I'm updating product stock inventory attribute programactically. Considering performance, instead of saving whole product, I'm saving quantity attribute only.
// $quantity value $stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product); $mainCurrQty = $stock->getQty(); $stock->setQty($mainCurrQty-$quantity);
At the same time I want to call
catalog_product_save_after observer which is not working as it's not saving the product and saving the attribute value only. How I can call
catalog_product_save_after observer when only a particular attribute value is updated programatically?
