Question 18 - AD0-E716 discussion

The developer should create an extension attribute on the Magento\Sales\Api\Data\OrderInterface interface and an after plugin on the Magento\Sales\Api\OrderRepositoryInterface::get() and Magento\Sales\Api\OrderRepositoryInterface::getList() methods.

The extension attribute will store the custom data. The after plugin will be used to add the custom data to the order object when it is fetched from the API.

Here is the code for the extension attribute and after plugin:

PHP

namespace MyVendor\MyModule\Api\Data;

interface OrderExtensionInterface extends \Magento\Sales\Api\Data\OrderInterface

{

/**

* Get custom data.

*

* @return string|null

*/

public function getCustomData();

/**

* Set custom data.

*

* @param string $customData

* @return $this

*/

public function setCustomData($customData);

}

namespace MyVendor\MyModule\Model;

class OrderRepository extends \Magento\Sales\Api\OrderRepositoryInterface

{

/**

* After get order.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface $order

* @return \Magento\Sales\Api\Data\OrderInterface

*/

public function afterGetOrder($subject, $order)

{

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

return $order;

}

/**

* After get list.

*

* @param \Magento\Sales\Api\OrderRepositoryInterface $subject

* @param \Magento\Sales\Api\Data\OrderInterface[] $orders

* @return \Magento\Sales\Api\Data\OrderInterface[]

*/

public function afterGetList($subject, $orders)

{

foreach ($orders as $order) {

if ($order instanceof OrderExtensionInterface) {

$order->setCustomData('This is custom data');

}

}

return $orders;

}

}

Once the extension attribute and after plugin are created, the custom data will be added to orders fetched from the API.
