Comment:
This isn't really a solution to the problem, or if it is a solution to the
problem then the documentation on QuerySets is wrong. Either way, I don't
believe this is solved.
According to documentation, this it valid:
the_region = TripRegion.objects.all()[0]
guides = DestinationGuide.objects.active().filter(region=the_region)
And sure, it is a valid way to perform a QuerySet lookup, however in order
to make use of say caching which needs to pickle the query set we
shouldn't have to change the QS lookup to:
guides = estinationGuide.objects.active().filter(region__pk=the_region.pk)
