Please refer to the CI build linked above for the currently supported combinations of Python and Django.

Installation

pip install django-admin-ordering, and add admin_ordering to INSTALLED_APPS.

Usage

First, you need a model ordered by an integer field. If you are happy with a model where 1. the ordering field is called ordering and 2. the ordering field is automatically initialized so that new objects are ordered last you can also inherit the abstract admin_ordering.models.OrderableModel model. If you define your own class Meta you should inherit OrderableModel.Meta so that the ordering attribute is set to the correct value:

.. code-block:: python

from admin_ordering.models import OrderableModel

class MyModel(OrderableModel):
    # ...

    class Meta(OrderableModel):
        # ...

Orderable change lists

.. code-block:: python

    from admin_ordering.admin import OrderableAdmin

    @admin.register(MyModel)
    class MyModelAdmin(OrderableAdmin, admin.ModelAdmin):
        # The field used for ordering. Prepend a minus for reverse
        # ordering: "-order"
        ordering_field = "order"

        # You may optionally hide the ordering field in the changelist:
        # ordering_field_hide_input = False

        # The ordering field must be included both in list_display and
        # list_editable:
        list_display = ["name", "order"]
        list_editable = ["order"]


Orderable inlines
~~~~~~~~~~~~~~~~~

.. code-block:: python

    from admin_ordering.admin import OrderableAdmin

    class MyModelTabularInline(OrderableAdmin, admin.TabularInline):
        model = MyModel

        # Same as above; "-order" is also allowed here:
        ordering_field = "order"
        # ordering_field_hide_input = False

``OrderableAdmin`` comes with a default of ``extra = 0`` (no extra
empty inlines shown by default). It is strongly recommended to leave the
changed default as-is, because otherwise you'll end up with invalid
inlines just because you wanted to change the ordering.


Limitations
===========

- Starting with Django 1.9 newly created inlines are automatically
  assigned a good ordering value. Earlier versions do not support the
  required ``formset:added`` signal.
- ``OrderableAdmin`` can be used both for inlines and parents, but this
  also means that you cannot register a model directly with
  ``OrderableAdmin``.
- Using django-admin-ordering with filtered or paginated lists may
  produce unexpected results. The recommendation right now is to set
  `list_per_page` to a bigger value and not reordering filtered
  changelists.
- Note that django-admin-ordering assigns ordering values in increments
  of 10, emphasizing that the ordering value should not have any
  significance apart from giving relative ordering to elements.
