I did the following to implement cron jobs in rails 3 using a "runner" instead of a rake task.

Step 1: I have whenever gem installed and scheduler.rb has following:

      set :environment, 'development'    set :output, {   :error    => "/log/error.log",   :standard => "/log/cron.log"     }      every 1.minute do    runner "Cron.sendAutomaticsSMS()"    end

Step 2:

Cron file: lib/cron.rb

        class Cron < ActiveRecord::Base          def **sendAutomaticsSMS**()           ----some code here ---        end      end

Step 3:

        whenever --update-crontab --set environment=development 

This updates crontab file.

Step 4:

Checked contents of crontab file using:

        crontab -e  

It opens cron tab file which has details of cron job method to be invoked:

---

        # Begin Whenever generated tasks for: store        # End Whenever generated tasks for: store        # Begin Whenever generated tasks for: /code/rails_projects/new/bhk/bigbhk-     dev/config/schedule.rb      * * * * * /bin/bash -l -c 'cd <*RAILS_APP_PROJECT_LOCATION*> && script/rails runner -e development '\''**Cron.sendAutomaticsSMS()**'\'' >$        # End Whenever generated tasks for: /code/rails_projects/new/bhk/bigbhk-dev/

Step 5:

Running cron job:

        $sudo service cron restart        cron stop/waiting      cron start/running, process 4027

This does not do anything. I wait for operation as defined in sendAutomaticsSMS() method to execute but the cron doesn't even enter this method.

You'll want to find where your cron logs to:

http://unix.stackexchange.com/questions/207/where-are-cron-errors-logged

And post any errors you find in there.

A first guess is that the environment cron is setting up for your task isn't the same as the one you use for development; are you using RVM or rbenv? Gemsets?
