Thanks so much! So  
`Server.new.custom_fields_fk` is `pfaffmanager_server_id` if I use `pfaffmanager_serfver_id`. So maybe I should use `server_id` and then override as you suggested above.

It looks like `refresh_custom_fields_from_db` is trying to use the wrong names. I don’t quite understand what `_custom_fields.order...` is doing.

I’m going to see what happens if I use `server_id` and if I can then override `custom_fields_fk`
