PhalconPhp really DRY ?

Hi :)

I'm really new with phalconPHP, you made a really great job, but i get a tiny question, Phalcon is it really DRY ?

I'm writing an web application (Snippet share system for phalcon community) and i'm already tired ...

I made a controller with a simple method :

<?php

class SnippetController extends ControllerBase
{
    public function addAction()
    {
        if ($this->request->isPost())
        {
            // Get post values
            $language = $this->request->getPost('language');
            $description = $this->request->getPost('description');
            $code = $this->request->getPost('code');

            $snippet = new Snippets();
            $snippet->description = $description;
            $saved = $snippet->save();

            if ( ! $saved) 
            {
                $errors = '';

                foreach ($snippet->getMessages() as $message) {

                    $errors .= $message->getMessage() . '<br/>';

                }

                $this->flashSession->error($errors);
            }

        }

        // Set languages code into the view
        $this->view->setVar('languages', $this->config->languages->toArray());

    }
}

And a simple model :

<?php

use Phalcon\Mvc\Model\Validator\PresenceOf;

class Snippets extends \Phalcon\Mvc\Model
{

    /**
     *
     * @var integer
     */
    public $id;

    /**
     *
     * @var string
     */
    public $description;

    /**
     * Independent Column Mapping.
     */
    public function columnMap()
    {
        return array(
            'id' => 'id', 
            'description' => 'description'
            );
    }

    public function validation()
    {
        $this->validate(new PresenceOf(

            array(

                'field' => 'description',
                'message' => 'Le champ description est requis'

                )
            ));

        $this->validate(new PresenceOf(

            array(

                'field' => 'code',
                'message' => 'Le champ code est requis'

                )

            ));

        if ($this->validationHasFailed() === TRUE) {
            return FALSE;
        }
    }

}

Just to check 2 tiny required fields, i wrote more than 16 lines (A system to get error messages, and $this->validate() system)

In my previous framework, i made this for example :

// Add rules
$this->validation->rules('field_to_check', 'message', 'required|max_length[2]|equal[another_field]');

// Get errors
$this->validation->errors(); // Ready to print in the view

Don't forget i'm really new with Phalcon, maybe i made wrong/worst code, so what's the DRY way to check forms ?

Thx ;)
