It's a framework for developing servers that adhere to the Restful Objects specification. It's main purpose is to be completely transparent to the developer and let him focus mainly on the Domain Model that implements the business logic, thereby abstracting him from the API & HTTP issues of exposing the Restful resources.

So it's like plain old ruby objects, with HTTP Restful steroids for free!

require 'restful_objects'

class Node
  include RestfulObjects::Object

  property   :label, :string
  property   :visited, :bool
  collection :dendencies, Node
end

class Graph
  include RestfulObjects::Object

  collection :nodes, Nodo
  action :topological_sort, return_value: { list: Nodo }

  def topological_sort
    list = []
    nodex.each { |node| node.visited = false }
    unvisited_nodes = nodes
    while not unvisited_nodes.empty? do
      visit(unvisited_nodes.pop, list)
    end
    list
  end

  private

  def visit(node, list)
    if !node.visited
      node.dependencies.each { |dependent_node| visit(dependent_node, list) }
      node.visited = true
      list << node
    end
  end
end

If you have a Ruby environment (> 1.9.3) with RubyGems installed, simply run:

gem install restful_objects

or add,

gem 'restful_objects'

to your's project Gemfile and 'bundle install' it.

If not, consider using Vagrant to setup a VM with all the dependencies and the latest version of the framework following the instructions here:

The source quality is at alpha state, and it was created mostly as a proof of concept. Still is has plenty of specs and a big percentage of the specification implemented, the grey areas are mostly related to errors and validations. It has been developed with MRI and hasn't been tested on other Ruby implementations.

• Ruby 1.9.3 or higher
• Sinatra
• RSpec
• json_expressions for json testing.
