Question

ActiveRecordBase has both OnSave and OnUpdate but does not have OnCreate, why and how can it be implemented? I’m using IsUnsaved in OnUpdate to determine if this is a Create or an Edit operation. Is there any better way?

Answer 1

There is no OnCreate because ActiveRecord “events” are based on NHibernate’s IInterceptor, and IInterceptor doesn’t have any OnCreate.

However, OnSave is called for new persistent objects only, and OnUpdate only for updates, so there is no need to check IsUnsaved anywhere. Here’s the test that covers this.
