juandebravo/hash-serializer

Convert a specific object to Hash format

INTRODUCTION

The aim of this gem is to enable an easy way to serialize an object in a Hash object or a JSON data structure using attributes name as keys.

This can be useful if you need to work with XSD schemas while using code generators that convert an schema in ruby objects but still you haven't a way to convert to JSON or any other format.

INSTALLATION

gem install hash-serializer

HOT TO USE v0.2.0

require 'hash-serializer'

class User
    attr_accessor :nickname
    attr_accessor :email
    attr_accessor :password

    def initialize(nickname = nil, email = nil, password = nil)
        @nickname = nickname
        @email = email
        @password = password
    end
end

u = User.new("juandebravo", "juan at pollinimini dot net", "*******")

HashSerializer.to_hash(u)
    => {"nickname"=>"juandebravo", "email"=>"juan at pollinimini dot net", "password"=>"*******"}

HashSerializer.to_hash(u, u.nickname)
    => {"juandebravo"=>{"nickname"=>"juandebravo", "email"=>"juan at pollinimini dot net", "password"=>"*******"}}

puts HashSerializer.to_json(u)
    => {"nickname":"juandebravo","email":"juan at pollinimini dot net","password":"*******"}

puts HashSerializer.to_json(u, "user")
    => {"user":{"nickname":"juandebravo","email":"juan at pollinimini dot net","password":"*******"}}

HOW TO USE v0.1.0

require 'hash-serializer'

class User
    attr_accessor :nickname
    attr_accessor :email
    attr_accessor :password

end

u = User.new("juandebravo", "juan at pollinimini dot net", "*******")

u.serialize_to_hash
    => {"nickname"=>"juandebravo", "email"=>"juan at pollinimini dot net", "password"=>"*******"}

u.serialize_to_hash(u.nickname)
    => {"juandebravo"=>{"nickname"=>"juandebravo", "email"=>"juan at pollinimini dot net", "password"=>"*******"}}

puts u.serialize_to_json
    => {"nickname":"juandebravo","email":"juan at pollinimini dot net","password":"*******"}

puts u.serialize_to_json("user")
    => {"user":{"nickname":"juandebravo","email":"juan at pollinimini dot net","password":"*******"}}

CHANGES

• v0.2.0 does not monkey patch Object class anymore. Always seems to be a bad idea this, so v0.2.0 is incompatible backwards.
