template {% url } tag syntax

i have a hardwired URL in my template:

/djggApp/guest/{{ guest.guestId }}/update/

that successfully matches against this url pattern:

url(r'^guest/(\d+)/update$', login_required(views.GuestUpdate.as_view()), name='updateGuest'),

now i am trying to replace the template code with a more modern reverse lookup via a url tag:

{% url 'djggApp/guest' guest.guestId 'update'%}

but this generates a NoReverseMatch error

Reverse for 'djggApp/guest' with arguments '(1, u'update')' and keyword arguments '{}' not found. 0 pattern(s) tried: []
