class with ``try/except``.

.. exception:: Model.DoesNotExist
This exception is raised by the ORM in a couple places, for example by
:meth:`QuerySet.get() <django.db.models.query.QuerySet.get>` when an object
is not found for the given query parameters.
Django provides a ``DoesNotExist`` exception as an attribute of each model
class to identify the class of object that could not be found and to allow
you to catch a particular model class with ``try/except``. The exception is
a subclass of :exc:`django.core.exceptions.ObjectDoesNotExist`.
