Django — How to Order Inline ForeignKey

To apply ordering to a foreign key in the admin, you simply define an “ordering” attribute in your ModelAdmin.

But what about Inlines?

To apply ordering to an Inline Model’s foreign key, override the default form of the admin.StackedInline or admin.TabularInline subclass by specifying a ModelForm.

class OrderedInlineForm(forms.ModelForm):
    product = forms.ModelChoiceField(queryset=Product.objects.order_by('name'))
    class Meta:
        model = MyInlineModel

class MyInlineModelAdmin(admin.StackedInline):
    model = MyInlineModel
    form = OrderedInlineForm
