Re: [MacRuby-devel] attr_accessor on NSManagedObject

I subclassed a Core Data entity Recipe with PPRecipe < NSManaged object, and created accessors for the fields:

class PPRecipe < NSManagedObject attr_accessor :name, :desc, :type, :imagePath, :serves end

but these fields now don't save or display correct after I create objects, and restart the app for example.

The generated accessors are writing to ivars instead of the CoreData store.

What do I need to do to get accessors working for NSManagedObject attributes?

I think what you really need is either: • an attr_dynamic to replicate the behavior of the @dynamic property getters in Objective-C, or, • an attr_coredata (or similar) call in HotCocoa which calls the primitive getters and setters. -Ben
