Question

我正在使用Something.delay.some_function（）的延迟作业我正在运行[Foreman] [1] Procfile来启动rails服务器和一个worker

web: bundle exec rails s
worker:  bundle exec rake jobs:work

我一直在终端看到这个，虽然我总是经营佣金工作：如果在工作期间发生了不好的事情，请说清楚。现在我没有工作岗位

irb(main):010:0> Delayed::Job.all
  Delayed::Backend::ActiveRecord::Job Load (0.7ms)  SELECT "delayed_jobs".* FROM "delayed_jobs" 
=> []

但我仍然在终端看到那些奇怪的东西。这是什么以及如何摆脱它？

延迟作业检查是否每隔一段时间就有新任务。只要rake jobs:work正在运行，您就会看到这些日志。简而言之 - 一切都很好！

Ruby，延迟作业，延迟：后端：Activerecord
