Hook before all delyed job success callback to save successfully completed jobs

问题

Objective:

To save successfully completed jobs

Methods used

Have looked at this answer which tells how to save completed jobs and this answer which suggests to create a plugin which will be executed after one of lifecycle events.

Problem

There are following lifecycle events, and applicable arguments as present in code:

  :enqueue    => [:job],
  :execute    => [:worker],
  :loop       => [:worker],
  :perform    => [:worker, :job],
  :error      => [:worker, :job],
  :failure    => [:worker, :job],
  :invoke_job => [:job]

I had expected there will be some event corresponding to success, I am not getting which one will be executed after job is successful.

Some Code

With the help of above tow answers, I have created this plugin to save completed job and put in config/initializers/save_completed_delayed_job.rb

module Delayed
  module Plugins
    class SaveCompletedDelayedJobPlugin < Plugin
      callbacks do |lifecycle|
        # see below for list of lifecycle events
        lifecycle.after(:perform) do |job|
          p "This should be ran after success so that I can save the job in different table"
          CompletedDelayedJob.create({
            priority: job.priority,
            attempts: job.attempts,
            handler: job.handler,
            last_error: job.last_error,
            run_at: job.run_at,
            failed_at: job.failed_at,
            completed_at: DateTime.now,
            queue: job.queue
            })
          end
      end
    end
  end
end

Delayed::Worker.plugins << Delayed::Plugins::SaveCompletedDelayedJobPlugin

Why I need plugin

I can not use callback methods as I don't have dedicated job classed, I am using following code to queue job.

handle_asynchronously :deliver_delayed, :queue => 'my_q'
