converting ruby struct to yaml -

i have struct in ruby looks this:

struct.new("device", :brand, :model, :port_id) @devices = [  struct::device.new('apple', 'iphone5', 3),  struct::device.new('samsung', 'galaxy s4', 1) ] 

converting to_yaml gives me result:

--- - !ruby/struct:struct::device   brand: apple   model: iphone5   port_id: 3 - !ruby/struct:struct::device   brand: samsung   model: galaxy s4   port_id: 1 

however i'm still not sure how convert struct yaml whenever need use in code. when add devices: on top of yaml code , try parse ruby struct config['devices'] variable - don't results.

any appreciated!

i'm not seeing problem:

irb(main):001:0> require 'yaml' => true irb(main):002:0> struct.new("device", :brand, :model, :port_id) => struct::device irb(main):003:0> devices = [ irb(main):004:1*  struct::device.new('apple', 'iphone5', 3), irb(main):005:1*  struct::device.new('samsung', 'galaxy s4', 1) irb(main):006:1> ] => [#<struct struct::device brand="apple", model="iphone5", port_id=3>, #<struct struct::device brand="samsung", model="galaxy s4", port_id=1>] irb(main):007:0> y = devices.to_yaml => "---\n- !ruby/struct:struct::device\n  brand: apple\n  model: iphone5\n  port_id: 3\n- !ruby/struct:struct::device\n  brand: samsung\n  model: galaxy s4\n  port_id: 1\n" irb(main):008:0> obj = yaml::load(y) => [#<struct struct::device brand="apple", model="iphone5", port_id=3>, #<struct struct::device brand="samsung", model="galaxy s4", port_id=1>] 

you must make sure struct.new runs before yaml::load before .to_yaml. otherwise ruby doesn't know how create struct text.

okay, said, must run struct definition before trying load. plus trying build hash, use yaml syntax:

config.yml:

--- devices: - !ruby/struct:struct::device   brand: apple   model: iphone5   port_id: 3 - !ruby/struct:struct::device   brand: samsung   model: galaxy s4   port_id: 1 

and test.rb:

require 'yaml'  struct.new("device", :brand, :model, :port_id) config = yaml::load_file('./config.yml') unless defined? config  devices = config['devices'] puts devices.inspect 

result:

c:\>ruby test.rb [#<struct struct::device brand="apple", model="iphone5", port_id=3>, #<struct struct::device brand="samsung", model="galaxy s4", port_id=1>]
