getResource is deprecated, what is the alternative?

Question

getResource() is deprecated so my question is what do I need to use instead to be future proof for next updates.

I use this function like below in the catalog list.phtml

$seedBank = $_product->getResource()->getAttribute('brand')->getFrontend()->getValue($_product);

Answer 1

You can get product custom attribute option label directly as below:

$_product->getAttributeText('brand');

This will return label of product selected brand.

Answer 2

Have an instance of \Magento\Catalog\Mode\ResourceModel\Product as a dependency for your class and call methods from that class.

/**
 * @var \Magento\Catalog\Mode\ResourceModel\Product
 */

private $productResource;

public function __construct(
    ....
    \Magento\Catalog\Mode\ResourceModel\Product $productResource,
    ....
) {
    ....
    $this->productResource = $productResource;
    ....
}

now, in the methods where you need the value, let's say $_product is the product instance you can do this:

$seedBank = $this->productResource()->getAttribute('brand')->getFrontend()->getValue($_product);
