pdf writer not finding public directory

Hi all,

I'm attempting to learn about PDF::Writer. I've written a brief test program to play with the concepts. Here is the code:

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

    pdf.save_as("#{@request.relative_url_root}/pdf/hello.pdf")

I keep getting the following error:

(Note: schedprog is an alias to my rails application directory (which is /pds)

Errno::ENOENT (No such file or directory - /schedprog/pdf/hello.pdf):

I've tried a number of options, but no matter what I do I get the above

error message. I've checked the application's public directory and know the pdf directory exists and I even set permissions to 777 just to make sure my program could do anything.

What am I missing? Any help would be appreciated.

You have two different urls you have to keep in mind. Your site url, which is handled by your request, and you url on your server, or more accurately your path. When you ask you’re request what the url is, it’s looking at what path the browser would be looking at. You need to be worried about the server side. It should be just as easy as setting your path to ./public/pdf/hello.pdf, assuming that you’re trying to get into your local project’s public file.

I don't see what the public directory has to do with it - if /schedprog/pdf/hello.pdf is what the error message says, that's what it's looking for - the error message doesn't mention 'public', so it isn't looking there.

/ - root directory /pdfs - your rails application root directory (seems a bit odd to have this under /, but never mind)          /app - your model classes etc          /pdf - this is where PDF:;Writer is trying to put the PDF         /public - the rail public dir                     /pdf this is where you want the PDFs to go

the only files that are publicly accessible by the server are files in your public folder. That’s why your stylesheets, javascripts, and images folders are all in this folder. So if you go to http://www.mysite.com/images/image1.jpg, it is looking on the server at location rails_app/images/image1.jpg. So if you want to be able to get to a pdf by going to htttp://www.mysite.com/pdfs/pdf1.pdf, you would have to save pdf1.pdf in rails_app/pdfs/pdf1.pdf

Thanks, Mike.

I finally got there. My problem was with a redirect I was doing
after I created the pdf file. I discovered I was pointing to the
wrong place. So for a while I was looking in the wrong place for a
solution. Wasn't quite awake as I thought I was on this one. :slight_smile:
