Question

Sto seguendo un tutorial clickatell e il mio codice appare come segue. Tuttavia ho l'errore

Il mio codice simile a questo -

# controllers/sms.rb: 
require 'clickatell' 

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

Questo è il tuo routes.rb che è non senso:

ActionController::Routing::Routes.draw do |map| 
    map.resource :sms 
end 

Si dovrebbe piuttosto essere:

APP_NAME_HERE_CAMEL_CASE_STYLE::Application.routes.draw do 
    resource :sms 
end 

Sembra y o copia/incolla il vecchio codice Rails 2 in un'app Rails 3.
