Best way for two models in one controller?

Hi everyone,
My question is about following: I have two tables, products and products_description. First holds the general information like price and article number of the products, the description the textual description for each language, so 1:n (like 1 product can have many descriptions in different languages).
So I have controller "Products" and two models for each table.
When I like to query ALL product info in one call.... like general information plus description and details, what do I do best?

Example. Or create new class ProductManager with new methods.

PHP Code:

$products = model(ProductsModel::class)->withDescription()

I am probably not experienced enough for this, but how do I define withDescription? Is it a model function that includes the products_description model?

PHP Code:

class ProductModel extends Model
{
    public function withDescription() {
        return $this->join('products_description', 'products.id = products_description.product_id', 'LEFT')
            ->where('products.id', 1);
    }

}
