django-softdelete Soft delete for Django ORM, with support for undelete. Can be tested directly with the following command: django-admin.py test softdelete --settings="softdelete.settings" Inspired by http://codespatter.com/2009/07/01/django-model-manager-soft-delete-how-to-customize-admin/ This project mostly exists to be able to provide undelete of soft-deleted objects, along with proper undeletion of related objects. Requirements: Django 1.3 django.contrib.contenttypes There are simple templates files in templates/. You will need to add Django's egg loader to use the templates as is: TEMPLATE_LOADERS = ( ... 'django.template.loaders.eggs.Loader', ) Add the project 'softdelete' to your INSTALLED_APPS for through-the-web undelete support. INSTALLED_APPS = ( ... 'django.contrib.contenttypes', 'softdelete', ) Central to the ability to undelete a soft-deleted model is the concept of changesets. When you soft-delete an object, any objects referencing it via a ForeignKey, ManyToManyField, or OneToOneField will also be soft-deleted. This mimics the traditional CASCADE behavior of a SQL DELETE. When the soft-delete is performed, the system makes a ChangeSet object which tracks all affected objects of this delete request. Later, when an undelete is requested, this ChangeSet is referenced to do a cascading undelete. If you are undeleting an object that was part of a ChangeSet, that entire ChangeSet is undeleted. Once undeleted, the ChangeSet object is removed from the underlying database with a regular ("hard") delete.
