"creating XML Applications With Zope"

In Amos Latteier's "creating XML Applications With Zope" at http://www.xml.com/pub/1999/12/zope/index.html There is an example that uses a Zcatalog. He says to enter this into the expr field of the "Find Items to Zcatalog": getNodeName()=='entry' and click find. When I do this with my own version, or even his version Zope gets this error: Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: Eval it has to do with that entry in expr. Is that a typo?

Client-side Zope
by Sin Hang Kin 04 Mar '00

04 Mar '00

Continue to moving more job to the client, There will be more for Zope to perform: 1. There will be necessary to generate various section-specific temporary objects for CSS, DTD and Scripting files, framed or embeded html. 2. There will be necessary to support java or javascript access of zope in the client. In the first requirement, I would like to suggest an machenism to create an section specific temporary object (which zope create the unique name and substitute it) which dtml is able to write to it. The new object can be just a new dtml-document. As in the following <dtml-object dtdobject> <dtml-object scriptobject> <dtml-object cssobject> <script lang="javascript" src="<dtml-var scriptobject>"> .... <dtml-write target=scriptobject> function <dtml-var uniquevalidfunctionname>(){ .... } </dtml-write> I don't known about the solution of the second request. In the long run, zope might encourage separate of control and data. The current opening all tags in one dtml-method and closing them in another is very dangerous if the control get complicated. I would like to suggest DC consider a xslt like syntax which can also be used in server side xml to html conversion if the client do not support it. If zope is going seriously to the international market and xml, then unicode is important in the core level.

Re: [Zope] Perchance a dtml major mode for XEmacs?

The link below explains how I managed to create such a beast: http://www.zope.org/Members/alburt/dtml_mode It relies on a DTD file to define the format of DTML code and then letting PSGML, a package for editing SGML/XML code, do all the work. --- Alastair Burt

RE: [Zope] Changing superuser password (Quest)

Thanks. That's right, I didn't write the username thinking the default was superuser. Inserting it made my change bcome effective.

KM|Net News 1.1
by Kevin Dangoor 03 Mar '00

03 Mar '00

KM|Net News is a Zope through-the-web Product that allows you to post news-style articles on your site. 1.1 is easier to install (because it creates its own Catalog and does not have any external methods) and now incorporates linking to external sites for more weblog-style publishing. (KMNN is still different from Squishdot in that there are no discussions attached to the articles and has different features for placement of the articles within the article listings). You can see KMNN 1.1 in action at http://www.byproducts.com KMNN 1.1 also includes a new "contrib" method for trusted people to contribute articles without review. *** KMNN 1.1 requires PythonMethods. *** You can get KMNN here: http://www.zope.org/Members/tazzzzz/kmnn If you're upgrading from an earlier KMNN, you may want to use the "Restore Defaults" tab to "Rebuild Catalog" and restore "incoming.html". The new incoming.html adds the fields for external articles. This will probably be the last major revision of KMNN before the PTK. Kevin

RE: [Zope] Trying to do something tricky (for me, that is)
by Andrew Henshaw 03 Mar '00

Okay, never mind. I figured it out. I needed to use: expr="REQUEST.has_key('division') to determine if the 'division' has been defined. Also, the passing of multiple variables was obvious - just define a hidden input field. Thanks, anyway. -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Andrew Henshaw Sent: Friday, March 03, 2000 2:03 PM To: zope(a)zope.org Subject: [Zope] Trying to do something tricky (for me, that is) Okay, I'm new to Zope (3 days), but I was having such success with some simple things that I thought that I could handle something tricky - I've been working at it for a day now. What I would like to do is present two selections (Division and Team) that are populated from an ODBC connection. I can do the population fine, normally; but the trick is that I'd like to have the Team selection dependent upon the Division selection (on the same web page). I realized that I couldn't do this on a simge form (or can I?), so I've assigned the two selections to two forms. I'm putting the two forms on the same page for aesthetic (stubborness?) reasons.

When I submit the form, the same page is regenerated (with the 'division' parameter passed in).

When the user first enters the document, he gets an KeyError on 'division'. I understand why this is so (the division parameter doesn't exist yet), but I can't seem to work around it . I tried changing the sql parameter to divisionname and changing the <dtml-in> tag to: <dtml-in expr="sqlTeamsInDivision(divisionname='<dtml-var division missing>')" size=50 start=query_start> and the error goes away, but the returned list is just blanks. How should I be handling this? Also, when this form is submitted, it calls TeamSchedule with the 'team' parameter, but I need to also pass the 'division' parameter. How do I do this?

Re: [Zope] Worldpilot IMAP Bl00z
by Ryan Hughes 03 Mar '00

Hi Tres, Hi Jack, Thanks for the infos/repost. Is there no way to control UW IMAP to look for a specific folder in each user's home dir for the INBOX root? Something like the way http://host/~username/ mapping works in apache? If not, then I'll add this instruction to the upcoming FAQ for worldpilot, since this is the no.1 question up to now. (Jeeze, looks like I'll have to install UW IMAP myself afterall, too.)

How to kill that BASE HREF
by Tom Neff 03 Mar '00

03 Mar '00

If you are sure that you can get along without the BASE HREF in a virtually hosted (or other) Zope page, there is a way to fool the ZPublisher so it doesn't include the obnoxious tag. Just put <base dummy=dummy> near the top of your method. This turns out to be enough to fool the fairly droidal scanning code into thinking that no additional BASE tag is needed. Since it's an unknown attribute it should be a total no-op in browsers. Of course they could write a smarter parser in a future release so caveat Zopor, but it works for now. I wish they hadn't relied on that tag to begin with.

error catching
by Oai Luong 03 Mar '00

03 Mar '00

I'm kind novice in zope, but have learn to work around it. My postgres tables are set up with primary keys and unique index. So if there are duplicate entries it returns from postgres, a nasty error in zope if the submission was unsucessfult, that i have no idea what it is talking about ? is there a way that when the user submits data to the database via form on web site, catch the error if the user try to submit a data to the database that already exists, returned by postgres, and out put an english message saying "your data was not submited because it already exists on the database" instead of that ugly error on the zope end ? thanks to anyone if they can help.
