    Set ``list_display_links`` to control which fields in ``list_display``

    should be linked to the "change" page for an object.

    Use ``list_display_links`` to control if and which fields in

    :attr:`list_display` should be linked to the "change" page for an object.

    By default, the change list page will link the first column -- the first

    field specified in ``list_display`` -- to the change page for each item.

    But ``list_display_links`` lets you change which columns are linked. Set

    ``list_display_links`` to a list or tuple of fields (in the same

    format as ``list_display``) to link.

    But ``list_display_links`` lets you change this:

    ``list_display_links`` can specify one or many fields. As long as the

    fields appear in ``list_display``, Django doesn't care how many (or

    how few) fields are linked. The only requirement is: If you want to use

    ``list_display_links``, you must define ``list_display``.

    * Set it to ``None`` to get no links at all.

    * Set it to a list or tuple of fields (in the same format as

      ``list_display``) whose columns you want converted to links.

      You can specify one or many fields. As long as the fields appear in

      ``list_display``, Django doesn't care how many (or how few) fields are

      linked. The only requirement is that if you want to use

      ``list_display_links`` in this fashion, you must define ``list_display``.

    In this example, the ``first_name`` and ``last_name`` fields will be

    linked on the change list page::

            list_display = ('first_name', 'last_name', 'birthday')

            list_display_links = ('first_name', 'last_name')

    In this example, the change list page grid will have no links::

        class AuditEntryAdmin(admin.ModelAdmin):

            list_display = ('timestamp', 'message')

            list_display_links = None

    .. versionchanged:: 1.7

        ``None`` was added as a valid ``list_display_links`` value.

.. _admin-list-editable:

.. attribute:: ModelAdmin.list_editable

    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.

    It is expected to return either ``None`` or a ``list`` or ``tuple`` of field

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