Following this advise I’m trying to do a nested get\_cache.

[http://lists.danga.com/pipermail/memcached/2007-July/004581.html](http://lists.danga.com/pipermail/memcached/2007-July/004581.html)

Forum.get\_cache(185).users works fine and gives me back a list of users  
however these users don’t have the associations I’m looking for so I’d  
like to do another lookup like this

User.get\_cache(Forum.get\_cache(185).users) or  
User.get\_caches(Forum.get\_cache(185).users)

When I look at the query however this is what I see

…WHERE (`users`.`id` IN (0,0,0,0,0,0,0,0,0))

Do I need to do some type of flatten ?

Help please!
