Hi, First, thanks to everyone that gave me help while I've been learning Zope. It is much appreciated! In the QuickStart material, there are three things mentioned for which I am interested but have been able to find absolutely zero documentation. These are: * Aqueduct * Tabula * Pluggable Brains Where can I find information about them? Thanks, John

(In other words, does > everything work without the module present?) > > -Jeff Bauer Jens, I suspect I know what's going on here - I'd bet that the problem is that: 1. PCGI is failing because Zope is failing to start properly 2. Zope is probably failing to start properly because is it trying to import the oracle interface module. 3. This is most likely happening because the C oracle libraries _require_ that a variable such as ORACLE_HOME be set in the environment of the process that tries to use them (you may want to double check the exact name of the environment variable required - I'm going on somewhat fuzzy memory here). When the the Python oracle interface is imported, the oracle C libs do not find the environment variable and cause an immediate exit. The solution: In your PCGI info file (if the process is being started by PCGI) or in the "start" script that runs ZServer (if you run ZServer manually), you need to arrange for the oracle environment variable to be set. Note that if your setup is such that PCGI starts your Zope process automatically, you just need to add a line such as: ORACLE_HOME=/foo/bar to your PCGI info file. Otherwise you need to either set it in your own environment when starting the process or (better) modify the start script to set it when it is run. Hope this helps!

howto format/customize property sheets for zclasses ?
by chas 06 Sep '99

06 Sep '99

good afternoon, basic question : how does one format/customize the "properties" management page of a zclass instance ? this must be quite obvious but even after a shower i can't find it. eg. say i have a zclass called "Article". creating this via the zope interface will automatically create the following : Article Article_add (Article constructor) Article_addForm (Article constructor input form) Article_add_permission (Article constructor permission) Article_factory (Article factory) i have edited the Article_addForm dtml-document to make the html form better (eg. larger text areas larger with WRAP attributes). so, now it is easier to create a new instance of this zclass. but when somebody wishes to edit/update the properties of this instance, the following form is used : http://domain/[zclass-instance]/propertysheets/properties/manage is there a quick and easy way to over-ride this ? i'm only going to add a few things (like better textareas or comments for users) in the name of usability. (going back to the Lotus Notes analogy earlier, how does one format/customize the "form" ?) cheers, chas

RE: [Zope] Validate fields?

This may be heresy to some folk, but you're probably better off doing this client side, if you are able. The Javascript in Version 4.x and above Netscape (and IE too, I think) has a regular expression engine built in. An re to match all possible valid email addrs could be quite large however: http://enterprise.ic.gc.ca/~jfriedl/regex/email-opt.txt Good luck, Bill -----Original Message----- From: Juergen Specht [mailto:specht@speed-link.de] Sent: Thursday, August 26, 1999 9:35 AM To: Andreas Kostyrka Cc: Zope List Subject: Re: [Zope] Validate fields?

I've been seeing some good buzz on this list about ZClasses. Is there anything I can read to find out what they are and how to use them? I searched the beta site but didn't come up with anything much. -Doug -- Doug McNaught doug(a)mcnaught.org http://www.mcnaught.org/~doug

A tree and a form
by Wim Vanroose 06 Sep '99

06 Sep '99

Hei, Within a <form> I use a tree that is generated by an sql method already dicussed here on the list. After I opened a branch I want to select different leaves with a <input type=checkbox .. > . Problem is that when you open a branch select some leaves close it and go on to select leaves from another branch you are in troubles. Because when you reopen the branch all buttons are unselected. It's impossible to walk thru the tree, select some leaves and afterwards hit the submit button. So one of the possible solutions is to make the +/- signs submit buttons that save the selected items immediatly in the SQL database. Has anybody any other proposals or some hints were to start ?
