Catalogaware ZCLass and deleting
by Sven Hohage 29 Jan '01

29 Jan '01

Hello, I try to delete a Catalogware ZClass with subobjects that are also ZClasses. That's my method to delete a Class: -->> <dtml-in "objectValues('ZClassPage')"> <dtml-let x=sequence-item> <dtml- if "in_work"> <dtml-call "manage_delObjects([x.id])"> </dtml-if> </dtml-let> </dtml-in> But Zope answers: An exception occurred in a DTML method or document. Error type: BadRequest Error value: 980785769 does not exist But '980785769' EXISTS in the management-interface !! :-(( Thanks!

Python script safety
by Robin Becker 29 Jan '01

29 Jan '01

There seems to be some attempts to avoid DOS attacks by eliminating excessive resource usage. Might I point out that the first script I tried out m=range(99) m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] m=[m,m[:],m[:],m[:],m[:],m[:],m[:]] return m seems to be taking an awful lot of my machine's resources -- Robin Becker

namespace problems
by Gary Lowder 29 Jan '01

29 Jan '01

I'm currently trying to add a new folder to an old folder, using input from a calling form, then add two properties to that new folder. I searched the mailing list, and came up with an example that led me to the following, but I'm still getting "Error Type: NameError" "Error Value: manage_addProperty". Where is my mistake? <dtml-comment> The following line works as expected.</dtml-comment> <dtml-call "manage_addFolder(name)"> <dtml-comment>Something below here isn't right.</dtml-comment> <dtml-with "_.getitem(name)"> <dtml-call "manage_addProperty(id='number', value=number, type='int')"> <dtml-call "magage_addProperty(id='exp_date', value=exp_date, type='date')"> </dtml-with> <dtml-call "RESPONSE.redirect(URL1)"> Thanks for you help!

Hello everyone, I want to make my own name space with the following situation: class X: attributes = {'foo': 'bar'} x = X() Then I want to use it like that: <dtml-with x> <dtml-var foo> </dtml-with> The result should be : bar I found out that I have to somehow use TemplateDict and InstanceDict, but I have no clue how to use it....Of course there is no documentation on any web site or in the Zope code itself....

problems with URL passing again
by Horatio B. Bogbindero 29 Jan '01

here is a piece of code from article.html: <center><table width=60%><tr><td> <b><center>*<dtml-var pass_id>*</center></b> <dtml-in "articles.objectValues()"> <dtml-var expr="id==pass_id"> <dtml-if expr="id == pass_id"> <p><b><dtml-var title></b> <dtml-var sequence-item></p> </dtml-if> </dtml-in> </td></tr></table></center> then i access it via http://localhost:8080/article.html?pass_id=validid and validid is a valid id of a dtml method in the articles folder. however, i get weird results: *validid* 0 0 which is weird because getting a 0 0 means that none of the ids matched. more weirdness? -------------------------------------- William Emmanuel S.

"migration" issues - 2.2.4 -> 2.30
by Lee 29 Jan '01

29 Jan '01

Hi there, I've been developing an application on Win32 using Zope 2.2.4 and a Gadfly database. Now that I've got a working prototype I will me rebuilding my app on Zope 2.3 in Unix using a MySQL database... tomorrow. I expect the process won't be a simple job i.e. copying & pasting *won't* do the trick ;-) I just have a few questions about the problems I expect to run into: 1- Python methods/scripts. In changing my python methods to python scripts will I need to make any drastic changes or will they perform just the same if I have the *exact* same content in them? 2- MySQL DBA. I'm not responsible for installing Zope or the MySQL DBA on the Unix machine but from what I understand, people have had a few problems working with MySQL DBA. What problems can I expect? 3- I would like to backup what I have done on my home machine and copy it to another windows machine at uni (that I can reference when I'm building on the Unix version). I don't have access to the Unix machine from outside uni so, apart from copying the source into text files, is there a way I can *copy* Zope's files and place them on another machine? Hmm... I expect I'll be bombarding the list with questions these coming weeks. Thanks in advance for any information/advice you can offer. - Best regards, Lee

MYSQL Problem
by Jens Grewen 29 Jan '01

29 Jan '01

I installed mySQL-3.23.32 mySQLdb 0.3.1 ZmySQLDA 2.0.4 on Win98 >From the following SQL statment I get the result 233L and not 233 as expected select count(PID) from product When I run this SQL Statment from another program I get the expected value 233. In my installation there are a lot of Z SQL Methods that should return an int value and when I use field description int in the database I always get this 'L' behind the expected result. A lot of things don´t work because of this. When I change to mediumint (database field description) I get the expected 233. How can I fix this. Thanks Jens

[Zope+SybDA]Multiplexed or not ?
by Tony Moutaux 29 Jan '01

29 Jan '01

Hi list! I run: -zope 2.2.4 -python 1.5.2 - solairs (sunos5) on ES450 and the ZopeSybase DA v2. I am not sure if the SQL transactions are multiplexed (I mean that I can run several SQL requests at the same time). I try : /A/firstZSQLMethod - firstSybDA /B/anotherZSQLMethod - anotherSybDA, but on the same sybase server in two browsers running in two differents computer, and it seems the second transaction is always waiting for the first to finish, before running (so it will mean there is no multiplexed). I'm not sure what the problem is, how to test and perharps fix it. What I know is that the SybaseDA v2 claimed to be fully multithreaded. But now : -How do I test if Zope+SybDA is truly multiplexed ? I have try 2 simultaneous requests, but there is so much parameters (os, python, zope, sybda ...) that I don't know if it is the right direction. -How do I test if Python 1.5.2 is trully multitrheaded ? It is "home mad", I have to compile it with the Sun C compiler because there is no GNU tools on our system, and I have done a lot of work to have python compiling. So perharps I miss something about multithreading in python. Thanks a lot for advise. Tony
