Using a repository function in service Symofony - php

Question

I am using a service within twig like this
{{ count_service.getCount(term.getId) }}
I want the service to use a repository function, repository function
<?php
namespace AppBundle\Repository;
use Doctrine\ORM\EntityManagerInterface;
use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Mapping;
class SynonymRepository extends EntityRepository
{
public function getCount($termId)
{
$qbSynonymType = $this->getEntityManager()->createQueryBuilder();
$synonymTypes = $qbSynonymType->select('synonymType.id, synonymType.type')
->from('AppBundle:SynonymType', 'synonymType')
->getQuery()->getResult();
$qb = $this->getEntityManager()->createQueryBuilder();
$count = [];
$qb->select('count(synonym.synonymId)')
->from('AppBundle:Synonym','synonym');
foreach($synonymTypes as $type) {
$count[$type['type']] = $qb
->where('synonym.term = :termId')
->andWhere('synonym.synonymType = :type')
->setParameter('termId', $termId)
->setParameter('type', $type['id'])
->getQuery()->getSingleScalarResult();
}
$qbTerm = $this->getEntityManager()->createQueryBuilder()->from('AppBundle:Term', 'term');
$count['parent'] = "NaN";
$count['children'] = "NaN";
return $count;
}
}
My service.yml looks like this
synonymrepository:
class: Doctrine\ORM\EntityRepository
factory: ["#doctrine.orm.entity_manager", getRepository]
arguments:
- AppBundle\Entity\SynonymType
term_count:
class: AppBundle\Services\TermCount
arguments:
- "#synonymrepository"
And finally my service looks like this
<?php
namespace AppBundle\Services;
use AppBundle\Repository\SynonymRepository;
class TermCount
{
private $repository;
public function __construct()
{
$this->repository = new SynonymRepository();
}
public function getCount($termId)
{
return $this->repository->getCount($termId);
}
}
When running this I am getting the following error
Type error: Too few arguments to function Doctrine\ORM\EntityRepository::__construct(), 0 passed in /var/www/html/src/AppBundle/Services/TermCount.php on line 15 and exactly 2 expected
I assume this is happening because extending SynonymRepository with the EntityRepository requires EntityManagerInterface $em and Mapping\ClassMetadata $class. But I am not sure how pass them to EntityRepository.
I was using this answer to get me here, lost on how to actually implement the finall bit.
Thanks for helping.
UPDATE
Entity
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**

public function __construct()
{
// $this->synonymType = new ArrayCollection();
}
/**

public function getSynonymId(): int

}

public function getTerm(): Term
{
return $this->term;
}
/**

*/
public function setTerm(int $termId): Term
{
$this->term = $termId;
return $this->term;
}
/**
* #return SynonymType[]
*/
public function getSynonymType()
{
return $this->synonymType;
}
/**
* #param SynonymType $synonymType
* #return SynonymType
*/
public function setSynonymType(SynonymType $synonymType): SynonymType
{
$this->synonymType = $synonymType;
return $this->synonymType;
}
/**
* #return int
*/
public function getLanguageId(): int
{
return $this->languageId;
}
/**
* #param int $languageId
* #return Synonym
*/
public function setLanguageId(int $languageId): Synonym
{
$this->languageId = $languageId;
return $this;
}
/**
* #return string
*/
public function getSynonym(): string
{
return $this->synonym;
}
/**
* #param string $synonym
* #return Synonym
*/
public function setSynonym(string $synonym): Synonym
{
$this->synonym = $synonym;
return $this;
}
}

Answer 1

You need to use DI (Dependency injection) in your construct insted of using new cause as i see the erreur your SynonymRepository depends on other services
<?php
namespace AppBundle\Services;
use AppBundle\Repository\SynonymRepository;
class TermCount
{
private $repository;
public function __construct(SynonymRepository $synonymRepository)
{
$this->repository = $synonymRepository;
}
public function getCount($termId)
{
return $this->repository->getCount($termId);
}
}
