Rack::RESTfulController

I had a crazy idea the other day. Write a class that looks like a "RESTful" Rails controller. Pass it to Rack. And with the help of a little middleware action... voilà!

Only today, when I fleshed it out completely did I think, "This could be useful for writing a quick prototype then moving it to Rails when it's ready." It's probably useful for that too.

This is the fruition of those things.

Install

gem install rack-restful-controller -s http://gemcutter.org

Usage

config.ru

require 'rack/restful-controller'

class Foo
  def index
    "this is the index" # return a string, it becomes [200, {...}, ["this is the index"]]
  end

  def show
  end

  def create
    [302, {'Location' => '/42', ...}, ["body"]] # return an array, and it's just passed along to Rack
  end

  def edit
  end

  def update
  end

  def destroy
  end

  def foo
  end

  def bar
  end
end

use Rack::RESTfulController, :collection => {:foo => :get}, :member => {:bar => :get}
run Rack::RESTfulController.as(Foo)

Caveats

Rack::RESTfulController#call isn't really that robust, but it works. Welcome to suggestions.
I don't really like the name of Rack::RESTfulController.as, but it was the best I could think of at the time.

TODO

TEST
Write a few helper methods; redirect_to, *_path, *_url
