Not very efficient, but you could do: @users.each do |user| user.games.count end Or in your controller you could do... @game_counts = Game.count(:group => :user_id) And then do the necessary lookup in the view to match them up. Or you could add a "games_count" field to the user model and use the :counter_cache option on the relationship so you could do: @users.each do |user| user.games_count end If you're going to be showing this a lot, I'd go with the latter. -philip -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
