list_filter not working with foreign keys

[Tom Carrick]

From what I understand reading the docs, this should work, where author is a foreign key:

list_filter = ["author"]

But it silently fails, it just doesn't show on the page. However, if I specify the field, it works fine:

list_filter = ["author__name"]

Thanks for the report, however it works for me.

This is definitely an issue. I think I've narrowed it down somewhat: the filter actually works, i.e. you can set the querystring manually and it filters correctly, but it doesn't show up on the admin change list page.

I think it's because the primary key of the related model is a CIEmailField, but I'm not sure, it's tricky to debug as there's no output.

It works for me also with a ForeignKey to model with CIEmailField as a primary key, e.g.

class Author(models.Model):
    email = CIEmailField(primary_key=True)

Please provide a sample project that reproduces this issue.
