Description
I am getting an error while trying this code. I am using memcached as my backend. It looks like it isn't able to correctly pickle the queryset. This article makes me think it should be able to pickle them... http://docs.djangoproject.com/en/dev/ref/models/querysets/#pickling-querysets
places = Place.objects.all()
cache.set("places", pickle.dumps(places))
c = cache.get("places")
pickle.loads(c)
Traceback (most recent call last):
File "<console>", line 1, in <module>
