Ruby: module, require and include

Question

I\'m trying to use Ruby modules (mixins).

I have test.rb:

#!/usr/bin/env ruby
require_relative \'lib/mymodule\'

class MyApp
  include MyModule
  sel         


        

Answer 1

Your code is working - but including a module does not do what you think it does. The class including the module will not get the methods - the objects from this class will.

So this will work :

class MyApp
  include MyModule
end

my_app_object = MyApp.new
my_app_object.hallo # => hallo

my_app_object is an object of class MyApp, which has a mixins of module MyModule. Take a look there for a complete explanation of modules and mixins.
