I try to add a SmartSections object but I get an error. (Formulator and OrderedFolders are installed) Error Type: AttributeError Error Value: getParentNode Traceback (innermost last): File C:\Program Files\zope\lib\python\ZPublisher\Publish.py, line 222, in publish_module File C:\Program Files\zope\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Program Files\zope\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook File C:\Program Files\zope\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Program Files\zope\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_addSmartSection) File C:\Program Files\zope\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: manage_addSmartSection) File C:\Program Files\zope\lib\python\Products\SmartSections\SmartSection.py, line 17, in manage_addSmartSection File C:\Program Files\zope\lib\python\Products\SmartSections\General.py, line 9, in findFormContainer File C:\Program Files\zope\lib\python\Products\SmartSections\General.py, line 9, in findFormContainer (Object: ApplicationDefaultPermissions) File C:\Program Files\zope\lib\python\Products\SmartSections\General.py, line 8, in findFormContainer AttributeError: (see above)

viewing newsgroups
by Joe Gaffey 05 Jul '01

05 Jul '01

Hi, Apologies to anyone who may be receiving this a second time ;( I am trying to use a web front end to view already existing newsgroups on an nntp server. I was wondering if there are any zope products out there that will do this for me. I do not need it to act as a mail server or anything like this. I had a quick look at zopeGUM but this seems to be saying that it *will* provide something that may do this for me. Any help/suggestions would be appreciated. PS - is this the correct/best place to ask this question? Thanks, Joe.

www.Zope.org frontpage
by Peter Bengtsson 05 Jul '01

05 Jul '01

Hello you who can change the appearance of Zope.org Wouldn't it be great if at the frontpage, there was instead the latest How-Tos or Tips or Products. One of the best developers sites on the net is PHPBuilder.com http://www.phpbuilder.com/, and the front page they have the latest articles in big with little mugshots of the article authors (which feels very personal and friendly). I don't mind going over to Zopelabs.com for the latest recepies and ZopeZen.org for the latest Zope related diskussions. ZopeGeeks.com is coming up strong and will aim to be like PHPBuilder.com or the old ASPToday.com, but they are not going to have the How-Tos and Tips for a long time. Perhaps ZopeGeeks could "steel" that content from Zope.org and ask zope.org members to upload a mugshot.gif in their Members folders. Just something I want and I kindly ask for. Peter

Python scripts - DB connection question...
by Lee 05 Jul '01

05 Jul '01

Hi there, I haven't used Zope for a few months - I'm now using Python scripts instead of the Python method product. They don't appear to be too dissimilar, but I'm having a little trouble trying to execute an SQL query from a script. In a Python method it would be something like: db_conn = self.Gadfly_database_connection() // generate SQL result=db_conn.query(updatePersonSQL) This doesn't work in a script though. Could someone how to estabish a connection and execute a query? Thanks in advance. - Best regards, Lee

Re: [Zope] begin/commit

Hi Gustavo, for advanced "playing" just create a ZSQLMethod instance and play with it. It has more options then the simple test purpose on the connection object, which is obviously only there to simple test success with the connection and may be to create some tables on the fly. Certainly not to retrieve more then 1000 rows out of the database. (which sounds like not a good idea anyway in the web environment, thus the default value is set to 1000 - see advanced tab on ZSQL Methods) Regards Tino --On Dienstag, 3.

Hi, Judging only from response time, throughput handling, download speed, which way to serve large files has better performance, from ZOSB or as external file by LocalFS product?

If there was a published API. The documentation is all over the place. Now I have a different problem. My ZClass python script method now looks like this if username not in context.Members: context.Members.append(username) new_members = context.Members context.propertysheets.Membership.manage_changeProperties(Members = new_members) return 1 return 0 The problem is that this changes the properties of all the objects not just the one I'm interested in. It's as if "context" is the class not the instance.

Assigning a Role Based on IP Address (domain)
by David Legg 04 Jul '01

04 Jul '01

Hi all, I want to assign a user a role based on their IP address or domain. Looking through the Zope book this seemed fairly straightforward but I can't get it to work. The folder I am doing this in is one up from the root level, so I can then lock things down from this folder up. This is what I did: 1. Created a new role called internalUser 2. Created a new user called anon, but didn't fill in the password fields, specified the domain as *.mydomain.com and selected the role as internalUser. 3. Created a DTML document (no security assigned) and did a <dtml-var "AUTHENTICATED_USER.getRoles()"> to see what role was being assigned. When I log into the document anonymously it still displays the role as anonymous - yes I am in the right domain. When I set the security settings to lock out anonymous but enable internalUser to view the page it still prompts for a username and password - even though I didn't specify a password. Looking at the user anon in acl_users the password field is filled even though I didn't specified password - is this normal? Strangely when I give this user a password and log in the ip/domain restriction works - there must be something going amiss somewhere.. The reason why I would like to do it this way is so that I can conditionally show/hide parts of a page based on this role just to give you some context - provided it assigns the right role based on domain/ip! If someone could provide some step by step instructions as to how they did this (I cannot for the life of me see what I'm missing) and a possible workaround perhaps using REMOTE_ADDR - I would dearly like to avoid this! Thank you in advance David

Zope on LinuxTag in Stuttgart!!!!! Booth: 5.0.334.1
by Joachim Werner 04 Jul '01

04 Jul '01

Hi everybody! This is a final reminder, mainly for the European audience ... I am writing you this from our EuroZope booth on LinuxTag in Stuttgart. The booth is really cool (3m*4m, with three presentation points and a little table to discuss more in-depth problems). If anybody wants to drop in: The booth number is 5.0.334.1. We also have three Zope presentations in the workshop area. They are easy to remember: >From Friday on, they are always at 13:00 (1:00 pm) -- Zope High Noon! These presentations are held by me, Stephan Richter, and Veikko Wünsche, and they are for a Zope-insterested audience rather than Zope experts. Stephan also has a presentation on Sunday in the official congress program. See you at LinuxTag or maybe in Berlin at the EuroZope conference next week! Joachim
