Automatically include a Gem in a controller

I am currently working a gem that has some metlhods that I want to include into my controller classes, but I would like it to automatically include itself upon installation. So, for example, include MyGem, will not be required.

I tried using a railtie, but I am unsure if that is the right way since it doesn't work as far as I can tell. It looks similar to:

require 'my_gem'

module MyGem
  class Railtie < Rails::Railtie
  initializer "my_gem.method_items" do
   ActionController::Base.send :include, MethodItems
  end
 end
end

Any help would be great

module MyGem
  module InstanceMethods
    def foo
      "bar"
    end
  end
end

module MyGem
  class Engine < Rails::Engine
    initializer "testing" do |app|
      ActionController::Base.send :include, MyGem::InstanceMethods
    end
  end
end

Then in console:

ActionController::Base.instance_methods.grep(/foo/)
=> ["foo"]
