Validation in AKKA.NET

I have an actor called OrderActor which is the order being created for a customer. I have a validation rule that says If the Product is a computer, allow only one item. This rule should be applied whenever the OrderActor receives a message to add a product.

My question is about the Validation. Should I have a new actor called OrderValidatorActor and this needs to have the OrderActor as the parent actor? In this case, the flow of the events should be The OrderActor sends a message to the OrderValidatorActor which sends a response back to the OrderActor after validation.

Please guide on how to handle validation?

The role/responsibility based object oriented programming principle apply in actor modeling also. The responsibility of validation is thus done in the OrderValidatorActor.

How about this?

  1. Receive an RequestAddItem message in your OrderActor.
  2. OrderActor sends the item details in a ValidateOrderItem message to OrderValidatorActor.
  3. OrderValidatorActor sends either an AddValidatedItem or DenyInvalidItem message to the OrderActor.
