include

Is it possible to limit an AR :include to say only pull in one record...

Item.find(:all,
    :include => [ :external_ratings, :photos => LIMIT 1 ])

I have a list of items and each item has between 5 and 15 photos. I want to load a photo id into memory, but i don't need all of them, I just want to preview the first one.

Is there a way to do this?
