[Zope] shortcutting the tree tag

[Martin Dougiamas]

Hi John,

The way I do this is to set up an external method containing:

def publicObjects(self):
    "return only public sub-documents and folders"
    result=[]
    for object in self.objectValues(['Folder']):
        if hasattr(object,'hidden') and not object.hidden:
            result.append(object)
    return result

and then make your tree tag use this method with:

<!--#tree branches="publicObjects"-->

    [...]

<!--#/tree-->


Hope that helps,
Martin
