title: Generate pdf from Rails 3 - what tool to choose?
body: <p>I need to be able to render some views as PDFs from a <strong>Rails 3</strong> project. I've never before used PDF generation techniques with ruby/rails, so I researched a few popular approaches such as <em>Prawn</em> and <em>PDF::Writer</em>, but all the examples and articles I found so far seem outdated and only applicable for rails 2.x. I haven't yet seen a working Rails3 example; tried myself installing prawn and the prawnto gems and reproducing the example described in <a href="http://railscasts.com/episodes/153-pdfs-with-prawn" rel="noreferrer">this Railscasts episode</a>, but I'm getting error of prawnto method not being recognized. I'm uncertain of whether this was an implementation error or just a sign of incompatibility, but seeing other people share on the web that <em>prawn</em> is no longer working for them in Rails3 I didn't bother tracing the code further.</p>
  
  <p>Has anyone found a working reliable solution for pdf generation in Rails3? Could you possibly share it or point me to external resources and documentation?
  Big thanks!</p>
