title: Generating a report by date range in rails
body: <p>How would you go about producing reports by user selected date ranges in a rails app?  What are the best date range pickers? </p>
  
  <p>edit in response to patrick : I am looking for a bit of both widget and active record advice but what I am really curious about is how to restfully display a date ranged list based on user selected dates. </p>
