doctrine2 - Symfony Doctrine Hydrator - With custom hydrator I lose my ManyToOne relation -


i extends objecthydrator benefit of hydration of manytoone relation , add field entity.

here hydrator: statisticsdatahydrator.php

namespace appbundle\hydrator\projectassignment;  use appbundle\entity\projectassignment; use doctrine\orm\internal\hydration\objecthydrator;      class statisticsdatahydrator extends objecthydrator     {         /**          * {@inheritdoc}          */         protected function hydraterowdata(array $data, array &$result)         {             $hydrated_result = array();             parent::hydraterowdata($data, $hydrated_result);              /** @var projectassignment $project_assignment */             $project_assignment = $hydrated_result[0][0];              $result[] = $project_assignment;         }     }

here config: config.yml

doctrine:     orm:         hydrators:             project_assignment_statisticsdata_hydrator: appbundle\hydrator\projectassignment\statisticsdatahydrator

where don't use hydrator have no problem:

/**  * @param projectstage $stage  * @return array  */ public function findbystagewithstatisticsdata(projectstage $stage){     $qb = $this->createquerybuilder('pa');      $qb         //->addselect('44')         ->where($qb->expr()->eq('pa.project_stage', ':stage'))         ->setparameter('stage', $stage);      return $qb->getquery()->getresult(); }

enter image description here

but when use hydrator:

/**  * @param projectstage $stage  * @return array  */ public function findbystagewithstatisticsdata(projectstage $stage){     $qb = $this->createquerybuilder('pa');      $qb         ->addselect('1234') // referencial value         ->where($qb->expr()->eq('pa.project_stage', ':stage'))         ->setparameter('stage', $stage);      return $qb->getquery()->getresult('project_assignment_statisticsdata_hydrator'); }

enter image description here

the strangest behavior same occure config: config.yml

doctrine:     orm:         hydrators:             project_assignment_statisticsdata_hydrator: doctrine\orm\internal\hydration\objecthydrator

i have tried kind of fetch on relation no success:

@orm\manytoone(... , fetch="eager") @orm\manytoone(... , fetch="lazy") ...

maybe have use proxy on entity, don't know :(

thank help!

great! found problem, query builder. had manually add joins , select of related objects.

/**  * @param projectstage $stage  * @return array  */ public function findbystagewithstatisticsdata(projectstage $stage){     $qb = $this->createquerybuilder('pa');      $qb         ->addselect('e') // added         ->addselect('r') // added         ->addselect('1234')         ->leftjoin('pa.employee', 'e')  // added         ->leftjoin('pa.role', 'r')  // added         ->where($qb->expr()->eq('pa.project_stage', ':stage'))         ->setparameter('stage', $stage);      return $qb->getquery()->getresult('project_assignment_statisticsdata_hydrator'); }

bonus, here hydrator (it can someone):

namespace appbundle\hydrator\projectassignment;  use appbundle\entity\hydrator\projectassignment\statisticsdata; use appbundle\entity\projectassignment; use doctrine\orm\internal\hydration\objecthydrator;  class statisticsdatahydrator extends objecthydrator {     /**      * {@inheritdoc}      */     protected function hydraterowdata(array $data, array &$result)     {         $hydrated_result = array();         parent::hydraterowdata($data, $hydrated_result);          /** @var projectassignment $project_assignment */         $project_assignment = $hydrated_result[0][0];          $keys = array_keys($hydrated_result); $key = end($keys);          $statistics_data = new statisticsdata($project_assignment);         $statistics_data->settotalworkedtime((int)$hydrated_result[$key][1]);          $project_assignment->setstatisticsdata($statistics_data);          $result[] = $project_assignment;     } }

in entity have folowing attribute/getter/setter

/********** non synced fields **********/  /** @var statisticsdata $statistics_data */ private $statistics_data;  /**  * @return statisticsdata  */ public function getstatisticsdata() {     return $this->statistics_data; }  /**  * @param statisticsdata $statistics_data  */ public function setstatisticsdata($statistics_data) {     $this->statistics_data = $statistics_data; }  /***************************************/
