Hello.
I am trying to remove the commented lines.
However when I remove it and compile the custom module from Terminal, it receives an error.
Errors during compilation:
Missed required argument checkoutSession in parent::__construct call.
I wonder why it happens. I only deleted unused code such as:
//use Magento\Framework\View\Result\PageFactory
This is the beginning of my class.
use \Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Controller\ResultFactory;
//use Magento\Framework\View\Result\PageFactory;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
//use Magento\Framework\Controller\Result\JsonFactory;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Framework\Serialize\SerializerInterface;
class UpdatePost extends \Magento\Checkout\Controller\Cart
{
/**
* @var \Magento\Framework\Registry
*/
protected $_registry;
protected $eventManager;
protected $_checkoutSession;
protected $_logger;
protected $_customerSession;
protected $jsonResultFactory;
protected $jsonHelper;
protected $context;
protected $resultFactory;
protected $scopeConfig;
protected $request;
protected $data;
protected $_layout;
public function _construct(
\Magento\Checkout\Model\Session $checkoutSession,
\Magento\Framework\Registry $registry,
\Magento\Framework\Event\Manager $eventManager,
\Magento\Checkout\Model\Cart $cart,
\Psr\Log\LoggerInterface $logger,
\Magento\Customer\Model\Session $customerSession,
Context $context,
array $data = [],
\Magento\Framework\Json\Helper\Data $jsonHelper,
\Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
\Magento\Framework\View\LayoutInterface $layout
) {
$this->_checkoutSession = $checkoutSession;
$this->_registry = $registry;
$this->eventManager = $eventManager;
$this->cart = $cart;
$this->_logger = $logger;
$this->_customerSession = $customerSession;
$this->context = $context;
$this->jsonHelper = $jsonHelper;
$this->data = $data;
$this->scopeConfig = $scopeConfig;
parent::__construct($context, $data);
$this->_layout = $layout;
}
