Django: list_filter and foreign key fields

Question

Django doesn\'t support getting foreign key values from list_display or list_filter (e.g foo__bar). I know you can create a module method as a workaround for list_display, but h

Well, the docs say that you can may use ForeignKey field types in list_filter:

http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter

An example:

# models.py:
class Foo(models.Model):
    name = models.CharField(max_length=255)

    def __unicode__(self):
        return self.name

class Bar(models.Model):
    name = models.CharField(max_length=255)
    foo = models.ForeignKey(Foo)

# admin.py:
class BarAdmin(admin.ModelAdmin):
    list_filter = ('foo')

If you want to filter by a field from the related model, there's a patch on the way to make this work (will probably be merged into 1.2 as it seems):
