Here's how you should do it:
class DownloadController < ApplicationController
def download_pdf
send_data(generate_pdf, :filename => 'test.pdf', :type => 'application/pdf')
end
private
def generate_pdf
document = Prawn::Document.new do |p|
p.text 'Document Name', :align => 'center'
p.text 'Address: address'
p.text 'text end'
end.render
send_data document, :type => 'application/pdf'
end
end
