Uninitialized constant ActionDispatch::Routing::Routes (NameError) - ruby-on-rails

Question

I'm following a clickatell tutorial and my code looks as follows. However I get the error

My code looks like this -

class SMS
def initialize(config)
#config = config
end
def create(recipient, message_text)
api.send_message(recipient, message_text)
end
private
def api
#api ||= Clickatell::API.authenticate(
#config[:api_key],
#config[:username],
#config[:password])
end
end
# config/clickatell.yml:
api_key: 9999999
username: abcdefg
password: hijklmno
# config/environments/development.rb
CLICKATELL_CONFIG = YAML.load(File.open(File.join(RAILS_ROOT,
'config', 'clickatell.yml')))
# config/routes.rb:
ActionController::Routing::Routes.draw do |map|
map.resource :sms
end
# app/views/sms/new.html.erb:
<% form_tag '/sms', :method => :post do -%>
<label>Enter the recipients mobile number:</label>
<%= text_field_tag "recipient" %>
<label>Enter your message:</label>
<%= text_area_tag "message_text" %>
<%= submit_tag "Send SMS" %>
<% end %>
# controllers/sms_controller.rb:
class SmsController < ApplicationController
def create
sms = SMS.new(CLICKATELL_CONFIG)
sms.create(params[:recipient], params[:message_text])
flash[:notice] = "Message sent succesfully!"
redirect_to :back
rescue Clickatell::API::Error => e
flash[:error] = "Clickatell API error: #{e.message}"
redirect_to :back
end
end

Answer 1

That's your routes.rb which is non sense:
ActionController::Routing::Routes.draw do |map|
map.resource :sms
end
It should rather be:
APP_NAME_HERE_CAMEL_CASE_STYLE::Application.routes.draw do
resource :sms
end
Looks like you copy/pasted old Rails 2 code within a Rails 3 app.
