hi

i would like to cache the results of method in a view, and thougt, that RAMCache
could be of use here.

After spending a lot of time searching for some documentation or examples, i
came to this:

from zope.app.cache.ram import RAMCache
cache = RAMCache()
query = cache.query('test',key={'x':1})
if query == None:
        result = expensive_stuff_method()
        cache.set(result, 'test', key={'x':1})
        return result
else:
        return query

but that won´t work, the cache looses it´s entry, if i call the browser-view again.

any hints?
thanks, Dominique

for a direct usage of ramcache (not as utility) you can instantiate one in your module, as an example see

http://svn.zope.org/z3c.image/trunk/src/z3c/image/proc/adapter.py? rev=76889&view=auto

(forget about the ulimit stuff there)

note that if you have zeo with multiple zope instances the cache is not shared across instances, if you have such a setop, a good option is lovely.memcached

http://svn.zope.org/lovely.memcached/trunk/

distributions are on http://download.zope.org/distribution/

regards, bernd
