Ok, this is what I got from where I'm up to in my learn-djshell-quickly:

>>> s = Session.objects.filter(slug='mechanical-tools-morning-2').get(date=datetime.date.today)
>>> s.session_number
u'1'
>>> s.date
datetime.date(2012, 9, 14)
>>> s.slug
u'mechanical-tools-morning-2'
>>> s.get_absolute_url()

How do I call reverse in the shell? Import it and...?

reverse(s)?

cheers
