[MacRuby-devel] Create new Core Data Instances

Hi List, I've successfully created a core data entity with some attributes. I'm displaying object in a NSTableView and I was able to add new instances by calling the entities array controller add: action. The last hour I tried to figure out how to add/create a core data entity in ruby code without using the interface builder. I tried to instantiate a new object like this: MyEntity.new but I always get the following error: Failed to call designated initializer on NSManagedObject class 'MyEntity' What's the proper way of doing this? For rails-devs: I'm looking for something like: a = MyARObject.new a.attribute1 = "test" a.attribute2 = "test2 a.save Regards, Timo -- twitter.com/orangeorb
