1. Isn't it enough just to write _.getitem(tid)?
2. A shot in the dark: tmp is not a document, but its rendering. Try
getitem(tid, 0)...

Re: [Zope] PropertyIds
I have a very simple documentclass in very simple structure in method that
should return the properties of the document:
dtml-call "REQUEST.set('tid', REQUEST.cookies['careermanid'])"
dtml-with RESULTS // RESULTS is a ZClass Object Manager
dtml-call "REQUEST.set('tmp', _.getitem(_['tid']))" // tmp is a
document with an id equal to the cookie
dtml-return "tmp.propertyIds"
this line should read:
dtml-var "tmp.propertyIds()"
Two things going wrong:
1. the dtml-return tag is for DTML Methods that should just return
something. You want dtml-var.
2. you call propertyIds in an expression (the line is shorthand for
dtml-var expr="tmp.propertyIds()" - in that case you have to call it
as a function.
/dtml-with
During the application i add properties to the document and want to display
them with the above method. The Property ids does not get shown though.
I've tried:
dtml-with tmp
dtml-var propertyIds
/dtml-with
this should get you a list, like ['title', 'prop1, ...]
and also:
dtml-in "tmp.propertyIds"
dtml-return sequence-item
/dtml-with
this doesn't work for reasons outlined above.

RE: [Zope] PropertyIds
Thanks Rik it works.
I've noticed in some cases that one puts empty brackets at the end of
certain zope object methods. Is that there for methods that can take
parameters?

Re: [Zope] PropertyIds
Thanks Rik it works. I've noticed in some cases that one puts empty brackets at the end of certain zope object methods. Is that there for methods that can take parameters? [rh]Um, not quite, it has to do with the way of calling the object methods in question. DTML has two ways of calling: by name and through expressions. 1. The 'normal' Zope way of writing things is dtml-var objectValues. This is shorthand for dtml-var name="objectValues". 2. The other way is dtml-var "objectValues". This is shorthand for dtml-var expr="objectValues". Everything inside the expression is treated as a python expression. If you call it without the brackets, you're just referencing the method. If you try that in a DTML Method and look in the source of the diplayed document you'll see something like Python Method object at 13fcbf0. If you want to _call_ the method, you'll have to add the brackets (with or without arguments). Hope this is clear.

RE: [Zope] PropertyIds
Very clear, thanks. Really appreciated.
Well i guess the topic was never about propertyids, but i can only tell that
now. Still working with properties i find the following trouble.
dtml-var "MyDoc.propertyItems()" returns a list of key-value pairs
[('Key1','Value1'},('Key2','Value2')]
to access the values of each key sequentially i tried:
dtml-in "MyDoc.propertyItems()"
dtml-let s="_['sequence-item']" key=s[:1] value=[1:]
dtml-var key:dtml-var valuebr
/dtml-in
But this just returns "k" and "ey" resulting in a slice of the keyname.
