Query Build doctrine Symfony - symfony

Question

I have 2 entity (Rule and analysisRule)( association one to many)
I try to make a query that counts the number of idAnalyseRule that have an idAnalyse pass as a parameter in the function
example:
I pass idRule = 15 as a parameter, the query will count all IdAnalysisRules that have an idAnalysis = 15
I do not know how it works but I try it like that
$qb = $this->createQueryBuilder('p');
$expr = $qb->expr();
$qb->andWhere(
$expr->eq('p.analyse', ':analyse')
)
->setParameter('analyse', $analyse);
return $qb->getQuery()->getSingleResult();
this is the manager
/**
* #param $analyse
* #return mixed
*/
public function errorsAnalyseRule(Analyse $analyse){
return $this->repository->totalErrors($analyse);
}
this is controller
/**
*
* Get a totalError by idAnalyse.
* #param Analyse $analyse
* #param AnalyseRuleManager $analyseRuleManager
* #return ApiResponse
*
* #SWG\Parameter(name="id", in="path", type="integer", description="Supplier Id"))
* #SWG\Response(response=200, description="Returns the nbErrors")
*
* #Rest\Get("analyses/{id}", requirements={"id"="\d+"})
*/
public function getTotalErrorsAction(Analyse $analyse, AnalyseRuleManager $analyseRuleManager)
{
return new ApiResponse(['nbErrors' => $analyseRuleManager->errorsAnalyseRule($analyse)]);
}
I am in a state of blockage for 3 days

Answer 1

This works with an inner join. In the repository of analysisRule you have to add the function that makes the query and returns the count:
public function countAnalysisRule(Rule $rule)
{
return $this-createQueryBuilder('a')
->select('count(a)')
->innerJoin('a.Rule', 'rule')
->where('rule.id = :rule')
->setParameter('rule', $rule->getId())
->getQuery()
->getSingleScalarResult();
}
Don't forget ofcourse to add a use of the Rule class.

According to https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/query-builder.html
You should use:
$qb = $entityManager->createQueryBuilder();
$qb->select($qb->expr()->count('p.id'))
->from('App:AnalyseRule','p')
->where('p.analyse', ':analyse')
->setParameter('analyse', $analyse);
$count = $qb->getQuery()->getSingleScalarResult();
where $analyse = 15 in your case !
If you are under 2.6 for doctrine prefer:
$qb = $entityManager->createQueryBuilder();
$qb->select('count(p.id)')
->from('App:AnalyseRule','p')
->where('p.analyse', ':analyse')
->setParameter('analyse', $analyse);
$count = $qb->getQuery()->getSingleScalarResult();
