Interface

The features of the admin interface will depend on the tree type.

:doc:`Materialized Path <mp_tree>` and :doc:`Nested Sets <ns_tree>` trees have
an AJAX interface based on `FeinCMS`_, that includes features like
drag&drop and an attractive interface.

.. _FeinCMS: http://www.feincms.org

Model Detail Pages
~~~~~~~~~~~~~~~~~~

If a model's field values are modified, then it is necessary to add the fields '_position' and '_ref_node_id'. Otherwise, it is not possible to create instances of the model.

Example:

   .. code-block:: python

        class MyAdmin(TreeAdmin):
            list_display = ('title', 'body', 'is_edited', 'timestamp', '_position', '_ref_node_id',)
            form = movenodeform_factory(MyNode)

        admin.site.register(MyNode, MyAdmin)
