I appreciate all the feedback on this but the more I thought about it, the more I realised I wasn't really sure what I was asking for.
I think I meant for Hobo to detect if the rich-type had particular callback methods and, if so, to hook them into the model's read and write methods for that field. In other words, to do automatically, what I was doing in my example. This behaviour could be confusing though because the application author might have some other valid reason for wanting to override those reader and writer methods. I don't know if there's a resilient way to do this. Then I started to think that what I really wanted was a hook into the view/controller layers. The <view/> tag and I think the <input/> tags already call to_s on the object being displayed. So by overriding that in the rich-type we're half-way there. If we could have a from_s method on the rich type that was called when data was written we could do the conversion there. Only, from_s would have to be a class method or a constructor because the rich-types inherit from the base types. At this point I read about ActiveRecord's Aggregate functionality, which seems to overlap this somewhat, and got really confused. Which is why I haven't logged an enhancement request on lighthouse. I'm getting by quite nicely, for now, with my original solution: store it as an integer and convert it in the field getters and setters. /Ritchie --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hobo Users" group.
