[Zope] Zope and Paths

[Peter Bengtsson]

If you're a python product developer, you write a method called::

  def __before_publishing_traverse__(self, object, request):

In self.REQUEST you'll find REQUEST['TraversalRequestNameStack'] which 
is a list of the bits of the URL. I.e. something like ['Articles', 
'32042'] depending on your situation.

This list you can modify on the fly to suit your needs.

For example, what I do is this:
Someone enters http://www.peterbe.com/oc-Zope
I get a list like ['oc-Zope']
If I in this list finds something that starts with 'oc-' I pop it from 
REQUEST['TraversalRequestNameStack'] and deal with it separately kind of 
like this:

REQUEST.set('onlycategory', 'Zope')

Then in some other part of the site I look for the REQUEST key 
'onlycategory'.


For the creation of these URLs, I suggest that you wrap all URL 
references through some function.

For example, what was:

  <a href="ViewArticle?id=32042">

you now do:

  <a href="<dtml-var "myURLFixer('ViewArticle' articleid=32042)">">


Another example (warning! extremely slow server), is
http://home.peterbe.com/issuetrackers/newT/ListIssues/start-10/sortorder-urgency/reverse-1
which I think looks better than
http://home.peterbe.com/issuetrackers/newT/ListIssues?start=10&sortorder=urgency&reverse=1


Use your imagination.



On a side note, look at this URL:
http://store.doverpublications.com/by-subject-science-and-mathematics-mathematics-fourier-analysis.html
(not Zope but a nice use of this possibility)
