(PRAWN) PDF created but PDF won't download

Rails
1

I can create a PDF document using PRAWN, but when I try to download as
an attachment via a link, nothing appears to happen. When I go into the
/tmp/pdfs/ directory of my rails app, I can see the created PDF
document.

Can anyone see why the pdf doc will not download?

Thanks,

Frank

CONTROLLER

def make_pdf
filename = ‘prawn.pdf’

 pdf = Prawn::Document.new
 pdf.text("Prawn Rocks")
 pdf.render_file('tmp/pdfs/prawn.pdf')

 send_file "#{RAILS_ROOT}/tmp/pdfs/#{filename}", :type =>

‘application/pdf’, :disposition => ‘attachment’
end

Have you checked the html of the page to see if the link looks correct
(View, Page Source or similar in your browser). If it does look ok
does it work if you type it into browser directly?

That worked Fred. Thank you both for your help.

Because you’ve got a link_to_remote - that just creates a Ajax.Request
object that fetches the data and then ignores it - use a regular link.
