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
