RESTFUL rails

RESTful Rails have been a a much debated part of the Rails core, since the original restful_rails plugin was merged in to core just over a year ago. But with the improvements that have been made in Rails 2.0, they are here to stay, so it is important to understand what they are, how they work and when to (and when NOT to) use them. This is actually a pretty big topic, and I think it is worth while giving you some background first, so I’ll split the post in twain - Part I is theoretical, Part II is practical. So get your network protocol hats on, and get ready to learn about the inner workings of the language of the web.

REST vs. CRUD

Where would the web be with out acronyms? REST stands for REpresentational State Transfer and describes resources (in our case URLs) on which we can perform actions. CRUD, which stands for Create, Read, Update, Delete, are the actions that we perform. Although, in Rails, REST and CRUD are bestest buddies, the two can work fine on their own. In fact, every time you have written a backend system that allows you to add, edit and delete items from the database, and a frontend that allows you to view those items, you have been working with CRUD.
