Magento 2
Using Object Manager
Free Preview
🟢 Good code
/**
* Rather than using Object Manager directly in your code, instantiate objects
* within the constructor of your class. This puts Magento in charge of
* instantiating objects, and makes your code much more compatible with
* third-party code, platform upgrades, & more.
*/
use Magento\Store\Model\StoreManagerInterface;
...
/** @var StoreManagerInterface */
private $storeManager;
/**
* @param StoreManagerInterface $storeManager
*/
public function __construct(StoreManagerInterface $storeManager) {
$this->storeManager = $storeManager;
}
public function execute() {
...
$quote->setWebsite($this->storeManager->getWebsite($websiteId));
...🔴 Bad code
/**
* Direct usage of Object Manager in your code is officially discouraged by
* Magento. Calling the Object Manager inline (as below) circumvents Magento's
* dependency injection layer, which automatically creates objects for you. This
* leads to unsustainable code and is prone to errors during platform upgdates.
*/
public function execute()

$quote->setWebsite(
$this->_objectManager->get(
\Magento\Store\Model\StoreManagerInterface::class
)->getWebsite($websiteId)
);
