How to get the cron working when using Javan-whenever in Rails

Question

I have setup my schedule.rb file as follows.

set :cron_log, "/log/cron_log.log"
if Rails.env.development?
  every 1.minute do
    runner "SomeModel.move_values"
    runner "SomeOtherModel.dispense"
   end
end

I also make it work in development mode by whenever --update-crontab trunk --set environment=development

But my model methods (class methods) are never called. Is there some way I can verify if its configured right. when I simply use update it resets the settings to use the production environment.

Hi Sid I just got done using that same javan-whenever plugin.

In your rails project, type crontab -l. If you see the crontab properly generated then you know it's either the code or some server thing.

You may want to consider doing set :environment, RAILS_ENV in your schedule.rb file to set the environment dynamically.

Ryan Bates has done a good screencast on this: http://railscasts.com/episodes/164-cron-in-ruby

Also, after I got done implementing this I also found this site: webbasedcron it looks much easier than javan-whenever.
