#24004 closed Bug

Can't use only() with latest() if x is in only() and get_latest_by — at Version 1

Description (last modified by Tom Carrick)

model Page(models.Model):
    ...
    last_modified = models.Datefield()

    class Meta:
        get_latest_by = 'last_modified'

Suppose I want to get the date of the last modification, I might do something like this:

Page.objects.only('last_modified').latest()

But on trying it, we seem to get stuck copying something until we reach maximum recursion depth.

I don't know if this is a bug or if it's simply not going to work, but if it's the latter, I think it could be documented somewhere.
