Rails - May 2008 - Generating file for download from controller method on demand

Hello

I''d like to implement in my app functionality of generating text files
for download (like excel files etc.) generated on demand (user clicks
"download a copy" and rails app should generate it and let user
download, or at least start downloading by user)

Is there any possibility to do it as simple as possible? :)

Best regards and thank you in advance for your responds
Pawel K.

that''s my controller code for downloading a pdf file generated in the 
method write_invoice_pdf with pdf-writer

def pdf
  write_invoice_pdf
  send_file(File.join(PDF_PATH_INVOICES, "result.pdf"), :filename
=>
''result.pdf'', :disposition =>
''attachment'', :type => ''application/pdf'')
end

that''s basically all to it. generate the file, store it
''somewhere'',
PDF_PATH_INVOICES in that case defines the target folder and is set in 
development.rb.
after that it needs only to be sent and the browser will open the dialog 
to ask if you want to open it or save to disk.
