Interface:

            return true;
        }

}

Product repository:

class ProductRepository extends EloquentRepository
{

    public function getModel()
    {
        return ProductModel::class;
    }
}

Product Controller:

class ProductController extends Controller
{

    /**
     * @var \App\Repositories\Product\ProductRepository
     */
    private $_productRepository;


    /**
     * ProductController constructor.
     *
     * @param \App\Repositories\Product\ProductRepository $_productRepository
     */
    public function __construct(ProductRepository $_productRepository)
    {
        $this->_productRepository = $_productRepository;
    }

   public function getProducts()
    {
        return view('products')->with('products',$this->_productRepository->all());
    }
