djblets.db.managers¶

Managers for Django database models.

class ConcurrencyManager(*args, **kwargs)[source]¶

Bases: ClassDeprecatedMixin, Manager

A Django manager designed to work around database concurrency issues.

This was used in very old versions of Django where the get_or_create() method could raise IntegrityErrors due to concurrency. Since Django 1.0, the regular Manager has protections against this.

Deprecated since version 6.0: Because this is no longer necessary, this class has been deprecated and will be removed in Djblets 8.0. Any subclasses should change to just inherit from django.db.models.Manager.
