Using a base class to simplify workers that subscribe to an event

1_old_worker.rb

class OldWorker 
  
  include Sidekiq::Worker
  
  def perform user_event_id
    user_event = UserEvent.find user_event_id
    user = User.find user_event.user_id
    user_application = user.find_application user_event.application_id
    # do something
  end
  
end

2_new_worker.rb

class UserEventSubscriber
  include Sidekiq::Worker
  
  def perform user_event_id
    @user_event_id = user_event_id
    execute
  end
  
  def user_event
    @user_event ||= UserEvent.find @user_event_id
  end
  
  def user
    @user ||= User.find user_event.user_id
  end
  
  def user_application
    @user_application ||= user.find_application user_event.application_id  
  end
  
end

class NewWorker < UserEventSubscriber

  def execute
    #do something, the values are set up for me
  end
