【问题描述】：

我正在尝试让 active_job 与 delay_job 一起工作。一切工作正常......因为代码按预期执行，但delayed_job 条目报告出现错误。我得到的错误如下。

ProcessEventJob 是我在app/jobs/process_event_job.rb 中的工作类。

class ProcessEventJob < ActiveJob::Base
  queue_as :event_handler_cycle

  def perform(event)
    Events::EventHandler.new(raw_data: event).call
  end
end

我用它来称呼它

ProcessEventJob.perform_later(params)

我已经重启了服务器和delayed_jobs。确保它在正确的环境变量下运行。不太确定还能做什么。我也可以从控制台正常访问 ProcessEventJob。

我认为 app 文件夹中的文件会自动需要。

任何关于如何调试它的想法将不胜感激。

注意下面的代码调用了延迟的作业。它是我们用来捕获事件的暴露端点。

module Api
  module V1
    class SegmentEventsController < ApiController
      def create
        begin
          ProcessEventJob.perform_later(params)
          render_success
        rescue StandardError => e
          render_fail
        end
      end

      private

      def render_success
        render status: 200, json:  "success" => "true" 
      end

      def render_fail
        render status: 400, json:  "success" => "false" 
      end

      def restrict_access
        unless ApiKey.exists?(access_token: params[:access_token])
          head :unauthorized
        end
      end
    end
  end

所以我似乎取得了一些进展，但仍然没有意义。我的登台设置运行了多个应用程序。其中两个使用delayed_jobs。

我认为这两者之间可能发生了一些冲突，所以我停止了我不需要的延迟工作，突然间一切都开始正常工作了。我遇到了一个post，它说如果你使用 -i 可以运行两个实例 ...

我不确定这是否是我正在寻找的。

【问题讨论】：

从哪里调用 ProcessEventJob？

查看从哪里调用它的编辑。

如果您手动需要process_event_job.rb，可能在初始化程序中，这是否有效？

那行不通。如果我能提供更多信息，请告诉我。

【参考方案1】：

您的application.rb 中有config.active_job.queue_adapter = :delayed_job 吗？

我有这个文件script/delayed_job 包含

#!/usr/bin/env ruby

require File.expand_path(File.join(File.dirname(__FILE__), '..', 'config', 'environment'))
require 'delayed/command'
Delayed::Command.new(ARGV).daemonize

然后在服务器上输入你的项目目录并运行

RAILS_ENV=staging bundle exec script/delayed_job start

【讨论】：

是的。那是行不通的。它在我们的本地机器上运行良好，但我们无法让它在我们的暂存环境中运行。

您可以粘贴用于在暂存时启动延迟作业的命令吗？
