ruby-on-rails – Ruby,延迟作业,延迟：后端：Activerecord

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

虽然我总是在我的终端上看到这个,但是我总是在这里工作：如果在工作期间发生了不好的事情,请清楚.现在我没有工作

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,我怎么能摆脱它？
