    grids:
        sylius_admin_product:
            driver:
                name: doctrine/orm
                options:
                    class: "%sylius.model.product.class%"
                    repository:
                        method: createListQueryBuilder
                        arguments: ["expr:service('sylius.context.locale').getLocaleCode()"]
