ActiveJob does not use sidekiq in production environment

Question

I have upgraded my app to rails version 4.2.0.rc2. I try to use sidekiq as active_job backend. It works OK in development environment, but in production environment it uses Inline(mailers) instead of Sidekiq.

# config/initializers/active_job.rb 
Rails.application.configure do
  config.active_job.queue_adapter = :sidekiq
end

rails sever -e development

[ActiveJob] Enqueued ActionMailer::DeliveryJob (Job ID:...) to Sidekiq(mailers)

rails sever -e production

[ActiveJob] Enqueued ActionMailer::DeliveryJob (Job ID:...) to Inline(mailers) 

On console

$ rails c -e production
Loading production environment (Rails 4.2.0.rc2)
[1] pry(main)> Rails.configuration.active_job.queue_adapter
=> :sidekiq

What am I doing wrong?

Answer 1

I found solution. Instead of initializer put your queue_adapter config to application config.

# config/application.rb
module YourApp
  class Application < Rails::Application
    config.active_job.queue_adapter = :sidekiq
  end
end
