-------------------------+---------------------------------
I believe the way the random filter works right now is asinine or at least
not very useful.
When working in templates, 90% of the lists we have to deal with are
QuerySet instances, so for this filter to choke when we pass it an object
list is not very helpful.
I've seen [https://code.djangoproject.com/ticket/8044 a proposed patch]
for this posted three years ago, but it was rejected on the ground that it
required a new db hit and thus was problematic for large querysets. Fair
enough.
My patch use the queryset.order_by('?') method so it (theoretically)
doesn't require a new database hit.
It also introduce a new "shuffle" filter, which useful when you want to
randomize a list or a queryset instead of just picking one randomly.
