for regularly scheduled jobs, I use a mixture of cron (to create a delayed
job), and the delayed_job itself
the crontab instance is very light, just a small (non-rails) rb script to
insert the delayed_job in the delayed_jobs table
then the delayed_job instance will pickup the job and run it
in your instance, I would create a class method on the Test model -
something like
def self.remove_old_unpublished
delete_all(["created_at < ? and state in('unpublished')", 24.hours.ago])
end
cron entry like this:
05 1 * * * cd /path/to/current &&
RAILS_ENV=production
/path/to/current/lib/delayed_job_cron_jobs/create_delayed_job.rb
--model "Test" --method "remove_old_unpublished" --queue "general"
--arguments "{:any_argument => 42}"
the following gist is a script to insert delayed_jobs from cron

fyi, the reason to take this route over the simpler rake route (run rake
task from cron) is performance and memory usage - this method will save you
a bunch of both.
