title: Django - Get only date from datetime.strptime
body: <p>I have start date field in database as date (not datetime). In my save method in forms.py I'm using <code>datetime.strptime(date_string, '%Y-%m-%d')</code> to convert string to date. The method returns me formatted date along with time, i.e, "2006-08-03 00:00:00".</p>
  
  <p>I want just the date and no time. Because I get an "invalid date format error" saying "It must be in YYYY-MM-DD format", I'm stuck on this and frustrated.  Can anyone help me out with this? </p>
