def get_changeform_initial_data(self, request):
return {'name': 'custom_initial_value'}
.. method:: ModelAdmin.get_deleted_objects(objs, request)
.. versionadded:: 2.1
A hook for customizing the deletion process of the :meth:`delete_view` and
the "delete selected" :doc:`action <actions>`.
The ``objs`` argument is a homogeneous iterable of objects (a ``QuerySet``
or a list of model instances) to be deleted, and ``request`` is the
:class:`~django.http.HttpRequest`.
This method must return a 4-tuple of
``(deleted_objects, model_count, perms_needed, protected)``.
``deleted_objects`` is a list of strings representing all the objects that
will be deleted. If there are any related objects to be deleted, the list
is nested and includes those related objects. The list is formatted in the
template using the :tfilter:`unordered_list` filter.
``model_count`` is a dictionary mapping each model's
:attr:`~django.db.models.Options.verbose_name_plural` to the number of
objects that will be deleted.
``perms_needed`` is a set of :attr:`~django.db.models.Options.verbose_name`\s
of the models that the user doesn't have permission to delete.
``protected`` is a list of strings representing of all the protected
related objects that can't be deleted. The list is displayed in the
template.
