I finally played a bit with the REST part of Rails. Over the weekend, I made my first RESTful web app. How did it go? I don’t know. I don’t think I’ve yet made the mental switch. There’s a few things that bug me about REST, and I’m not sure I can put it in words yet.
I think there’s “REST” and “Rails REST”. The way Rails does REST seem to be a subset of REST, or at least it puts more constraints on how you should do it.
The one thing that bothers me the most is the respond_to and how you can handle different formats. Yes it is nice to be able to reuse the same action and send back XML or CSV or a basic html representation of the information. But when it comes to the actual UI of your application, the html, the forms, the navigation, I don’t want my user to interact with the application the same way a machine would.
Maybe I should investigate a bit more the RADAR architecture as described by Dave Thomas. The idea is to have the html application be another layer on top of your resources.
