In another message, Oleg broke some things down in a way that triggered something in my mind. I would say this: take the existing www.zope.org and make it dev.zope.org (or www.zope.org/dev or something)... a site with a developer focus, and the normal front door that those of us on these mailing lists would use. Look at Vignette's web site. Looking at their front page, there is easy access to a DHTML tour of StoryServer, a snazzy graphic in the middle highlight a couple of things that their products do for you (Speed your development, build e-relationships, extend your brand). There are links to high-level product info, and customer sites. I think it's a good idea to feature sites that use Zope, even if the sites are not well known... because it can give people an idea of things real people are doing with Zope. I would guess, at this point, that you probably won't have too much trouble getting some people to write a few paragraphs of how Zope fits in to their sites (I'd be happy to do so for Byproducts.com) I think having two front pages would be a great thing. We, as developers, want something that gives us quick, easy access to all of the Zope info that keeps us chugging along. But, I'm sure many people coming to www.zope.org are trying to figure out what it does for them. If you (DC) start building a marketing site like this, I'm sure the Zope community would pitch in with ideas for the text if you ask specific questions. (Just think of the response to the Zope banner a couple weeks ago). Kevin

Front door on the Zope web site
by Tom Deprez 27 Oct '99

27 Oct '99

Mmmmm, I don't know of you guys/galls, but... has somebody read the first chapters of ZBook (now already very old, i.e. some months)... It was in our intention to make an introduction to Zope... it stopped (almost) by the lack of interest! Luckely now some people are starting with it again (but it's still a little rusty.. ie. not much people can/will help) What I suggest is: Look at the first 2 chapters of ZBook, not only look, but read... let us know if this is usefull to you... and then HELP to extend it! You can find ZBook at: http://zdp.zope.org/guide/ZBook/ More on ZBook Status at: http://zdp.zope.org/ZBookStatus And also, beginners could find some text at my webpage of Zope... ZDP needs more attention... Tom.

> o What questions should the Zope.org home page, and pages > one click away, answer? > o What are some effective ways to answer those questions? >--Paul Darn right, these are important. When I went to the Zope site, I had almost no idea what it was good for. Now that I've been fooling more with it, I still can't say that I have a full understanding. So how many people will be checking out the site and then moving on? Probably many! I am a Cold Fusion user. I started using it because I needed to retrieve data into web pages from relational databases. Cold Fusion is great for doing that (using ODBC) and for formatting pages. It is very easy to use and to write code for. The markup language is much easier to read and understand than Zope's. I can easily get all kinds of info from the server, including cgi variables. It is very reliable. The documentation is fairly good. The user interface is pretty good, and the the source code editor (Cold Fusion Studio) is an excellent product. So why would I also be interested in Zope? First, Cold Fusion is too expensive for me to use personally or for internal, semi-supported department projects. Second, I like the idea that I could run all kinds of Python code in a simple way. This potentially lets me plug into any Python development project in the future. Third, the pre-packaged products, like discussion groups, etc., offer a very easy way to get started with them. I could also modify them if I wanted to. Fourth, I'm interested in being able to use other platforms. BTW, why isn't this mailing list on Confera? This would be a good illustration of one of Zope's capabilities. Or is Confera too clumsy to use in practice? If so, we should be aware of this and hopefully we can improve it. I think it would be very useful if some key zope applications, actual working ones like a discussion group, were available right from the Zope home page as demonstrations of what you can do with it. The "Zope Exits" section of the site is apparently intended for this purpose, but it is ineffective because 1) the name does not convey the intent, 2) the two links currently present are not good examples of the sort needed (clear, simple, with the relationship to Zope made crystal clear), and 3) you can't tell, when you go to one of these linked sites, what Zope features they use. I would like to acknowledge the hard work and creativity of those people who have worked hard to create and extend zope and its documentation, and I don't mean in any way to criticize their work. But since this topic has come up, let's face it, Zope support and explanation still has a long way to go. Thomas Passin

Javascript vs. Zope
by Itamar Shtull-Trauring 27 Oct '99

27 Oct '99

Javascript (in NS4 at least) cannot have ":"s in element names. Which means that I can't do document.formname.text:float.value = 3 Are there any possible workarounds, or I just can't use Zope types in form fields if I want to access them with Javascript? -- Itamar - itamars(a)ibm.net ---------------------------o----------------------------------------------o Perl/Gimp Greeting Cards | Trust?

