In Magento 2, to add a new action to a pre-existing route without interfering with the existing functionality, the new action should be placed in the same directory structure under the new module’s controller namespace. Magento's autoloading mechanism will automatically detect and include it alongside the original module's actions.

Here's how you can achieve this:

Directory Structure: Ensure that your new module's controller directory structure mirrors that of the original module.

Controller Action: Define the new action within the appropriate directory.

For example, if you want to add a new action to the catalog route in Magento_Catalog:

Create a directory structure app/code/My/Module/Controller/Catalog/.

Add your new action class in this directory, for example:

namespace My\Module\Controller\Catalog;

use Magento\Framework\App\Action\Action;

use Magento\Framework\App\Action\Context;

class NewAction extends Action

{

public function __construct(Context $context)

{

parent::__construct($context);

}

public function execute()

{

// Your custom logic here

}

}

Router Configuration: Magento automatically includes this action when the route matches.

By following this method, you ensure that your new action is added seamlessly without modifying the original module or causing conflicts. Magento's router will include and recognize your action based on the directory and namespace conventions.

To allow the is_delayed EAV attribute to be used in the .phtml cart page, the developer needs to create a new file called etc/catalog_attributes.xmi. This file will contain the definition of the is_delayed attribute.

The following code shows how to create the etc/catalog_attributes.xmi file:

XML

Is Delayed

This attribute indicates whether the product is delayed.

10

false

Once the etc/catalog_attributes.xmi file has been created, the is_delayed attribute will be available in the .phtml cart page. The attribute can be accessed using the getIsDelayed() method of the Product class.

PHP

$product = $block->getProduct();

$isDelayed = $product->getIsDelayed();

The isDelayed variable will contain the value of the is_delayed attribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.

In Adobe Commerce, to retrieve custom extension attributes on an entity such as a quote, you need to ensure that these attributes are properly loaded when accessing the entity directly via repository interfaces. When fetching a single quote, it is essential to use a plugin on CartRepositoryInterface::get to include the extension attributes as this method is responsible for loading individual quote data.

If the plugin is missing for the get method, the extension attributes won’t be loaded for single quote retrieval, leading to their absence in the result.
