How to share methods between rails sidekiq workers

Question

I have two sidekiq workers in a rails app and I'm wondering what the best way to share code between them would be.

class PriceReminderWorker
  include Sidekiq::Worker
  sidekiq_options queue: 'price_alerts'

  def method_to_share
    stuff
  end 
end

and

class PriceNotificationWorker
  include Sidekiq::Worker
  sidekiq_options queue: 'price_alerts'

  def method_to_share
    stuff
  end 
end

Would the 'rails/ruby way' to be inherit from a parent class, or add a new module perhaps?

Answer 1

I would use inheritance if it makes sense to you for example that PriceReminderWorker and PriceNotificationWorker are both a PriceWorker and the methods you want to share make sense in the PriceWorker context. For example in Rails it makes sense that all Models are an ApplicationRecord

I would include the methods in a Module, if the methods you want to share merely take advantage of some common "trait" that both classes share. For example in Ruby both the Array class and the Hash class share a "trait", they both implement a foreach method that can accept a block and call that block for each member of its collection. In this case both classes include the Enumerable module.

Answer 2

You can put your shared methods in a module and just include them into your worker classes.

module Workify
  def method_to_share
    puts "hooray we're DRY!"
  end
end

class PriceReminderWorker
  include Sidekiq::Worker
  sidekiq_options queue: 'price_alerts'
end

class PriceNotificationWorker
  include Sidekiq::Worker
  sidekiq_options queue: 'price_alerts'
end

Both worker classes now have access to the method defined in the module.
