In magento 2, using Preference Configurable.php file is not simply override, Is this is magento 2 bug?

I have override simply using preference method inside di.xml file but its not override.

I want to override function getJsonConfig() from file. Using only Simply override method of magento 2. Code for di.xml file

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\ConfigurableProduct\Block\Product\View\Type\Configurable" type="Package\Configurable\Block\Product\View\Type\Configurable"/>    
</config>

Is there any trick or method to override Configurable.php file?

Thanks.

    You can use plugin for this. – Sohel Rana Jun 22 '16 at 11:24
  • without plugin we cant do it? this is simple block file but not override, what is the issue behind this? – Rakesh Jesadiya Jun 22 '16 at 11:27
  • Whole file overwrite is not a good practice. I just add a plugin for you. – Sohel Rana Jun 22 '16 at 11:31

VendorName/ModuleName/etc/frontend/di.xml


<?xml version="1.0"?>

    <type name="Magento\ConfigurableProduct\Block\Product\View\Type\Configurable">
        <plugin name="vendor_configurable_product_configurable" type="VendorName\ModuleName\Block\ConfigurableProduct\Product\View\Type\Configurable" sortOrder="1"/>
    </type>
</config>



namespace VendorName\Module\Block\ConfigurableProduct\Product\View\Type;

use Magento\Framework\Json\EncoderInterface;
use Magento\Framework\Json\DecoderInterface;
class Configurable
{

    protected $jsonEncoder;
    protected $jsonDecoder;

    public function __construct(
        EncoderInterface $jsonEncoder,
        DecoderInterface $jsonDecoder
    ) {

        $this->jsonDecoder = $jsonDecoder;
        $this->jsonEncoder = $jsonEncoder;
    }

    public function aroundGetJsonConfig(
        \Magento\ConfigurableProduct\Block\Product\View\Type\Configurable $subject,
        \Closure $proceed
    )
    {
        $config = $proceed();
        $config = $this->jsonDecoder->decode($config);
        $config['url'] = 'sample_url';
        return $this->jsonEncoder->encode($config);
    }
}

You can use after plugin following way:


namespace VendorName\Module\Block\ConfigurableProduct\Product\View\Type;

use Magento\Framework\Json\EncoderInterface;
use Magento\Framework\Json\DecoderInterface;
class Configurable
{

    protected $jsonEncoder;
    protected $jsonDecoder;

    public function __construct(
        EncoderInterface $jsonEncoder,
        DecoderInterface $jsonDecoder
    ) {

        $this->jsonDecoder = $jsonDecoder;
        $this->jsonEncoder = $jsonEncoder;
    }

    public function afterGetJsonConfig(
        \Magento\ConfigurableProduct\Block\Product\View\Type\Configurable $subject,
        $config
    )
    {
        $config = $this->jsonDecoder->decode($config);
        $config['url'] = 'sample_url';
        return $this->jsonEncoder->encode($config);
    }
}

  • Any reason why using the around instead of the after ? – Raphael at Digital Pianism Jun 22 '16 at 11:45
  • No reason, You can use after and around both plugin. – Sohel Rana Jun 22 '16 at 11:51
  • How to do above method using after plugin with same content in above function? – Rakesh Jesadiya Jun 22 '16 at 12:22
  • Its required in after plugin method to pass second parameter as $config? – Rakesh Jesadiya Jun 22 '16 at 13:27
  • @Rakesh The second parameter [$config] is the result of the original method call. – Keyur Shah Jun 22 '16 at 13:46
