title: django models timer delete
body: <p>I am trying to put a timer on each object that is created
  after the time is up the object will delete itself</p>
  
  <p>I have my models set up so far I can see if I create an object and I can see my Gamesplayed object with all the data on HTML</p>
  
  <p>is there a way to add another field to the Gamesplayed of a countdown timer that will be shown on HTML and will delete the objects after the time is up?</p>
  
  <p>my models</p>
  
  <pre><code>from django.db import models
  
  class Gamesplayed(models.Model):
     Game=models.CharField(max_length=30,blank=True)
     Myviews = models.CharField(max_length=30,blank=True)
     Price=models.PositiveIntegerField()
  </code></pre>
  
  <p>is there any field that dose that? saw Durationfield but not sure how to use</p>
