You can add a custom form to the PersonAdmin class and override the __init__() method to dynamically add a ModelChoiceField for selecting the new family of a person.

Try this:


from django import forms
from django.contrib import admin

from .models import Family, Person


class PersonForm(forms.ModelForm):
    new_family = forms.ModelChoiceField(
        queryset=Family.objects.all(),
        required=True,
        label="New Family",
    )

    class Meta:
        model = Person
        fields = ["name", "family", "new_family"]


class PersonAdmin(admin.StackedInline):
    model = Person
    list_display = ("name", "family")
    extra = 0
    form = PersonForm  # Here we Added custom form


class FamilyAdmin(admin.ModelAdmin):
    model = Family
    list_display = ("name",)
    inlines = [PersonAdmin]
    extra = 0


admin.site.register(Family, FamilyAdmin)
