Fat Model, Skinny Controller Arguably one of the most important ways to write clear and concise code in Ruby on Rails, the motto “Fat Model, Skinny Controller” refers to how the M and C parts of MVC ideally work together. Namely, any non-response-related logic should go in the model, ideally in a nice, testable method. Let’s look at a simple example. You can change it to this: Then, you can move the logic to your post model, where it might look like this: Reusable Scopes and Relations And in Rails 2: Virtual Attributes

Learn It often feels like "best practices" have a shelf-life of a few months before being replaced by better ideas. Between Rails’ constant changes and a never-ending stream of new gems and philosophies, it’s a real challenge to keep up with the state of the art. Stay on top of it by reading the source of the Learn app itself, watching the thoughtbot team contribute to it, reading our books (which also come with high quality source code), and watching screencasts on vim, development tools, and more.

SchmidtHappens | Evaluating Different Ruby and Rails Versions with RVM If you've ever had to test an application that you are building with different versions of Ruby or Rails then you know how frustrating it can be. RVM aims to erase that frustration by making it incredibly easy to install multiple versions on the same development machine. The first thing that you will need to do is install RVM. To do this open a terminal and enter in the following command (please note, you will need to make sure you have git installed): bash < <(curl -s Once the install finishes you will be instructed on how you can update your .bash_profile file with a load path to the rvm executable. Great, now that we've gotten that out of the way it's super simple to install new Ruby versions. To use an installed Ruby use the following (substitute the version you want): Wondering which Ruby versions are available for download? Want to know which you already have installed? What About Rails? rvm gemset create rails31 Something missing?
HTML5 Makes a Great Color Picker HTML5 is changing more than just websites — it’s changing the capabilities of browsers, as well. For example, a very clever use of the HTML5 canvas tag allows developer Heather Arthur’s Rainbow color scheme add-on for Firefox to extract a color palette from any webpage. Because browser add-ons — those in Firefox and Chrome anyway — can be built using HTML, they too can take advantage of HTML5′s new tools. In Arthur’s case, that means using the HTML5 <canvas> element to load the entire web page and then use the getImageData function to extract colors. Now it’s true there are already some add-ons (and desktop software) that can do this, but the shortcoming of most such add-ons is that they simply parse a page’s DOM and extract CSS styles to build a color palette. Arthur’s method of putting the page in a canvas tag and then parsing that means that all the colors are extract since the entire page effectively becomes a single, parsable image. See Also:
My Experiences with Ruby off Rails I was recently pointed to Ben Singelman’s post on Why Nobody Should Use Rails For Anything, Ever. We seem to never get enough of arguing about application frameworks: I’m not going to do that. What irks me is when Ruby get thrown out with the Rails bathwater. As one commenter on Singleman’s post demonstrates: “Interesting perspective. (This despite the second sentence of the post stating “Independent of ruby, I see Rails as the emperor with no clothes on.”) I see posts like this a lot. Don’t pick on Ruby just because you don’t like Rails Despite making use of Ruby since 2004, I’ve never personally written a Rails app for a customer. I was an early advocate for Rails, discovering it in 2005 and attending RailsConf in 2007. On my current project, we sort of tried to use Rails but ended up using just the asset pipeline to make an Ember app backed by a Grape API. Language and framework wars aside, there are many other ways to make Ruby useful
