Auto_complete with has_one association

Hi, Have an issue with the rails auto complete, it works fine but I don't know how to find the id element search in the textfield.

Here is what I've done: <%= text_field_with_auto_complete :user, :ville_name, { :size => 15 }, { :url => formatted_villes_path(:js), :method => :get, :param_name => 'search' } %>

Model: class User < ActiveRecord::Base   attr_accessible :email, :ville_id, :newsletters, :role, :gender, :first_name, :last_name, :birth_date   serialize :newsletters

  has_one :ville

  GENDERS = %w(Homme Femme)   ROLES = %w(Admin Business User)

  def full_name   [@first_name, @last_name].join(' ')   end

  def ville_name     ville.name if ville   end

  def ville_name=(name)     self.ville = Ville.find_or_create_by_name(name) unless name.blank?   end

end

I want to find the "ville" ID typed in the auto complete field.
