Bizarre bug - "floating" ZClasses
by Lalo Martins 18 Sep '00

18 Sep '00

I finally went to upgrade our production machine (the one which runs cosmetica.com.br and hackandroll.org) to Zope 2.2. When I did (and after upgrading SiteAccess and updating its objects with the provided script), BannerFolders and BannerAds stopped working. So, I went to the Control Panel and deleted the product, to install the newer version. Before that, Zope was restarted, and suddenly the Banner objects started functioning normally - with their Product missing! On top of that, I tried to install the Product and it gives me a "Duplicate Class Ids" error... It's been a while since I've been so puzzled and impressed by a bug :-) []s, |alo +---- -- Hack and Roll ( http://www.hackandroll.org ) News for, uh, whatever it is that we are. http://zope.gf.com.br/lalo mailto:lalo@hackandroll.org pgp key: http://zope.gf.com.br/lalo/pessoal/pgp Brazil of Darkness (RPG) --- http://zope.gf.com.br/BroDar

string to list?
by Nitesh Dhanjani 17 Sep '00

17 Sep '00

Hello, I have a Z SQL method which returns me a string like {{"a"},{"b"},{"c"}} Is there anyway I can write a dtml-in loop to pick out each element from the string? I want to be able to do something like: <dtml-in my_zsql_method_which_returns_a_string> <dtml-var element>, </dtml-in> and that should give me "a,b,c". Is this possible? Or do I need to write an external python method to return a list["a", "b", "c"] given the string above? Thanks! nitesh

Python Methods 0.1.7 under Zope 2.2.1
by J M Cerqueira Esteves 17 Sep '00

17 Sep '00

Working with Zope 2.2.1 (in two distinct servers), I noticed the following behaviour with (0.1.7) Python methods (created under Manager role): 1. Apparently anyone (non-authenticated users) can successfully run the methods even if these include operations (folder/file/user creation, etc.) for which the invoking user has no permission. 2. Although I am able to give Python methods the proxy role of Manager, I can not give them other proxy roles, roles which I also have and am able to give to DTML methods, for instance (anyway, problem 1 makes privileged proxy roles superfluous... :) ). Has anyone fixed this (while we wait for the new shiny Python methods)? Best regards & thanks in advance J Esteves -- jmce: +351 919838775 ~ http://artenumerica.com/ ~ http://artenumerica.org/

Mailhost problems (was: [Zope] (no subject))

This looks like a wrong "dtml-sendmail" format: the closing '>' of dtml-sendmail comes before "Subject", the empty line separating the message header from the body is missing. Try: <dtml-sendmail mailhost="MailHost3" mailto="vikas <suhail(a)morelinux.com>" mailfrom="suhail <suhail(a)morelinux.com>" subject="<A new Snippet has been added to ZDP !>"> COMMENT: Note the empty line above !!! Dear Rik ! ... </dtml-sendmail> Apparently, "dtml-sendmail" does not create "To" and "From" headers from the "mailto" and "mailfrom" arguments.

Domain name required Somehow, your SMTP server is unhappy about the request. As both your "To" and "From" contain domain names, only "hostname" is a bit doubtfull. But there should be no domain name necessary for it. When I checked the "dtml-sendmail" on Zope 2.2.1, I have been successful with: <dtml-sendmail mailhost=MailHost> To: dieter@localhost From: dieter@localhost Subject: A test Hello </dtml-sendmail> Similar problems have come up some weeks ago in the mailing list. Search the (searchable) list archive. Maybe, you can contact the person with this problem and check whether he was able to solve it. Dieter

The "libcrypt" reference is probably only a warning. You may look at the various "config.*" files to obtain more information about the configuration process and why it failed. Dieter

Re: [Zope] set date property from External Method

Zope does not store the properties as strings but as objects of the correct type. If you use the "PropertyManager" interface (as you should), then string values are *converted* to the correct type automatically. Dieter

I think, you can customize URL generation. The default method is "tpURL". I did not try it, however. And I may be wrong that it can help you. Dieter

Zope to PostgreSQL Connection?
by Cesar A. K. Grossmann 16 Sep '00

Hi I'm with some troubles to connect a freshly installed Zope 2.2.1 on a Conectiva Linux 5.0 (glibc-2.1.2, the rest is the same as Red Hat 6.x) to a PostgreSQL 7.0.2 database. The ZPyGreSQLDA (http://www.zope.org/Members/reedstrm/ZPyGreSQLDA-rjr) "is broken". I tried to get the PoPyDA working, but cannot compile the PoPy module (it complains about libcrypt - that is already installed). Can someone point's me to a useful documentation about what is needed to get PoPy compiled, or another way to connect a Zope 2.2.1 to a PostgreSQL database. Trying to compile PoPy 1.3.6: [root@bit PoPy-1.3.6]# ./configure loading cache ./config.cache checking for python... /usr/bin/python checking python version... 1.5 checking python installation prefix... /usr checking python installation exec_prefix... /usr checking definitions in Python library makefile... done checking location of python library... $(prefix)/lib/python1.5/site-packages checking location of python shared modules... $(exec_prefix)/lib/python1.5/site-packages checking for main in -lcrypt... no Warning: next test can fail because of a missing libcrypt checking for PQconnectStart in -lpq... no configure: error: can't build without PostgreSQL libraries Do we have a crypt library somewhere?
