I've read in rails api that there is a touch parameter and I want to
use it in my application. I have something like that
class User < ActiveRecord::Base
class Phone < ActiveRecord::Base
belongs_to :user, :touch => true
I want that every change of any phone number would change User
updated_at and also call user after_update callback.
But when I add :touch parameter I get error that looks like:
ArgumentError: Unknown key(s): touch
from (eval):3:in `belongs_to'
