For the default values in your hash you should use this

def some_method(required_1, required_2, options={})
  defaults = {
    :option_1 => "option 1 default",
    :option_2 => "option 2 default",
    :option_3 => "option 3 default",
    :option_4 => "option 4 default"
  }
  options = defaults.merge(options)

  # Do something awesome!
end
