Help! Can't unsubscribe!
by T.J. Mannos 17 Nov '00

17 Nov '00

Help! I'm trying to unsubscribe from this list because it's filling up my mailbox too fast. However, when I try to use the web interface or the e-mail interface to unsubscribe, it gives me an odd error message. It says something to the effect of, "There's something wrong with your account. Please contact the postmaster." Yet I keep getting zope-dev messages. Could somebody tell me how to get off this list? Thanks, T.J.

Two glaring omissions
by Alexander Limi 17 Nov '00

17 Nov '00

Hi, I've been working with Zope for almost two years now, and there are two things that I feel is missing in the interface: 1. The ability to add a Base class after the class is created 2. The ability to rename properties after instances of the classes have been created (and have the data in those fields preserved) Are there any technical reasons why these are not present? I know it is possible to add base classes in retrospect via the hack described in http://www.zope.org/Members/AlexR/ChangingBaseClasses but are there plans for making this easier? As for #2, it is quite annoying and counter-productive not being able to change a variable name that was decided a long time ago, or maybe by others simply because there exist instantiated objects of that type. Both of the above are pretty essential OO techniques (for me, at least), and hinder my work quite a lot by not being there. Any chance of these being fixed at all? Or are there reasons that I do not know about that makes this impossible? Regards, -- Alexander Limi alexander(a)mp3.no

redirect and POST
by Robin Becker 17 Nov '00

17 Nov '00

I seem to get different behaviour when I use method=POST in my forms and then attempt to use RESPONSE.redirect later on in the handling method. It seems as though the method that was used to call the form handler is passed on. Then my index_html hangs waiting for the POST data. Is there a way to change the http request back to GET. -- Robin Becker

I'm not running Warp anymore, but that error indicates that python can't find 'Makefile.pre.in', which is part of the source distribution for Python. Are you using Jeff Rush's binaries? I think you need to check out his source distribution (RPM, no less!), at: http://www.os2warp.org/%7Ejrush/python_os2/files.html Best, Tres. -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

The Parsed XML project is now public and ready for input. Parsed XML is the successor to XMLDocument. We have a wiki at <http://www.zope.org/Wikis/DevSite/Projects/ParsedXML>. zope-xml(a)egroups.com is also a good place for discussion at this time. -- Karl Anderson karl(a)digicool.com

How do I create folders/methods etc. within the code?
by Espen Sorbye Frederiksen 16 Nov '00

16 Nov '00

I am a very novice zope/python user that needs to become an expert as soon as possible, since my whole dissertaion is based on Zope/Python. I have read all documentation availible on the zope.org site but can't find the answer to the following... 1. To run python scripts written as dtml methods. Do I simply use dtml-call from another dtml document/method? 2. To create folders, mthods etc in the code. I have found some functions manage_addDTMLMethod, manage_addFolder, but how do I use them? 3. I need to make a site that allows users to register ( i.e. to generate user folder with some standard documents in them). Anyone have hints regarding this? (or in fact a whole application I can use?) I appreciate any kind of contribution, Espen

Folders w/Customizer Support
by Chris Withers 16 Nov '00

If a FwCS, supports a meta_type, does that mean it has to provide everything for DataSkins of that meta_type? To put it another way, could you have a FwCS that provided soem properties and let another FwCS further up the acquisition tree supply the rest? cheers, Chris
