Magento 2 – How to Convert Custom Quote Field to Order Field

convertcustom-fieldmagento2quote

I added a new field "management_fee" on table "quote" properly. I add this field on "sales_order" field too.
I would like to update this field on sales_order table while quote is converting to order.

I know how to do with quote items using plugin and Magento\Quote\Model\Quote\Item\ToOrderItem class, but I did not find a class for quote to order.

add the fields to both table quote and sales_order via a setup script in your module.

Then add an event in your module (see below)

 <?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_model_service_quote_submit_before">
            <observer name="quote_submit_before" instance="Vendor\Module\Observer\QuoteSubmitBefore" />
        </event>
    </config>

Finally save the quote data against your order

class QuoteSubmitBefore implements ObserverInterface
{

    /**
     * @param Observer $observer
     * @return void
     */
    public function execute(Observer $observer)
    {
       $quote = $observer->getQuote();
       $order = $observer->getOrder()

        $order->setData('field_custom', $quote->getData('field_custom'));      
    }
}

You can use like this in your function

    protected $quoteRepository;
public function __construct(\Magento\Framework\Model\Context $context, 
        \Magento\Quote\Api\CartRepositoryInterface $quoteRepository
    )
{       
    $this->quoteRepository = $quoteRepository;
    parent::__construct($context, $registry);
}

public yourfunction(){
    $quote = $this->quoteRepository->getActive($id);
      $quote->collectTotals();
      $count = (int)$quote->getitemsQty();
      $total = $quote->getgrandTotal();
}

Magento – Custom checkout field doesn’t save the value to quote

Probably the problem lies in misunderstanding the power of extension attributes. I assume you think that if you have added extension_attribute configuration in an xml file + you created additional columns in table schema Magento will do the rest. Unfortunately not.

Extension attributes makes interfaces extensible but handling of the logic for these additional attributes lies in hands of developer.

You must take care on how attributes are kept in object's data and how are saved or processed.

So, you have to do, as additional steps:

handle passing data from a checkout form to your extension attribute
handle saving those data eg. by making a plugin for a quoteRepository::save() method

Implementation depends on you.

What you get by using extension attributes is, among others, the ability to call defined methods like $quote->getExtensionAttributes()->[get/set]YourAttribute()

It helps developers because explicit public interface exists.

Magento's mechanism helps extending iterfaces And developer role is to implement and handle logic of these attributes
