ActiveJob Status

Provides interface for ActiveJob to allow the passing of status information for running jobs.

This gem uses callbacks implemented within ActiveJob and ActiveSupport::Cache to values to track job status and allow the passing of job completion information.

Cached information is set to expire after 72 hours to prevent memory exhaustion issues.

Add this line to your application's Gemfile:

gem 'job_status'

And then execute:

$ bundle

Or install it yourself as:

$ gem install job_status

JobStatus needs to have a store configured to be used for the cache. Any ActiveSupport::Cache store is acceptable. The simplest to use is ActiveSupport::Cache::MemoryStore, to use the store configure an initializer within you application to set the store.

# config/initializers/active_job_status.rb
JobStatus.store = ActiveSupport::Cache::MemoryStore.new

Other memory stores are available, for example it is possible to use the Redis based store or MemCache based store.

Create ActiveJob worker as normal and add the callback handlers and class methods for reporting status.

class MyJob < ActiveJob::Base
  include JobStatus::TrackedJob

  queue_as :urgent

  def perform(*args)
    # Set the total for a percentage
    total(job_id: @job_id, total: 100)

    # Do Stuff...
    # Set current status through
    at(job_id: @job_id, at: 95)

    # Store data to be retrieved
    store(job_id: @job_id, store: [{test: 1, name: "test"},{test: 2, name: "test 2"}])
  end
end

You can check the status of the job using the ActiveJob job_id.

my_job = MyJob.perform_later
JobStatus::Status.get_status(job_id: my_job.job_id)
# => :queued, :working, :completed
