down vote favorite I have installed Amasty order attributes extension
I followed http://magehit.com/blog/how-to-get-value-of-custom-attribute-on-magento-2-rest-api/
and created
app/code/Amasty/Orderattr/etc/extension_attributes.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
<extension_attributes for="Magento\Sales\Api\Data\OrderInterface">
<attribute code="order_source" type="string" />
</extension_attributes>
</config>
2.Created events.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
<event name="sales_order_load_after">
<observer name="sales_order_load_order_source" instance="Amasty\Orderattr\Observer\Sales\OrderLoadAfter" />
</event>
</config>
3.created Observer app/code/Amasty/Orderattr/Observer/Sales/OrderLoadAfter.php
<?php
namespace Amasty\Orderattr\Observer\Sales;
use Magento\Framework\Event\ObserverInterface;
use Magento\Sales\Api\Data\OrderExtensionInterface ;
class OrderLoadAfter implements ObserverInterface
{
public function execute(\Magento\Framework\Event\Observer $observer)
{
$order = $observer->getOrder();
$extensionAttributes = $order->getExtensionAttributes();
if ($extensionAttributes === null) {
$extensionAttributes = $this->getOrderExtensionDependency();
}
$attr = $order->getData('order_source');
$extensionAttributes->setOrderSource($attr);
$order->setExtensionAttributes($extensionAttributes);
}
private function getOrderExtensionDependency()
{
$orderExtension = \Magento\Framework\App\ObjectManager::getInstance()->get(
'\Magento\Sales\Api\Data\OrderExtension'
);
return $orderExtension;
}
}
After deleting the generation folder ,the OrderExtension.php was auto generated with get and set methods
var\generation\Magento\Sales\Api\Data\OrderExtension.php
But in Api response I did not see any of my custom order attributes for order created by amasty extension.
Where I am going wrong or another way to do this.
