new to zope: security question
by Paul Worona 23 Feb '02

23 Feb '02

I am new to Zope and trying to set up a role that restricts access to certain object types. I was able to set up the desired security, but, but when I tried to restrict access to particular documents that the role still had access to, the role was no longer able to access the management screens. Furthermore, I have not been able to reset this security setting. Specifically, when I restricted access to the management screen for the index_html at the root level, the role was blocked not only from root level management screens, but from all sub folder management screens as well. Resetting the security to the index_html file has not solved the problem. I have searched the Zope web site for more information, but havent been able to find anything pertaining to this. Does anyone have any thoughts on what I might be missing? Any help would be appreciated. -Paul -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Paul Worona Assistant Director for Systems Health Sciences Library System University of Pittsburgh 200 Scaife Hall Pittsburgh PA, 15261 Phone: 412/648-8942 Fax: 412/648-9020 Email: worona(a)pitt.edu ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

ZCatalog help
by Keith Alperin 23 Feb '02

23 Feb '02

Greetings Zopistas! I'm currently working on a site which requires that I store City, State and Country entries in a hierarchy such that multiple cities can roll up under a state and multiple states can roll up under a country. To accomplish this, I have a created a small python product called LocationManager which stores data as follows: USA Massachusetts Boston Lexington Concord Illinois Chicago Evanston California Los Angeles San Diego Canada Quebec Montreal etc What i would like to do is use a Catalog to flatten that data out and enable me to retrieve all of the cities in one fell swoop. I've read over the ZCatalog tutorial and have searched zope.org, and I think I see how to catalog properties of products. However, I haven't really found anything that describes: a) How to build a python product that is catalog aware? b) How do i retrieve the data from the catalog without a search interface? URLs to any resources, or any answers to my questions would be MOST appreciated. Thanks so much, Keith R. Alperin

Re: [Zope] Question about accessing properties of images

I anxiously await your reply! I imported your image, created the following DTML Method <dtml-var standard_html_header> <h2><dtml-var title_or_id> <dtml-var document_title></h2> <p> <dtml-var expr="_.getitem('01').desc"> </p> <dtml-var standard_html_footer> and viewed it. Of course, I saw the description. I can see 2 potential problems causing your failure: 1. Your image's name is valid in URL's and DTML but not in Python expressions (where you are inside "..."). Inside Python, "01" is not an object but the integer 1 (the leading "0" is intepreted as "octal number"). Integers do not have attributes. The "_.getitem" above accepts arbitrary names and looks them up transparently in the DTML namespace. (read the "Name lookup section" in <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html> when your want to learn more about namespaces and lookup). 2. Where you use "pic.desc", there may be "dtml-with" active (to facilitate access to the "largspics"). In this case, your "pic" may be the large image, not the thumbnail. In this case, you would probably use a nested "dtml-with" to access your thumbnail. I expect, your problem is 1. Dieter

object.changeOwnership (con't)
by Gilles Lenfant 23 Feb '02

23 Feb '02

Hi, Are there ownership experts here ? I noticed that in lib/python/AccessControl/Owned.py in the Owned class, the "object.changeOwnership(user)" (line 97) method calls "new = userInfo(user)" (line 234). Then userInfo() checks "user.aq_inner.aq_parent" (line 240) The strange thing is that an user object (from any acl_users) has no "aq_inner" nor "aq_parent" attribute. And this raises an AttributeError when trying to change ownership. Did I take a wrong user object type (acl_users.getUser('foo')) or is this another bug ? TIA --Gilles Note : the line numbers are for the Owned.py coming with Zope 2.5.0 or CVS revision 1.15

Web publishing using Zope and GNU TeXmacs
by Joris van der Hoeven 23 Feb '02

23 Feb '02

Hi, We would like to have tools for publishing on the Web, using Zope and GNU TeXmacs (see http://www.texmacs.org) The main idea is very simple: 1. Have one or more web sites running under Zope where documents will be published. 2. Make it possible to load/save TeXmacs documents directly from/to such a web site. In addition, we would like to have tools for being able to decorate pages, annotate pages, referee pages, catalogue pages, search the site, rate pages, costumized navigation, history management, display news on (certain topics of) the site, automatically create online journals, and much more. We are searching for volunteers who know Zope well to help us with this project. The idea would be that one group of people writes the necessary tools on the server side (which might also be useful in combination with other frontends than TeXmacs) and that we take care of the application side. We might start as follows: 1. Someone sets up and maintains an experimental server somewhere on the web (later this might be done on texmacs.org) 2. We agree on a good protocol for saving & loading documents. One might for instance use the post method of a form in order to save (a region of) a document. 3. We are working on Html/Xml converters and web support inside TeXmacs; it would be nice to automatically generate Html translations (for instance) of TeXmacs documents (there might be some information loss here, like the disappearing of mathemematical formulas). Then we might provide an Html version of a page when browsing the site using a conventional navigator and the TeXmacs version when browsing using TeXmacs. 4. Create the necessary administration tools for managing permissions, passwords, etc. This should be easy in Zope, but we might need some conventions on how to do this in combination with TeXmacs. 5. Find a way to automatically decorate the TeXmacs documents, downloaded from the Web, like providing a dynamic header and a footer. These decorations might be in Html (modulo a better Html->TeXmacs converter). As a first goal, these tools may be used to create a collaborative website for the documentation of TeXmacs itself. This might be a good test for a very basic implementation. Next, the implementation might evolve towards a more complete publishing system. So: are there any volunteers ? Maybe it is possible to adapt some existing work on this?

ZPT and traverse_subpath (Python Script)
by Andreas Elvers 23 Feb '02

23 Feb '02

Hi, is it possible to use traverse_subpath inside a python script, that is called by a ZPT ? I tried the following simple test. I call a PScript from a ZPT some extra path info. I expect the ZPT to replace "to be replaced" with a list containing the remaining path elements. But it's not working. Is this a bug or a feature ? :-) Viele Gruesse - Andreas ==== ZPT: ==== <html> <body> <p tal:content="here/pscript/ja/ja/deine/mutter"> to be replaced </p> </body> </html> ============= PythonScript: ============= ## Script (Python) "pscript" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## # Example code: # Import a standard function, and get the HTML request and response objects. from Products.PythonScripts.standard import html_quote request = container.REQUEST RESPONSE = request.RESPONSE # Return a string identifying this script. return traverse_subpath -- ___________________________________________________________________________ Andreas Elvers | n@work Internet Informationssysteme GmbH Email: andreas(a)work.de | Tel./Fax: 040/23 88 09-00/29 | w w w . w o r k . d e
