Symfony One-To-Many, unidirectional with Join Table query - doctrine-orm

Question

I have some One-To-Many, unidirectional with Join Table relationships in a Symfony App which I need to query and I can't figure out how to do that in DQL or Query Builder.
The Like entity doesn't have a comments property itself because it can be owned by a lot of different types of entities.
Basically I would need to translate something like this:
SELECT likes
FROM AppBundle:Standard\Like likes
INNER JOIN comment_like ON comment_like.like_id = likes.id
INNER JOIN comments ON comment_like.comment_id = comments.id
WHERE likes.created_by = :user_id
AND likes.active = 1
AND comments.id = :comment_id
I've already tried this but the join output is incorrect, it selects any active Like regardless of its association with the given comment
$this->createQueryBuilder('l')
->select('l')
->innerJoin('AppBundle:Standard\Comment', 'c')
->where('l.owner = :user')
->andWhere('c = :comment')
->andWhere('l.active = 1')
->setParameter('user', $user)
->setParameter('comment', $comment)

Answer 1

I see 2 options to resolve this:
Make relation bi-directional
Use SQL (native query) + ResultSetMapping.
For the last option, here is example of repository method (just checked that it works):
public function getLikes(Comment $comment, $user)
{
$sql = '
SELECT l.id, l.active, l.owner
FROM `like` l
INNER JOIN comment_like ON l.id = comment_like.like_id
WHERE comment_like.comment_id = :comment_id
AND l.active = 1
AND l.owner = :user_id
';
$rsm = new \Doctrine\ORM\Query\ResultSetMappingBuilder($this->_em);
$rsm->addRootEntityFromClassMetadata(Like::class, 'l');
return $this->_em->createNativeQuery($sql, $rsm)
->setParameter('comment_id', $comment->getId())
->setParameter('user_id', $user)
->getResult();
}
PS: In case of Mysql, 'like' is reserved word. So, if one wants to have table with name 'like' - just surround name with backticks on definition:
* #ORM\Table(name="`like`")

Answer 2

I find the Symfony documentation very poor about unidirectional queries.
Anyway I got it working by using DQL and sub-select on the owning entity, which is certainly not as fast. Any suggestion on how to improve that is more than welcomed!
$em = $this->getEntityManager();
$query = $em->createQuery('
SELECT l
FROM AppBundle:Standard\Like l
WHERE l.id IN (
SELECT l2.id
FROM AppBundle:Standard\Comment c
JOIN c.likes l2
WHERE c = :comment
AND l2.owner = :user
AND l2.active = 1
)'
)
->setParameter('user', $user)
->setParameter('comment', $comment)
