This is more tricky than it should be because url_for, asset_path, etc. all rely on different mechanisms.

Anyway, you can use the attached trait like this:

class ExampleController < ApplicationController
  does 'host_enforcement', :for => 'some_action'
end

Short explanation:

• asset_host is used for links to stylesheets and javascripts
• asset_host belongs to ActionController::Base -- changes are persistent and will not be reset after a request
• rewrite_options is used by the ..._path methods in the views

RubySpec is a project to write a complete, executable specification for the Ruby programming language.

Ancestry is a gem/plugin that allows the records of a Ruby on Rails ActiveRecord model to be organised as a tree structure (or hierarchy). It uses a single, intuitively formatted database column, using a variation on the materialised path pattern. It exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants) and all of them can be fetched in a single sql query. Additional features are STI support, named_scopes, depth caching, depth constraints, easy migration from older plugins/gems, integrit...

The Rails router has been written and rewritten at least four times2, including a recent rewrite for the upcoming Rails 3. The syntax is now more concise.<br />

But never mind making it shorter! It’s time for a final rewrite: Let’s get rid of it altogether!

The jQuery project is really excited to announce the work that we’ve been doing to bring jQuery to mobile devices. Not only is the core jQuery library being improved to work across all of the major mobile platforms, but we’re also working to release a complete, unified, mobile UI framework.

You’re a business, calling a business, about conducting business. Don’t be surprised when money comes up.

The first thing I need to say, right off the bat: Chinese users will not buy your software. Period. That does not mean that there is no money to be made, it simply means that they will not pay for your software license.

Computer science is about tradeoffs and hard choices. Optimizing the code or design or architecture one way means taking hits another way.

Johnson wraps JavaScript in a loving Ruby embrace. It embeds the Mozilla SpiderMonkey JavaScript runtime as a C extension.

The Holy Grail of testing for front-end development; execute browser-less, console-based, javascript + DOM code right from within your Rails test suite.

While injecting the dependency appeared to make the classes more tightly coupled, it simply revealed the coupling that already existed. A was already tightly coupled to B and B to C. When we tried to inject the dependency, we made that coupling more explicit and easier to remove.

Programming is a deceptively damaging field to be in, partly because it doesn't seem like you're doing much, and also because of the attitude many programmers have toward their body. You should care about keeping yourself healthy because, when your body is in good shape, that removes "friction" from your mental capacity so that it can focus on important things rather than annoying little problems with your physical wellness.

...you can apply every available anti-pattern and still come out the other end with a workable system, simply because the hardware can move faster than your bad decision-making.

We didn’t want to leave front-end developers in the dark when their Javascript throws errors, so we’ve added a Hoptoad notifier for Javascript!

The problem isn't that Git is to hard, it's that smart developers are impatient and have exactly zero tolerance for unexpected behavior in their tools. While Git is the trendy thing right now, perhaps some day you will come across a grizzled developer who is using SVN, and when you ask him why, his answer won't make sense, because it's a Zen thing.

Gerrit is a web based code review system, facilitating online code reviews for projects using the Git version control system.
