In IItem specify "Interface" as the schema. After you defined IUnit you can do 
something like:

IItem.getDescriptionFor('unit').schema = IUnit

[Zope3-dev] How to resolve bi-directionally navigable association?

2005-08-08 Thread Adam Groszer 
Sorry for the crosspost, may I have some expert advice on the
following:

As the subject sais, how can I resolve bi-directionally navigable
association in Z3?
Both objects have to have references of each other, that means that
also the schemas have to have references.

class IItem(interface):
unit = Object(
title=u"Unit",
description=u"Unit",
required = False,
schema=IUnit)

class IUnit(interface):
item = Object(
title=u"Item",
description=u"Item",
required = False,
schema=IItem)

but obviously that does not work, I cannot define one before the
other.
