- Ruby FPDF on Ruby on Rails
I have been tinkering with Ruby FPDF for a client all night. I found the examples for it to lack in some real-world examples, so I have taken the example from the RubyOnRails wiki and added a bit more to it. I have added things like an image, links and made a generic letter template. (just an example). I didn’t get into the header/footer functions yet, may do that later.
If you are not sure how to use Ruby FPDF, check out the FPDF documentation.
Just download Ruby FPDF and unpack the archive in your libs directory.
To get Railst to load fpdf, I added this to environment.rb:
ADDITIONAL_LOAD_PATHS.concat%w( app app/models[..snip...] lib/fpdf).map{|dir|"#{RAILS_ROOT}/#{dir}"}.select{|dir|File.directory?(dir)}At the top of my controller that uses this lib, I added:require'fpdf'When I browse to this controller/method, I got this PDF to generate with this code.

It’s nothing special, but it’s just an example of how you can add a bit more than ‘Hello World’ to the top of a PDF. I’m still working on figuring out all the x/y stuff. Maybe I will post a better tutorial in the future with headers and footers.
Until then… have fun!
