I was wondering when and why you would use delegate method. So a simple example from the docs.
class User < ActiveRecord::Base has_one :profile delegate :name, :to => :profile end
Ok so now we have a clean way of getting the user profiles name
<%= @user.name %>
But is this a real advantage instead of doing.
<%= @user.profile.name %>
Also by using delegation are we eliminating +1n queries?
