Take a look at the portable hole stuff at http://www.zope.org/Members/TheJester ----- Original Message ----- From: "Joe Graham" <joe@aiobjects.com> To: <zope@zope.org> Sent: Saturday, February 09, 2002 1:50 AM Subject: RE: [Zope] Zope symbolic links

Okay well what I had in mind was something like this: I have a folder to represent website "a" and another folder to represent website "b". i have another folder with some useful scripts and yet another folder with some useful graphics / html and it would be nice for the sake of tying things together with vhost_monster and apache to create a "virtual" folder inside website "a" and website "b" folder. exampe: /[root_folder] +/porn_layout_engine +/lots_of_nice_pics_in_sequence +/entertainment_site_a +/->porn_layout_engine +/->lots_of_nice_pics_in_sequence +/entertainment_site_b +/->porn_layout_engine +/->lots_of_nice_pics_in_sequence

So it would seem that response.redirect() in the case of the ZMI would work, but it's not really what I am after. I am just hoping to "external" folders as if it existed in the child folder. I could use restricted traverse but maybe there is a way to approach this issue in a uniform fashion? Maybe a Zope product that does restricted traverse and can "mimic" the type it points to. If someone can give me some pointers on how to approach this then I would not mind giving it a try. Okay so you see my dilema? Well if not at least hopefully the problem domain (although fictional) is a little more interesting. :)

Quite easily and simple, actually. Here's my take on it (from a previous message on the list. C U! -- Mario Valente At 19:04 07-08-2001 +0100, Mario Valente wrote:

Hi:

OK everyone, I've managed to get object links to work.

As discussed previously by others (re: object references) and asked by myself: I had the need to be able to refer to objects from different points of the folder hierarchy without duplicating those objects.

Yes I know that can be done *programatically*. That is not the idea.

The idea is to have a folder with differente widgets/components and to be able to copy and paste references to those widgets throughout the folder hierarchy. Of course that the usual copy/paste is not OK, since that *duplicates* the objects and as such further changes to the original object wont be reflected in the copies.

With something like this + Ordered Folders you are able to have an index_html that just renders the objects within a folder and you can then drop objects/widgets into the folder to produce a page.

What I did:

- edited CopySupport.py - copied the manage_pasteObjects method to a manage_pasteMonikers method - commented the #ob=ob._getCopy(self) line (the duplicate object part) - added a "Paste Ref" button to the lib/python/OFS/dtml/main.dtml file that calls the pasteMonikers method

""" <input class="form-element" type="submit"

name="manage_pasteMonikers:method"

value="Paste Ref." /> """

It works. It does what I want/need. When you change a reference, the original also changes. When you change the original, the references change. You can delete either the reference or the original and all is OK.

Issues/TODO

- find a way to distinguish references from the original (tried to change the meta_type at paste time but no luck). At least the meta_type/icon should change to provide a visual cue. - provide tool(s) to find impact of changing a reference. Provide a link from a reference object to the original. Provide a link from an object to its several references.

Comments and experiences are welcome.
