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()
