pdf-file tot desktop with pdf/writer problem

Hi, I'm using pdf/Writer to generate a pdf-file, but whatever I do, it gets saved in folder of my app, and not on the users desktop.

I've used

   pdf = PDF::Writer.new            pdf.select_font "Times-Roman"            pdf.text "Hello.pdf", :font_size => 12, :justification => :left            File.open("hello.pdf", "wb") { |f| f.write pdf.render }

and Ive used

_pdf = PDF::Writer.new           _pdf.select_font "Times-Roman"           _pdf.text "Hello, Ruby.", :font_size => 72, :justification => :center

          send_data _pdf.render, :filename => "hello.pdf",                     :type => "application/pdf"         end

Both save to my folder on the server, but no download or saving to the desktop. I must me missing something here. (The action is in my general controlller, which has a layout. I don't know if that has anything to do with it, but I mention it just in case...)

Could someone help me out on this simple one? Thanks in advance. Rudy

That's the appropriate behavior. If you want it to go to the user, you need to use send_file after the file is written to the folder on the server. Note that send_file counts as a render so you'll need to structure your app accordingly to get the UI behavior you want.

Hi Bill

When I do

pdf = PDF::Writer.new            pdf.select_font "Times-Roman"            pdf.text "Hello.pdf", :font_size => 12, :justification => :left            pdf.save_as "hello.pdf"            send_file "hello.pdf", :filename => 'hello.pdf', :type => 'application/pdf'

the last line on the logfile is

Streaming file hello.pdf

But nothing appears on the desktop. I just don't get it.

Are you accessing that pdf controller in a web browser? The user
should go to the controller url, be asked to save the pdf, select the
place to save it, then the pdf streams to them.

Hi Andy thanks for answering. Sorry about this newbiething, but I don't exacltly understand your question.

My user clicks in a browser on a specific icon when he wants some info saved as a pdf-file. This icon invokes an action, that sits in de main admin_controller. There is no rhtml or anything else connected to the action.

The strange thing is that I used the same bit with Spreadsheet/excel, and that works fine.

First, nothing will appear on the desktop without user intervention. The send_file should cause a "view or save" dialog to be displayed on the visitor's system and then, assuming they choose 'save', they go from there.

I assume you're not seeing the 'view or save' dialog, which means you've got a problem. I don't see anything obviously wrong with your code. I normally use explicit paths, but I'm pretty sure if Rails couldn't find the file it would throw an error. So that's probably not it. I've not used pdf.save so my own investigation would start there. What I do to create / save a file (I assume you've checked and you actually have a viewable pdf file?) is: pdf = PDF::Writer.new ... File.open("#{RAILS_ROOT}/private/#{filenametouse}", "wb") { |f| f.write pdf.render}

then I'm doing a redirect to another controller and there I do:

send_file("#{RAILS_ROOT}/private/#{filetosend}", :filename => "#{suggestfile}.pdf", :stream => true)

If moving to an explicit file creation like above didn't help, I'd go to my sandbox and try getting send_file to work on some existing, known-good files.

Sorry I can't be more help, Bill

Hi Bill and Andy

Silly ME! After using some code of a spreadsheetdownload that worked and was within the same controller, I got the same result. Streaming but no file. So then lightning struck: must have something to do with triggering the action!

I just write this down here as a sort of contribution. One day in the future someone may face the same problem. I've found so many solutions for problems on this list the past few months, that its the least I can do.

I was launching the action in the view with a remote_form_for. (duh...) Once I changed that into a form_for everything worked like a charm. So easy to overlook, so difficult to trace. Hope this helps someone sometime.

Hi Ruby,

Glad to hear you got it figured out. Nice form, too.

Best regards, Bill
