php - Doctrine - FindBy on One To Many relation -

lets suppose have 'product' entity

/** * @orm\entity * @orm\table(name="es_product") */ class product extends \kdyby\doctrine\entities\baseentity {  /**  * @orm\id  * @orm\column(type="integer")  * @orm\generatedvalue  */ private $id;  ...   /**  * @orm\onetomany(targetentity="productlang", mappedby="product", cascade={"all"}, indexby="iso")  */ protected $contentlang;  ... 

and productlang entity

/** * @orm\entity * @orm\table(name="es_product_lang") */ class productlang  extends \kdyby\doctrine\entities\baseentity {  /**  * @orm\id  * @orm\manytoone(targetentity="\app\modules\cmsadmin\model\lang")  */ protected $lang;  /**  * @orm\id  * @orm\manytoone(targetentity="product", inversedby="contentlang")  */ protected $product;  /**  * @orm\column(type="string")  */ protected $name; 

as can see there 1 many connection between product , productlang

the question is, there possibility use doctrine's 'findby()' method 'product' repository find products based on productlang.name?

i know can

productlangrepo->findby( [ 'product' => $product, 'name' => $name])  

but need stay in productrepo, means, like

productrepo->findby( [ 'contentlang["iso"]->name' => $name ])  

i think approaching wrong way. should use findby on language repo:

$language = productlangrepo->findby(array('name' => $name)); 

and connected products (since have 2 way connection):

$productsforlanguage = $language->getproduct() //btw since many 1 should named products not product. 

then have product collection can filter. if still want go product repo side have use dql or criteria write more complex filters.
