Hi all, I have a schema that defines a tuple field that holds object field of a specific type. Now I want to be able to traverse each object in the tuple by using ./<field_name>/<index>.
From the Zope3 book I've learn how to create a Traverser (by subclassing the ContainerTraverser) but my problem is that the first name
encountered is the field_name, but I can't return the tuple (or) because it's a simple object not aware of location (that would be fixable I guess, I've seen a LocationProxy somewhere). Instead I return the context, which has the effect that the Traverser gets called again (with the index), but I can't figure out how to save the state, that the <field_name> has already been traverser, so I'd know that the index should be look up on the field_name. Are there anyway to know which part of the URL that has been traverse, or to traverse ahead in the first call to the Traverser? Any advice on this problem? (I just realized that using a volatile attribute on the context might work, but it just feels to darn un-zope3-ish) -- Johan Carlsson Tel: + 46 8 31 24 94 Colliberty Mob: + 46 70 558 25 24 Torsgatan 72 Email: [EMAIL PROTECTED] SE-113 37 STOCKHOLM _______________________________________________ Zope3-users mailing list [email protected] http://mail.zope.org/mailman/listinfo/zope3-users
