Is it possible to use references for many to many relationships?

[Shelamkoff]

Hi, an exception is thrown when trying to save a relationship using a reference object.
when attempting to store a relationship using a reference object, the following error occurs: "Typed property Cycle\ORM\Transaction\Tuple::$node must not be accessed before initialization."

foreach (json_decode($data['tags'], true) as $tag) {
    $post->tags->add(isset($tag['id']) ?
        new Reference('tag', ['id' => $tag['id']])
        : new Tag($tag['name'])
   );
}
$entityManager->persist($post, true)->run();

I'm not sure that should work in the current implementation.
It looks like good feature request: supporting for case when subitem of HasMany/ManyToMany relation can be Reference

Hello @roxblnfk does that mean that the only way to create a new record that has a ManyToMany to existing records is to load those existing records and assign them to the ManyToMany property? This would have a pretty severe scalability issue in some cases.

Can you think of a workaround, like exposing a OneToMany relationship to the join table and using references to it when saving/updating a record?

Our API allows a user to give an array of primary keys for many to many relationships, we then would ideally create reference objects for each of these IDs instead of loading them into memory just to create the relationship.

Thanks

I'll check this possibility
