Helper Methods inside of a Controller

When needing to include a helper method inside of a controller, instead of including the ENTIRE helper module, simply use this method like so:

module ApplicationHelper
  def fancy_helper(str)
    str.titleize
  end
end

class MyController < ApplicationController
   def index
     @title = view_context.fancy_helper "dogs are awesome"
   end
end

view_context
