[Zope] get objects DTML Document having Property order...

2000-05-30 Thread QUIN Frédéric 

Hello,


I want to do :
dtml-in "objectValues('DTML Document')" sort=order
...
/dtml-in

I have some DTML Documents which don't have the property "order", and I
don't want to consider those documents in my loop. But if I put the
"sort=order" option, Zope raises an error

How can I do ???


Thanks a lot,
Frederic

Here's a convoluted hack (untested).  I wonder if anyone can come up
with a better way.

dtml-let values="objectValues('DTML Document')" filtered="[]"
  dtml-in values
dtml-if order
  dtml-call "filtered.append(_['sequence-item'])"
/dtml-if
  /dtml-in
  dtml-in filtered sort=order
... your code here ...
  /dtml-in
/dtml-let

... but the version of Zope in the CVS repository already has a change
that makes it so the sorting code will consider fields that don't exist
to have the value "None".  This makes it so you can sort the natural
way.
