Lithium autoload model relationships to entity

gistfile1.php

<?php
namespace app\extensions\data\entity;

class Document extends \lithium\data\entity\Document {

	public function &__get($name) {
		if ($result = parent::__get($name)) {
			return $result;
		}
		if (($model = $this->_model) && ($rel = $model::relations($name))) {
			$this->_relationships[$name] = $rel->get($this);
			return $this->_relationships[$name];
		}
		return $result;
	}

}

//connections.php

Connections::add('default', [
	'type' => 'MongoDb',
	'host' => 'localhost',
	'database' => 'database',
	'classes' => [
		'entity' => 'app\extensions\data\entity\Document'
	]
]);

Yeah, for simple lazy-loading that's pretty clean. I dunno if I'd recommend it for anything serious, since this style makes it very easy to run lots of queries in a loop.
