Using number_with_precision on application_controller in rails3

Question

I did add require 'action_view' & include ActionView::Helpers::NumberHelper ⬇

class ApplicationController < ActionController::Base

  require 'action_view'
  include ActionView::Helpers::NumberHelper

And, when I call it in my => def self.form_price formatted_price, total, total_till

puts number_with_precision(total, :precision => 2, :delimiter => ',')

Get this message:

.rvm/gems/ruby-1.9.3-p327/gems/railties-3.2.13/lib/rails/commands/runner.rb:53:in `eval': undefined method `number_with_precision' for ApplicationController:Class (NoMethodError)

Why are you putting this in your controller? It should be in the view, or better yet a decorator. — Alex Peachey, Apr 09 '14 at 06:10
