Best way to learn Ruby & Rails - @AstonJ's Blog
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. If you’re only interested in learning Ruby, just skip over the Rails bits. Is there really a best way to learn Ruby & Rails?

The Asset Pipeline
1 What is the Asset Pipeline? The asset pipeline provides a framework to concatenate and minify or compress JavaScript and CSS assets. It also adds the ability to write these assets in other languages and pre-processors such as CoffeeScript, Sass and ERB. The asset pipeline is technically no longer a core feature of Rails 4, it has been extracted out of the framework into the sprockets-rails gem. The asset pipeline is enabled by default. You can disable the asset pipeline while creating a new application by passing the --skip-sprockets option. Rails 4 automatically adds the sass-rails, coffee-rails and uglifier gems to your Gemfile, which are used by Sprockets for asset compression: Using the --skip-sprockets option will prevent Rails 4 from adding sass-rails and uglifier to Gemfile, so if you later want to enable the asset pipeline you will have to add those gems to your Gemfile. 1.1 Main Features The second feature of the asset pipeline is asset minification or compression.

Ruby on Rails Tutorial: Learn Rails by Example book and screencasts by Michael Hartl
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. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby Acknowledgments The Ruby on Rails Tutorial owes a lot to my previous Rails book, RailsSpace, and hence to my coauthor Aurelius Prochazka. I’d like to acknowledge a long list of Rubyists who have taught and inspired me over the years: David Heinemeier Hansson, Yehuda Katz, Carl Lerche, Jeremy Kemper, Xavier Noria, Ryan Bates, Geoffrey Grosenbach, Peter Cooper, Matt Aimonetti, Gregg Pollack, Wayne E.

The Best Way to Learn Rails
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. So that begs the question: what's the best way to learn Rails? This article details a full lesson plan that will get you up and running in no time! You might think learning Ruby is the most important step, and this is probably the part where everyone stops learning and just sticks with their current framework. Work through the Try Ruby exercises. The most recommended tool for dipping into Ruby's syntax is the Try Ruby website. Once you’ve worked through these exercises a couple of times, you'll have a solid base. Great! Railscasts: A must!
