Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

Started GET "/" for 127.0.0.1 at Mon Sep 06 01:07:11 -0400 2010

Sprockets Railtie Setup

This file at actionpack/lib/sprockets/railtie.rb defines the Sprockets::Railtie, defining another Railtie for Rails. This Railtie is responsible for detecting if the application at-hand is using CoffeeScript, and if so will set config.app_generators.javascript_engine on the application to be :coffee.

Next, this defines an initializer called sprockets.set_configs which sets up ActionController::Base to either use or not use sprockets depending on the configuration option config.assets.enabled.

Finally, this file defines an after_initialize hook for the application which is the real meat of this Railtie. If assets are disabled (with the config.assets.enabled config option set to false) then this after_initialize hook will do nothing.

If assets are enabled then, this initializer first makes a call to an asset_environment protected method near the bottom of this file which requires the sprockets gem, creates a new Sprockets::Environment object, and then co
