Requirement

PHP 5.4

cd libraries
git clone git@github.com:jails/li3_behaviors.git

Include the library in your /app/config/bootstrap/libraries.php

Libraries::add('li3_behaviors');

Presentation

Model behaviors providing a simple way to extend models. This pattern allow common logic to be encapsulated inside behaviors for keeping models lite and composed only by its own business logic.

API

Simple model creation attached to a behavior:

<?php
//app/models/Posts.php
namespace app\models;
use li3_behaviors\data\model\Behaviors;

class Posts extends \lithium\data\Model {
    use Behaviors;

    protected $_actsAs = ['Slug' => [
        'fields' => ['title' => 'title', 'name' => 'slug']
    ]];
}
?>

<?php
//app/extensions/data/behavior/Slug.php
namespace app\extensions\data\behavior;

use lithium\util\Inflector;

class Slug extends \li3_behaviors\data\model\Behavior {

	public function __construct(array $config = []) {
		$defaults = [
			'fields' => ['label' => 'slug']
		];
		parent::__construct($config + $defaults);
	}

	protected function _init() {
		parent::_init();
		if ($model = $this->_model) {
			$behavior = $this;
			$model::applyFilter('save', function($self, $params, $chain) use ($behavior) {
				$params = $behavior->invokeMethod('_slug', array($params));
				return $chain->next($self, $params, $chain);
			});
		}
	}

	protected function _slug($params) {
		extract($this->_config);
		foreach ($fields as $from => $to) {
			if (isset($params['data'][$from])) {
				$params['data'][$to] = Inflector::slug($params['data'][$from]);
			}
		}
		return $params;
	}
}
?>
