A Model is an important part of MVC (Model-View-Controller) pattern as it represents the data of the application. In the same way, Models have a very useful role in Magento as well. Since editing Model from the core files is not a good practice, you should instead rewrite Model in Magento 2!
Hence, in this tutorial, I am going to teach you how to override models in Magento 2. What you need is a custom module to do that, so let’s begin.
Steps to Follow
- Create Directories
- Configuration of Module
- Registration of Module
- Override di.xml
- Override Product.php
- Launch SSH and Run Commands
Create Directories
In the root directory of your store, create the following directories in the same manner shown below:
Configuration of Module
Create module.xml in app/code/Magenticians/Moduleproduct/etc and add the following code in it:
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Magenticians_Moduleproduct" setup_version="1.0.1"> </module> </config>
Registration of Module
Create registration.php in app/code/Magenticians/Moduleproduct and add the following code in it:
<?php \Magento\Framework\Component\ComponentRegistrar::register( \Magento\Framework\Component\ComponentRegistrar::MODULE, 'Magenticians_Moduleproduct', __DIR__ );
Override di.xml
Create di.xml in app/code/Magenticians/Moduleproduct/etc in order to specify which model to override by using <preference for=””> and <preference type=””>.
Add the following code in it: The purpose of creating this file is to override di.xml file
<?xml version="1.0"?> <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="Magenticians\Moduleproduct\Model\Catalog\Product" /> </config>
<preference for=””> Which Model to override.
<preference type=””> Where to override.
Override Product.php
Now create Product.php in app/code/Magenticians/Moduleproduct/Model/Catalog and add the following code in i
<?php namespace Magenticians\Moduleproduct\Model\Catalog; class Product extends \Magento\Catalog\Model\Product { public function getName() { return $this->_getData(self::NAME) . ' + Demo Text'; } public function getSku() { return "123-Demo"; } }
In the code above, I have overriden the product name and product SKU.
Launch SSH and Run Commands
Run the following commands in the Magento 2 root directory:
php bin/magento module:enable Magenticians_Moduleproduct php bin/magento setup:upgrade php bin/magento setup:di:compile php bin/magento cache:clean php bin/magento cache:flush
Now it’s time to check results! Go to the product page and you should see this:
