If I had to choose the single most not-really-well-understood, mystified, unsuccessfully demystified, explained and still not-really-grasped topic in the Rails world (and beyond), my vote would definitely go to REST. It seems to me that there are two types of people in the world: those who don’t get REST (and they think it’s a basic postulate to rocket science explained through quantum theory) and those who get it, and don’t understand the former group (unless they are coming from there, that is).
I have been playing around with RESTful Rails recently. Below is my collection or Rails REST howtos, tutorials and other resources I have found so far and which were adequate for my transition from the first group to the second .
You should definitely begin with REST 101 – then check out the other stuff as well!
- REST 101 by Softies on Rails
- RESTful Rails Development
- A great PeepCode screencast: RESTful Rails
- A nice REST cheatsheet
- A presentation on REST and ActiveResource
Please leave a comment if you know some more (just for completeness’ sake – I think the above resources should be enough to grasp RESTful Rails both theoretically and practically.
