[Zope] Accessing CURRENT property

[Alex Renier]

Hello,
if I have a folder1 in a folder2 and my folder 1 has a
certain property.  If I want to know if folder2 has
the property I use hasattr() method on folder2, but it
returns true because it looks down the hierarchy and
sees the property in folder1.  is there a way to check
for the property in folder2 ONLY without checking the
ancestor folders?.

Thanks!

[Zope] DTML-tree Custom sort

[Alex Renier]

Hello,
I am trying to do a custom sort.  I am using:
dtml-tree branches_expr=objectValues(['Folder'])
sort=orderInt skip_unauthorized

orderInt is an integer property of some folders.  I
would like the dtml-tree tag to look up the property
of the current folder and sort based on the integer
value, but if the property does not exist I would like
it to be excluded from the tree.  Is there a way to do
it? 

Thanks for any help!

Thanks for your help AJ
I get this:

Error Type: SyntaxError
Error Value: invalid syntax (line 1)

dtml-tree branches_expr=[o for o in
objectValues(['Folder'] if hasattr('orderInt'))]
sort=orderInt skip_unauthorized

It doesn't like how I put spaces in objectValues()
attributes for  if hasattr...
Is the syntax a bit different?
Thanks!

 perhaps

 objectValues(['Folder'] if 
 hasattr('orderInt')])
 sort=orderInt skip_unauthorized

Great thank you both!!!
I never knew you could do if-statements like that.

 I think that Andreas meant
 
 dtml-tree branches_expr=[o for o in
 objectValues(['Folder']) if 
 hasattr(o,'orderInt')] sort=orderInt
 skip_unauthorized
