ActiveRecord Caching

Adds "Advanced Caching" to ActiveRecord::Base as described in Adam Hawkins' blog, Fast JSON APIs.

Add this line to your application's Gemfile:

gem 'active_record_caching'

And then execute:

$ bundle

Or install it yourself as:

$ gem install active_record_caching

Index controller actions will support #stale?

class ResourceController < ApplicationController
  responds_to :json

  def index
    # uses the new #cache_key method defined on ActiveRecord::Base to
    # set the etag
    if stale? collection do
      # Use cached JSON from individual hashes to render a collection
      respond_with collection
    end
  end
end
