In my custom module, I'm trying to override Magento\Catalog\Model\Layer\FilterList class (more precisely: I want to override function getFilters).

In the module's etc\di.xml there are:

  1. One plugin statement
  2. One preference statement

The plugin is working perfect, while preference is completely ignored.

    <preference for="Magento\Catalog\Model\Layer\FilterList" type="\vendor\module\Model\Layer\FilterList"/>

<type name="Magento\Catalog\Model\Product">
    <plugin name="logProductName" type="\vendor\module\Plugin\ProductName" />

I double checked all class references - all's good. Please let me know what I'm missing.

Thank you very much!

    Why you are overriding this method ? You can use simply plugin feature because this getFilters method is public

  • I know it's public. However, in my case is simplier to use overriding. Any ideas? Commented Nov 10, 2016 at 11:25
  • Just use around plugin and don't call original method($procede() closure) , and do your magic :)

  • Thanks Keyur. Just done it with plugin. I'm not calling the original method. I do my magic ;) - However, I have problem with accessing protected variables. How do I access them? Commented Nov 10, 2016 at 13:51
  • You can define protected variable in your file and Inject \Magento\Catalog\Model\Layer\FilterList into constructor so you can call createAttributeFilter () method

Here is full code to Override Magento\Catalog\Model\Layer\FilterList this class

I can use virtualType method for override instead of preference




<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Pradip_LayerModel" setup_version="0.1.0"/>        


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <virtualType name="categoryFilterList" type="Pradip\LayerModel\Model\Layer\FilterList">
            <argument name="filterableAttributes" xsi:type="object">Magento\Catalog\Model\Layer\Category\FilterableAttributeList</argument>



namespace Pradip\LayerModel\Model\Layer;

 * Override FilterList Class
class FilterList extends \Magento\Catalog\Model\Layer\FilterList
        public function getFilters(\Magento\Catalog\Model\Layer $layer)
            //echo "you can write code changes here"; exit;
            if (!count($this->filters)) {
                $this->filters = [
                    $this->objectManager->create($this->filterTypes[self::CATEGORY_FILTER], ['layer' => $layer]),
                foreach ($this->filterableAttributes->getList() as $attribute) {
                    $this->filters[] = $this->createAttributeFilter($attribute, $layer);
            return $this->filters;

May be below code is work for you.

 <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
     <preference for="Magento\Catalog\Model\Layer\FilterList" type="Vendor\Module\Model\Layer\FilterList"/>

use this instead of

 <preference for="Magento\Catalog\Model\Layer\FilterList" type="\Vendor\Module\Model\Layer\FilterList"/>

and make sure you have to re-compile, or remove var/di, var/generation etc.

and you have to extends this \Magento\Catalog\Model\Layer\FilterList core class in your custom class.
