## [message] Above is your schedule file converted to cron syntax; your crontab file  was not updated.
## [message] Run `whenever --help' for more options.

In User model i have definition self.weekly_update

def self.weekly_update
  puts "cronjobs is called in every minutes"
end

Your everything is correct, its just that you are saying to cron job to print something in background, so it is doing that and you are able to observe it.

Instead you should try create or destroy some records to feel the changes i think :)
