Question

I am using rubygem delayed job but not able to run rake task successfully. I took reference of https://github.com/collectiveidea/delayed_job/tree/v2.0. BTW, i am using bundler.

#Gemfile
gem 'delayed_job', '~>2.0.4'

#Rake file
begin
  gem 'delayed_job', '~>2.0.4'
  require 'delayed/tasks'
rescue LoadError
  STDERR.puts "Run `bundle` to install delayed_job"
end

While running rake jobs:work --trace, it displays below error

rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
** Invoke jobs:work (first_time)
** Invoke merb_env (first_time)
** Execute merb_env
** Invoke environment (first_time)
** Execute environment
** Execute jobs:work
rake aborted!

Tasks: TOP => jobs:work

I tried Delayed Job Rake Task Failing but it didn’t solve my problem.

Can anyone describes what is happening here?
Thanks.

Ah! Debugging DJ is a pain in the you know what.

This error message:

=> Aonymous modules have no name to be referenced by

Means that you have spelled one of your models incorrectly.

For example: Categorizatoin instead of Categorizatoin.

So go through your Models in DJ and check your spelling on all of your models.
