Constructor Details

#initialize(message, data = {}) ⇒ Result

Use this to class to return results from service:

class MyService
  def perform
    if true
      Result.new "Next task created", next_task: next_task
    else
      Error.new "Failed"
    end
  end
end

and use in controller:

result = MyService.new.perform
if result.success?
  flash[:notice] = result.message
  redirect_to result.data[:next_task]
end

Note when iterating a huge objects, use ‘next_task_id` so Ruby Garbage Collector can clear all temp objects from the service run If you return some object which is not basic, it can not safely clear all temp objects
