6358	Admin ChangeList bypasses model's custom manager	Ionut Ciocirlan <ionut.ciocirlan@…>	nobody	"When using a custom manager for Model.objects that overrides Manager.get_query_set(), the admin ChangeList disregards it. E.g.:
{{{
from django.db import models

class MyManager(models.Manager):
    def get_query_set(self):
        return super(MyManager, self).get_query_set().filter(mybool=False)

class MyModel(models.Model):
    mybool = models.BooleanField()
    objects = MyManager()
}}}

To reproduce it, add a MyModel object with mybool set to true. The item will appear in the list. While this might be (quite debatably) a good approach, it is inconsistent as trying to edit the object in admin will lead to a 404: object with primary key u'1' does not exist.
