Activejob::Lock

When you want only one instance of your job queued at a time.

Installation

Add this line to your application's Gemfile:

gem 'activejob-lock'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activejob-lock

Usage

require 'activejob/lock'

class MyLockedJob < ActiveJob::Base
  lock_with do |record, message|
    record
  end

  def perform(record, message)
    record.do_work
  end
end

There will never be two MyLockedJob for the same record enqueued at the same time.

Currently works only for resque. Contributions are welcomed for other backends.
