How To: Rails Background Jobs with ActiveJob

Rails' Active Job is a shared interface for working with asynchronous job queues. Among others, it has a queue adapter for Sneakers and it's very easy to set up.

Rails

As always, add sneakers to your Gemfile.

Set the queueing backend for your app to sneakers

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

In your `Rakefile`, add this:

```ruby
require 'sneakers/tasks'

Which will pull useful tasks for you.

rake sneakers:run       

Global configuration

Next, let's give you a place to configure global parameters for Sneakers; often this is all you'll do, or better, you won't need it and just use the default configuration.

Set up an initializer file, named after the sneakers gem.

# config/initializers/sneakers.rb
require 'sneakers'
Sneakers.configure( <your connection params, etc> )

Starting up

Generate a new job with rails generate job <name>, edit it then invoke the Sneakers rake task with:

WORKERS=ActiveJob::QueueAdapters::SneakersAdapter::JobWrapper rake sneakers:run
