[Zope-dev] Computed fields in ZCatalog

[Kevin Dangoor]

Hi,

    Looking at the ZCatalog code, if an index or metadata field is callable
for a particular object, then that function will be called. However, it
isn't called with *any* parameters. Is there any way to make that metadata
value based upon other values in the object?

    For example, if I wanted to create a method that would return
Property1+Property2 and have that value show up in the Catalog, can that be
done?
