refund using CQRS design pattern

[mr_david]

Hi all,

I'm trying to make a refund base on the docs provided for prestashop 1.7.7. 

$command = new IssuePartialRefundCommand (
      $orderId,
      $refund_information['refund_items'],
      $refund_information['shipping_amount'],
      (bool)$refund_information['restock'],
      (bool)$refund_information['credit_slip'],
      (bool)$refund_information['voucher'],
      (int)$refund_information['voucher_refund_type'], 
);

$commandBus = $this->get('prestashop.core.command_bus');
$commandBus->handle($command);

But I does not work, it seems that $commandBus is null. Is there anything more I have to configure to load the command_bus ?

Could you find a solution? I have the same problem and I don't know how to fix it

Where did you call it ?

Because there are 3 service containers on PrestaShop :

1. BO Symfony (with CommandBus) only available on Symfony based controllers
2. BO Legacy (no CommandBus) available on all old controllers (module configuration page & ModuleAdminController)
3. FO (no CommandBus) (FrontController or ModuleFrontController)

So you can only use it in a Symfony controller

In my case my file is in the directory of my module (controllers/admin/refunds.php), and that file is like this

<?php

include('../../../../config/config.inc.php');
include('../../../../init.php');

use PrestaShop\PrestaShop\Core\CommandBus\CommandBusInterface;
use PrestaShop\PrestaShop\Core\Domain\Order\Command\IssueStandardRefundCommand;

class Refunds extends Module
{
  public function createRefundTotal()
  {
    $order         = new Order($_GET['order_id']);
    $order_details = OrderDetail::getList((int)$_GET['order_id']);

    $refunds            = [];
    $refundShippingCost = ($_POST['shipping'] == 'true') ? true : false;
    $orderId            = $_GET['order_id'];
    $generateCreditSlip = true;
    $generateVoucher    = true;
    $voucherRefundType  = '1';

    for ($i = 0; $i < count($order_details); $i++)
    {
      $quantity = $order_details[$i]['product_quantity'] - $order_details[$i]['product_quantity_refunded'];

      if($quantity > 0)
      {
        $refunds[(int)$order_details[$i]['id_order_detail']] =
        [
          'quantity' => (int)$quantity
        ];
      }
    }

    $command = new IssueStandardRefundCommand(
      $orderId,
      $refunds,
      $refundShippingCost,
      $generateCreditSlip,
      $generateVoucher,
      $voucherRefundType
    );

    $this->commandBus->handle($command);
  }
}

This way it doesn't work and it gives me the following error

Notice: Undefined property: Refunds::$commandBus

Obviously the error is because the commandBus does not exist, but how can I use it ?, or if there is another way to generate the return of the order

You should create a Symfony admin controller on your module to use Symfony container and retrieves CommandBus
