sorting belongs to association field

[John Gesimondo]

Hey everyone. I'm trying to do something seemingly simple and can't figure it out. 

An article belongs to a state. When editing the article, I want the states list to be in alphabetical order (by :name). But they are appearing by :id desc.

I have tried 

• setting a default_scope on the state model to order(:name)
  
• overriding the column in rails admin config (see below)

  config.model Article do

    list do; end

    export do; end

    show do; end

    edit do

      field :title

      field :state do

        sortable :name

      end

      field :school

      ...

    end

    create do; end

    update do; end

  end

No matter what I do, the states always appear id desc.

Any suggestions?

John
