Rails - Jan 2008 - validating linked ActiveRecords without saving them in DB

I would like to create new records

@user =  User.new(params[:user])
@activity = Activity.new(params[:activity])
....

then validating them without saving to the DB... (as saving one depend
upon saving others..)

or should I use a transaction with rollback ?o
or
use validates_associated ..

or both .. or ?

thanks

kad

User validates_associated :activity.

   @user = User.new(params[:user])
   @user.build_activity(params[:activity])
   if @user.save # saves both, runs in a transaction
     ...
   end
