I’ve been using Prawn for the past 3 years to generate PDFs in my Rails projects. It has a little bit of a learning curve up front but gives you much more power than just rendering out your web views as PDFs.
That said one problem I ran across was how to design/implement repeating footer. After a lot of digging I came up with the solution below:
If you are curious how you actually go about using this PDF in your project, you can refer to Ryan Bates’ always awesome Railscasts, episode #153.
On a side note, Ryan took the summer off and was originally going to come back in September, but then later announced he wasn’t ready to come back yet. While I can definitely understand burnout and needing some time away, I hope to see him back in action soon.
