Enums with Rails Admin

enums.rb

# This might not be the best way, it might be improved in more
# recent versions of Rails Admin, but this seems to work okay
# for me.

class SomeModel < ActiveRecord::Base

  enum :some_enum => {
    :some_key => 0
  }

  rails_admin do

    field :some_enum, :enum do
      searchable false

      enum do
        SomeModel.some_enums.map { |k,_| [k.titleize, k] }
      end

      pretty_value do
        if bindings[:object]
          bindings[:object].send(:some_enum).titleize
        end
      end

      def form_value
        bindings[:object].some_enum
      end
    end

  end
