ZopeLDAP creation problem
by Stephen Harrison 21 May '00

21 May '00

Ok, I'm probably missing something obvious here, but at the moment it's evading me. I've installed ZLDAP, but am unable to create a ZLDAPConnection. Whenever I try I get the error: Error Type: INVALID_CREDENTIALS Error Value: {'desc': 'Invalid credentials'} I've also noticed that if you try to create a ZLDAPConnection and not open it at the same time, you get the error Invalid request The parameter, openc, was omitted from the request. This makes me think that I'm not entering the correct information for the server, but it's not obvious what. Any ideas? Cheers, Stephen

I would like to grant anonymous the ability to edit/add a zwiki page, but they can't. the docs say: grant the 'Change ZWiki Page' permission; and to allow page creation, grant the 'Add ZWiki Page' permission. but those permission attributes are not present in my installation of .6 It's at http://www.compkarori.co.nz/x.php?/zwiki -- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/index.php Powered by Interbase and Zope

Re: [Zope] : generic adddtmlDocument method need to find extra form data type

The ZPublisher uses ":<type>" suffixes in argument names (and thereby form field names) to convert the (necessarily) string content to the appropiate type. And, of cause, it raises an exception, if this is impossible. If you want do the conversion by yourself, use a different suffix, e.g. "__<type>". Maybe "-<type>" or something in the same spirit will work, too. Dieter

This will change with Python 1.6 expected to be released near the middle of the year. Dieter

Announcing enterlinux.com final public beta
by Nitin Borwankar 21 May '00

21 May '00

enterlinux.com is a Zope and PTK based site. enterlinux.com is another fine production from the folks at codeit.com. * It is a vertical portal for the enterprise user of Linux. * If you are in the market for a Linux Server you might want to check out RaFiQi - the Request for Quotes service that sends simultaneous requests to multiple vendors. * Other interesting areas of the site include the Community area which includes extensions to the PTK. These allow users to contribute content to specific areas of the site and to rate links, documents, news items and user behavior. * The resources section has a Linux Directory of Sites which is the Linux subtree from dmoz.org * There is also a page with the search forsm of some popular Linux and Open Source sites. enterlinux.com requires registration for use of the ecommerce area. I would like to invite all zopistas to run the site through it's paces and send feedback to me nitin(a)borwankar.com, rather than webmaster. Thanks, Nitin Borwankar, Founder enterLinux.com, nitin(a)borwankar.com

ZTopics and Zope2.2.0a1 don't mix
by Bill Anderson 21 May '00

21 May '00

Just thought I would let people know that ZTopics 1.0 and the Zope 2.2.0 alpha (and the CVS version of Zope it appears) do not play nice together. As long as you use standard zope item properties, or non-ZClass objects, it works fine. However, try to use any ZClass items and 'additional' properties, and it fails on an attribute error regardin 'Vocabulary'. Process: o Create catalog, call it 'Catalog' o Give a DTML Document a property of 'TopicName', value of 'Testing' o Add the property to the index and metadata tables in the catalog o Add the DTML Document to the catalog (via find) o Create A ZTopic give it a search for 'Testing' (with quotes!) in the TopicName field o Look at your ZTopic. it should appear fine. o Now create a ZClass, inherit from 'ZCatalog: CatalogAware' o Give it an index_html method to see something when you look at it (optional) o Give it a propertysheet, and a property 'TopicName' o Create an instance of your ZClass, make sure it has 'Testing' as the value for TopicName. o Now look at your ZTopic. All will not be well; it will gripe about the Vocabulary. o Now change the query to meta_type, and for whatever your ZClass' metatype is Now look at your ZTopic folder, all should be well. If anyone has a fix, I would appreciate it (and am sure Amos would accept a patch, I am looking into that part of it myself, but have gotten a bit turned around and may have to shelve it for the night :-( ).

Calling External Method...
by Eric L. Walstad 21 May '00

21 May '00

I am trying to invoke a C++ program from an external method. Platform is Linux. The C++ program returns HTML. Note that the Python function is working properly from the Python command line; That is, ExecCGI.xCGI("./websim") outputs all the expected html. I have placed the C++ program in the same folder as the ExecCGI module. The C++ program works from apache: here's an example of the program's output, which is what I'm trying to get into Zope: http://63.203.42.146/cgi-bin/websim ExecCGI module: import sys, os, string def xCGI( cmdLine ): """ Run an external command and return its standard output as a string. """ f = os.popen( cmdLine ) lines = f.readlines() status = f.close() if status: raise "CGI returned error: %d" % status[1] return string.join( lines ) External Method that calls the C++ program: Id ExecCGI Title Test Function name xCGI Python module file (without suffix) ExecCGI DTML Method that calls the External Method: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <dtml-let cmdLine="'./websim'"> <dtml-var "ExecCGI(cmdLine)"> </dtml-let> <dtml-var standard_html_footer> Traceback: Traceback (innermost last): File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: TestWS) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: TestWS) File /usr/local/Zope/lib/python/OFS/DTMLMethod.py, line 150, in __call__ (Object: TestWS) File /usr/local/Zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: TestWS) File /usr/local/Zope/lib/python/DocumentTemplate/DT_Let.py, line 145, in render (Object: cmdLine="'./websim'") File /usr/local/Zope/lib/python/DocumentTemplate/DT_Util.py, line 335, in eval (Object: ExecCGI(cmdLine)) (Info: ExecCGI) File <string>, line 0, in ?

I think it was John Cleese (as Robin Hood) in Time Bandits, who said it best (upon receiving a bountiful treasure in contribution to the cause) when he stated, "Thank you very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, much."
