How to setup Whenever gem in production (RVM)

Question

I've one rake task which i want to execute once every day: in production installed rvm

in schedule.rb i have

set :output, "/home/username/data/public_html/log/cron_log.log"
every 24.hours do
  rake "fetch:smth"
end

crontab -l shows me:

MAILTO="[email protected]"
PATH="/usr/local/rvm/rubies/ruby-1.9.3-p125/bin/ruby "
@daily cd /home/username/data/www/nameofsite.com && RAILS_ENV=production bundle   exec rake fetch:smth

truly, i'm a little bit confused, coz previously i didn't have experience with cron, so plz help.

EDIT #1

i've run rvm env -- path 1.9.3@global and it gave me:

PATH="/usr/local/rvm/gems/ruby-1.9.3-p125/bin:/usr/local/rvm/gems/ruby-1.9.3-p125@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p125/bin:/usr/local/rvm/bin:$PATH"

and then i've

MAILTO="[email protected]"
PATH="/usr/local/rvm/gems/ruby-1.9.3-p125/bin:/usr/local/rvm/gems/ruby-1.9.3-p125@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p125/bin:/usr/local/rvm/bin:$PATH"
@daily  RAILS_ENV=production rake rate:fetch

and when i run execute, from ISPmanager, it gave me: Exited with return code = 1 the link below says that if the exit error is 1, then there is already a /var/run/cron.pid file. and it's true, but i don't have root privileges

You don't need schedule.rb if you're calling the task from cron. That's handled by the @daily entry in crontab. Just set the logfile name as an environment variable and have the rake task refer to that. You'll probably also need more in your $PATH than just the path to the ruby binary, otherwise bundle isn't going to be found. While you're giving the path to a ruby, you're not actually selecting it for RVM to know what you mean, so it's not going to be able to find the right gemset. RVM provides wrappers which Do The Right Thing for this sort of task - replace bundle exec with /usr/local/rvm/wrappers/ruby-1.9.3-p125 -S bundle exec and it should work.

Hope that gives you some ideas. There's more here.

UPDATE #1

With Edit #1, you've fixed one problem and created another. You still need to cd to the app directory, otherwise rake won't find the Rakefile.
