[google-appengine] Re: memcache, What types can it contain?
Hi, For a higher level answer, you can only store things in memcache that are pickle-able. The best way to determine if something is pickle-able is to read the Python docs: http://docs.python.org/library/pickle.html -Marzia On Tue, Mar 24, 2009 at 8:34 PM, Lee Olayvar leeolay...@gmail.com wrote: Odd, thanks for the heads up.

Or is it basically limited to only simple data structures? Because at the moment, i have been unable to store a complex series of class instances into memcache. Resulting in an error involving Can't Pickle cStringIO.StringI. For the full error (mostly): http://dpaste.com/18449/ Any comments would be appreciated, thanks, -- Lee Olayvar -- It is better to be wrong than to be vague. — Freeman Dyson --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
