Cannot override class RuleProductPricesPersistor in Magento 2

Question

I'm trying to override following class

Magento\CatalogRule\Model\Indexer\RuleProductPricesPersistor

Using below code

<preference for="Magento\CatalogRule\Model\Indexer\RuleProductPricesPersistor"
                type="Vendor\Module\Model\Indexer\RuleProductPricesPersistor" />

But I'm getting following error

Type Error occurred when creating object: Magento\CatalogRule\Model\Indexer\ReindexRuleProductPrice, Argument 5 passed to Magento\CatalogRule\Model\Indexer\ReindexRuleProductPrice::__construct() must be an instance of Magento\CatalogRule\Model\Indexer\RuleProductPricesPersistor, instance of Vendor\Module\Model\Indexer\RuleProductPricesPersistor given, called in /var/www/html/MagentoCE230/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 116 [] []

I tried to clear generation folder and also ran setup:di:compile command. But it didn't work.

Answer 1

Vendor\Module\Model\Indexer\RuleProductPricesPersistor.php

Your child class should be like this

<?PHP

 use Magento\CatalogRule\Model\Indexer\IndexerTableSwapperInterface as TableSwapper;
 use Magento\Catalog\Model\ResourceModel\Indexer\ActiveTableSwitcher;
 use Magento\Framework\App\ObjectManager;

class RuleProductPricesPersistor extends \Magento\CatalogRule\Model\Indexer\RuleProductPricesPersistor
{

    public function __construct(
        \Magento\Framework\Stdlib\DateTime $dateFormat,
        \Magento\Framework\App\ResourceConnection $resource,
        ActiveTableSwitcher $activeTableSwitcher,
        TableSwapper $tableSwapper = null
    ) {
        parent:: __construct($dateFormat ,$resource , $activeTableSwitcher, $tableSwapper ;);
    }

    // add overrided Functions Here 

}

Answer 2

Your RuleProductPricesPersistor.php code must look like this.

<?php
namespace Vendor\Module\Model\Indexer;

use Magento\CatalogRule\Model\Indexer\IndexerTableSwapperInterface as TableSwapper;
use Magento\Catalog\Model\ResourceModel\Indexer\ActiveTableSwitcher;
use Magento\Framework\App\ObjectManager;

class RuleProductPricesPersistor extends \Magento\CatalogRule\Model\Indexer\RuleProductPricesPersistor
{
   public function __construct(
        \Magento\Framework\Stdlib\DateTime $dateFormat,
        \Magento\Framework\App\ResourceConnection $resource,
        ActiveTableSwitcher $activeTableSwitcher,
        TableSwapper $tableSwapper = null
    ) {
        parent:: __construct($dateFormat ,$resource , $activeTableSwitcher, $tableSwapper);
    }
}
