[Zope3-Users] OOBtrees & ZODB

[Tim Cook]

I am building a platform where I want to initialize the ZODB (that will
be running under Zope) with three folders with sitemanagers.

If I use Folders like this:

if 'AR' not in root['Application']:
    root['Application']['AR']=folder.Folder()
    sm = LocalSiteManager(root['Application']['AR'])
    root['Application']['AR'].setSiteManager(sm)
    transaction.commit()

it works great and I can then add initial objects to the folders.

But, these folder sill potentially contain tens of thousands of objects
so I really want to use BTree Folders.  But when I do this:

from zope.app.container.btree import BTreeContainer

... <lots of other stuff>

if 'AR' not in root['Application']:
    root['Application']['AR']=BTreeContainer()
    sm = LocalSiteManager(root['Application']['AR'])
    root['Application']['AR'].setSiteManager(sm)
    transaction.commit()

I get this:

  File
"/home/tim/projects/ref_impl_python/TRUNK/oship/src/oship/atbldr/atbldr.py", line 78, in ?
    root['Application']['AR'].setSiteManager(sm)
AttributeError: 'BTreeContainer' object has no attribute
'setSiteManager'

So BtreeContainers don't have a siteManager.  

I would like to OOBTree but I have been unable to even discern the
proper way to import it.

Thanks.

Tim
