whenever: Whenever gem (cron job) not executing rake task, Rails 4

I am trying to run rake task using whenever gem, did everything what was required but fro some reason cant execute the task successfully.

schedule.rb

set :environment, "development"
set :output, {:error => "log/cron_error_log.log", :standard => "log/cron_log.log"}

every 1.minute do
  rake "notify:user"
end

notify_user.rake

namespace :notify do
  desc "Rake task to push divisions"
  task :user => :environment do
    t = Division.trigger_divisions
    puts "#{Time.now} - Success!" + t.to_s
  end
end

I did whenever --update-crontab and also crontab -l

# Begin Whenever generated tasks for: /home/usman/projects/Saloon/config/schedule.rb
* * * * * /bin/bash -l -c 'cd /home/usman/projects/Saloon && RAILS_ENV=development bundle exec rake notify:user --silent >> log/cron_log.log 2>> log/cron_error_log.log'

# End Whenever generated tasks for: /home/usman/projects/Saloon/config/schedule.rb

# Begin Whenever generated tasks for: store

# End Whenever generated tasks for: store

Log are showing grep CRON /var/log/syslog

Not sure what i am doing wrong here. If i run

cd /home/usman/projects/Saloon && RAILS_ENV=development bundle exec rake notify:user task executes successfully.

Hi all, I was having the same issue, and found out that the system wasn’t finding the “bundle” command. The solution was to add

set :output, "log/cron_log.log" env :PATH, ENV['PATH']

to config/schedule.rb

The first line lets you debug any further whenever/cron issues by adding a log file to your production app. The second line ensures that the bundle command is available.

I think option 1.minute is not working properly.

Cronjobs have a granularity of 1 minute, so five asterisks means “run every minute.” The output is correct in this case.

The output for 2 minutes is correct, though definitely too verbose. It could simply be written as */2 * * * * /bin/bash -l -c 'cd /directory && RAILS_ENV=development bundle exec rake application:capture_price --silent >> log/cron_log.log 2>> log/cron_error_log.log'

What worked for me here was adding

set :job_template, nil

to config/schedule.rb This might lead to different issues though since the readme states that running the command through bash is needed for RVM to work, so YMMV.

@nicolasconnault thanks for the solutions. Works like a charm!
