Subject: Re: [Castle-users] Using ActiveRecord with Legacy Database
Which part sounds awkard? Having domain object specify specific validators and combine that with a contextual validation? or something else
My goal is to perform validation as simple as possible given validation specific to a model as well as cross-domain validation.
How have you handled that in the past? Did you just create a Validation service that accepts domain objects?
As always, I welcome your criticism :-)
