How do I use define_method to create class methods?

Question

This is useful if you are trying to create class methods metaprogramatically:

def self.create_methods(method_name)
    # To create instance methods:
    defi         


        

Answer 1

To be used in Rails if you want to define class methods dynamically from concern:

module Concerns::Testable
  extend ActiveSupport::Concern

  included do 
    singleton_class.instance_eval do
      define_method(:test) do
        puts 'test'
      end
    end
  end
end
