Learn Ruby on Rails: the Ultimate Beginner's Tutorial [Server Side Essentials]

Rolling with Ruby on Rails Maybe you've heard about Ruby on Rails, the super productive new way to develop web applications, and you'd like to give it a try, but you don't know anything about Ruby or Rails. This article steps through the development of a web application using Rails. It won't teach you how to program in Ruby, but if you already know another object-oriented programming language, you should have no problem following along (and at the end you can find links on learning Ruby). Let's answer a couple of burning questions before rolling up our sleeves to build a web application! Ruby is a pure object-oriented programming language with a super clean syntax that makes programming elegant and fun. Ruby successfully combines Smalltalk's conceptual elegance, Python's ease of use and learning, and Perl's pragmatism. Rails is an open source Ruby framework for developing database-backed web applications. Part of the answer is in the Ruby programming language. I'm not asking you to accept this on blind faith.

At the Forge - Getting Started with Ruby About ten years ago, back when I was working in New York, friends of mine showed me something that knocked my socks off—a program that actually ran inside of the Web browser, without any need for pressing submit. It was sleek, fun to use and seemed like a major paradigm shift. We all were excited about what this new “Java” language and its applets would mean for Web development. Although we didn't quite know where or how it would end, we talked about nothing else for some time. In the decade since then, many different technologies have been hyped as “the next best thing” or “the tool you need to make better Web sites”. Indeed, we constantly are bombarded with claims of newer, better, faster and cheaper ways to develop software. You can imagine my surprise, then, when I began to see another “best new method” coming over the horizon—but this one was touted by people I respect, who normally don't give in to hype so quickly. Here is a simple “Hello, world” program in Ruby: #! #! #! #!

A Wealth Of Ruby Loops And Iterators I remember when I first started looking at Ruby, I’d be browsing some code and see yet another way of looping/iterating over stuff. Whenever that would happen I would think, “…Ruby sure has a lot of different ways to iterate over things”, but I also remember wishing that someone would just put all the different ways to loop and iterate over stuff together so that you don’t have to discover them in a piecemeal fashion. Most resources I’ve seen tend to gloss over this a little bit by introducing the while loop and the each iterator and quickly moving on to more interesting things, expecting you to discover the rest on your own (nothing wrong with that by the way). As you may have guessed from my recent posts on Ruby method arguments (and more advanced method arguments), the Ruby case statement and others, I am kind-of discovering Ruby in my own way and looking more closely at things that I find of interest. Ways To Loop Over Stuff In Ruby Unconditional Looping With Loop The While Loop

Top 12 Ruby on Rails Tutorials A former student asked me a few days ago how I learned Ruby on Rails. The answer was that I simply read alot of great tutorials.

Ruby: How to bring back the joy of programming Ruby is a nice scripting language similar to Perl but cleaner and fully object-orientated. Find here a pointer to the main site about Ruby. Ruby Central also has a lots of data about Ruby. You can find here a link to an online copy of the book « Programming Ruby », by Andrew Hunt & Dave Thomas. Current development version is 1.9.2-p180. Alongside with Ruby, I’ve discovered the joys of a very neat and nicely designed web application framework called Ruby on Rails . Some of my Ruby code here , oldish ciphers implemented in Ruby following the Test-Driven Development principle. A few years ago, a non-profit association ( in French) was established in France to help further spread Ruby usage and love. Some pictures taken at Solutions Linux 2009 here on Flickr!

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. 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. Roadmap for Learning Rails Ruby Ruby is the most important technology to know when learning Rails. Tools

ActionView::Helpers::TextHelper The TextHelper module provides a set of methods for filtering, formatting and transforming strings, which can reduce the amount of inline Ruby code in your views. These helper methods extend Action View making them callable within your template files. Sanitization Most text helpers by default sanitize the given content, but do not escape it. This means HTML tags will appear in the page but all malicious code will be removed. Let's look at some examples using the simple_format method: simple_format('<a href=" # => "<p><a href=\" simple_format('<a href="javascript:alert(\'no! If you want to escape all content, you should invoke the h method before calling the text helper. Methods excerpt highlight pluralize reset_cycle truncate word_wrap Included Modules Instance Public methods The preferred method of outputting text in your views is to use the <%= “text” %> eRuby syntax. def concat(string) output_buffer << stringend Options

Ruby on Rails Guides 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!

ruby on rails - How can I display every 4th product with different markup Learn to Program, by Chris Pine A Place to Start for the Future Programmer I guess this all began back in 2002. I was thinking about teaching programming, and what a great language Ruby would be for learning how to program. I mean, we were all excited about Ruby because it was powerful, elegant, and really just fun, but it seemed to me that it would also be a great way to get into programming in the first place. Unfortunately, there wasn't much Ruby documentation geared for newbies at the time. Some of us in the community were talking about what such a "Ruby for the Nuby" tutorial would need, and more generally, how to teach programming at all. And it wasn't very good. What saved me was that I made it really easy for people to contact me, and I always tried to help people when they got stuck. A couple of years later, it was getting pretty good. :-) So good, in fact, that I was ready to pronounce it finished, and move on to something else.
