OpenStructFactory

A factory to create OpenStruct objects from nested hashes and arrays.

The main difference with other gems such as recursive-open-struct is that this library is entirely decoupled: it doesn't inherit from OpenStruct and doesn't rely on any core extensions.

Installation

Add this line to your application's Gemfile:

gem 'open_struct_factory'

And then execute:

$ bundle

Or install it yourself as:

$ gem install open_struct_factory

Usage

require 'ostruct'
require 'open_struct_factory'

book_data = {
  title: "The World as Will and Representation",
  author: {
    name: "Arthur Schopenhauer",
    birth_date: "1788-02-22",
    birth_place: "Danzig",
  },
  publications: [
    {edition: "1st edition", year: 1818},
    {edition: "2nd expanded edition", year: 1844},
  ]
}

book = OpenStructFactory.create(book_data)

puts book.title
# => The World as Will and Representation

puts book.author.name
# => Arthur Schopenhauer

puts book.publications[1].year
# => 1844

A block can optionally be passed, it will be called for each key and give you the opportunity to sanitize the property name to be added to the OpenStruct:

data = {
  "SomePeople" => "LoveTheirCamelCase",
}

obj = OpenStructFactory.create(data) { |key| key.downcase }

puts obj.somepeople
# => LoveTheirCamelCase
