+==== Using a custom manager for the admin ====
+
+Sometimes you'll ant to use a different manager for the admin displays (e.g. to display only objects matching some criteria in the admin).  You can do this by defining the {{{manager}}} option in your {{{Admin}}} declaration:
+
+{{{
+#!python
+
+class LivingPeopleManager(models.Manager):
+    def get_query_set(self):
+        return super(LivingPeopleManager, self).get_query_set().filter(is_alive=True) 
+
+class Person(models.Model):
+    name = models.CharField(maxlength=50)
+    is_alive = models.BooleanField()
+    
+    class Admin:
+        manager = LivingPeopleManager()
+
+}}}
+
+(see "You can override default QuerySets" for more on QuerySets)
+
 === Added a more powerful way of overriding model methods, removed hard-coded _pre_save(), _post_save(), etc. ===
