Sounds like the first one could've used http://trailblazer.to/ http://trailblazer.to/ - so far I'm using the [Reform](https://github.com/apotonick/reform https://github.com/apotonick/reform) gem more because the app I'm currently working on is getting more forms that consists of multiple models (ActiveRecord and API). A shame that the [ActionForm](https://github.com/railsgsoc/actionform https://github.com/railsgsoc/actionform) GSoC project didn't make it to Rails core. I haven't bought the Trailblazer book yet but I probably will somewhere in the next couple of weeks.
