[Answered ]-Deleting SQL data in associated OneToOneField model from admin

Got it cleaned up and working!

My model:

class Party(models.Model):
    name = models.CharField(max_length=100)
    ...

class Person(models.Model):
    party = models.OneToOneField(Party, editable=False)
    firstName=models.CharField(max_length=60)
    lastName=models.CharField(max_length=60)

    def delete(self):
        d = self.party.id
        Party.objects.get(id__exact=d).delete()

My admin:

class PersonAdmin(admin.ModelAdmin):
    actions=['really_delete_selected']

    def get_actions(self, request):
        actions = super(PersonAdmin, self).get_actions(request)
        del actions['delete_selected']
        return actions

    def really_delete_selected(self, request, queryset):
        for obj in queryset:
            obj.delete()

        if queryset.count() == 1:
            message_bit = "1 person was"
        else:
            message_bit = "%s people were" % queryset.count()

        self.message_user(request, "%s successfully deleted." % message_bit)
        really_delete_selected.short_description = "Delete selected entries"
        ...
