convert hash to object

Question

I am trying to convert hash and nested hashes to objects.

so far first hash object is converted successfully by this code:

class Hashit
  def initialize(         


        

Answer 1

If I understand the question correctly, this should do it:

class Hashit
  def initialize(hash)
    convert_to_obj(hash)
  end

  private

  def convert_to_obj(h)
    h.each do |k,v|
      self.class.send(:attr_accessor, k)
      instance_variable_set("@#{k}", v) 
      convert_to_obj(v) if v.is_a? Hash
    end
  end
end

h = Hashit.new( { a: '123r',
      b: { c: 'sdvs', d: { e: { f: 'cat' }, g: {h: 'dog'} } } })
  #=> #"sdvs", :d=>{:e=>{:f=>"cat"}, :g=>{:h=>"dog"}}},
  #       @c="sdvs", @d={:e=>{:f=>"cat"}, :g=>{:h=>"dog"}},
  #       @e={:f=>"cat"}, @f="cat", @g={:h=>"dog"}, @h="dog">
h.instance_variables
  #=> [:@a, :@b, :@c, :@d, :@e, :@f, :@g, :@h]
Hashit.instance_methods(false)
  #=> [:a, :a=, :b, :b=, :c, :c=, :d, :d=, :e, :e=, :f, :f=, :g, :g=, :h, :h=]
h.d
  #=> {:e=>{:f=>"cat"}}
h.d = "cat"
h.d
  #=> "cat"
