[google-appengine] Re: QueryIterator Error
The error is on line n.173 that corresponds to a for that scroll a
query object retrieved from memcache or from Entity.all if there isn't
in memcache..
However this is the portion of code:
def tagCloud():
q1=memcache.get("tagCloud")
if q1 is None:
q1=Tag.all()
if not memcache.add("tagCloud",q1):
print "Memcache add error on key \"tagCloud\""
tags=[]
for q in q1:
What can I do?

[google-appengine] Re: How to fix pickling error
I had some problems while I tried storing in memcache a query object obtained with the fuction db.GqlQuery(...) and I've solved my issue with Entity.all() function... The same problem appears when I try to storing in memcache a python list that contains several Object that I've created. I've pybassed the problem but I think that it's good to get you to know this issue. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
