AttributeError in python script
##parameters=myFolder, myObjectType results=[] for object in container.myFolder.objectValues(myObjectType): tuple = object.title, object.id results.append(tuple) return results I get an attribute error calling the following. tuple_of_items('idofTargetFolder','DTML_Method') I have tried getitem and render. Please help me with what I have missed? Thanks, Trevor

##parameters=myFolder, myObjectType results=[] for object in container.myFolder.objectValues(myObjectType): getattr(container,myFolder)
This is called "Computed Attribute Access". You (and others) use it whenever an attribute it either not constant or not a (Python) name... More info in <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html> Dieter

The following line tests properly in the script. for object in context[myFolder].objectValues(myObjectType) <<tests correctly It looks like this is an alternative to your suggestion. The continuing issue is...now I am trying to call this tuple for a Formulator Items property override. I include the following for Items and get an AttributeError tuple_of_items(emailscripts,'DTML Method') My assumption is - emailscripts is an object - and DTML Method is a string when processed in the script. But I must still be calling it incorrectly. Maybe Formulator can't populate Items with objects, so I need to convert the id to strings? But I thought the advantage of Formulator was to use objects for use in HTML forms. Thanks for the help. Trevor

It is when "context" is a folder... The difference, subscription does not use acquisition in this case, while "getattr" does.

Look careful at your error message! It should tell you, what attribute is not found.
My assumption is - emailscripts is an object If it is indeed, then you must not use subscription nor "getattr". Use the object directly (at least, if it is the correct one).
- and DTML Method is a string That should not be a problem.
