Rails - Jun 2005 - Generate PDFs with Rails

Hello all,

I''m trying to generate a PDF from Rails. I consulted the documentation
here:

http://wiki.rubyonrails.com/rails/show/HowtoGeneratePDFs

but the code doesn''t seem to work. I have the following controller:

require ''pdfwriter.rb''
class FooController < ApplicationController
  def foo
    if @request.env[''HTTP_USER_AGENT''] =~ /msie/i
      @headers[''Pragma''] = ''''
      @headers[''Cache-Control''] = ''''
    else
      @headers[''Pragma''] = ''no-cache''
      @headers[''Cache-Control''] = ''no-cache,
must-revalidate''
    end
    send_data foo_pdf, :filename => "foo.pdf", :type =>
"application/pdf"
    render_without_layout
  end

  private
  def foo_pdf
    pdf = PdfWriter.new
    pdf.newPage
    pdf.writeText(10, 200, ''Text to write'', :fontsize =>
18)
    pdf.writeEnd
  end
end

However, this gives me the following error when running with WEBrick:

#<RuntimeError: bad header ''"%PDF-1.3\n"''.>
["/usr/lib/ruby/1.8/webrick/httputils.rb:143:in

"/usr/lib/ruby/gems/1.8/gems/rails-0.12.1/lib/webrick_server.rb:21:in
`dispatch''", "script/server:48"]

Any help would be appreciated.

Thanks.

Albert

P.S. The Ruby FPDF site seems to be down at the moment, so I haven''t
tried
it yet.
