Re: [Zope] objectValues Question

[Rik Hoekstra]

I'm new to Zope and while 'playing' around I wondered about the following:

I've created a DTML method (called MyListFiles) that lists the 'File'
objects contained in a folder:

Now when I create a DTML document and call this method like this:



it produces no output.


Because DTML Documents are object of their own and DTML Methods are not.
THis means that if you are trying to get the 'objectValues' from the DTML
Method it will get them from the containing object, a Folder. If you try to
get them from a DTML Document, it will not return anything, as the DTML
Document holds no other objects. The solutions is to make the DTML Method
call its parent's (=containing object) objectValues. For example (untested):

By applying your MyListFiles method within the context of your DTML Document
you are asking for files that are contained by your DTML Document and there
are none. By 'viewing' your method in the management interface you are
applying your method within the context of the folder that contains it, and
that folder apparently contains file's. If you want to use your method
within a DTML Document with the very same result you could use for instance:
