Rails - Mar 2006 - transaction question

How does one set up a transaction for multiple models?  For example, how 
do you wrap the entire logic below in one transaction?

#begin transaction
for bar in foo.bars
  bar.something += 1
  bar.save
end

foo.something += 1
foo.save
#end transaction

For even more complexity, what if a mail notification is sent for each 
bar modified in the collection?

thanks,
Jeff

Can you do:

Bar.transaction
  foo.bars.each do |bar|
    bar.something += 1
    bar.save
  end
end

I want the change to foo wrapped in the same transaction.  I don''t
think
you can stick that in Bar.transaction?

Hi Tom,

    How do you do it ? Jonny''s example seems vague... I need both model
to be save!

Thanks.
