I have some data that will not naturally live as an item in a folder. If I'm using Zope, how do I establish a root for it? The ZODB docs talk about how to handle a free-standing database, but I don't see info about how to use the one that Zope has already set up. I recall there's some way to get a handle to the open database, but I don't recall exactly what. Can anybody help me out? If I use a class variable, will that be persisted automatically, e.g. class MyManager(Persistence.Persistent): MyClassVariable = SomePersistentClass() ..... ? (Actually, I'm not sure if it matters whether MyManager is a subclass of Persistent). Or, if it is not automatically persistent, is there anything I can do to make it persistent so that it will obey the transaction boundaries coming from web requests? Final question, which is distinct from the root objects issue: if I use Zope's Persistent List, will that avoid the problem of faulting in the whole list if I don't need it? I am looking for a good way to keep a record of transactions. ZODB's raw transaction recording is probably not quite right since it has the wrong granularity, it mixes a lot of unrelated transactions (it's only some I want), and I think it can get zapped if I do various database compactions and cleanups. Thanks.
