    Metadata details:
    filename: user_reporting.rb
    path of file: ./repos/spree/core/app/models/concerns/spree
    
    the code of the file until where you have to start completion: module Spree
  module UserReporting
    extend DisplayMoney
    money_methods
    
    def report_values_for(report_name, store)
      store ||= Store.default

      completed_orders(store).pluck(:currency).uniq.each_with_object([]) do |currency, arr|
        arr << send("display_#{report_name}", store: store, currency: currency)
      end
    end
