Ardaíonn an ORM an eisceacht seo nuair nach bhfaightear réad a bhfuil súil leis. Mar shampla, ardóidh:: meth: .querySet.get é nuair nach bhfaightear aon rud do na cuardaigh ar leith.

\n

Soláthraíonn Django eisceacht ``doesNotExist ``mar thréith de gach rang samhail chun an aicme réad nach bhféadfaí a aimsiú a aithint, rud a ligeann duit eisceachtaí a ghabháil d'aicme samhail áirithe. Is é an eisceacht fo-aicme de:exc: Django.Core.Exceptions.ObjectDoesNotExist.

\nexception Model.NotUpdatedLink to this definition#
\n

This exception is raised when a forced update of a Model instance\ndoes not affect any rows.

\n

Django provides a NotUpdated exception as an attribute of each model\nclass to identify the class of object that could not be updated, allowing\nyou to catch exceptions for a particular model class. The exception is a\nsubclass of django.core.exceptions.ObjectNotUpdated and inherits\nfrom django.db.DatabaseError for backward compatibility reasons.

Ní mór do gach rang neamh-teibí: Class: ~Django.db.Models.Models.Model a bheith curtha leis a: class: ~Django.db.Models.Manager leis. Cinntíonn Django go bhfuil “Bainisteoir” réamhshocraithe ar a laghad agat i do rang samhail. Mura gcuireann tú do Bainisteoir ``féin leis, cuirfidh Django tréith ``objects` ina bhfuil sampla réamhshocraithe: ~django.db.models.manager. Má chuireann tú do thréith sampla féin:class: ~Django.db.Models.Manager leis, ní bhíonn an ceann réamhshocraithe le feiceáil. Smaoinigh ar an sampla seo a leanas:

\n
Code
from django.db import models\n\n\nclass Person(models.Model):\n    # Add manager with another name\n    people = models.Manager()\n
\n

</topics/db/managers> <retrieving-objects>Le haghaidh tuilleadh sonraí faoi bhainisteoirí samhlacha féach:doc: `Bainisteoirí agus:ref: `Rudaí a aisghabháil `.