ZClasses inside ZClasses
by flight＠mathi.uni-heidelberg.de 27 Oct '99

27 Oct '99

I'd like to setup a site with a simplified management screen, similar to Zope.org in that the editor of the site only has a very limited set of elements to choose from: A two-level hierarchy structured in sections and subsections, and both of them can contain one or more pages. I thought I should use ZClasses to implement this: A product "MySite", inside a ZClass "MySiteClass" (with a base class ZObjectManager). Now I thought I should create a second ZClass "Section" (also derived from ZObjectManager) inside the methods view of MySiteClass, then a ZClass "Subsection" inside "Section" and finally a ZClass "Page". I think that's what the Zope Developer Guide suggests, in "Classes inside Classes" But now I fail to tell MySiteClass that it should only take subobjects of type "Section": The "Subobjects" view of the MySiteClass class doesn't list Section (I guess since it's not a product but only a method?). I'm a bit lost here: Do I have to drop this concept with encapsulated ZClasses and should I instead setup the Section, Subsection and Page classes as products of their own ? Gregor

Zope Distribution Examples (was RE: [Zope] Front door on the Zope web site) web site)

I thoroughly agree with this idea. eg: I've just started on Zope, and I spent *ages* figuring out the correct way to invoke a DTML method with arguments to produce a rollover method. More examples would have helped a lot. Another point, however, is that the examples must be maintained and consistent. By which I mean that the default /QuickStart stuff has references to a lot of things which aren't named like that anymore (Aqueduct, f'rinstance). This is confusing to beginners. However, this is getting away from what is needed on the web site. For that, something like a "what can I do with Zope?" section would be good. Perhaps, showing something like the database examples from the quick start (database integration always impresses people :). The idea should be, however not just to show people what Zope can do, but to give them a brief idea of how to *think Zope*, which might well be quite different to what they are used to. -Dom -- ********************************************************************** This email and any files transmitted with it are intended solely for the use of the individual or entity to whom they are addressed.

New Version of Zope RPMS Available
by Jeff Rush 27 Oct '99

27 Oct '99

I've upgraded my systems to Red Hat 6.1 and just this morning put up new RPMs for Zope that fix problems reported to me re RH 6.1. They are Zope-2.0.1-*5*... and you can get them from: http://starship.python.net/crew/jrush/Zope/Zope2.html On 26 Oct 1999 17:38:29 -0700, Karl Anderson wrote: >I'll confirm that a vanilla RedHat 6.1 dist. with the Zope/zserver >2.0.1-4 RPMs doesn't work.

Correct and since I can't go changing your syslog settings from within an RPM, I removed the env var I had set in zserver.sh that caused it to log via syslog. The original Zope tarball didn't log via syslog either and I added it when I made the RPMs. Compatibility is more important and RPM users can always rework the logging to suit their admin and security policy. I shouldn't by default depend on syslog. On Tue, 26 Oct 1999 19:54:59 -0600, Paul Grunwald wrote: >Thanks for your help, I was able to get it started by following your >instructions.

The problem with /var/zope/zserver.pid only occured on some systems and not others, for no apparent reason I could see. However, the point is moot as I've changed the /etc/rc.d/init.d/zope script to _not_ delete the .pid file when shutting down zserver, so it will work everywhere. One other change -- at Michel's suggestion Zope.cgi now points to an empty file via the PCGI_PUBLISHER line, so that if PCGI cannot find ZServer, it won't try to start one and mislead people when it gets the euid/egid permissions wrong. It will give a 500 - temporary error window instead -- not perfect but the best that can be done w/o reworking PCGIwrapper in detail. -Jeff Rush

How can I create an list_object to use with manage_changeProperties
by jens ebaer 27 Oct '99

27 Oct '99

Hi folks, I've got a little problem because i want to change the properties of a folder object <dtml-with id> #id of the folder objekt <dtml-call "manage_changeProperties(list_object)"> </dtml-with> the list_object must contain the folder properties and the new values of the properties (comming via REQUEST (form-dtml)) {'id':'exampleid','title':'exampletitle'} The creation of this list_objet must be dynamic. So that there is no need to change the list_object if a property were added to the folder object. something like that: {id:REQUEST['id'],title:REQUEST['titel']} How can i create such an object?
