One way to wrap mundane things to a Sidekiq Worker perform method

publisher_worker_class_factory.rb

module Notification
  def self.publisher_worker_class(klass)
    Class.new do
      include(Sidekiq::Worker, Wisper::Publisher)
      sidekiq_options(:queue => :report)
      define_method :perform do |*args, **kwargs|
        success = false
        begin
          context = klass.new.perform(*args, **kwargs)
          broadcast(:deliveried_report_delivery, context)
          success = true
        rescue => e
          broadcast(:failed_report_delivery, context)
        ensure
          raise e unless success
        end
      end
    end
  end
end

# Alternativally, I used inheritance, making the subclasses to define a new method (perform2 or something).
# The superclass is the only one implementing the "perform" method, wrapping the call to the "perform2" method.
# Another one: Decorator.
#
# The main porpuse of saving this, is to remember the metaprogramming part, more than the actual problem,
# which I actually resolved diferently.
