parse json to object ruby

Question

I looked into different resources and still get confused on how to parse a json format to a custom object, for example

class Resident
  attr_accessor :phone,         


        

Answer 1

require 'json'

class Resident
    attr_accessor :phone, :addr

    def initialize(phone, addr)
        @phone = phone
        @addr = addr
    end
end

s = '{"Resident":[{"phone":"12345","addr":"xxxxx"},{"phone":"12345","addr":"xxxxx"},{"phone":"12345","addr":"xxxxx"}]}'

j = JSON.parse(s)

objects = j['Resident'].inject([]) { |o,d| o << Resident.new( d['phone'], d['addr'] ) }

p objects[0].phone
"12345"
