What are some Rails gems/tutorials/screencasts for creating a PDF file from a form?

The short answer is - Gems. The best way to use Gems is in combination with Bundler (http.//gembundler.com) which makes gem installation, updates and deployment a walk in the park. As for modifications of Gem code, much like plugins, the best way is to override functionality using Mixins while avoiding modifications of the original plugin/gem code. You can read more about Mixins here. http.//juixe.com/techknow/index.php/2006/06/15/mixins-in-ruby

Create PDF: All You Need to Know

Juixe.com/techknow/index.php//mixins-in-ruby-on-rails-in-part-2/ Dry runs are a great way to test your plugin/gem code. One great dry run is the one above but by using dry runs your users can make changes to your plugin/gem code without having to update your code. You could even run dry runs on a test run to save resources and make the server easier to debug but don't do this on a live site because this might break your site. The best thing is to keep a separate test environment. The other option is to run continuous integration for a number of test sites. The good thing is that you can set up Jekyll build packs to do this for you using the same instructions in the first part about using mixing, but it's time-consuming and not always a great solution. You can either run Jekyll builds locally or on the production server so that you can review changes.
