Why 'unbound method' error?
by Warnes, Gregory R 27 Jul '02

27 Jul '02

I've just modified a python product and I've started getting an error that doesn't make sense to me. Here's the error message: Error Type: TypeError Error Value: unbound method connect() must be called with instance as first argument [...] File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSessionDA.py, line 213, in putFile (Object: RSession) File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSOAP/localRSOAPConnection.py, line 124, in uploadFile (Object: RSession) File /Volumes/app/appman/lib/zope/Zope-2.5.1-solaris-2.6-sparc/Products/RSessionD A/RSOAP/localRSOAPConnection.py, line 49, in connect (Object: RSession) TypeError: (see above) and the 'offending' code: class RSession(localRSOAPConnection, SimpleItem): '''Connection object to the R Kernel''' # no connect method defined here ... # .... class localRSOAPConnection(RSOAPConnection): def connect(self): flag = RSOAPConnection.connect(self) if flag: self.__checklocal() return flag .... The localRSOAPConnection code works just fine in standalone Python. In Zope the localRSOAPConnection is extended by RSession with methods that are Zope-aware. My question is why is the call to 'connect' failing in Zope? I am passing a valid instance with the self argument...

Apache, Zope, and SSL with dynamic IP?
by Jordi YC 27 Jul '02

27 Jul '02

Hi, I wonder if anyone can point me to a howto to use Apache (https) as the front-end for a Zope server using a dynamic IP (cable) I have looked through the howto docs at zope and specially http://www.zope.org/Members/unfo/apache_zserver_ssl, but it seems that virtual hosts is not an option with ssl (?) Any suggestions or conf file examples? TIA, J

A Zope Cookbook is what I had in mind (although you coined the phrase far better). Note, however, that the ZopeLabs has bits and pieces (and not all of the pieces). There are many basic things that are not covered in ZopeLabs (probably because they are so elementary) that should be covered for newbies. Ron

creating instances of ZDiscussions programatically
by Dennis Allison 26 Jul '02

26 Jul '02

I am having difficulty creating instances of ZDiscussions programatically. Creating instances from the ZMI works fine. But creating instances as an action and having it work automagically has proven to be a problem. Any help would be much appreciated.

RE: [Zope] List of safe libraries
by abg＠comco-inc.com 26 Jul '02

26 Jul '02

Actually, I was wondering if there is a "Master List" of libraries and modules that one is authorized to import into a python script object. -----Original Message----- From: Joel Burton [mailto:joel@joelburton.com] Sent: Friday, July 26, 2002 11:28 AM To: Aaron Gillette Subject: RE: [Zope] List of safe libraries It's a little fuzzy... what constitutes safe? Even without any additional libraries, a clever coder can hang a Zope thread using just PythonScripts. Regular expressions, for instance, are safe in that they won't let you write to the filesystem or do other serious damage, but you can easily write a regex that will never finish, hanging that Zope thread. Can you be more specific about who will be allowed to write these scripts? Semi-trusted internal users? Complete strangers? - J. -- Joel BURTON | joel@joelburton | www.joelburton.com | aim:wjoelburton Information Technology & Knowledge Management Consultant > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of > abg(a)comco-inc.com > Sent: Friday, July 26, 2002 12:29 PM > To: zope(a)zope.org > Subject: [Zope] List of safe libraries > > > Does anyone keep a list of libraries that are safe for import into python > script objects? > > Thanks, > > Aaron Gillette > abg(a)comco-inc.com > > Comco, Inc. > The Source for Data Pros WorldWide. > Specializing in large-format tape drives (3480, 3490, 3490e, 3590 & > 9-track), data translation services and data management software. > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

Deinstalling LeakFinder
by Charlie Reiman 26 Jul '02

26 Jul '02

I installed LeakFinder a few weeks ago then removed it soon after. LeakFinder does not show up in the Product listing anymore, but it still throws an exception at startup 2002-07-26T16:36:16 PROBLEM(100) ZODB Could not import class 'LeakFinder' from module 'Products.LeakFinder.LeakFinder' And it still shows up (with a broken icon) under the control panel, with the caption "This object from the LeakFinder product is broken!" So how do I remove this last vestige of LeakFinder?

AttributeError: getOwner
by THerp＠apriori.de 26 Jul '02

26 Jul '02

Hi, I have a strange problem with my ZClass. We have built a layout system, where pages (a ZClass) contain components (another ZClass) of different types (header, text...); the code for adding, changing and displaying the components is stored in templates (which are DTML Methods and _not_ part of the component object but stored in an ordinary, acquisited folder). However, since I condensed the code to simply tell each component to render itself, I get an error when I try to modify the component via the interface. I tracked it down to common.manage_changeProperties, which throws an AttributeError, error value: getOwner. Base classes of the component ZClass: ZObject, CatalogAwareBase, ZObjectManager Python method 'render': ## Script (Python) "render" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title=gibt das gerenderte Template zurück ## from Products.PythonScripts.standard import DTML request = context.REQUEST response = request.RESPONSE print '' % \ container.title_and_id() the_template = container.getTemplate() myDTML = DTML(the_template.document_src()) request.componentTree.append(container) print myDTML(context, request, response) request.componentTree.pop() print '' % \ container.title_and_id() return printed ## The End Method getTemplate: ## Script (Python) "getTemplate" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title=gibt das Template-Objekt zurück ## # das Template-Objekt zurückgeben (die DTML-Methode): return context.aq_parent.components_[container.template] ## The End Any ideas? Thanks a lot, Tobias . . . . . . . . . . . . . . . . . . . . . . . . .

populating form values from a sql method
by Erik Myllymaki 26 Jul '02

26 Jul '02

A users starts with a blank form. She fills in some field values, slects some values form pull-downs. Submits the form which adds a new record into a database. Later, the user wants to update that infomation (or input a NEW record but use that info as a template). What is the cleanest way to pull up that form with the fields already containing the data from that database record? Is there a product that is close to this? Formulator? TIA
