Ha! You did it! Thanks so much. I switched it to `server_id` and then did this in my `server.rb` model:

```ruby
    def custom_fields_fk
      @custom_fields_fk ||= "server_id"
    end

```

As long as that’s going to override that only for this model and not break `user_custom_field` and friends I think I should be ready to start beating myself over the head again on [Best way to enforce permissions--controller or constraint?](https://meta.discourse.org/t/best-way-to-enforce-permissions-controller-or-constraint/176113). And then I can add routes to do stuff like fill my new custom fields with . . . something.

I can’t thank you enough. You likely saved me a whole day. I owe you a 🍺!
