail {{person.id}}'
    - 'app:persondetail {{Person.id}}'
    - 'app:persondetail #person.id'
    - 'app:persondetail #Person.id'
    - with quotes and without

But it doesn't still work.

Structure of my project is:

  |       from django.conf.urls import patterns, include, url
  |       from django.contrib import admin

  |       urlpatterns = patterns('',

      |   .....

      |   .....

      |___views.py:

          def persondetail(request, person_id):
              pers = get_object_or_404(Person, pk=person_id)
              return render(request, 'app/persDetail.html', {'pers': pers})
          .....

Answer 1

render(request, 'app/persDetail.html', {'pers': pers})

You're passing pers variable into your template, so you should tell exactly that to sitetree. Instead of app:persondetail person.id type — app:persondetail pers.id

The string put into sitetree URL field is essentially the same you'd use with url template tag, e.g.: {% url 'app:persondetail' pers.id %}.
