ruby on rails - Inject data members to an object -

this question based on another question of mine(thankfully answered).

so if in model have this:

def self.find_extended     person = person.find(:first)     complete_name = person.firstname + ', ' + person.lastname     return person end 

how can inject complete name in person object in controller/view can access person.complete_name?

thank time,
silviu

i think best way creation of complete_name attribute in person class:

def complete_name   firstname + ', ' + lastname end
