python - Template url, number with 'L' -

i've got next code in template:

{% url "app.views.details" d.id %}

normally works good, have problem in end of id 'l', i'm getting exception:

reverse 'app.views.details' arguments '(4l,)' , keyword arguments '{}' not found.

what wrong id now?

edit: here url.conf:

url(r'^detailed-stats/(?p<id>\d+)/', 'app.views.details', name='details'),

long numbers works \d+ pattern, seek utilize name param of route instead:

{% url "details" id=d.id %}
