Overriding or Rewrite Magento 2 Model
Magento 2 Models play an even bigger role, as they typically contain the “Business Logic” that’s often relegated to the Controller or Helper methods in other PHP MVC frameworks. Now we start to overriding or rewriting core Product model. The model we are overriding is Product Model.
Create a di.xml file in a following directory QaisarSatti/HelloWorld/etc/
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<preference for="Magento\Catalog\Model\Product" type="QaisarSatti\HelloWorld\Model\Rewrite\Catalog\Product" />
The step2 to overriding or rewriting Magento2 model is to create a Product.php helper file in the following directory QaisarSatti/HelloWorld/Model/Rewrite/Catalog
* Catalog Product Rewrite Model
* @category QaisarSatti
* @package QaisarSatti_HelloWorld
* @author Muhammad Qaisar Satti
class Product extends \Magento\Catalog\Model\Product
public function __construct()
echo "Overrding/ Rewrite Working"; die();
As following code you can rewrite or override any Magento 2 model using the same method.
