Ruby on Rails Guides Why's (Poignant) Guide to Ruby why’s (poignant) guide to ruby :: 2. Kon’nichi wa, Ruby 1. Opening This Book Pretend that you’ve opened this book (although you probably have opened this book), just to find a huge onion right in the middle crease of the book. So you’re like, “Wow, this book comes with an onion!” Then you ask yourself, “Wait a minute. No. I’ll be straight with you. You really must sob once. 2. So try this first bit of poignancy on for size: One day I was walking down one of those busy roads covered with car dealerships (this was shortly after my wedding was called off) and I found an orphaned dog on the road. We set off to get some Milkbones for Bigelow and, afterwards, head over to my place, where we could sit in recliners and listen to Gorky’s Zygotic Mynci. But Bigelow hadn’t accepted me as his master. Stupid Benedict Arnold of a dog. I wonder where he went with all those balloons. It wasn’t much later that I pulled my own Bigelow. I sat, staring out the window at the world, a life-sized blender mixing graffiti and iron smelts before my eyes. 3. 4.
Ruby in Twenty Minutes Introduction This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. (If you do not have Ruby on your computer install it before you get started.) Interactive Ruby Ruby comes with a program that will show the results of any Ruby statements you feed it. Open up IRB (which stands for Interactive Ruby). If you’re using macOS open up Terminal and type irb, then hit enter. irb(main):001:0> Ok, so it’s open. Type this: "Hello World" irb(main):001:0> "Hello World" => "Hello World" Ruby Obeyed You! What just happened? irb(main):002:0> puts "Hello World" Hello World => nil puts is the basic command to print something out in Ruby. Your Free Calculator is Here Already, we have enough to use IRB as a basic calculator: irb(main):003:0> 3+2 => 5 Three plus two. irb(main):004:0> 3*2 => 6 Next, let’s try three squared: irb(main):005:0> 3**2 => 9 In Ruby ** is the way you say “to the power of”. Ok, wait, what was that last one?
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. About the author Copyright and license 1.1 Introduction
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. 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. Run gem install rails to install Rails. Next, you need to install Rails. Great!
