Ruby Ruby Modules Include and Extend Being Included

Define an included class method in the Fetcher module that takes one argument called klass.

I can not figure this out for the life of me.

included.rb
module Fetcher
  def fetch(item)
    puts "I'll bring that #{item} right back!"
    def self.included(klass)
  end
  end
end

class Dog
  include Fetcher
  attr_reader :name
  def initialize(name)
    @name = name
  end
end

dog = Dog.new("Fido")
dog.fetch("thing")

Your class method code is actually correct, but the one mistake here is that it is not supposed to be placed within the fetch method; it needs to be inside the Fetcher module but outside of the fetch method.

module Fetcher
  def fetch(item)
    puts "I'll bring that #{item} right back!"
  end

  # define included class method
  def self.included(klass)
  end
end
