如何在IRB控制台中调试在delayed_job任务中运行的代码？

Question

I have a background task that runs using delayed_job.

I can see that it does run from the logging statements. It does not seem to have the correct result, compared to running it in the foreground, so I want to debug it in the IRB console.

I am running the background task with

rake jobs:work

and it does not trigger the debugger statement.

How can I load the debugger?

Answer 1

Start a standard rails console

ruby script/console

And start a worker inside here, this will see and trigger the debugger statement.

worker = Delayed::Worker.new
worker.start

Answer 2

I use pry as my console and remote debugger. Pry website here , Pry rails gem here . In your code, you add binding.pry statements to have your app stop executing and open the console. It works the same with delayed_job as it does with your rails app. Make sure you are running delayed_job in the foreground though, so it is still attached to the terminal. Eg, start delayed_job with:

rake jobs:work
