Comment (by Gordon Wrigley): I would like to do singular prefetches, which seems kinda like what this is asking for. With regard to: {{{#!python User.objects.prefetch_related( Prefetch("groups", queryset=Group.objects.order_by('name')[:1], to_attr="first_group") ) }}} The downside of this is "first_group" is actually a 1 element list. I was imagining maybe it could be just the item when there is a single item slice, or failing that a "flat=True" option on Prefetch. -- Ticket URL: <https://code.djangoproject.com/ticket/34413#comment:10> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
