Re: [Zope] dtml-tree and leaves

30 Apr 2002

      Hi Dieter,                                                            

Thank you for this help. In fact, I did what you told me. I rename    
my dtcTemplate.I was waiting for a better a way.                      

But you're right. I wanted to let the name to be the same, only the   
place in the hierarchy should be different.                           

But, as you said, there is no leaves_expr.                            

Maybe it will be necessary  to do one, in the future.                 

Kindly                                                                
PS

I want to use of dtml-tree to get what there is in a folder and

subfolders, with a method pass in leaves.

For this I've this architecture :
...
...
...
...
!-Root
...
...
!-------+Folder A
...
...
!-----------+Folder B
...
...
!-----------+Folder C
...
...
!-------+Folder D
...
...
!-----------+Folder E
...
...
!-----------------index
...
...
!-----------------dtcontent
...
...
!-----------------dtcTemplate
...
...
!----index
...
...
!----dtcontent
...
...
!----dtcTemplate
...
...
...
...
When I try to do
...
...
...
...
Root/Folder D/FolderE/index, with code in index as :
...
...
...
...
<dtml-tree PARENTS[-1].Folder A  branches="objectValues"
...
...
leaves="dtcTemplate">
...
...
...
...
I got the content with the template of Root/dtcTemplate.
...
...
So, How can I write to tell to leaves to get the dtcTemplate in
...
...
Folder E ?
...
The "leaves" method is resolved relative to the currently           
rendered                                                              
tree item. This means for items outside "E" you will get            
"/dtcTemplate".
I am not sure, whether there is a "leaves_expr" attribute           
(I do not think so). It might help you.
An sure work around would be to rename one of your                  
"dtcTemplates".                                                       
But, probably, you have a reason that the are named equally...
