Steps to Reproduce

Can be reproduced on the beta demo

1. Create a device type
2. Add an inventory item to the type
3. Add a second inventory item that's a child of the first inventory item
4. Try to create a device using that device type

You will get the following error:

<class 'django.core.exceptions.FieldError'>

Cannot resolve keyword 'device' into field. Choices are: _name, child_items, component, component_id, component_type, component_type_id, created, description, device_type, device_type_id, id, label, last_updated, level, lft, manufacturer, manufacturer_id, name, parent, parent_id, part_id, rght, role, role_id, tree_id
