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:
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
