Hello :)
I'd like to do something like this:
def load_chapter(book, chapter):
args = ('Alice', 3)
a = cache.ram('%s_%s' % args, load_chapter, arguments=args,

where the cache would execute load_chapter('Alice', 3) if necessary.
Any advices, please?

Hi Massimo,
i touched it to cache function instead of constructor:
class Blah:
def sessiontime(self):
return session.ctime
def cache_test():
import time
session.ctime = time.ctime()
def blah():
return Blah()
b = cache.ram('blah',blah,30)
return
I tried to move the part which asks session for the ctime value into a
model:
def sestime():
return session.ctime
In controller there is:
class Blah:
def sessiontime(self):
return sestime()
def cache_test():
import time
session.ctime = time.ctime()
def blah():
I played with the cache more. If I pass current session to the object
loaded from cache, it works OK, I mean the times returned are equal:
class Blah:
def sessiontime(self, session):
globals()['session'] = session
return session.ctime
def cache_test():
import time
Hmm.. I had to cut my objects into parts, those which hold data are
being cached while those with logic are not... kind of hack, but I'm
no more directly affected by the bug.

I'm aggresively caching nearly everything.. it helped to reduce
