Replacing Sprocketizer with Sprockets 2.0

routes.rb

Something::Application.routes.draw do
  # ...

  mount SprocketizerReplacement.app => 'sprockets'
end  

sprockets_replacement.rb

module SprocketizerReplacement
  extend self

  def app
    Sprockets::Environment.new(Rails.root.to_s) do |env|
      env.logger  = Rails.logger
      env.version = Rails.env + '-1.0'
      env.cache   = Rails.cache

      env.append_path 'app/javascripts'
    end
  end
end

Shouldn't you always assign Rails.cache? In development, Rails.cache is a simple in-memory cache that is cleared between all requests AFAIK.

Good point!
