我正在使用rails ActiveJob的delayed_job适配器,但是仍然能够访问delayed_job的错误和故障挂钩,以便在作业出错或失败时触发通知邮件程序.

我想我已经跟踪了我需要扩展的ActiveJob代码片段,以便合并delayed_job的错误和失败方法.

如何扩展下面的JobWrapper类以包含delayed_job的错误和失败方法,以便我可以逐个使用自定义错误/失败代码？

require "delayed_job"

module ActiveJob

  module QueueAdapters

    class DelayedJobAdapter

      def enqueue(job)
        delayed_job = Delayed::Job.enqueue(JobWrapper.new(job.serialize), queue: job.queue_name, priority: job.priority)
        job.provider_job_id = delayed_job.id
        delayed_job
      end

      def enqueue_at(job, timestamp)
        delayed_job = Delayed::Job.enqueue(JobWrapper.new(job.serialize), queue: job.queue_name, priority: job.priority, run_at: Time.at(timestamp))
        job.provider_job_id = delayed_job.id
        delayed_job
      end

      class JobWrapper
        attr_accessor :job_data

        def initialize(job_data)
          @job_data = job_data
        end

        def perform
          Base.execute(job_data)
        end
      end
    end
  end
end
