Ajouter un nouveau type de produit pour le produit groupé

Question

J'ai créé un nouveau type de produit et si je crée un produit groupé ce moment ne me laisse pas sélectionner tous les produits de mon nouveau type sous produits associés. J'activé la journalisation SQL et je vois cette requête:

SELECT 
    `e` . *,
    `links`.`link_id`,
    `link_attribute_position_int`.`value` AS `position`,
    `link_attribute_qty_decimal`.`value` AS `qty`
FROM
    `catalog_product_entity` AS `e`
        LEFT JOIN
    `catalog_product_link` AS `links` ON links.linked_product_id = e.entity_id
        AND links.link_type_id = 3
        AND links.product_id = '4'
        LEFT JOIN
    `catalog_product_link_attribute_int` AS `link_attribute_position_int` ON link_attribute_position_int.link_id = links.link_id
        AND link_attribute_position_int.product_link_attribute_id = '2'
        LEFT JOIN
    `catalog_product_link_attribute_decimal` AS `link_attribute_qty_decimal` ON link_attribute_qty_decimal.link_id = links.link_id
        AND link_attribute_qty_decimal.product_link_attribute_id = '3'
WHERE
    (((`e`.`required_options` != '1') OR (`e`.`required_options` IS NULL)))
    AND (((`e`.`type_id` = 'simple') OR (`e`.`type_id` = 'virtual') OR (`e`.`type_id` = 'downloadable')))
    AND (`e`.`entity_id` != '4')
ORDER BY `e`.`entity_id` DESC
LIMIT 20

Je sais que c'est la requête d'obtenir les produits que je peux sélectionner pour la grille, mais je ne peux pas savoir où le code est que builds la clause WHERE. Voici la trace de la pile pour la requête:

Answer 1

Je trouve enfin. Il est situé dans le config.xml, bien sûr. Son dans Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Super_Group :: _ prepareCollection (). La deuxième ligne obtient tous les noeuds:

Mage::getConfig()->getNode('global/catalog/product/type/grouped/allow_product_types')->children();

Alors, après avoir obtenu tous les noms de noeud, son ajouté à la requête avec un simple appel ->addAttributeToFilter('type_id', $allowProductTypes);.
