title: Django admin console - Parse string to DateField
body: <p>Currently in our database the date field is entered as a string (ex: 11/7/2009). Is there anyway in my models.py file to convert this field from say a TextField to DateField so that in the Admin Console a user could select the date from the calendar view instead of having to enter it in manually? Perhaps parse it on the fly?</p>
  
  <p><code>date = models.TextField()</code></p>
  
  <p>convert to..</p>
  
  <pre><code>date = models.DateField()
  </code></pre>
