Thanks Tom, Your answer also clears up my last question. Zope appears to have a few wrinkles around the edge which the newbie need to get used to. Nevertheless, it seems to be an excellent platform overall, well worth the initial pain! Cheers, Dave. On Monday 13 August 2001 17:19, Thomas B. Passin wrote:
In Python, an expressions like "obj.id" would normally return the value of the "id" attribute of the "obj" object. However in Zope, sometimes objects have a ***method*** called "id()". On such an object, asking for "obj.id" returns the function object (a method is a function attached to an object), rather than the value you would get by using the function to compute something.
How can you tell whether an object uses an id attribute or an id() method? Not easily, so use the getId() method instead. Then you won't have to know which is which.
Maybe it would have been better if Zope hadn't done it this way, but that's how it is.

I am a newbie to Zoip and apologize if this is a trivial question, but it has been giving me grief for several hours now. I have found by experimentation that when iterating through a set of objects and testing their ids that the following only seems to work ONLY for folders:
<dtml-if "id == 'theObjectIdString'> .... </dtml-if>
If however I use the code:
<dtml-if "getId() == 'theObjectIdString'> ... </dtml-if>
all seems to work correctly. Obviously I am missing something very basic here.
