title: Rails 3 - is possible to run an action after ending the first?
body: <p>I am interesting about an option to run an action in a moment, when is ending the currently action.</p>
  
  <p>More specifically, I want to run an action for download files from my page and after downloading all files this action is ending (usually behavior - this action is running by CRON). </p>
  
  <p>And now I would like to automatically run the second action. This action will be checking the downloaded files...</p>
  
  <p>Exist any way, how to do?
  Thank you a lot,</p>
  
  <p>M.</p>
