title: ActiveRecord - Get the last n records and delete them in one command?
body: <p>Hello all and thanks for taking the time to answer my question.</p>
  
  <p>The question is really explained in the title.</p>
  
  <p>I tried Model.last(n).destroy_all but none of that would work.</p>
  
  <p>I was wondering if it is possible to do it in one line, and if not what would be the cleanest way of doing it?</p>
  
  <p>Thanks again!</p>
