Automatically run whenever -w?

[ra...@heartlandmacs.com]

Hello All, 

I'm kind of a n00b, so please forgive me if this is super easy or really stupid, but I'm trying to use whenever in a way that I think it was not originally intended. Basically I made an app for a school bell system so that school admins can set and change times for bells to ring on a webpage, and then whenever makes the schedule. However, I have to manually run `whenever -w` each time they make a change. I've tried to have whenever run a script, but that doesn't seem to work. The task in 'schedule.rb' that calls the 'run_whenever.rb' script does work, I can see that it's being called by cron in my logs, but the crontab does not update. Does anyone have any suggestions? My files are as below:

/config/schedule.rb:

##################################################

require File.expand_path(File.dirname(__FILE__) + "/../config/environment")

set :path, Rails.root

set :output, Rails.root.join('log', 'cron.log')

Schedule.find_each { |schedule|

every %(#{schedule.min} #{schedule.hour} * * #{schedule.dow}) do

command "/home/dev/Herrald/play.sh"

end

 }

every 15.minutes do

command "/home/dev/Herrald/run_whenever.rb"

end

##########################################

run_whenever.rb:

################################

#!/usr/bin/env ruby

Dir.chdir("herrald_web") do

  system "whenever -w &"

end

##################################

crontab -l result:

#################################
