Well, you can use roles as if they are groups, and that roles are Zopes name for groups are a common misconception. > (Is it possible to assign one role to another role? A SuperDeveloper > had developer and super roles?) No, and I don't think it should be possible either. A role consists of the permissions needed to perform the tasks you need in an organisational role. Making groups of roles would add an level of indirection that really has no purpose, and it will only make the user interface more complicated. > LR> But if groups do nothing more than group > LR> principals, then groups are only a way to make assignments of > LR> one principal to several roles quicker. > > Quick has nothing to do with it.

Groups, as discussed so far, are only collection of principals, and are therefore only useful in making assignments of one principal to several local roles quicker. There are several ways of implementing hierachies, and if they promote modularity and makes it easier to reason about a policy depends in part on how that implementation is done. If hierarchies are introduced I think the most useful way would be by creating a user hierarchy with organisational units in which users are placed, a la NDS. It would be misleading to call these organisational units "groups". Hierarchy can be useful, but what is also useful is orthogonality, which you don't get with groups. With "workgroups" you do. > I'm not sure what the innovate roles concept is :-). Thats interesting, since you have been discussing it. :-)

I'm currently trying to integrate a WYSIWYG editor inside the ZMI. You can have a preview at: http://gewis.nl/~pieterb/zope/iedocument/iedocument_preview_mxi.jpg I'm using the following Zope products: http://www.zope.org/Members/arvid/IEDocument http://www.zope.org/Members/sf/HTMLDocument http://vsbabu.org/webdev/zopedev/ieeditor.html I only concentrate on IE only editors (because it's only used for an intranet). They seem to be, based on either: - Microsoft DHTML Editing control (not longer supported by MS), - MSHTML (I didn't get HTML tables to work with it) More references on Microsoft editors: - http://www.microsoft.com/mind/defaulttop.asp?page=/mind/0299/inside/inside0… - http://msdn.microsoft.com/downloads/samples/internet/default.asp?url=/Downl… - http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/editing… There seem to be a lot of inititatives to create new editors, but I didn't find the ideal WYSIWYG editor yet. Hope this helps, Pieter

Announce: CMF Web Agent v. 1.0
by Doug Hellmann 23 Mar '02

23 Mar '02

The CMF Web Agent is an application that allows you to monitor the entire web (or as much as is indexed by several popular search engines, anyway) for new pages related to topics of interest. For example, monitor the web for any mention of your new startup company, and display the results as a news list on your company intranet. Alternatively, monitor the net for your own name or email address and keep the results in your private content management portal. This new release of the CMF Web Agent provides a stable version which has been running in operation on two different sites for several months. New features include a plugin architecture for adding agent information sources. Two search engines (Google and AllTheWeb) are provided by default. New information sources can be built by the user for public (submissions for inclusion in the standard distribution are welcome) or private search sources. Check it out at http://www.zope.org/Members/hellmann/CMFWebAgent. Doug

'Cookie crumb trail' navigation
by Iago 23 Mar '02

23 Mar '02

Howdy. I'll get right to it: Say I have a folder structure, a/b/c I'm in c. I want to establish some kind of method (my current attempts are a python script), stored in a, which will render the following: <a href="http://myserver.org/a/">A</a>: <a href="http://myserver.org/a/b/">B</a>: C: My current attempt only gets me: <a href="http://myserver.org/a/">A</a>: C: Here's the code for recursiveLinks: --- SNIP --- import string if list == None: list = [] if len(list) > 0: list.append( '<a href="%s">%s</a>' % ( context.absolute_url(), context.title or context.id ) ) else: list.append( '%s' % context.title or context.id ) if context is container: list.reverse() print string.join(list,' > ') return printed else: # this doesn't work: return context['..'].recursiveLinks(list=list) return container.recursiveLinks(list=list) --- SNIP --- Now, what I _really_ want is for 'context' to give me an object which is 'the context one level up from here', so I can recursively step up until i hit a folder I somehow designate as "top". I thought I was getting that with context and container, but as it turns out, container, where the above python script (recursiveLinks) lives, is not the container of context (the 'c' folder in this case) -- it's the container of the script (near as I can tell, since the result I'm getting is A: C and not A: B: C) How can I get 'next-folder-up' from this, in an object context so that I can grab the 'title' and other attributes off of the object, and recurse (as I thought I was doing above) by going to yet another 'next-folder-up'? Any help here's appreciated. I'm about 48 hours into learning zope. :) -- Fred Hicks <iago(a)iago.net>

