Django — Ordering Admin / ModelAdmin Inlines

Ordering admin inlines is a common problem with a not so documented fix that I created. Even the BaseInlineFormSet.get_queryset() isn’t documented. By the way, it’s ever so slightly confusing that managers use `get_query_set` and this uses `get_queryset`.

To order admin inlines, specify the FormSet used by the Inline and override get_queryset() in your formset definition with ordering.

from django.forms.models import BaseInlineFormSet

class OrderedFormSet(BaseInlineFormSet):
    def get_queryset(self):
        return super(OrderedFormset, self).get_queryset().order_by('-sortfield')

class MyInline(admin.TabularInline):
    model = Item
    formset = OrderedFormSet
