Subject: Re: Querysets: returning a single item with the greatest id.

Does latest()[0] work exactly as the original poster was looking for?
latest() works based on a date field, not the pk field (which *could*
return a result different than expected).
Tom's approach, explicitly ordering by pk, would work exactly as
desired.

@Tom, thanks. I thought of ordering the QuerySet, but I was not sure whether
that would default to ASC or DESC - and I was not sure how to pass
parameters to influence this.
@Mike, thanks. That looks simpler to do.

Hi everyone,
How would one fetch a single item with the largest id (or most recent date
of creation) via the database API?
