Problem with Yaml

Hello

I try to read yaml file. my model

class Enseignant < ActiveRecord::Base
  file_column :photo,
      :magick => {:geometry => "250x250>"},
      :root_path => File.join(RAILS_ROOT, "public/", "upload"),
      :web_root => "upload/"

  validates_file_format_of :photo, :in => ["gif", "png", "jpg"]
  validates_filesize_of :photo, :in => 15.kilobytes..1.megabyte
  #validates_image_size :photo, :min => "1200x1800"

  has_many :contributions
  has_many :enseignements, :through => :contributions
  has_one :user

  def adress
     #chargement du fichier de configuration
      adresse = YAML::load(IO.read("#{RAILS_ROOT}/db/adresses.yml"))
      return "totto"
  end
end

In my controler

  def show
    @enseignant = Enseignant.find(params[:id])
    @adresse = @enseignant.adress

It's correct ?

YAML::load(IO.read("#{RAILS_ROOT}/db/adresses.yml"))
