hash_it.rb

class Hashit
  def initialize(hash)
    hash.each do |k,v|
      self.instance_variable_set("@#{k}", v.is_a?(Hash) ? Hashit.new(v) : v)
      self.class.send(:define_method, k, proc{self.instance_variable_get("@#{k}")})
      self.class.send(:define_method, "#{k}=", proc{|v| self.instance_variable_set("@#{k}", v)})

This service class helps you to convert a Hash into an object so that you can access all the values like object.key_name instead of hash[:key_name]

Ruby also has inbuilt support for this kind of requirement. OpenStruct is a Ruby data structure made specifically for these kinds of situations. It employs a hash internally to save attribute values. More here.
