30354	Filter not displayed when admin.RelatedOnlyFieldListFilter is used for auth.models.User	rvernica	nobody	"In a model where a field is a foreign keys to `auth.models.User`, `admin.RelatedOnlyFieldListFilter` does not display a filter. Something like:
{{{
class Foo(models.Model):
  bar = models.ForeignKey(auth.models.User, on_delete=models.CASCADE)
}}}
And `ModelAdmin` uses `RelatedOnlyFieldListFilter` for the foreign key:
{{{
class FooAdmin(admin.ModelAdmin):
  list_display = ('bar',)
  list_filter = (('bar', admin.RelatedOnlyFieldListFilter),)
}}}
No filter is displayed in the UI in the right side-bar. No error message is displayed. If `list_filter` is changed to:
{{{
  list_filter = ('bar',)
}}}
It works as expected.
