I am using sneakers gem to trigger actions on RabbitMQ But i can not start my service for triggering

I run the command 

WORKERS=MailerWorker rake sneakers:run

and I got the error as 

[INFO] 160825 14:26:46 :: LAUNCH worker
rake aborted!

My codes are below

# Rakefile
require_relative 'config/application'
require 'sneakers/tasks'

Rails.application.load_tasks


# config/initializers/sneakers.rb
Sneakers.configure({})
Sneakers.logger.level = Logger::INFO

# app/workers/mailer_worker.rb
require 'sneakers'
class MailerWorker
  include Sneakers::Worker

  from_queue "test.user.login", env: nil

  def work(raw_post)
    p "you are successful in this queue! #{raw_post.to_s}"
    ack! # we need to let queue know that message was received
  end
end

My RabbitMQ also have the message at exchange "test.user.login"

I followed this article but errors occurred Rails: How to listen to / pull from service or queue?

How can i run the sneakers without errors

Thanks

  • Hi @HieuPham, Thanks I have added this line require 'action_cable' to the file 'config/application.rb' It worked well – Thinh Huynh Aug 26 '16 at 03:45

The error says that ActionCable is not available in your script you should install/require it in your script.
