Shopware 6: association with nested association, is this posible? – PHP

I’ve a association in my EntityDefinition:

...
class ParentEntityDefinition extends EntityDefinition
{
    ...
    protected function defineFields(): FieldCollection
    {
        return new FieldCollection([
            
            (new OneToOneAssociationField(
                'childEntity',
                'id',
                'parent_entity_id',
                ChildEntityDefinition::class,
                false)),
        ]);
    }

    ...
}

The ChildEntity has a fk_field to currency_entity. To avoid an additional request to get the currency, my question:

  • Is, and if, how is it posible to get the currency entity with nested association?

    Yes that is totally possible.

    You can add nested associations in the following way:

    $criteria->addAssociation('childEntity.parentEntity');

    Note the dot syntax to specify nested associations, the same syntax can be used over the HTTP-API as well.

    Take a look at the official docs as well: https://developer.shopware.com/docs/guides/plugins/plugins/framework/data-handling/reading-data#associations

    Yes, just use the dot notation to chain associations when you create the Criteria programmatically. Given you use the repository of the parent entity:

    $criteria = new Criteria();
$criteria->addAssociation('childEntity.currencyEntity');

    In the request body for an API search request:

    {
    "associations": {
        "childEntity": {
            "associations": {
                "currencyEntity": {}
            }
        }
    }
}
