Exception Type: RelatedObjectDoesNotExist at /dcim/devices/3105/power-outlets/add/
Exception Value: PowerOutlet has no device.

If I remove the 'limit power_port choices to the local device' part of dcim/forms.py, this works perfectly well.

If I comment out the below from PowerOutletForm this works as expected - power_port isn't currently part of PowerOutletCreateForm so this doesn't appear to have a lot of impact currently.

Relevant code introduced in 3d5f85c0ca:

        # Limit power_port choices to the local device
        self.fields['power_port'].queryset = PowerPort.objects.filter(
            device=self.instance.device
        )
