saving

Hi.

I get a model object, change an attribute, save it and it still has the old attribute:

>>> g = SiteProfile.objects.get(pk=3)
>>> g.renew_date
datetime.date(2010, 4, 11)
>>> g.renew_date = date.today()+timedelta(days=365)
>>> g.renew_date
datetime.date(2011, 4, 11)
>>> g.save()
>>> g.renew_date
datetime.datetime(2010, 4, 11, 16, 57, 4, 192684)

Anyone know if this is an issue with the database or something else?
