Query products with Doctrine ind Akeneo

I like to fetch some products from the Database with a custom command in akeneo. I'm using the ProductRepositoryInterface

public function read()
{
    return $this->repository->findBy(
        [
            'enabled' => true,
            'family' => ['projector', 'projector_child', 'projector_parent'],
        ]
    );
}

And this is the generated query:

SELECT t0.id AS id1, t0.is_enabled AS is_enabled2, t0.created AS created3, t0.updated AS updated4, t0.family_id AS family_id5 FROM pim_catalog_product t0 WHERE t0.is_enabled = ? AND t0.family_id IN (?)

As you can see in the Statement, the family is threaded as an Id. But I want to search by the family code.

What I have to change? In the Pim/Component/Catalog/Model/AbstractProduct is an attribute for the family and familyId. So there have to be a way to query for the family code.

Maybe it's relevant, but this is an Akeneo 1.6 installation.

So first, to query products in Akeneo, you should use the Product Query Builder (PQB). If you're using the 1.6, here is the link to the documentation to use it, it's pretty straightforward: https://docs.akeneo.com/1.6/cookbook/catalog/product/query.html

To have an exhaustive list of the filters on attributes & fields that can be used with the PQB, you can use the php app/console pim:product:query-help command on your PIM.

As you noticed, the family is not an attribute but a field, you'll find it in the field filters of the command above:

php app/console pim:product:query-help

Useable field filters...
+-----------------+--------------------------------+-----------------------------------------------------------+
| field           | operators                      | filter_class                                              |
+-----------------+--------------------------------+-----------------------------------------------------------+
| family          | IN, NOT IN, EMPTY, NOT EMPTY   | Pim\Bundle\CatalogBundle\Doctrine\ORM\Filter\FamilyFilter |
| family.id       | IN, NOT IN, EMPTY, NOT EMPTY   | Pim\Bundle\CatalogBundle\Doctrine\ORM\Filter\FamilyFilter |
| family.code     | IN, NOT IN, EMPTY, NOT EMPTY   | Pim\Bundle\CatalogBundle\Doctrine\ORM\Filter\FamilyFilter |
+-----------------+--------------------------------+-----------------------------------------------------------+

You can see now that you can search on the family.code field.

For your example, you'll end up with something like this:

<?php
// Get a new instance of the PQB
$pqbFactory = $this->getContainer()->get('pim_catalog.query.product_query_builder_factory');
$pqb = $pqbFactory->create([
    'default_locale' => 'en_US',
    'default_scope' => 'ecommerce'
]);

// Now you can search for products with your family codes
$pqb->addFilter(
    'family.code',
    'IN',
    ['projector', 'projector_child', 'projector_parent']
);

// Retrieve your products
$productsCursor = $pqb->execute();
foreach ($productsCursor as $product) {
    // your custom logic
}
