  1. Javascript Best Practices

    One thing I've found really lacking in most Rails books is how to properly do JS. I think you should just gloss over the JS helpers and focus how to properly do JS inside a rails app. Fundamental things like using JSON for separation between controllers and front end. What to use wants.js for. And how doing your JS horribly can really muck up your app.

    JS Testing too. Integrating with cucumber/capybara. Not sure if this outside the scope or not :)

            I think this is an absolutely essential part of any Rails book. You have to be monitoring the exceptions that will happen, even if you are doing testing.

            Then you also have to be monitoring for when the server / something else blows up.

            Great suggestion!

            • Stack agnosticism: how and when to swap in stack substitutes?

              One of the central ideas to the Rails 3 version is that each part of the standard Rails stack is replaceable. Use practical examples of swapping in substitutes and, even, how to write your own substitutes and properly hook in.

                  Now that the logic that governs ActionView etc. has been re-written to be completely pluggable. I'd like someone to explore the depths of just how flexible and dynamic it is.

                    An obvious topic, but I think an important one for a Rails 3 book.

                      When changed-from-Rails-2 things are mentioned I was thinking of having like a footnote, or a reference number next to these things and an appendix at the end listing the changes.

                                    Please describe which Rails components are executing throughout a page's lifecycle. I think it would be most helpful to start with the "web server receives request and passes it off to..." and end with "the bits are sent to the user." At the very least, it would be very helpful for me if you provided an overview/graphic of the lifecycle.
