#process(container:, options: {}) ⇒ Result

Returns status and any material alerts.

Parameters:

  • container (Quote, Order, RoomConfiguration) —

    the resource to check

  • options (Hash) (defaults to: {}) —

    shared check options passed by Item::Materials::Check

Options Hash (options:):

  • :for_www (Boolean) —

    whether the check runs for the public site

  • :for_cart (Boolean) —

    whether the check runs for the cart

Returns:

  • (Result) —

    status and any material alerts
