    the code of the file until where you have to start completion: module Workarea
  module Admin
    module SegmentsHelper
      def segment_rule_types_options
        Workarea.config.segment_rule_types.map do |string|
          rule = string.constantize
          [t("workarea.admin.fields.#{rule.slug}", default: rule.slug.to_s), rule.slug]
        end
      end
