Rails 7.1 adds support for logging background job enqueue callers

Rails 7.1 has introduced a new option in Active Job that allows us to add support for logging background job enqueue callers. It provides information about the location from where a job was enqueued, which can be immensely helpful during debugging. The following is an example of what the log output looks like:

[ActiveJob] Enqueued NotifySubscribersJob (Job ID: 5945980f-303e-4c3f-af5b-e22be170f7c5) to Sidekiq(default)
[ActiveJob] ↳ app/models/post.rb:14 in `notify_subscribers`

By examining the logs above, we can determine that the NotifySubscribersJob was enqueued from the notify_subscribers method in the Post model, providing us with a clear picture of the job's origin.

To enable this functionality, we need to set the following configuration in config/environments/development.rb.

config.active_job.verbose_enqueue_logs = true

However, Rails 7.1 ships with this configuration set by default.

It's important to note that using verbose enqueue logs in a production environment is not recommended, as it uses the Kernel#caller method to retrieve the execution stack, which can be slow.
