New to Zope....

... and totally lost into the depth... Hi, I´m struggling with Zope for a few days and so far it looks as it could do the job. But sometimes I feel like never used a (computer)-language before. It´s so different. Maybe I havn´t found the way to think for Zope... The Tutorials are a bit rare or too basic and the documentation is a bit theoretically (IMHO). My way to learn ist "learning by doing" but now I´t totally stuck (maybe its Zope or my brain...). I want to do a site with a title on every page in the different folders which differs only in one word (in real a graphic). So I thought of using a folder property which names this word. I include the title with <dtml-var Titel> and in there is a (html)table with the title and one is <dtml-var titel> where titel is the property of the folder. This property has the value which points to the correct graphic. But it seems that because the "Titel" DTML is in the root of my site it doesn´t know of the folder property "titel" and I get an error : Error Type: KeyError Error Value: titel [···] Traceback (innermost last): File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: index_html) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/OFS/DTMLDocument.py, line 166, in __call__ (Object: index_html) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: index_html) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/OFS/DTMLMethod.py, line 141, in __call__ (Object: Titel) File /usr/local2/Zope-2.0.1-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: Titel) KeyError: (see above) I was also searching for a way to pass some arguments to a DTML function, but with no success. Maybe I´m trying the totally wrong for attaining the desired result. Any suggestion is very welcome so I can go further with my Zope experiments. Thanks, Carsten Wartmann.

Subclassing from homemade ZClass possible?
by itamars＠ibm.net 17 Oct '99

17 Oct '99

I've created ZClass Ant, and know I want to create ZClass Bee as a subclass of Ant. However, Ant does not show up in the list of possible base classes when I try to create Bee. So can I make a subclass of a ZClass?

Hello, I have an product which can only be added to a specific other product (a folder). In its __init__() it depends on aquired attributes from the specific folder, which doesn't seem to be available... (I get an AttributeError).

Zope Newbie
by Joseph A. Martin 17 Oct '99

17 Oct '99

Hello, I am new to Zope. I can program in Python a little bit, Java fairly well, and C not at all. I have used FrontPage (hated it) and straight HTML in the past. All this introduction to say that I am not clueless, but I am not well-informed about Zope. I have played with it a little bit over the past week, lurked here for about 24 hours and skimmed through some of the online docs. What I would like to do is get a really good idea of what I can do with Zope and how to do it. I am not afraid of online docs. What I would like is a recommended reading list. Something to say you can do x, y, and Z with Zope, here is where you can find a brief description of x, y, and Z and here is where the in-depth docs can be found.

Problems with inheritance in python base products
by Sascha Matzke 17 Oct '99

17 Oct '99

Hello, I want to design 2+ products which all share certain base functionality. So I moved some code into Shared. Now, when I try to create instances of the products I get the following error: Error Type: TypeError Error Value: unbound method must be called with class instance 1st argument I use the following code: class B(A): def __init__(self, some, more, parameters): A.__init__(self, some, more) In my python knowlegde the above should be correct... Any hints...

DTML document vs DTML Method
by Tim Haines 17 Oct '99

17 Oct '99

Hi everyone, I'm new to zope. I've been playing with it for a couple of days now, and like it a lot. One thing I want to check I have right is the difference between documents and methods. I have read a few articles, but none seem to address my question. When I have a dtml document rendered, and am viewing the page, I can click on a link, then click on back to go page to the page. When I have a dtml METHOD rendered, and am viewing the page, I can click on a link, but get an error (timeout like) when I click on back. I've also noticed that within a folder, I can refer to dtml methods in the folders above, but get an error when I try to refer to dtml documents. Is this due to my configuration, or are things supposed to happen this way? It would be great if any replies could be sent directly too tim_haines(a)hotmail.com as well as posted to the list. Thanks for your help. Tim.

Experimental searchable mail list archive
by Michel Pelletier 17 Oct '99

17 Oct '99

Greetings, I finally got sick of paging through endless archive messages, so I implimented an expirimental searchable list archive: http://www.zope.org:12080/archives/Catalog/S will present you with a single text search box. This is a very trivial interface, it will be expanded upon. Please try and use this over the next few days and see if it help answer your questions. I used the fsimport script to import the entirety of the pipermail archive, and then cataloged it with the 'Find objects' Catalog tab. In the process, I fixed a silly design flaw that improved the mass indexing speed of catalog by at least 200% and greatly reduced the memory overhead and thrashing. The dataset of documents is 56MB, the total dataset plus indexes is 64MB. Not bad. It took 6 minutes to index the entire dataset with a 10000 word subtransaction threshold and the process footprint grew to 85MB. Catalog has come a long way in terms of speed and memory usage. Further improvements are to parse the documents into rfc822 Messages (probably with a ZClass), index all interesting attributes (date, author, etc), and impliment a simple ZPublisher.Client script that mailman calls to 'push' a message up to the server, instanciate a new message object, and incrimentaly index it in the Catalog. Stay tuned. -Michel

help! zope start failure on linux
by Mike Salib 17 Oct '99

17 Oct '99

hi everybody, i'm running Zope 2 under RedHat Linux 5.2 Every time I start Zope now, I get this error: File "/home/mike/Zope-2.0.1-linux2-x86/z2.py", line 430, in ? logger_object=lg) File "/home/mike/Zope-2.0.1-linux2-x86/ZServer/medusa/http_server.py", line 53 4, in __init__ self.bind ((ip, port)) File "/home/mike/Zope-2.0.1-linux2-x86/ZServer/medusa/asyncore.py", line 205, in bind return self.socket.bind (addr) socket.error: (13, 'Permission denied') I'm not a unix newbie; i've been using unix for years. I know about basic file permission security. I've performed the following commands with no effect: chown nobody.nobody var chown nobody.nobody var/* chmod ago+rwx var chmod ago+rwx var/* I've verified that the var directory itself and all the files contained therein are owned by user nobody and group nobody and that everything is readable, writeable, and executable by user, group and all. I've also tried repeatedly deleting the pid files in the var directory. I've searched the zope(a)zope.org mailing list archives for the last few months. Other people have reported this problem, but some still can't seem to get it working. If anyone could suggest what I'm doing wrong here, please do!
