Working with documents, _(*4)

$parentCategory = new Category();
$parentCategory->setName('Category 0');
$parentCategory->setDesc('Category 0 desc');
$parentCategory->save();

$category = new Category();
$category->setName('Category 1');
$category->setDesc('Category 1 desc');
$category->setCategory($parentCategory);
$category->save();

$product = new Product();
$product->setName('Product 1');
$product->setPrice(100);
$product->setIsActive(true);
$product->setCategory($category);
$product->setCreatedAt(time());

$product->save();

// by default Eager loading is enabled

$testProduct = Product::findFirst();
var_dump($testProduct->getCategory()->getName()); // Category 1
var_dump($testProduct->getCreatedAt()); // \MongoDate
var_dump($testProduct->getPrice()); // 100
var_dump($testProduct->getCategory()->getCategory()->getName()); // Category 0

// with disabled eager loading - efficient for big dataset

$testProduct = Product::findFirst();
var_dump($testProduct->getCategory()); // MongoId
var_dump($testProduct->getCreatedAt()); // int
var_dump($testProduct->isActive()); // true
var_dump($testProduct->getPrice()); // 100
var_dump($testProduct->getCategory()->getCategory()->getName()); // error!

Mapping cache

$config = new \Phalcon\Config([
    'mapping' => [
        'cache' => [
            'frontend' => [
                'driverClass' => 'Phalcon\Cache\Frontend\Output',
                'parameters' => [
                    'lifetime' => 3600
                ]
            ],
            'backend' => [
                'driverClass' => '\Phalcon\Cache\Backend\Mongo',
                'parameters' => [
                    'server' => 'localhost',
                    'db' => 'vegas_test',
                    'collection' => 'cache'
                ]
            ],
        ]
    ]
]);

$di->set('odmMappingCache', function() use ($di, $config) {
    $frontCacheClass = $config->mapping->cache->frontend->driverClass;
    $frontCache = new $frontCacheClass(
        $config->mapping->cache->frontend->parameters->toArray()
    );
    $backCacheClass = $config->mapping->cache->backend->driverClass;
    $cache = new $backCacheClass(
        $frontCache,
        $config->mapping->cache->backend->parameters->toArray()
    );

    return $cache;
}, true);

Mapping

Vegas ODM resolves referenced documents automatically. References must be defined in collection class by annotation. Consider the following code, _(*5)

class Test extends \Vegas\ODM\Collection {
    /**
     * @var \MongoId
     * @mapper \Vegas\ODM\Mapping\Mapper\MongoId
     */
    protected $_id;

    /**
     * @var int
     * @mapper
     */
    protected $int;

    /**
     * @var \MongoDate
     * @Mapper \Vegas\ODM\Mapping\Mapper\MongoDate
     */
    protected $date;
}

Annotation @var determines the variable type. Annotation @mapper (@Mapper) determines that property value will be mapped (casted) to value defined by @var. In @mapper annotation you can specify custom mapper class. (Note! Mapping class must implements interface \Vegas\ODM\Mapping\MapperInterface), _(*6)
