Adding Tabs to Your Rails App Just Got a Whole Lot Easier with Tabulous 2

The tabulous gem has continued to grow in popularity ever since I released it in 2011. Since so many people have found it useful, I decided to give it some love. Tabulous 2 is a complete rewrite, featuring a simpler syntax and new behavior. Tabulous is designed to be perfect for quick prototyping, robust enough [...]

So What, Exactly, Is the Purpose of a Rails Controller?

Have you ever hesitated when trying to refactor a controller for simplicity? Sure, you know how to write a controller so that it “works”. You even know how to organize your controllers in a resource-oriented, RESTful way. But when it comes to understanding the purpose of controllers, they’ve always seemed a bit fuzzy. And they’ve [...]

From Ruby to JavaScript

Last Tuesday I spoke at the Boston Ruby Group about strengthening your JavaScript skills. I’ve put the slides online. Enjoy!

Sanely Updating Your Gems

If you followed my advice in the previous post, your Gemfile would look something like this:

source :rubygems
 
gem 'rails', '3.0.3'
gem 'devise', '1.1.5'
gem 'redgreen', '1.2.2'
gem 'capybara', '0.4.0'

There’s nothing wrong with this except that if you wanted to keep your gems up to date frequently it would be tedious to manually change all of these versions. Fortunately, we don’t always have to be this exact with the version numbers.

The No-Nonsense Guide to Managing Gem Versions

If the Ruby code you write never leaves your computer, then this article is not for you. But if you find yourself sharing Ruby code with others, or deploying your Ruby code to a web server, then you have a problem. And that problem is gem versions. Sooner or later, the version of a gem on your computer will not match the version of that gem on your production web server, and your cute little disruptive social media web app will fail in a steaming pile of 500 errors.

Tutorial for Adding Tabs to Rails Using Tabulous

This tutorial shows you how to make a simple Rails application from scratch that has both tabs and subtabs.

Introducing Tabulous: Tabs in Rails

If you’re like me, most of the Rails applications you’ve written use tabbed navigation. And if you’re like me, you find that writing the code to handle tabs becomes increasingly more boring with each new application. So I wrote tabulous. Tabulous aims to solve this problem once and for all with a quick and easy way to set up and manage your tabs.

Roadmap for Learning Rails

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.

Rack::Plastic Helps You Write Rack Middleware

Back in November I participated in the CodeRack Rack middleware contest. Besides submitting entries that were stupid and downright dangerous I actually managed to create some middleware of value.

Using Capybara in Rails 3

Capybara makes it easier to write integration tests. Its syntax is very similar to Webrat’s. The main difference between Capybara and Webrat is that Capybara has more architectural flexibility. It works with a variety of JavaScript-enabled browser simulators and–because it’s based on Rack–it works with any Rack-compatible web application or framework. Another advantage is that Capybara is compatible with Rails 3, but Webrat isn’t. Because Capybara is basically a more flexible Webrat, Capybara and Webrat are likely to merge.
