[Zope] dtml-tree with interactive root
Tue, 23 Jul 2002 21:26:56 +0200
(My apologies if You already got this via Zope-forum. I'll avoid
double-posting in the future.)
I want to give the user the following functionality:
1. From some folder deep down the directory tree ("start folder") she/he
may open a tree-view
with the root at this start folder.
2. Interactively, she/he may create tree-views with the root shifted up
by one or more levels up to the root
of the Zope-tree (or wherever the rights allow).
I tried to code this the following way:
In the root folder there is a dtml-method called "show-tree" which does
<a href="<dtml-var absolute_url>"> <dtml-var title_or_id>
This method is called from the "start folder" in essentially the
<dtml-unless uplevel> <dtml-call "REQUEST.set('uplevel' ,
<dtml-call "REQUEST.set('uplevel', _.int(uplevel))">
<dtml-call "REQUEST.set('uplevelp', uplevel+1)">
<a href="<dtml-var URL0>?uplevel=<dtml-var uplevelp>">Up</a>
This works OK.
However, if - after having pushed up the tree-root by some levels - I
want to expand or collapse one of the
branches by using the +/- - icons, the tree is displayed with "start
folder" as root again, instead of the
folder where I tried to expand/collapse the branch. ("expand/collapse
How do I avoid this?
Thanks in advance!
