title: Rails way to reset seed on id field
body: <p>I have found the "pure SQL" answers to this question. Is there a way, <strong><em>in Rails</em></strong>, to reset the id field for a specific table?<br>
  Why do I want to do this? Because I have tables with constantly moving data - rarely more than 100 rows, but always different. It is up to 25k now, and there's just no point in that. I intend on using a scheduler internal to the Rails app (rufus-scheduler) to run the id field reset monthly or so.</p>
