0.??Getting Started When you program a computer, you have to "speak" in a language your computer understands: a programming language. There are lots and lots of different languages out there, and many of them are excellent. In this tutorial I chose to use my favorite programming language, . Aside from being my favorite, Ruby is also the easiest programming language I have seen (and I've seen quite a few). In fact, that's the real reason I'm writing this tutorial: I didn't decide to write a tutorial, and then choose Ruby because it's my favorite; instead, I found Ruby to be so easy that I decided there really ought to be a good beginner's tutorial which uses it. It's Ruby's simplicity which prompted this tutorial, not the fact that it's my favorite. When you write something in a human language, what is written is called text. code . If you come across something you don't understand, or you have a question which wasn't answered, write it down and keep reading! Windows Installation Global Properties
Ruby on Rails Guides: Débuter avec Rails Ce guide utilise Rails 3.0. Une partie du code montré ici ne fonctionne pas avec les versions précédentes de Rails. 1 Ce que ce guide suppose Ce guide est conçu pour les débutants qui veulent s’initier à la création d’une application Rails. Il ne suppose aucune expérience avec Rails. Cependant, pour vraiment en profiter, voici les pré-requis logiciels indispensables : le langage Ruby, au minimum la version 1.8.7 Note that Ruby 1.8.7 p248 and p249 have marshaling bugs that crash Rails 3.0. Rails est un framework pour le langage Ruby. 2 Qu’est-ce que Rails ? Rails est un framework pour le développement d’applications web écrit avec le langage Ruby. Rails est “opiniâtre” (opinionated software). La philosophie de Rails comprend ces principes fondamentaux : DRY – “Ne vous répétez Pas” (Don’t Repeat Yourself) – suggère qu’écrire et ré-écrire le même code à plusieurs reprises est une mauvaise chose. 2.1 L’architecture MVC 2.1.2 Vues Les vues sont l’interface utilisateur de votre application.
Learn Ruby with the EdgeCase Ruby Koans Roadmap for Learning Rails | techiferous Accelerating Your Learning If you have no prior development experience, one of the worst things you can do when learning Rails is to just dive in. Some of the concepts build on each other, so jumping in would be like signing up for a calculus class before you’ve learned algebra. Sure, you could muddle through it, but most of your time would be spent trying to figure out why things aren’t working. Another difficulty for a beginner is figuring out what to learn. SQL, XHTML, CSS, XSS, RDF, RDBMS–what should you drink from the fire hose of acronyms? Another mistake is spending too much time mastering a concept when you only need a basic understanding. Therefore, to accelerate your learning, learn the right things in the right order at the right depth. The following roadmap will help you do exactly that. But First Some Ground Rules… It takes a significant investment of time to learn Rails. Otherwise, you will waste your time learning Rails when all you really needed was WordPress. Ruby Key Concepts
Ruby Object Oriented Programming From Techotopia Purchase and download the PDF and ePub versions of this Ruby eBook for only $8.99 Ruby is an object oriented environment and, as such, provides extensive support for developing object-oriented applications. The area of object oriented programming is, however, large. [edit] What is an Object? An object is a self-contained piece of functionality that can be easily used, and re-used as the building blocks for a software application. Objects consist of data variables and functions (called methods) that can be accessed and called on the object to perform tasks. Just about everything in Ruby, from numbers and strings to arrays is an object. [edit] What is a Class? Much as a blueprint or architect's drawing defines what an item or a building will look like once it has been constructed, a class defines what an object will look like when it is created. New classes can be created based on existing classes, a concept known as inheritance. [edit] Defining a Ruby Class
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! 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. If you want to learn Rails, you’ll of course need to install it on your machine. Next, you need to install Rails. Great!
The Rubyist Historian: The Series | Jason Heppler The Rubyist Historian: The Series Coming off my recent post on How I Learned Code, I’ve decided to write a series of blog posts that will introduce historians to the basics of Ruby that I will eventually publish as a free ebook. My hope is to write an accessible introduction to Ruby and demonstrate not only how to write small programs but also think about ways programming can help scholars in their everyday tasks. Although I’m aiming this at historians, my hope is that anyone interested in humanist computing (or Ruby in general) will find this useful. You can find copies of code examples in the Rubyist Historian Github repository. Contents 1: Getting Started 2: Methods and Classes 3: Loops and Control Structures 4: Arrays and Hashes 5: Working with Advanced Data 6: Randomness 7: Our First Program Acknowledgements The structure, examples, and topics that comprise this blog series are directly inspired by and drawn from Prof.

How I Learned Enough Ruby On Rails In 12 Weeks To Launch Freelancify • JamesFend.com (Update February 26, 2013: I have since this post sold Freelancify.com to a new owner) Before I begin, I’d like to recognize Josh Crews ( for convincing me to learn Ruby on Rails; without him and his hours of volunteered mentership and help, I wouldn’t be writing this today. Thank you. I’d also like to address Please do not email me asking me to program your app for equity. On January 23rd, I launched my dream idea, Freelancify.com. And exactly 12 weeks ago, I made the best decision I’ve made in a really, really long time. A correction I’d like to address: Previously, I stated in a post that I learned Rails in 8 weeks; doing an exact recount to launch date, it was more so 12 weeks. What Skills Did I Have Prior To Learning Rails? Why I Decided To Learn It? Sat down that night, and just thought for hours. I decided. My Next 3 Months – Mission: Get an MVP up, had to be enough to work but also not crappy enough to leave a terrible first impression. That’s it guys.

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). 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 Michael Hartl is the author of the Ruby on Rails Tutorial, the leading introduction to web development with Ruby on Rails.
