FuelPHP - 在ORM模型中使用核心类

Question

How can I use a core classe in my ORM Model ?

Is working:

protected static $_properties  = array(
    'id',
    'user_id',
    'v_key' => array('default' => 'abc' ),
    'a_key' => array('default' => 'def' ),
    'created_at',
    'updated_at'
);

Isn't working:

protected static $_properties  = array(
    'id',
    'v_key' => array('default' => Str::random('alnum', 6) ),
    'a_key' => array('default' => Str::random('alnum', 6) ),
    'created_at',
    'updated_at'
);

Thanks!!

Ok, I used an observer to do that.

/classes/observer/session.php

<?php

namespace Orm;

use Str;

class Observer_Session extends Observer {
  public function after_create(Model $session) {

    $session->v_key = Str::random('alnum', 6);
    $session->a_key = Str::random('alnum', 6);

  }

/classes/model/session.php
