Rails config file Object I like to use

rails_config_file.rb

class ConfigFile
  attr_reader :config_name
  attr_reader :context

  def self.read_with_env(*args)
    new(*args).read_with_env
  end

  def self.read(*args)
    new(*args).read
  end

  def initialize(config_name, options = {})
    @config_name = config_name.to_s
    @context = (options[:context] || "config").to_s
    @bind = options[:binding]
  end

  def read
    yamled
  end

  def read_with_env
    read[Rails.env]
  end

  private

  def yamled
    YAML.load(erbed)
  end

  def erbed
    ERB.new(file).result(@bind || binding)
  end

  def file
    @file ||= File.read(Rails.root.join(context, "#{config_name}.yml"))
  end
end