First Release of Quotafolder QuotaFolder is a folder-ish object that restricts the total number of objects, their total size and their individual maximum size. QuotaFolder takes subfolders (recursively) into account, so it should not be possible to escape the quota restrictions. QuotaFolder was developed as part of Amaze Internet Service's FreeZope.org Free Zope hosting service (http://www.freezope.org) More information, and the product itself can be found here: http://www.zope.org/Members/ivo/QuotaFolder -- Drs.

New PropertyManager
by Thomas Guettler 23 Mar '02

23 Mar '02

I would like to add some things to the PropertyManager: 1. mulitple selections should be a list of check-boxes. I don't like the ctrl-click method in the select-box. 2. Would be nice if each property has a second name, which is used for displaying it to the user. This is neccesarry if you have properties with umlauts. Is someone interested in this, or is there already a solution? thomas

"No module named Splitter" on importing an 2.4.3 folder into 2.5.1b1

I've exported a folder from a Zope 2.4.3 server, but when I try to import it into a Zope 2.5.1b1 server I get the error below about no Splitter module; both Zope servers are running on the same Solaris 8 machine.

Re: [Zope] HomeSite 5 and Zope
by hpinson＠indepthl.com 23 Mar '02

23 Mar '02

There is a howto at: http://www.zope.org/Members/cybertad/how_to/homesite Basically, go the Allaire (Macromedia) FTP & RDS, right click on the world icon and add an FTP server ip or domain name, which is your Zope. Here you would add the ftp port (8021 by default; see you z2.py) user name and password (that you have created as a Zope acl_user account. The limit, which I have never seen a solution to, is how to get HomeSite to see zope objects with no extensions. Adding .htm to each zope object you want to edit will do the trick for allowing edits, but there are some negative scripting implications for doing that. I'm looking forward to Macromedia fixing this someday in Dreamweaver and Homesite. No idea if they will. It does not seem to be a priority for them. Have you tried UltraEdit or the newest version of Textpad. I have yet to see if these programs have the above limitations.

RE: Zope in a web based learning environment?
by hpinson＠indepthl.com 22 Mar '02

> Using Zope in a learning environment. If I were writing an open or closed source LMS or LCMS, I'd consder Zope as a highly viable platform. It's got many if not most of the basic services, like authentication, threaded discussions, etc., in the form of freely available Products, that otherwise would cost big bucks from the LMS vendors. Not one vendor i've talked to offers the scalability of Zope ZEOS. The limitations would mainly be the multimedia content module interfaces themselves (AKA Flash, Authorware, Director, Toolbook content). Ferinstance, Flash 5 has big problems with how it does CGI, and I've seen similar problems with the CGI communications Xtras in Authorware and Director. Zope handles this stuff as it should, i.e well. External (flash/authorware/toolbook/director) content can be embedded in the Zope or linked to via a front-end Apache. I can't think of a better way to manage ever-changing html content than a content management system like Zope. You would also need to set up your AICC / SCORM compliant fields in a Zope compatible relational database of your choice, or develop your own tracking standards, but that's not a zope issue. It beats paying $600,000 + maintenance to Click2Learn if all you need is a very simple LMS :o) Harlow Pinson Indepth Learning Email: hpinson(a)indepthl.com Web: http://www.indepthl.com Voice: 505-994-2135 FAX: 208-475-7678
