I want to add custom attribute to quote item called item_delete for example. This attribute it's to know if a a item can or can not be deleted from cart.
I've already created an extension_attributes.xml file with the following.
<?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\Quote\Api\Data\CartItemInterface">
<attribute code="is_delete" type="boolean" />
</extension_attributes>
Also i've a plugin:
/**
* @param \Magento\Quote\Model\Quote\Item\Repository $subject
* @param \Magento\Quote\Model\Quote\Item $result
*/
public function afterSave(\Magento\Quote\Model\Quote\Item\Repository $subject, $result){
$newItem = ObjectManager::getInstance()->get('\Magento\Quote\Api\Data\CartItemInterface');
$newItem->setQuoteId($cartId);
$newItem->setQty(1);
$newItem->setSku($discount);
$newItem->getExtensionAttributes()->setIsDelete()
}
So i want to add "is delete" attribute to quote item api rest response.
