[thelist] Zope - top level folder listing cont...

Memo from Martin P Burns of PricewaterhouseCoopers

-------------------- Start of message text --------------------

In part answering my own question, but

   <dtml-in expr="PARENTS[-1].objectValues('Folder')">
worked... up to a point.

See, the fun thing is that not all of my subfolders are content folders -
some have images, some resources and some are just plain temporary
scaffolding.

So I did what I thought would be a sensible thing, set a flag on content
folders, and conditionalise like so:

<dtml-in expr="PARENTS[-1].objectValues('Folder')">
    <dtml-if isContentFolder>
     ....write out links
    </dtml-if>
</dtml-in>

But while the above works fine for
http//www.mydomain.com/foo.html
once you get into sub-directories:
http//www.mydomain.com/bar/foo.html
it all goes pearshaped as the conditionalisation doesn't work.

For some reason, the method seems to think that *all* the top-level folder
objects have this property when called from an object which has it.

Cheers
Martin


Subject:    [thelist] Zope - top level folder listing

Hi there

I'm trying to get a consistent nav to the top-level sections in my site
using Zope, with the basic idea of pulling back a list of the folders and
outputting them with links.

Simple, eh? I thought so, with a simple iteration through the top level
object along the lines of
  <dtml-in expr="rootObject.objectValues('Folder')">

My problem seems to be getting an object reference to that root object
which works at all depths of the site, as
  <dtml-in expr="aq_parent.objectValues('Folder')">
and similar only work 1 level down in the site.

Any suggestions?
Probably something which would get me the length of the PARENTS sequence
would do it, as I could then probably do
  <dtml-in expr="PARENTS[foo].objectValues('Folder')">

I'm sure the information is all there in the Zope book, but while it's a
great quick reference, it's really, really light on examples.
