Hello:
when i use Prawn to generate pdf file for download, i got a blank pdf
file, can someone tell me why?
require 'prawn'
class DownloadController < ApplicationController
def download_pdf
send_data(generate_pdf, :filename => 'test.pdf', :type =>
'application/pdf')
end
private
def generate_pdf
Prawn::Document.new do |p|
p.text 'Document Name', :align => 'center'
p.text 'Address: address'
p.text 'text end'
end.render
end
end
routes.rb:
map.download '/download', :controller => 'download', :action =>
'download_pdf'
when i type http://localhost:3000/download in firefox, i got a blank pdf
file, no one text in this file why?
