hi maybe its a simple question, but i can't understand how to resolve it. i have a model user and contact. so a user can have many contact and contact belong to one user. so for now i want count the number of contact of the user. what i did is like this: count = ActiveRecord::Base.connection.select_one("select count(person_id) amis from contacts where user_id =" + user.id.to_s)
but i dont like this solutions cause the number of freind i will use it in a sortable table, and if this variable dont belong to the user params, i cant use it to sort the table thanks.
