Magento 2: How to override model resource configurable file

Question

I have created a custom module.

di.xml

< type name="Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable"> < plugin name="ptgConfigurableProduct" type="ModuleName\Extendfiles\Plugin\Model\ResourceModel\Product\Type\Configurable" sortOrder="1" /> < /type>

Path: /ModuleName/Extendfiles/Model/ResourceModel/Product/Type/ Configurable.php

namespace ModuleName\Extendfiles\Plugin\Model\ResourceModel\Product\Type;

class Configurable extends \Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable {

}

Function

public function afterGetAttributeOptions($superAttribute, $productId){

 $scope = $this->getScopeResolver()->getScope();
 $select = $this->getConnection()->select()->from(
 ['super_attribute' => $this->getTable('catalog_product_super_attribute')],
 [
 'sku' => 'entity.sku',
 'product_id' => 'product_entity.entity_id',
 'attribute_code' => 'attribute.attribute_code',
 'value_index' => 'entity_value.value',
 'option_title' => $this->getConnection()->getIfNullSql(
 'option_value.value',
 'default_option_value.value'
 ),
 'default_title' => 'default_option_value.value',
 ]
 )->joinInner(
 ['product_entity' => $this->getTable('catalog_product_entity')],
 "product_entity.{$this->getProductEntityLinkField()} = super_attribute.product_id",
 []
 )->joinInner(
 ['product_link' => $this->getTable('catalog_product_super_link')],
 'product_link.parent_id = super_attribute.product_id',
 []
 )->joinInner(
 ['attribute' => $this->getTable('eav_attribute')],
 'attribute.attribute_id = super_attribute.attribute_id',
 []
 )->joinInner(
 ['entity' => $this->getTable('catalog_product_entity')],
 'entity.entity_id = product_link.product_id',
 []
 )->joinInner(
 ['entity_value' => 'catalog_product_entity_int'],
 implode(
 ' AND ',
 [
 'entity_value.attribute_id = super_attribute.attribute_id',
 'entity_value.store_id = 0',
 "entity_value.{$this->getProductEntityLinkField()} = "
 . "entity.entity_id",
 ]
 ),
 []
 )->joinLeft(
 ['option_value' => $this->getTable('eav_attribute_option_value')],
 implode(
 ' AND ',
 [
 'option_value.option_id = entity_value.value',
 'option_value.store_id = ' . $scope->getId(),
 ]
 ),
 []
 )->joinLeft(
 ['default_option_value' => $this->getTable('eav_attribute_option_value')],
 implode(
 ' AND ',
 [
 'default_option_value.option_id = entity_value.value',
 'default_option_value.store_id = ' . \Magento\Store\Model\Store::DEFAULT_STORE_ID,
 ]
 ),
 []
 )->where(
 'super_attribute.product_id = ?',
 $productId
 )->where(
 'option_value.value != "N/A"',
 $productId
 )->where(
 'attribute.attribute_id = ?',
 $superAttribute->getAttributeId() $attributeId
 );
 return $this->getConnection()->fetchAll($select);
 }

Getting below error for this code

$superAttribute->getAttributeId()

, Fatal error: Call to undefined method Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable\Interceptor::getAttributeId()

• Suresh Chikani: Are you working on developer mode?
• Jimit Bhavsar: yes, it's already in developer mode, and i have already try with commands
• Suresh Chikani: Have you added error_reporting(E_ALL); ini_set('display_errors', 1); this code to index.php ?
• Jimit Bhavsar: Still public function not working and also not showing any error
• Suresh Chikani: Did you got solution?

Answer 1

As per as your code, you have to try to use Plugin as you have using afterGetAttributeOptions which after plugin method on getAttributeOptions.

But, at di.xml you have tried override Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable

In magento2 Plugin & Preference two different things. See Magento2: what is the basic difference between plugin and preference?

At the single word, PLugin can change only the public functions behavior of a class. Where Preference Can change the behavior of any functions of class.

So, to your case, if want to change out the behavior of getAttributeOptions method then you can use after/around/before the plugin method.

Then that case you have to define your class at plugin by below code at your di.xml.

<config>
...
 <type name="Magento\ConfigurableProduct\Model\ResourceModel\Product\Type\Configurable">
 <plugin name="{pluginName}" type="Module\Namespace\Model\ResourceModel\Product\Type\Configurable" sortOrder="1" />
 </type>
..
</config>

If you rewrite the class using Preference the class then That case, you cannot use afterGetAttributeOptions,beforeGetAttributeOptions,aroundGetAttributeOptions as, those method are plugin method.

Update

UNDERSTAND form chat

from the chat, you have to use plugin on Magento\ConfigurableProduct\Model\ResourceModel\Attribute\OptionSelectBuilder and create create after plugin over getSelect

di.xml

 <type name="Magento\ConfigurableProduct\Model\ResourceModel\Attribute\OptionSelectBuilder">
 <plugin name="{pluginName}" type="Module\Namespace\Plugin\ResourceModel\Attribute\OptionSelectBuilder" sortOrder="1" />
</type>

*Plugin Class

<?php
namespace Module\Namespace\Plugin\ResourceModel\Attribute;
class OptionSelectBuilder
{
 public function afterGetSelect(
 \Magento\ConfigurableProduct\Model\ResourceModel\Attribute\OptionSelectBuilder $subject,
 $result
 ){
 {
 return $result->where( 
 'option_value.value != "N/A"', 
 $productId 
 );
 }
}
