Delayed job, undefined method `taskmy' for class `Batch

Question

I am trying to use delayed_job to run some code in background and give the user some response immediately.

class Batch

  def self.taskmy
    # some very long task
  end
  def taskmy
      self.taskmy
  end
  handle_asynchronously :taskmy
end

My controller action look like below

def send_command
    count = 0
    count2 = 0
    Batch.delay.taskmy
    puts count
    puts count2
end

But i get an error

ActiveRecord::ConnectionNotEstablished: No connection pool with id primary > > found

I started the job with

rake jobs:work

I was using the active record gem with mongodb. i included following in my gemfile and restarted the job. gem 'delayed_job_mongoid'
