My best idea is to
posts = Post.find(:all)
sorted_posts = post.sort_by { |post| post.rating }.reverse
highest_rated_post = sorted_posts.first
There''s gotta be a better way though.

Well you could iterate through them all one at a time. if current_highest_post.rating > next_post.rating else move on to the next one.

thanks josh. works like a charm. a general question of database retieval efficiency. if my database starts to get really large, how will find(:all) searches impact on this. ie. will they start to bottledown my application. should i always be restricting finds, like so: posts=Post.find(:all, :order => ''visit_count DESC'', :limit=>200) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

look at the sql queries it uses and then write your own that mimics them.
