#7505 closed (duplicate)

Abstract class managers have .model pointing to the Abstract rather than the real class

Description

Consider this example:

from django.db import models

class CustomManager(models.Manager):
    def get_query_set(self):
        print "My model is: ", self.model
        return super(CustomManager, self).get_query_set()

class Abstract (models.Model):
    class Meta:
        abstract = True
    objects = CustomManager ()

class Place(Abstract):
    name = models.CharField(max_length=50)
    address = models.CharField(max_length=80)

When this code is evaluated in ./manage.py shell, we get:

>>> models.Place.objects.model
<class 'demoproject.gentest.models.Abstract'>

>>> Place.objects.all()
My model is:  <class 'demoproject.gentest.models.Abstract'>

The normal behavior would be models.Place.objects.model to point to the "real" class - <class 'demoproject.gentest.models.Place'>
