How do I configure ActiveJob to use Resque?

I am having a bit of difficulty with ActiveJob in Rails 4.2 and Resque.

I've installed redis and I've added resque and resque-scheduler to my Gemfile.

I've created a test job - it is just the generated file

rails g job test

but I keep getting errors about ActiveJob not defined 

NameError: uninitialized constant ActiveJob

or missing method when I switch the adapter like this 

config.active_job.queue_adapter = :resque

I get this error

/usr/local/lib/ruby/gems/2.1.0/gems/railties-4.2.0.beta1/lib/rails/railtie/configuration.rb:95:in `method_missing': undefined method `active_job' for #<Rails::Application::Configuration:0x007f97ba98a5b8> (NoMethodError)

I've even looked at the source code but I have no idea. It is just calling super.

https://github.com/rails/rails/blob/master/railties/lib/rails/railtie/configuration.rb#L95

What I am missing? Why doesn't the queue adapter work? Does anyone know how to fix this?

Add them the Gemfile with gem 'resque' and gem 'resque-scheduler' and bundle install. We'll also need to create a Resque configuration file:

#config/initializers/resque.rb

Resque.redis = Redis.new(:host => "localhost", :port => 6379)

We'll also require the Resque and Resque Scheduler rake tasks, so we can start our workers and scheduler with rake: #lib/tasks/resque.rake

require 'resque/tasks'
require 'resque/scheduler/tasks'

namespace :resque do
  task :setup do
    require 'resque'
    require 'resque-scheduler'
  end
end

We can now start a worker with QUEUE=* rake environment resque:work. If everything's working right, we should be able to see it in the Resque console. Run resque-web and visit http://0.0.0.0:5678/overview.

All we really need to do is configure it to use the Resque adapter.

#config/initializers/active_job.rb

ActiveJob::Base.queue_adapter = :resque

Now adding Jobs and enquing them should work as expected. Also try updating rails gem if you see undefined ActiveJob.

I turns out that I had selected which frameworks I was using.

# config/application.rb 
require "active_model/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"

The way to fix it, is to add the Active Job framework in the application.rb file.

require "active_job/railtie"

Or to load all of Rails

require 'rails/all'

This seems to be working now.
