[Zope3-Users] Absolute url of an object

[Paulus Zegwaard]

Hi,

OK, thanks to Alen and with some further digging, I can sort of 
answering my own question, I found some answers here:
zope3-for-zope2-developers.pdf from Phillip von Weitershausen. Thanks
Phillip for thinking of these legions of "poor old fashioned" zopistas! ;-)

So for the other newbies out there (if they search the archives later):

    * from Python do this: zapi.getView(obj, 'absolute_url', request) #
      obviously import zapi first
    * from a page template: obj/@@absolute_url

Also without doing any extra, it seems that objects don't know their
name anymore. No getId() or title_or_id().
But as Alen pointed out the parent normally does some magic, so:
you have __name__  (id in Zope 2 speak)
and __parent__ (is obj.getParent() in Zope 2)

Mmm, I guess I'm gonna roll my own ordered containers and pages that
have a title attribute.

Cheers,

Paulus
