Rails - Apr 2006 - Validation schemes for model objects that are not yet saved

All,

I have a model object that I do a bunch of stuff to before I want to 
save it to the database.  Actually, to be more specific, I do a lot of 
validation that is related to one attribute on this model.  I would like 
to do some validation on it but take advantage of something akin to 
ActiveValidation.

I''ve read through this

http://www.ruby-forum.com/topic/1689#1210

which referenced this:

http://www.realityforge.org/articles/2005/12/02/validations-for-non-activerecord-model-objects

and I just wondered if anyone had come up with another scheme for 
handling validation for "partially constructed" model objects that
they
would be willing to share.

I think I can probably just create another non-database model object to 
handle this validation (since the validation is fairly involved), it 
seems fair to promote this stuff to first-class object status :).

Thanks,
Wes
