Now that we've got persistence working, let's add a rudimentary RESTful API to our blog. Really RESTful APIs make heavy use of hyperlinking in the resource representations they serve. For instance, a JSON representation of a blog post might look something like this: Example JSON representation of a blog post
The goto statement is one of the most infamous and troublesome features of old, archaic languages like Fortran. It allowed programmers to quickly create spaghetti code that was confusing and impossible to understand. Thankfully when structured programming came into use in the late 1960s and 1970s with Algol, Pascal and later C, goto was no longer necessary. This is all ancient history: why am I bringing it up? Well, I just discovered this week that Ruby, one of the most beautiful and expressive languages in use today, includes support for the goto statement!
We all know Sinatra as a lightweight alternative to Rails. I find using it is a real pleasure. Sinatra’s helper methods, template support and routing provide just enough to get a simple web site running quickly, but then immediately get out of your way. Years after it was introduced Sinatra remains one of the most popular Ruby web frameworks out there.
March 28, 2012 Modern web development involves a lot of moving parts and a lot of different technologies, and it can be hard to get them all just right. In the heat of development, it’s particularly easy to neglect the presentation layer until it grows to become an unmanageable mess. But you can fix that Broken Window with The Rails View, now in print and shipping from pragprog.com/book/warv .
Michael Hartl Contents Foreword My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP (Google me to read about the drama). This book by Michael Hartl came so highly recommended that I had to try it, and the Ruby on Rails Tutorial is what I used to switch back to Rails again. Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it.
1 The Purpose of the Rails Router The Rails router recognizes URLs and dispatches them to a controller’s action. It can also generate paths and URLs, avoiding the need to hardcode strings in your views. 1.1 Connecting URLs to Code When your Rails application receives an incoming request
That’s no typo, I really did mean Ruby and Rails – but before you run off (those looking to learn only Rails) read on… I started off wanting to learn just Rails too, but I quickly realised two things: Rails will only get you so far – to be anything close to a Rails ninja, you need to learn Ruby (Rails is Ruby underneath it all). While Rails goes out of its way to simplify a lot, once you begin to do more complex stuff you’re going to need to know Ruby – and because Ruby is so easy to pick up anyway it makes sense to learn it from the outset. It will not only save you time in the long run, but will also help you learn Rails as well, because you’ll have a better understanding of what’s going on. Even if you came for Rails, most likely you will stay for Ruby – like so many of us! The more you’re exposed to Ruby the more you’ll want to learn it.

I come from a PHP background, but these days, I’m a full-time Rails developer. The difficulty for most people who make the switch lies in the learning curve that’s involved. Once you’ve become proficient in a language or framework, switching to a new one feels like an unnecessary (and time-consuming) challenge. However, learning Ruby and Rails is actually pretty easy! It’s an incredibly powerful framework, and has a huge community pushing it along.

Rails and Ruby have changed dramatically over the years. For those of us that have been building software on Ruby and Rails for some time, our development stack is likely due for an upgrade. Recently two things led me to review how I build Rails apps. First, I have a new project I intend to build with Rails 3.1. The other event was the release of rbenv as an alternative to RVM .
