symfony - Why Doctrine MongoDB ODM findBy and execute returns different classes? -


sbased on doctrine documentation $qb->getquery()->execute(); return cursor iterator on results $qb->find($criteria); returns actual found documents.

i using symfony2 mongodbbundle , avoid iterating on result set in repository classes. 

// returns product document  $entity = $this->get('doctrine_mongodb')                ->getrepository("mybundle:product")                ->findoneby(array('title' => 'somthing'));   // returns cursor $entity = $this->get('doctrine_mongodb')                ->getrepository("mybundle:product")                ->customfunctionwithcreatequerybuilder(array('title' => 'somthing'));

how can make cutomfunctionwithcreatequerybuilder() returns same class/result findoneby?

also how can make execute() returns embedded documents?

edit

content of cutomfunctionwithcreatequerybuilder:

class productrepository extends documentrepository {  public function customfunctionwithcreatequerybuilder($param, $hydrate = true) {          $query = $this->createquerybuilder()                 ->select()                 ->hydrate($hydrate);          if (isset($param['unique_id'])) {             $query->field('id')->equals($param['unique_id']);         }          return $query->getquery()->execute();     }  }

you can use getsingleresult() if want 1 result , set eagercursor true data @ once. in example:

    [...]       if (isset($param['unique_id'])) {         $query->field('id')->equals($param['unique_id']);     }      return $query->eagercursor(true)->getquery()->getsingleresult();       [...]
