title: Django - specify which model manager Django admin should use
body: <p>I've created a custom Manager for a Django model which returns a QuerySet holding a subset of objects.all(). I need this to be the model's default Manager, since I am also creating a custom tag which will retrieve content from any model (specified by an argument), and needs to use the default Manager for the specified model. All that works fine, except - Django Admin is ALSO using the default Manager for this particular model, which means that not all model instances appear in the admin.</p>
  
  <p>The Django docs don't help:</p>
  
  <blockquote>
    <p>If you use custom Manager objects, take note that the first Manager Django encounters (in
    the order in which they're defined in the model) has a special status. Django interprets this first Manager defined in a class as the "default" Manager, and several parts of Django (<strong>though not the admin application</strong>) will use that Manager exclusively for that model.

  <p>The admin isn't supposed to use the default Manager, but it seems to be in my case. Note that I have also explicitly add the default Manager <code>objects</code>:</p>
  
  <pre><code>subset = CustomManager() # the default manager
  objects = models.Manager() # the one I want admin to use
  </code></pre>
  
  <p>How can I specify which Manager the admin should use?</p>
