I wonder what is the best way to delete all the records of the association on a specified condition. For example, you have User model that has many Post(s). How would keep all the recent User's Posts and delete all the last Posts when a Users have more than 25 ?
There is a solution like that: def self.delete_old_posts old_posts = [] users = includes(:post) users.each do |user| old_posts =+ user.posts.offset(25) unless user.posts.empty? end old_posts.delete_all end Any other ideas ?
