Rails + batch jobs

Hey,

I’m wondering how to run a batch job on a rails server. And would this
be possible on a shared hosting like bluehost? what about capistrano?

thnx in advance,
DP

Hi Daan,
If your trying to run a job that will need to be run from time to
time manually, then you should write a rake task and put it in your
lib/tasks/ directory. If your trying to run something automated then
you need to look at BackgroundRB [1] or RailsCron[2]. Note that
RailsCron is no longer supported, but I still like it better than
BackgroundRB.

Good Luck,
Rob K.

Hey,

I tried installing backgroundrb by following the Readme, but i always
get errors when i try to start up the server. I’ve installed Slave
1.0.0, Daemons 1.0.3 and the plugin from the bgrb site.

This is the error i get

I just found out that the new release of BgRB doesn’t work on Rails, my
friend has it working on mac. Now my question is will it work on
Bluehost ? Or is there an alternative that works under windows ?
