Simple (and incomplete) Facebook Graph API wrapper for public objects. It is incomplete on purpose for a ruby lesson :)

graph_api.rb

require 'rubygems'
require 'open-uri'
require 'json'
require 'ostruct'

def get_graph_object(object_id)
  graph_json = open("https://graph.facebook.com/#{object_id}").read
  data_hash = JSON.parse(graph_json)

  parsed_hash = parse_hash(data_hash)

  parsed_data = OpenStruct.new(parsed_hash)
end

def parse_hash(data_hash)
  data_hash.inject({}) do |new_hash, data_array|
    result_data = data_array[1]
    if result_data.is_a? Array
      result_data = result_data.map {|hash| parse_hash(hash)}
    elsif result_data.is_a? Hash
      result_data = OpenStruct.new(parse_hash(result_data))
    end
    new_hash[data_array[0]] = result_data

    new_hash
  end
end

# GOAL:
result =  get_graph_object("99394368305") #.-> #<OpenStruct name="Facebook Developers", is_published=true, ...
