While I agree with much of what Peter said, I have had extensive experience with generating .pdf files, including PrinceXML. The problems which I experienced with PrinceXML were (a) it requires an "external" step in that you have to generate the .pdf from Prince, based on a file which you created from your ROR application; and (b) you have to manually go into the xml file and "escape" things like "&" signs. Also, Prince requires that you generate a specific .css file (no big deal, but another step). After playing with various other .pdf generation techniques, I landed on the combination of the Prawn gem and the Prawnto plugin, which allow a seamless integration of your ROR application and .pdf output. As far as the issue of "headers" at the start of each page, what I do is to simply start each individual item with a NewPage followed by a Header partial. Good luck with your EOY project, and ROR is definitely the way to go. Sandy -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
