Subject: how to check the existence of a connection

class Guest extends ActiveRecord\Model {

static $table_name = 'guest';
static $belongs_to = array(
        array('user')
    );
}
// model User.php
    public function getLogin(){
        return $this->users_login ? $this->users_login : 'no user';
    }

//and if you delete the user, but leave him messages
//trying to get the user name through communications
$post->user->getLogin();

//displays an error
Call to a member function getLogin() on a non-object

tell me how to solve this problem
