我想为特定商店视图的所有产品选中“用作默认值”
我用这个代码
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$collection = $this->_productCollectionFactory->create();
foreach($collection as $data){
$product=$this->_product->setStoreId(1)->load($data->getEntityId());
$product->setData('name',false);
$product->save();
}
但这是从类别中删除产品。 您能否告诉我如何以编程方式检查“用作默认复选框”。
【问题讨论】：
以下解决方案创建一个 CLI 命令来直接操作数据库并删除商店特定的产品属性信息。它是为 Magento 企业版编写的，因此如果您使用的是社区版，则必须修改此代码以使用 entity_id 而不是 row_id。
请注意这一点。此处提出的解决方案绕过模型类并对默认数据库连接的catalog_product_entity_datetime、catalog_product_entity_decimal、catalog_product_entity_int、catalog_product_entity_text 和catalog_product_entity_varchar 表执行直接删除查询。首先备份您的数据库。

php -f bin/magento module:enable StackOverflow_Question40177336
该命令有两个必需的参数，attribute_code 和 store。 Store 可以是 ID 或 Code。由于显而易见的原因，不允许使用管理存储。如果您希望仅针对特定 SKU（省略此参数适用于所有产品），该命令还有一个可选的 SKU 第三个参数。
例如，如果您想从“默认”存储视图中删除所有“名称”值，您的命令如下：
php -f bin/magento catalog:product:attributes:use-default-value name default
