Heroku | Cloud Application Platform Rails Routing from the Outside In 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 for: it asks the router to match it to a controller action. 1.2 Generating Paths and URLs from Code You can also generate paths and URLs. and your application contains this code in the controller: and this in the corresponding view: then the router will generate the path /patients/17. 2 Resource Routing: the Rails Default Resource routing allows you to quickly declare all of the common routes for a given resourceful controller. 2.1 Resources on the Web Browsers request pages from Rails by making a request for a URL using a specific HTTP method, such as GET, POST, PATCH, PUT and DELETE. it asks the router to map it to a controller action. 2.2 CRUD, Verbs, and Actions 2.3 Path and URL Helpers 2.5 Singular Resources
Ruby, Ruby on Rails, and _why: The disappearance of one of the world’s most beloved computer programmers Illustration by Charlie Powell. In March 2009, Golan Levin, the director of Carnegie Mellon University’s interdisciplinary STUDIO for Creative Inquiry, invited an enigmatic and famed computer programmer known to the virtual world only as “Why the Lucky Stiff” or “_why”—no, not a typo—to speak at a CMU conference called Art && Code—also not a typo—an event where artsy nerds and nerdy artists gather to talk shop. _why came to Pittsburgh and presented his latest project to a room full of a student programmers and artists. At this symposium, he wore a pair of oversize sunglasses and a tidy sports coat with a red pocket square, a silly riff on a stuffy professor’s outfit. He riffed on his nom d’Internet, Why the Lucky Stiff: “Some people want to call me Mr. Then he introduced his new product, a free interactive application called Hackety Hack, which he had built from scratch to solve a problem he called the “Little Coder’s Predicament” in a 2003 manifesto.

Ruby Kickstart 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. Ruby is an awesome all-purpose language with a multitude of uses (it’s not just for web apps!) Is there really a best way to learn Ruby & Rails?
Ruby in Twenty Minutes What if we want to say “Hello” a lot without getting our fingers all tired? We need to define a method! irb(main):010:0> def hiirb(main):011:1> puts "Hello World!" The code def hi starts the definition of the method. The Brief, Repetitive Lives of a Method Now let’s try running that method a few times: irb(main):013:0> hiHello World! Well, that was easy. What if we want to say hello to one person, and not the whole world? irb(main):015:0> def hi(name)irb(main):016:1> puts "Hello #{name}!" So it works… but let’s take a second to see what’s going on here. Holding Spots in a String What’s the #{name} bit? irb(main):019:0> def hi(name = "World")irb(main):020:1> puts "Hello #{name.capitalize}!" A couple of other tricks to spot here. Evolving Into a Greeter What if we want a real greeter around, one that remembers your name and welcomes you and treats you always with respect. The new keyword here is class. So how do we get this Greeter class set in motion?
Infographic Creation Made Easy with Visual.ly Create Today marks an important milestone for Visual.ly: the release of our tools for automatic infographic creation. Our team has made hundreds of infographics, so we know how hard it can be to find the data, do the necessary research, and make sure you are following the principles of good data visualization, while still coming up with a design that people will want to hang on their wall and spread through the interwebs. That’s why we’ve built data feeds into a number of infographic designs, created for you by our team of expert designers. We are social creatures, so we thought it only natural to start with Twitter and Facebook. Another reason was our launch at the SXSW Festival, a place where many new stories are being told. But this is just the beginning. Once you’ve created an infographic with Visual.ly Create, we hope you’ll share it with the community by posting to your Visual.ly profile or sharing with your friends on social networks.

The First 45 Years Of Star Trek I feel almost childishly uneducated when it comes to Star Trek, and the culture that surrounds this quite amazing series of movies and TV shows. There is no doubt Star Trek has had a huge impact on society, and I think the cast members should feel proud that they have been a part of a world-changing concept that will only grow stronger with time. There are gadgets, technologies and styles all derived from Star Trek, and I am sure no one could disagree with me when I say that Star Trek has had as much of an impact on the world as Star Wars, if not more. It’s once again a question about which side you vote for. It’s with fascination that I begin to read and look through this information packed Star Trek infographic which replays 45 years of pure sci-fi history.
Exploring the Elegance of Sinatra: A Lightweight Alternative to Rails 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. This week I decided to take a look inside of Sinatra to see what I could learn from the way it was written. Today I’ll show you three examples of this: how Sinatra calls your code via throw and catch, how Sinatra uses Test::Unit in a very readable and DRY manner, and how it uses metaprogramming in an elegant way that makes it easier for client code to use. Using throw/catch to control program flow If you’ve ever used or read about Sinatra, you’ll remember that you provide code to handle HTTP requests using a series of blocks and route patterns. 1.get '/hi' do 2. 3.end 2.def route_eval 3. throw :halt, yield 4.end Huh? 2.def invoke 5. ... etc ...
