both auto_now and auto_now_add are quite hackish little puppies. auto_now should really be equivalent to a _pre_save that sets the field to the current time.
auto_now_add should really be equivalent to a non-editable field that gets set to the current time on insert, and is just statically displayed afterwards. So to get these working 'well', I think we need : * the event framework for fields to add handlers to (just like ImageField, FileField etc. ) I will probably hack this up as just lists of callbacks for now, but I would still prefer a real event system. * the ability for FormFields to be replaced by static versions, eg allowing special things to be put in the follow argument of the manipulator, maybe a constant or even a FormField class. This could alternatively be hacked around by making TimeField,DateTimeField and DateField return different FormFields when auto_now_add is true.
