Rails - Jan 2006 - Stopping a save from the before_save

What''s the better thing to do in a before_save if you don''t
want the
save to continue?

raise an exception, or do an errors.add or both?

Thanks,

Return false.

"If a before_* callback returns false, all the later callbacks and  
the associated action are cancelled. If an after_* callback returns  
false, all the later callbacks are cancelled. Callbacks are generally  
run in the order they are defined, with the exception of callbacks  
defined as methods on the model, which are called last." [1]

Does that mean that raising an exception in a callback doesn''t cancel  
later callbacks?

When returning false, how do you detect which callback return false?
