how to use ObjectId inside $in query in MongoDB? - php

Question

I have the following query in MongoDB
$this->createQueryBuilder()
->field('actor')->in($actorIdArray)
->getQuery()
->execute();
where the field actor is an object reference with annotation
#MongoDB\ReferenceOne(targetDocument="User", simple=true)
which means it will store the object Id instead of the full reference.
When $actorIdArray is an array of id with the form
["5706cb39821b166d3931f34f", "56015f7d4f8bd90b769e6e75"]
the query does not return nothing, which is the expected since the filed actor contains object id.
However, if I build the array this way
[new MongoId("5706cb39821b166d3931f34f"), new MongoId("56015f7d4f8bd90b769e6e75")]
it doesn't work either, which is quite surprising for me.
The log shows the query is made
{ "actor": {"$in":[{"$id":"5706cb39821b166d3931f34f"},{"$id":"56015f7d4f8bd90b769e6e75"}]}}
and I think it should be something like this
{ "actor": {"$in":[ObjectId("5706cb39821b166d3931f34f"),ObjectId("56015f7d4f8bd90b769e6e75"]}}
Not sure if I am doing something wrong,
any ideas?

As you can see in code source of Doctrine\ODM\MongoDB\Query\Builder -> references method:
public function references(object $document) : self
{
$this->requiresCurrentField();
$mapping = $this->getReferenceMapping();
$reference = $this->dm->createReference($document, $mapping);
$storeAs = $mapping['storeAs'] ?? null;
$keys = [];
switch ($storeAs) {
case ClassMetadata::REFERENCE_STORE_AS_ID:
$this->query[$mapping['name']] = $reference;
return $this;
.....
return $this;
}
You must know how the reference is built. Usually, this is by $id.
Use actor.$id as the field name:
$dm = $this->get('doctrine.odm.mongodb.document_manager'):
$documents = array();
foreach($actorIdArray as $id){
$documents[] = new MongoDB\BSON\ObjectId($id);
}
$this->createQueryBuilder()
->field('actor.$id')->in($documents)
->getQuery()
->execute();

Doctrine wants your array to be an array of documents.
You can load document references without query.
$dm = $this->get('doctrine.odm.mongodb.document_manager'):
$documents = array();
foreach($actorIdArray as $id){
$documents[] = $dm->getReference('AppBundle:Actor',$id); // <- this is the key
}
$this->createQueryBuilder()
->field('actor')->in($documents)
->getQuery()
->execute();
