What!? Does people actually WANT that? I thought that was just an
effect of either crappy programming or stupid programmers. :)


Can you explain an approach to accomplish something similar in zope3.


As long as you also make it possible to access each article with just
/blog/article, I'll be happy. :)

 I have looked at it and thought it would be a nice package to finish
 however I haven't yet got how to perform the nice traversal tricks for
 nice urls for entries (I had written to the five list in July). Any
 pointers or an explanation would be appreciated. From my post to five list:

Null problemo with z3c.traverser. :-)

Seriously, the pluggable traverser and the plugins are the way to go. We use 
them for the lovely package heavily to do logic paths.

Hi Stephan. Yes, I have seen this added recently with great interest.

:-) I'm hoping to experiment with this shortly to see how this works.

Can you point to any code using this at the moment that I may see a
practical demonstration of its integration. Many thanks.


Here is the basic idea:

  !-- Make IBlog traversing pluggable for browser access only --
  view
  for=.interfaces.IBlog
  type=zope.publisher.interfaces.browser.IBrowserRequest
  provides=zope.publisher.interfaces.browser.IBrowserPublisher
  factory=z3c.traverser.browser.PluggableBrowserTraverser
  permission=zope.Public
  /

  !-- Make sure container item traversal is available for all containers --
  subscriber
  for=zope.app.container.interfaces.IReadContainer
   zope.publisher.interfaces.browser.IBrowserRequest
  provides=z3c.traverser.interfaces.ITraverserPlugin
  factory=z3c.traverser.traverser.ContainerTraverserPlugin
  /

  !-- A plugin that traverses all years --
  subscriber
  for=.interfaces.IBlog
   zope.publisher.interfaces.browser.IBrowserRequest
  provides=z3c.traverser.interfaces.ITraverserPlugin
  factory=.blog.YearTraverser
  /

In Python something like that:

import zope.interface
from zope.location import location
from zope.publisher.interfaces import NotFound
from z3c.traverser import interfaces

class YearTraverser(object):
zope.interface.implements(interfaces.ITraverserPlugin)

def __init__(self, context, request):
self.context = context
self.request = request

def publishTraverse(self, request, name):
yearNumber = int(name)
if yearNumber  2000:
raise NotFound(name)
year = YearProxy()
location.locate(year, self.context, name)
return tag

Stephan
