[Zope] Mother, tell your children not to walk my way ;-) was: Running up and down the hierarchy

[Danny William Adair]

Hi Bill,

You are totally right, but that only affects the top node. The deeper the
object I'm looking for is down this path, I still need the withs:

(I didn't mean Zope's root folder with 'the_root', just any node that A and
B are contained in. Was a stupid name, actually.)

mother------A-----Aa
               ---Ab------Aba------Abaa------Abaaa(image)
      ------B-----Ba
               ---Bb------Bba
                       ---Bbb(DTML document)

Every step further, one more with statement. Furthermore, if I eventually
have another "A" folder on my way up, the bus driver taking me 'with' him
will let me off too early:

mother------A-----Aa
               ---Ab------Aba------Abaa------Abaaa(image)
      ------B-----Ba
               ---A-------Bba
                       ---Bbb(DTML document)

But I've solved the issue.
I've just created a Python Script 'goto' taking one parameter 'path',
consisting of this single line:

return context.restrictedTraverse(path)

I've put it in the root folder to have it available everywhere and now can
do both of these in DTML(using the 2nd example of this mail):

<dtml-var "goto('A/B/mother/A/Ab/Aba/Abaa/Abaaa')">

<dtml-with "goto('A/B/mother/A/Ab/Aba/Abaa')">
  <dtml-var Abaaa>
</dtml-with>

I could let the path start with a '/' to start the whole marathon from
Zope's root folder, but then again I would need the permission to go
_through_ there (other with unrestrictedTraverse, I guess)

Thank you anyway,
and...thx for the membership product ;-)
Danny
