FYI, I've put up the various comments for possible discussion points on an Enterprise Zope BOF: http://www.zope.org/Members/paul/EnterpriseZopeBOF.html As for date and time...dunno. How about 7PM, just after the CMF BOF, same location? Alternatively, 6PM Wed night? --Paul > -----Original Message----- > From: Spicklemire, Jerry [mailto:Jerry.Spicklemire@IFLYATA.COM] > Sent: Friday, March 02, 2001 10:34 AM > To: 'zope(a)zope.org' > Cc: 'tseaver(a)digicool.com'; 'mindlace(a)digicool.com'; > 'paul(a)digicool.com' > Subject: BOF at Python Conference > > > Hi Zope and Python Fans, > > So far there have been two topics proposed for Zope > "Birds of a Feather" gatherings: > > Content Management Framework (CMF, aka PTK) > > ZEO and Mission Critical Zope > > Can anyone hazard a guess as to when these might take place, > for those of us who just can't manage a four day trip this > time? > > Thanks, > Jerry S. > >

Some doubt about how to best assign user rights.
by Max Møller Rasmussen 05 Mar '01

05 Mar '01

I have the following hierachy: school class 1 student 1 student 1 content student 2 content etc. student 2 student 3 etc. class 2 class 3 etc. And basically there is three different typs of users: Administrators Teachers Students My problem is that I want to give each student the right to edit the content in their own folder. Their folder is a zClass that subclasses objectmanager, and they can only add certain other classes. Now how do I best set out to do that? It should also be easy for the teacher to administer his students. The options I can see: - Make an acl_users folder in each student folder, and give the student the admin role in that folder. That would work but seems a bit longwinded. - Make a student an owner of a folder? (I am not really shure what consequences that would have) Regards Max M

Importing external document
by ASHISHRANJAN_V 05 Mar '01

05 Mar '01

For that I used external method : import urllib def fetch_url(self, url): return urllib.urlopen(url).read() And called it in index_html file as : <dtml-var standard_html_header>    <dtml-var standard_html_footer> Problem is when it fetches the html page , it also changes the relative links in html page . Is there a way I can make the links point to respective resource at orignal site. Ie use the parameter url to be embedded in html link Like href="/help" Converted to href="url/help" Ashish R Vidyarthi mailto:ashishranjan_v@infy.com

hi, I will create a file using python method and it will be in root directory of Linux server. Now I would like to add it to Zope as a file. file means as we add from "Add available Objects"(here it will ask us to browse from windows machine.) I would like to add by writing Dtml method.(it must take from the Linux machine.) How to do that. subrahmanya.

very cool. first impression :- it does make making zope products easier. i will give it a shot and hope that i can churnout zope products like you experienced mages :) this is similar to mkzprod... almost, except that mkzprod is zclass like. thanks -----Original Message----- From: Paul T <paul(a)pault.com> To: zope-announce(a)zope.org <zope-announce(a)zope.org> Cc: zope(a)zope.org <zope(a)zope.org>; Chris McDonough <chrism(a)digicool.com> Date: Monday, March 05, 2001 6:00 AM Subject: [Zope] ANNOUNCE.

Mixing VirtualHostMonster, ProxyPass and RewriteRules
by Itai Tavor 05 Mar '01

05 Mar '01

Hi, I'm using ProxyPass and VirtualHostMonster to serve Zope with Apache, and I want to add the force-manage-on-https trick that was mentioned recently, as well as serve some static Apache content. My problem is that I need to use RewriteRules to achieve these things, and RewriteRules don't seem to work alongside ProxyPass. I guess I could replace the ProxyPass with rewriteRules for accessing the Zope server, but then I lose the transparent proxy. And that would be a shame. My main server config is: <VirtualHost _default_:80> RewriteEngine on RewriteLog logs/rewrite_log RewriteLogLevel 9 RewriteRule ^/manual(.*) /manual/$1 [L] # Access Apache's manual RewriteRule manage(.*)$ / [F] # Block access to management screens ProxyPass / http://localhost:8080/VirtualHostBase/http/10.0.1.20:80/ ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/10.0.1.20:80/ ProxyPass /misc_ http://localhost:8080/misc_ ProxyPass /p_ http://localhost:8080/p_ ProxyVia on </VirtualHost> But the RewriteRules are being ignored. They work ok if I disable the ProxyPass directives.

Re: [Zope] Promplems with TinyTablePlus

Apparently not. It seems, you are using "manage_addTinyTable". Your Z instances lack such a method. Thus, acquisition jumps in and you get the method of the folder above. This method, of course, adds in the folder not in you Z instance. You can try "manage_addProduct['TinyTable'].... (you must replace the last three periods with the constructor name). Dieter

Using "external" components such as MySQL (was: [Zope] dd)
by Dieter Maurer 04 Mar '01

04 Mar '01

Patrick Miller writes: > how do I tell zope which python to use. and add the zmysqlda to it? The script "start" controls which Python is used. The environment variable "PYTHONHOME" (defined in "start") controls where the Python infrastructure is searched for. You can use the environment variable "PYTHONPATH" to let Python look at additional places for modules and packages. PYTHONPATH is a colon separated list of directories. Alternatively, you can make appropriate symbolic links to the external components (usually in "<zope_dir>/lib/python". Dieter

Re: [Zope] Problem with manage_ChangeProperties

Put it into the Collector: after "manage_changeProperties" almost completely did its work, it wants to return "manage_propertiedForm". This objects wants to use "manage_page_header". However, apparently, this object is not accessible via your "doc". As a workaround, you have two options: 1. pass the properties as keyword arguments: doc.manage_changeProperties(foo=bar) 2. catch ("dtml-try ... dtml-except") the exception and ignore it. Dieter

MySQL, ZMYSQLDA and date fields
by Salvatore Sciacco 04 Mar '01

04 Mar '01

Hello, I've a MySQL table with some datetime fields (not null). By default MYSQL put '0000-00-00 00:00:00' (a zero date) in these field. When this happen I can't select these fields anymore because Zope raise an invalid date format exception. Do you know a workaround for this problem? Thank you. -- Best regards, Salvatore Sciacco mailto:sas@prometeus.net
