.. method:: ModelAdmin.get_list_display_links(self, request, list_display)

    .. versionadded:: 1.4

    The ``get_list_display_links`` method is given the ``HttpRequest`` and

    the ``list`` or ``tuple`` returned by :meth:`ModelAdmin.get_list_display`.

    It is expected to return a ``list`` or ``tuple`` of field names on the

    changelist that will be linked to the change view, as described in the

    :attr:`ModelAdmin.list_display_links` section.

.. method:: ModelAdmin.get_urls(self)

    The ``get_urls`` method on a ``ModelAdmin`` returns the URLs to be used for

:meth:`~django.contrib.admin.ModelAdmin.get_ordering` for specifying the

ordering dynamically (e.g. depending on the request) has also been added.

``ModelAdmin.save_related()``

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

New ``ModelAdmin`` methods

~~~~~~~~~~~~~~~~~~~~~~~~~~

A new :meth:`~django.contrib.admin.ModelAdmin.save_related` hook was added to

A new :meth:`~django.contrib.admin.ModelAdmin.save_related` method was added to

:mod:`~django.contrib.admin.ModelAdmin` to ease the customization of how

related objects are saved in the admin.

Two other new methods,

:meth:`~django.contrib.admin.ModelAdmin.get_list_display` and

:meth:`~django.contrib.admin.ModelAdmin.get_list_display_links`

were added to :class:`~django.contrib.admin.ModelAdmin` to enable the dynamic

customization of fields and links to display on the admin

change list.

Admin inlines respect user permissions
