how can i add download functionality

Hello friends

i have to generate a text file when clicked on a button and when this
file got generated than i have to show a download dialog box so that
user can download this text file on his computer, can any body gives any
snippet of code or any idea how can i add this download functionality.

Thanks

your download dialog should simply link to an action that uses send_file
to send the text file:

send_file(File.join(FILE_PATH, file_name), :filename => 'something.txt',
:disposition => 'attachment', :type => 'text/plain'
