Re: In the Admin, Is it possible to make filters on foreign keys usable with lots of related objects?

I've used that in a few admin pages, as far a I understand it just restricts the allowed values for a model's foreignkey field when editing a model instance. I don't see any way to use that to change how the `list_filter` functions -- am I missing something?

Thanks,
Paul

Currently it's simple to configure a filter on a foreign key in the admin:

`list_filter = ['theforeignkeyfield']`

However in practice this is barely usable in most cases that I've encountered, since the admin uses RelatedFieldListFilter, which fetches the full list of objects from the DB and loads them into the browser. For any production site that either times out or makes the admin unusably slow, not to mention the UX is terrible as it inserts a list of all of the items into the filter bar that needs to be scrolled through.

I'm not sure if this is fixed in 2.0 (I haven't played with the new select2 integration that was added), but is there a plugin / workaround to use something like django-autocomplete-light, or a `raw_id_field` type approach in pre-2.0?

Have you looked at  ...
