Boost your Rails Controller params[:fu]

In many ways, in a Rails controller POST action, what gets POST-ed in params are often overlooked. In many straight-forward tutorials, we slap a forms_for @customer in our view, and then the params will come out to be directly consumable by our ActiveRecord model. Unfortunately, many new Rails developers cannot see beyond the usefulness of hashing the posted parameters accordingly. In the next few blog posts, I intend to show you that if you take the time to assemble your params the way Rails likes it, you can dramatically reduce the amount of code you have to write in your controller actions and models, simply because Rails takes care of it for you. The end result is getting it done in less code, fewer tests, less trouble.
