title: how can I change the format of a datefield in models?
body: <p>I want store some data in my django model class. The dates I need to store are of the form mm/dd/yy but the django date field format by default is yyyy-mm-dd so i get this error django.core.exceptions.ValidationError: ["'10/05/1997' value has an invalid date format. It must be in YYYY-MM-DD format."]
  . how can i resolve this issue? I am not using any forms so I cannot use forms.datefield and its a datefield and not a datetimefield</p>
