title: Custom Manager to filter objects on site but not in admin?
body: <p>I followed <a href="http://terrarum.net/development/soft-deleting-with-django.html" rel="noreferrer">this example</a> and it works great but I'm wondering if I can put in an exception so that when I am in the admin all objects show up (active and inactive). This might be simple but I can't find how to do it in the docs.</p>
  
  <p>Here's what my manager looks like now:</p>
  
  <pre><code>class ShareManager(models.Manager):
      def get_query_set(self):
          return super(ShareManager, self).get_query_set().filter(active=True)
  </code></pre>
