Symfony Return child objects depend of some property - symfony

Question

Im using Symfony 4 + Api Platform. I have an entity (Insurance) that it is relationed with another entity (MediaObject). When I try to GET some item of Insurance, it is returning all the MediaObjects items that they are relationed with it. However, I dont want to return all the MediaObjects. I need MediaObjects where deletedAt is null.
How can I fix that?
I have a DoctrineExtension where I coded:
$queryBuilder->join(sprintf('%s.mediaObjects', $rootAlias), 'mo');
$queryBuilder->andWhere(sprintf('%s.deletedAt IS NULL', $rootAlias));
$queryBuilder->andWhere('mo.deletedAt IS NULL');
but nothing happens. It is still returning all items.

You should use conditional join and apply filter to the joining collection not to the whole set:
$queryBuilder->join(sprintf('%s.mediaObjects', $rootAlias), 'mo', 'WITH', 'mo.deletedAt IS NULL');
$queryBuilder->andWhere(sprintf('%s.deletedAt IS NULL', $rootAlias));
Keep in mind this query will not return insurance entities that do not have non-deleted media objects because of join. If you want it to also return objects with empty media collection change join to leftJoin
