There is a nice little idiom in Django for testing whether any result set
corresponds to a QuerySet: {{{ qs.extra(select={'a':
1}).values('a').order_by() }}} . This is used in at least 2 places within
Django. It's a very nice idiom and it should be a method on a QuerySet
because otherwise every time you use it you have to write a comment
explaining what the hell you're doing.
