This gist is outdated

Homebrew people have since included this in a recipe.

Railties 3.1 Beta 1

• The -j option of the application generator accepts an arbitrary string. If passed "foo", the gem "foo-rails" is added to the Gemfile, and the application JavaScript manifest requires "foo" and "foo_ujs". As of this writing "prototype-rails" and "jquery-rails" exist and provide those files via the asset pipeline. Default is "jquery". [fxn]

• jQuery is no longer vendored, it is provided from now on by the jquery-rails gem. [fxn]

• Prototype and Scriptaculous are no longer vendored, they are provided from now on by the prototype-rails gem. [fxn]

• The scaffold controller will now produce SCSS file if Sass is available [Prem Sichanugrist]

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

Routes

小心地使用 Match（Rails 3 已实现）

Rails 3 提供了 match 方法供我们自定义 routes，然而我们要小心使用它以避免“跨站脚本攻击”（XSS Attack）。比如像这样的 routes：

注：（r3 代表 Rails 3，r4 代表 Rails 4）

# routes.rb
