Magento 2 - How to add short_description to cart item?

Question

On the /checkout/cart page I like to add the short description attribute to the cart items. But if I look in $item->getProduct()->getShortDescription() I get an empty string, also $item->getProduct()->hasShortDescription() returns false.

I also read somewhere that the short_description attribute isn't loaded automatically and need to add this piece of xml to M2

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/catalog_attributes.xsd">
    <group name="quote_item">
        <attribute name="short_description"/>
    </group>
</config>

But I am unsure of where to add this exactly or that I even need this. So can somebody help me out?

Answer 1

We can add the custom attribute to catalog_attributes.xml under etc folder.

For example:

app/code/Company/Catalog/etc/catalog_attributes.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/catalog_attributes.xsd">
    <group name="quote_item">
        <attribute name="short_description"/>
    </group>
</config>

Now, we can get $item->getProduct()->getShortDescription().

See more here: vendor/magento/module-sales/etc/catalog_attributes.xml

Full solution as provided by @Khoa TruongDinh

Create a custom module in app/code/vendor/ModuleName/.

app/code/vendor/ModuleName/etc/catalog_attributes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Catalog:etc/catalog_attributes.xsd">
    <group name="quote_item">
        <attribute name="short_description"/>
    </group>
</config>

app/code/vendor/ModuleName/etc/module.xml

<?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="vendor_ModuleName" setup_version="0.0.1">
        <sequence>
            <module name="Magento_Sales"/>
            <module name="Magento_Catalog"/>
        </sequence>
    </module>
</config>

app/code/vendor/ModuleName/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'vendor_ModuleName',
    __DIR__
);

Now we can add in any phtml where it is needed. echo $product->getShortDescription()

Run magento commands:

php bin/magento module:enable vendor_ModuleName

php bin/magento setup:upgrade

php bin/magento cache:clean
