rails admin uninitialized constant Country::Person

When I click on Countries in rails_admin navigation I get 

NameError in RailsAdmin::Main#index

uninitialized constant Country::Person

raise NameError.new("uninitialized constant #{candidates.first}", candidates.first)

I'm using User model but not Person. I think I need to configure it somehow. But where to do this?

here's my rails admin initializer

  ## == Devise ==
   config.authenticate_with do
     warden.authenticate! scope: :user
   end
   config.current_user_method(&:current_user)

  ## == Cancan ==
   config.authorize_with :cancan 

  ### More at https://github.com/sferik/rails_admin/wiki/Base-configuration

  config.model "User" do
      edit do
        field :admin
        field :username
        field :email
        field :password
      end
    end

  config.actions do
    dashboard                     # mandatory
    index                         # mandatory
    new
    export
    bulk_delete
    show
    edit
    delete
    show_in_app

    ## With an audit adapter, you can add:
    # history_index
    # history_show
  end

I had this issue too, but it wasn't caused by a lost association. I had incorrectly pluralized my model's name when I created it: it was Things instead of Thing.

I fixed it manually by changing the class name in things.rb from Things to Thing and renaming the file to thing.rb.

The problem was with my model. it used to be

class Country < ActiveRecord::Base
  has_many :people
end
