Symfony2, createQueryBuilder count one to many relationship - symfony

Question

I have 2 entities linked by a one to many relation.
Recruitment and Candidat
You may have many candidats for one recruitment.
I want to list all recruitment and count how many candidat each recruitment has.
I use the recruitment repository and put the code:
public function myFindAllRecruitment()
{
$qb = $this->createQueryBuilder('r');
$qb->select('r');
$qb->Join('r.candidat', 'c');
$qb->addSelect("COUNT(c.id) as candidatCount");
$qb->groupBy('r.id');
$qb->orderBy('r.id', 'DESC');
return $qb
->getQuery()
->getResult()
;
}
In my RecruitmentController I have:
$listRecruitment = $repository->myFindAllRecruitment();
In my TWIG view something like:
{% for recruitment in listRecruitment %}
<tr>
{#(this is line 48)#}<td>{{ recruitment.id }}</td>
<td>{{ recruitment.titleFr }}</td>
<td>{{ recruitment.locationFr }}</td>......
And I get this error:
"Key "id" for array with keys "0, candidatCount" does not exist in MyBundle:Recruitment:index.html.twig at line 48"
If someone knows what wrong with my query it will be nice.
Thank you

Answer 1

So you have this Candidat entity like this
......
/**
* #ORM\ManyToOne(targetEntity="Recruitment", inversedBy="candidates")
*/
$recruitment;
....
Then your query should look like this:
public function myFindAllRecruitment()
{
$qb = $this->createQueryBuilder('r');
$qb->select('r');
->addSelect('(SELECT count(c) FROM PATHTO\Bundle\Entity\Candidat as c WHERE c.rectuitment = r.id group by c.rectuitment) as count)');
->orderBy('r.id', 'DESC');
return $qb->getQuery()->getResult();
}
you will get output like this:
[
0 => [
'rectuitment' => ...Object,
'count'=> ...,
...
]

Answer 2

Ok, thank you, I found the solution.
It was in the TWIG render:
Objects were accessible with [0] and [1] or ['candidatCount'] for the the count
Code exemple:
{% for recruitment in listRecruitment %}
<tr>
<td>{{ recruitment[0].id }}</td>
<td>{{ recruitment[0].titleFr }}</td>
<td>{{ recruitment[0].locationFr }}</td>
<td>{{ recruitment[0].typePoste }}</td>
<td>{{ recruitment[0].dateins|date('Y-m-d') | localizeddate('full', 'none') }}</td>
<td>
{{ recruitment['candidatCount'] }}........
And the query was good.
Thank you
