So, i'm reading zope3 web component architecture book (quite cool by the
way) and since i'm too SQL DB oriented I was wondering how to garantee
fields uniqueness in ZODB.
For instance, if I have a IMachine interface, I want the ip_address
field to be unique across all machine objects.
Is that something I have to tie in the validation routine of ip_address?
Other options?
