ruby-on-rails – 未初始化的常量ActionDispatch :: Routing :: Routes(NameError)

我正在关注clickatell教程,我的代码如下所示.但是我得到了错误

uninitialized constant ActionDispatch::Routing::Routes (NameError)

    from /Users/user1/Desktop/rails_projects/clickatellsms/config.ru:1

我的代码看起来像这样 –

# 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

解决方法

那是你的routes.rb是没有意义的：

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

它应该是：

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

看起来你在Rails 3应用程序中复制/粘贴了旧的Rails 2代码.
