Orderable change lists and inlines done right^Wsimple

Project description

https://travis-ci.org/matthiask/django-admin-ordering.svg?branch=master

Please refer to the Travis 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.

Orderable change lists

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

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 workaround right now is to set list_per_page to a bigger value and not reordering filtered changelists.
