为分组产品添加新产品类型

Question

我已经创建了一种新产品类型，如果我创建了一个分组产品，目前将不允许我在关联产品下选择任何新类型的产品。我启用了SQL记录，我看到了此查询：

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

我知道这是获取我可以为网格选择的产品的查询，但我无法弄清楚代码在哪里构建 WHERE 条款。这是查询的堆栈跟踪：

Answer 1

我终于找到了。当然是在config.xml中设置的。它在mage_adminhtml_block_catalog_product_edit_tab_super_group :: _ prepareCollection（）中。第二行获得了所有节点：

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

然后，在获取所有节点名称后，将其添加到查询中 ->addAttributeToFilter('type_id', $allowProductTypes); 称呼。
