<?php
namespace app\forms;

use Phalcon\Forms\Form,
    Phalcon\Forms\Element\Select;

class RegionForm extends Form
{
    public function initialize()
    {
        $country = new Select('country', \countries::find(), array(
            'using' => array('id_num','name')
        ));

        $this->add($country);
    }
}

<? $this->forms->set('region', new app\forms\RegionForm()); ?>
<?= $this->forms->get('region')->render('country'); ?>

Result:

PHP Catchable fatal error:  Object of class countries could not be converted to string in ...

Using mongodb. What I'm doing wrong??

I've had the same problem. It seems that documents can't be used with select. You have to modify the data from mongodb before. See below what you can do :

use Models\Profiles;

class SignUpForm extends Form
{
    public function initialize()
    {
        //User profile
        $profiles = Profiles::find(array(array(
            'active' => true,
            'visible' => true),
            'fields' => array(
                '_id',
                'name')
        ));
        $profile = new Select('profile', Profiles::returnArrayForSelect($profiles), array(
            'useEmpty' => true,
            'emptyText' => 'You are ...',
            'emptyValue' => '',
            'class' => 'form-control index-form'
        ));
        $this->add($profile);
    }
}

use Phalcon\Mvc\Collection;

class Profiles extends Collection
{

    public $_id;
    public $active;
    public $name;
    public $visible;

    public static function returnArrayForSelect($obj)
    {
        $array = array();
        foreach ($obj as $v) {
            $array[(string) $v['_id']] = $v['name'];
        }
        return $array;
    }

}

It's now really clean but it works!
