Ruby on rails file download using form submit

I have a page where I upload a list of users to an action upload data. There on success/failure it lists me the list of invalid users. This is a one time action the lsit of users is not saved to database. I need to be able to write these user list to a file and allow the user to download this file. I do not have a clue on how to proceed. Any help would be appreciated.

1. require the CSV library to controller

require 'csv'

2. Code in controller

    def export_to_csv
       #get all invalid users here and then modify according to yoou logic       
        @users = User.find(:all)
        csv_string = CSV.generate do |csv|
             csv << ["Id", "Name", "status","Role"]
             @users.each do |user|
               csv << [user.id, user.name, user.status, user.role]
             end
        end         

       send_data csv_string,
       :type => 'text/csv; charset=iso-8859-1; header=present',
       :disposition => "attachment; filename=users.csv" 
    end
