Model class reference
=====================
.. currentmodule:: django.db.models
This document covers features of the :class:`~django.db.models.Model` class.
For more information about models, see :doc:`the complete list of Model
reference guides </ref/models/index>`.
Attributes
==========
``objects``
-----------
.. attribute:: Model.objects
Each non-abstract :class:`~django.db.models.Model` class must have a
:class:`~django.db.models.Manager` instance added to it.
Django ensures that in your model class you have at least a
default ``Manager`` specified. If you don't add your own ``Manager``,
Django will add an attribute ``objects`` containing default
:class:`~django.db.models.Manager` instance. If you add your own
:class:`~django.db.models.Manager` instance attribute, the default one does
not appear. Consider the following example::
from django.db import models
class Person(models.Model):
# Add manager with another name
people = models.Manager()
For more details on model managers see :doc:`Managers </topics/db/managers>`
and :ref:`Retrieving objects <retrieving-objects>`.
