I don't know if this was mentioned earlier, but you might want to check out the OracleStorage product which allows you to use Oracle as storage for the ZODB. http://www.zope.org/Products/OracleStorage This solution would likely scale to your needs. Also there are several object databases like

[Zope-dev] Specialists and __bobo_traverse__

2001-01-16 Thread Roch'e Compaan
I'm still lost as to when __bobo_traverse__ is checked for object traversal and when not. I have very simple piece of SkinScript: WITH SELF COMPUTE __bobo_traverse__ = traversal_method. Looking at the traverse method in BaseRequest.py it looks to me as if an object is always checked if it has

It sounds to me like you're trying to have SkinScript supply a bobo_traverse for the Specialist itself, and this you cannot do. (There are other ways to change a Specialist's bobo_traverse behavior, but SkinScript is not one of them.) The SkinScript you're doing is meaningful only if you want

While that would work for the simple object case, I find the prospect of storing a bunch of BLOBs (for the image data of the Photos) in an RDBMS to be *most* un-appetizing. Storing them on the server's file-system seems in-elegant as well. Okey dokey, just a suggestion. I have heard people

[Zope-dev] ZCatalog with ZClass

2001-01-16 Thread Lily Li
Hello, everyone, It seems that many of you have used ZCatalog pretty well. My problem is that I'd like a ZClass (of a Product) to subclass CatalogAware, and implement all the index and search inside the Product. That means I don't want to do any DTML method stuff outside of the Product.
