I am mapping devices. Led is a light emitting diode. BluetoothDetector is a modular microcontroller that holds the logic and is 

I have an ARobject BluetoothDetector which inherits (but is NOT STI) from ArduinoBt.

p = BluetoothDetector.first; p
=> #<BluetoothDetector id: 1, name: "the main controller device">
>> p.children << BluetoothDetector.create(:name=>'slave device')
=> [#<BluetoothDetector id: 45, name: "slave device">]
>> DeviceConnection.first
=> #<DeviceConnection id: 5, child_id: 45, child_type: "ArduinoBt", parent_id: 1, parent_type: "ArduinoBt">

# reload environment

p.children << Led.create
=> [
    #<ArduinoBt id: 45, name: "slave device"l>, 
    #<Led id: 225, brightness: nil, amperage: nil, wavelength: nil>
   ]

Hmmm. I can't seem to override the "child_type" class_name while saving.
