php - Symfony2 one form for many entities Many To One relation -

i need form issue. have main entity - user:

class user { private $id; private $name; private $surname; private $description; private $photo;  /**  * @orm\onetomany(targetentity="adress", mappedby="user", cascade={"persist", "remove"})  */ private $adresses;  /**  * @orm\manytomany(targetentity="groups", inversedby="users")  * @orm\jointable(name="users_groups")  */ private $groups; 

i have get, set, __construct etc...

then address entity:

class adress { private $id; private $city; private $street; private $number;  /**  * @orm\manytoone(targetentity="user", inversedby="adresses", cascade={"persist", "remove"})  * @orm\joincolumn(name="user_id", referencedcolumnname="id")  */ private $user; 

and form adress:

class adresstype extends abstracttype { public function buildform(formbuilderinterface $builder, array $options) {     $builder             ->add('city')             ->add('street')             ->add('number')             ->add('user')     ; } 

etc.. (generate crud)

and form user:

    public function buildform(formbuilderinterface $builder, array $options) {     $builder             ->add('name')             ->add('surname')             ->add('description')             ->add('photo', 'file', array('label' => 'photo (files: .jpg, .png)', 'data_class' => null))             ->add('groups')             ->add('adresses', 'collection', array(                 'type' => new adresstype(),                 'allow_add' => true,                 'allow_delete' => true,                 'cascade_validation' => true,                 'by_reference' => false,             )) 

controller new user:

    private function createcreateform(user $entity) {      $adress = new adress();     $entity->addadress($adress);      $form = $this->createform(new usertype(), $entity, array(         'action' => $this->generateurl('user_create'),         'method' => 'post',     ));      $form->add('submit', 'submit', array('label' => 'create'));      return $form; }    public function createaction(request $request) {     $entity = new user();      $form = $this->createcreateform($entity);     $form->handlerequest($request);      if ($form->isvalid()) {         //add photo         /**          * @var symfony\component\httpfoundation\file\uploadedfile $file           */         $photo = $entity->getphoto();          //generate name photo         $photoname = md5(uniqid()) . '.' . $photo->guessextension();          $photo->move($this->getparameter('photo_directory'), $photoname);          $entity->setphoto($photoname);          $em = $this->getdoctrine()->getmanager();         $em->persist($entity);         $em->flush();          return $this->redirect($this->generateurl('user_show', array('id' => $entity->getid())));     }      return array(         'entity' => $entity,         'form' => $form->createview(),     ); } 

the results this: click here don't know how solve th problem add information 2 entities (user, adress) in 1 form. don't know should 'user' in adresstype - because shows select field want add new relation between adress , user.

can me - spend few hours , can't figure out. :) thank you!
