heroku - rails tutorial chapter 10 sendgrid -


i'm newbie, , self-teaching myself via michael hartl's ruby on rails tutorial.

i've made far chapter 10 , have working in development after adding sendgrid push heroko rejected following:

 nomethoderror: undefined method `action' #<rails::application::configuration:0x007fc6e0b67778> 

i'm on rails 4.2.0. i'm @ loss wrong. here's production configuration:

  config.action_mailer.raise_delivery_errors = true   config.action_mailer.delivery_method = :smtp   host = 'salty-plateau-4554.herokuapp.com'   config.action_mailer.default_url_options = { host: host }   actionmailer::base.smtp_settings = {     :address        => 'smtp.sendgrid.net',     :port           => '587',     :authentication => :plain,     :user_name      => env['sendgrid_username'],     :password       => env['sendgrid_password'],     :domain         => 'heroku.com',     :enable_starttls_auto => true   } 

and gemfile:

source 'https://rubygems.org'  gem 'rails',                   '4.2.0' gem 'bcrypt',                  '3.1.7' gem 'faker',                   '1.4.2' gem 'carrierwave',             '0.10.0' gem 'mini_magick',             '3.8.0' gem 'fog',                     '1.23.0' gem 'will_paginate',           '3.0.7' gem 'bootstrap-will_paginate', '0.0.10' gem 'bootstrap-sass',          '3.2.0.0' gem 'sass-rails',              '5.0.1' gem 'uglifier',                '2.5.3' gem 'coffee-rails',            '4.1.0' gem 'jquery-rails',            '4.0.3' gem 'turbolinks',              '2.3.0' gem 'jbuilder',                '2.2.3' gem 'sdoc',                    '0.4.0', group: :doc  group :development, :test   gem 'sqlite3',     '1.3.9'   gem 'byebug',      '3.4.0'   gem 'web-console', '2.0.0.beta3'   gem 'spring',      '1.1.3' end  group :test   gem 'minitest-reporters', '1.0.5'   gem 'mini_backtrace',     '0.1.3'   gem 'guard-minitest',     '2.3.1' end  group :production   gem 'pg',             '0.17.1'   gem 'rails_12factor', '0.0.2'   gem 'puma',           '2.11.1' end
