php - zf2 doctrine odm collection hydration -

hi im using doctrine odm , have trouble hydrator. can't make extract on document embed collection nor reference class. extract result these class give me object , need have them in array rest module consumed backbone implementation. here example class : analyse.php document

<?php namespace application\document;  use doctrine\odm\mongodb\mapping\annotations odm; use doctrine\common\collections\collection;  /**  * application\document\analyse  *  * @odm\document(collection="analyse")  */ class analyse extends basedocument {     /**      * @odm\id      */     protected $id;      /**      * @odm\field(type="string")      */     protected $nom;      /**      * @odm\field(type="string")      * @odm\index      */     protected $alias;      /**      * @odm\embedmany(targetdocument="elementsanalyse")      */     protected $elements = array();      public function __construct()     {         parent::__construct();         $this->elements = new \doctrine\common\collections\arraycollection();     }      public function getid()     {         return $this->id;     }      public function setnom($nom)     {         $this->nom = $nom;         return $this;     }      public function getnom()     {         return $this->nom;     }      public function setalias($alias)     {         $this->alias = $alias;         return $this;     }      public function getalias()     {         return $this->alias;     }      public function addelements(collection $elements)     {         foreach ($elements $element) {             $this->elements->add($element);         }      }      public function removeelements(collection $elements)     {         foreach ($elements $item) {             $this->elements->removeelement($item);         }     }      public function getelements()     {         return $this->elements;     }  } 

elementanalyse.php collection

<?php  namespace application\document;  use doctrine\odm\mongodb\mapping\annotations odm; use doctrine\common\collections\collection;  /**  * application\document\valeurnormales  *  * @odm\embeddeddocument  *  */ class elementsanalyse {      /**      * @odm\field(type="string")      */     protected $nom;      /**      * @odm\field(type="string")      */     protected $unite;      /**      * @odm\embedmany(targetdocument="valeurnormales")      */     protected $valeurnormales = array();      /**      * @odm\field(type="string")      */     protected $type;       public function __construct()     {         $this->valeurnormales = new \doctrine\common\collections\arraycollection();     }      /**      * set nom      */     public function setnom($nom)     {         $this->nom = $nom;         return $this;     }      /**      * nom      */     public function getnom()     {         return $this->nom;     }      /**      * set unite      */     public function setunite($unite)     {         $this->unite = $unite;         return $this;     }      /**      * unite      *      * @return string      */     public function getunite()     {         return $this->unite;     }      /**      * add valeurnormales      */     public function addvaleurnormales(collection $vn)     {         foreach ($vn $item) {             $this->valeurnormales->add($item);         }     }      public function removevaleurnormales(collection $vn)     {         foreach ($vn $item) {             $this->valeurnormales->removeelement($item);         }     }      /**      * valeurnormales      */     public function getvaleurnormales()     {         return $this->valeurnormales;     }      /**      * set type      *      * @param $type      * @return analyse      */     public function settype($type)     {         $this->type = $type;         return $this;     }      /**      * type      *      * @return type      */     public function gettype()     {         return $this->type;     }      /**      * toarray function      */     public function toarray()     {         return get_object_vars($this);     }      /**      * fromarray function      *      */     public function fromarray(array $array)     {         $objects = $this->toarray();         foreach($array $item => $value)         {             if(array_key_exists($item, $objects))             {                 $this->$item = $value;             }         }     }  } 

here getlist method

public function getlist()     {         $hydrator = new doctrinehydrator($entitymanager, 'application\document\analyse');          $service = $this->getanalyseservice();         $results = $service->findall();          $data = $hydrator->extract($results);         return new jsonmodel($data);     } 

and var_dump($data['elements']) return object collection or proxy class can me. appreciated been 2 weeks can't make work. read hydrator strategy out there don't knnow how implement it.

currently, doctrine odm implementation not provide recursion embedded objects , references.

if use var_dump() on $hydrator->extract($results), you'll see embeds/references there in original object format.

what can here use zend\stdlib\hydrator\strategy, , define own logic extraction/hydration. doctrine extends zend framework 2's hydrators , strategies.
