Hmmm. Sounds like you need to start with a Forms tutorial: http://hotwired.lycos.com/webmonkey/99/30/index4a.html Then, the Smarter Forms tutorial: http://www.zope.org/Members/jules/smarterforms_html hope that helps. Troy -----Original Message----- From: Oliver Vecernik [mailto:vecernik@aon.at] Sent: Monday, January 22, 2001 5:23 AM To: zope(a)zope.org Subject: [Zope] form question Hi all, I'm a newbie to Zope and Python. Nevertheless I'd like to start with it. I'm designing an application gathering data with forms. Navigation should be done with Prev and Next buttons. As long as I'm not leaving the form data should be entered, processed and the *same* or another form should be displayed, depending on input of the user. So far I'm able to gather data, store them in a database, but can anybody give me a clue or point me to some docs how to control which form should be displayed next? It should depend on users input of let's say a text field.

Hello, Where can I find (and use) the variable REMOTE_ADDR? I've a python function that deal with REMOTE_ADDR, but I've got the IP address's Zope Server Machine. I looked at Z2.log and find the same IP, ie. the address's Zope Server Machine. I need the remote address. I'm using SiteAccess and Zope 2.2.4 on Linux. I don't understand ... Thanks in advance.

RE: [Zope] Object DB versus Relational DB
by Farrell, Troy 22 Jan '01

Maybe you need an ORDB (Object-Relational DB) like postgresql. PGSQL supports Inheritance: http://www.postgresql.org Troy -----Original Message----- From: Luciano Ramalho [mailto:luciano@hiper.com.br] Sent: Monday, January 22, 2001 6:12 AM To: Tom Deprez Cc: Rik Hoekstra; zope(a)zope.org Subject: Re: [Zope] Object DB versus Relational DB ZODB with Data.fs is optimized to fetch data. Inserts or updates have a lot of overhead. It's the price we pay for the excellent versioning features. Therefore, when the are many we have been avoinding ZODB even when the problem domain calls for an OODB We have implemented a highly hierarchical database for a Yahoo-like directory using a recipe found in the book SQL for Smarties, by Joe Celko, ISBN 1-55860-323-9 (see Chapter 26 - Trees). Celko's solutions allow for a hierarchy with unlimited levels and, amazingly, it does not require sub-selects or any other construct unsupported by MySQL. The rest of the book is filled with solutions to problems that test the limits of the relational database model.

Is it possible this is another issue with 2.0 (I'm no python guru :)? FR, Zope 2.x is designed to work with Python 1.52.

Zope 2.3.0b2 bug #2
by Oleg Broytmann 22 Jan '01

22 Jan '01

It is not exactly bug, but VERY unplesant misfeature: Zope now sends all HTML in management screens with <meta http-equiv="content-type" content="text/html; charset=iso-8859-1"> This is WRONG way of doing! Please stop it and don't do it :) Meanwhile - where I can turn this off?

Selection property problem
by peter bengtson 22 Jan '01

22 Jan '01

This is the form: <select name="alignment_text"> <option>left</option> <option>center</option> <option>right</option> </select> When I submit this form the <dtml-var REQUEST> says this (assuming I select 'center'): alignment_text: center With this I want to change a Selection property called 'alignment_text', but it fails to "None" all the time. <dtml-call "propertysheets.text_props.manage_editProperties({ 'alignment_text':_.str(REQUEST['alignment_text']), })"> All other properties are ok, except this one that selection one. What's the trick? ...with selection properties. PS. My HTML (the form) looks the same as is does when you click the Properties tab of this object.
