Unfortunately, Closed ticket #29138 breaks autocomplete for the case of
inherited models. For example, we have the following code:
{{{
# models.py
from django.db import models
class Tag(models.Model):
pass
class Foo(models.Model):
tags = models.ManyToManyField(Tag)
class Bar(Foo):
pass
# admin.py
from django.contrib import admin
from . import models
@admin.register(models.Foo)
class Foo(admin.ModelAdmin):
autocomplete_fields = ('tags',)
@admin.register(models.Bar)
class Bar(admin.ModelAdmin):
autocomplete_fields = ('tags',)
}}}
Now, autocomplete for `admin.Foo` will work but not for `admin.Bar`
because `django.contrib.admin.widgets.AutocompleteMixin.optgroups()`
calculates a wrong value of a variable `to_field_name`, namely `foo_ptr`
instead of `id`, whereupon following look up at
`self.choices.queryset.using(self.db).filter(**{'%s__in' % to_field_name:
selected_choices})` raises an exception because `models.Tag` does not have
`foo_ptr`.
