Set ruby 2.0 keyword arguments with attr_accessor on initialize

Question

How can I dynamically set without having to write the same code all over.

Right now the code looks like this:

def initialize(keywords: keywords, title: t         


        

Answer 1

def initialize(keywords: nil, title: nil, url: nil, adsetting: nil)
  local_variables.each do |k|
    v = eval(k.to_s)
    instance_variable_set("@#{k}", v) unless v.nil?
  end
end

or following John Ledbetter and Cary Swoveland's suggestion:

def initialize(keywords: nil, title: nil, url: nil, adsetting: nil)
  method(__method__).parameters.each do |type, k|
    next unless type == :key
    v = eval(k.to_s)
    instance_variable_set("@#{k}", v) unless v.nil?
  end
end
