@ -800,6 +800,27 @@ filter, if your data is in a list of dictionaries::
{% regroup people|dictsort:"gender" by gender as gender_list %}
Grouping on other properties
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Any valid template lookup is a legal grouping attribute for the regroup
tag, including methods, attributes, dictionary keys and list items. For
example, if the "gender" field is a foreign key to a class with
an attribute "description," you could use::
{% regroup people by gender.description as gender_list %}
Or, if ``gender`` is a field with ``choices``, it will have a
:meth:`~django.db.models.Model.get_FOO_display` method available as an
attribute, allowing you to group on the display string rather than the
``choices`` key::
{% regroup people by get_gender_display as gender_list %}
``{{ gender.grouper }}`` will now display the value fields from the
``choices`` set rather than the keys.
