YAML library not working in rails app?

Question

I have this code in an app/lib folder:

require 'yaml'

class YamlParser
  def parse
    data = YAML.load_file("#{Rails.root}/config/application.yml")
    require 'pry' ; binding.pry
    data[:production]
  end
end

YamlParser.new.parse

Why isn't it working? I am getting this error message:

uninitialized constant YamlParser::Rails (NameError)

Have you autoloaded the file and also before you use this you may have to require the file. `require 'yaml_parser.rb'` — Pramod Solanky, Apr 14 '15 at 14:15

Add this to your application.rb

config.autoload_paths += %W(#{config.root}/lib)

but I put my file in app/lib which should be eagerly loaded right? – Jwan622 Apr 14 '15 at 14:19

nope, it doesn't as of Rails 3 http://stackoverflow.com/questions/4073856/rails-3-autoload – davids Apr 14 '15 at 14:23
No, I think it does load app/lib. I made an app/lib folder. The post is referring to just the straight Rails.root/lib folder. – Jwan622 Apr 14 '15 at 15:39

My fault! By `app/lib` I understood `project_folder/lib`. Anyway, I would encourage you to use `project_folder/lib`. – davids Apr 14 '15 at 16:52

Ah, my class YamlParser was located in a file called "yaml_parse.rb" and not "yaml_parser.rb". I am bad at naming convention.
