Resources to learn ActiveResource in Rails 3 - in pragmatic way

Can somebody point me to resources that will hel开发者_JAVA技巧p me understand A to Z of ActiveResource in Rails 3?

I tried looking out for books and articles in vain :(

Pointers to any open-sourced project that I can play with should also be of help.

Your help is much appreciated. Thanks in advance.

Having recently worked with ActiveResource I can empathize with you. I can tell you that there hasn't been much work done on ActiveResource since Rails 2.3. I've heard rumor that there's a rewrite coming after 3.1 (or maybe it's actually been done in 3.1).

I'd suggest the Railscasts at ActiveResource Basics and More On ActiveResource If you have a copy of The Rails 3 Way there is a chapter there. Otherwise, the best resource I was able to find was the code itself.
