Custom Rake Task 작성하기 

Cron jobs

using "whenever"

• crontab -l
• gem 'whenever'
• wheneverize .
• config/schedule.rb

config/schedule.rb

set :environment, :development

# path-to-bundler를 자신의 경로로 변경해야 함.
set :bundler_path, "/Users/hyo/.rbenv/shims"

set :output, {:error => 'log/error.log', :standard => 'log/cron.log'}

job_type :runner, "cd :path && :bundler_path/bundle exec rails runner -e :environment ':task' :output"

every 1.minute do
  runner "Cron::TestRunner.copy"
end

"whenever" 젬으로 cron job을 편리하게...
