Not sure how to frame this question (I'm still wrapping my head around Rails). Let's try this: Say I wanted to implement the user side of Ryan Bates' excellent railscast on nested models. (He shows how to implement a survey where you can add and remove questions and answers dynamically). I want the user's side of this: to be able to a...

There are a number of resources online that host Rails and Ruby documentation in various forms and styles. A number of them are good, but none of them document the modules and classes with the methods available from the numerous extensions provided by ActiveSupport and others. For example, with the Standard ruby Hash class, the core ru...

Moving forwa...
