I'd like to achieve a similar setup as below, but in CakePHP and where the virtual attributes are created using code, not SQL (as documented at http://book.cakephp.org/view/1070/Additional-Methods-and-Properties#Using-virtualFields-1590).

class User < ActiveRecord::Base  
  # Getter  
  def full_name  
    [first_name, last_name].join(' ')  
  end  

  # Setter  
  def full_name=(name)  
    split = name.split(' ', 2)  
    self.first_name = split.first  
    self.last_name = split.last  
  end  
end
