Inspired by this proposal by Johannes Dollinger:
[https://groups.google.com/forum/?hl=en#!topic/django-
developers/lH5UhciGTBw], this quick (untested!) patch allows to use
{{{
is_blue = Q(color='blue')
Owner.objects.filter(thing=is_blue)
}}}
as a better alternative to:
{{{
Owner.objects.filter(thing__in=Thing.objects.filter(is_blue))
}}}
being better because it generates the same query as:
{{{
Owner.objects.filter(thing__color='blue')
}}}
