Ruby Module Method Access

Question

I have a ruby module for constants. It has a list of variables and 1 method which applies formatting. I can\'t seem to access the method in this module. Any idea why?

Answer 1

module Foo
  def self.hello # This is a class method
    puts "self.hello"
  end

  def hello # When you include this module, it becomes an instance method 
    puts "hello"
  end
end

Foo.hello #=> self.hello

class Bar
  include Foo
end

Bar.new.hello #=> hello
