In your controller action method, instead of using render, use either send_data or send_file, e.g.
send_data("name,age\nfred,23\njoe,16\n", :filename => "data.csv", :type => "text/csv", :disposition => "attachment")
The filename option will be used as a suggestion to the user for the name of the downloaded file, type is the mimetype, and disposition of attachment tells the browser to download rather than display the downloaded file.
The default value for the disposition option is "attachment" so you don't really need to specify it, if you set it to "inline" then the browser will display the file rather than downloading it.
The send_file method works similarly except that the first argument is a string containing a path to a file on the server to be downloaded, and there are two more options to control buffer sizes and whether or not the file is sent as a stream or in chunks.
