Backgroundrb devel - Feb 2007 - cron like behaviour?

Hi

I have previously used railscron for server-side manipulation of the
database but had a heap of trouble working with it.
BackgrounDRB was suggested to me by a friend.

I upload some files via acts_as_attachment and these go lie in a dir
structure that i desire. What I want from the background process is to
periodically (not user initiated) do some file-structure manipulation i.e. I
want to move some of the files into different directory structures/create
symlinks from different locations.

What bugs me is how I get a worker to do_some_work without a user event.

I will greatly appreciate some pointers.

Thanks a lot.
Ivor

Ivor -

Sounds like BackgroundRb is a good solution for your problem.
You define scheduled jobs in a file /config/backgroundrb_schedules.yml
-- these will get fired off on the interval you set.

Here''s what my backgroundrb_schedules.yml looks like:

scheduled_publisher:
  :class: :scheduled_publish_worker
  :job_key: :scheduled_publisher
  :worker_method: :do_publish
  :worker_method_args: scheduled workers require some args, so here you go...
  :trigger_args:
      :start: <%= Time.now + 5.seconds %>
      :repeat_interval: <%= 1.minutes %>

This kicks off a worker that checks for pending publications every minute.

Note the :worker_method_args -- field. I found that if you do not
provide a value for this field your scheduled worked won''t run. My
scheduled_publish_worker doesn''t need any args -- so I provided a
placeholder value for :worker_method_args.
