broken objects?
by Jürgen Herrmann 24 Mar '05

24 Mar '05

hi! after restarting zope i get broken objects, this seems to happen to my own extension classes only... the error msg is: "This object is broken because the unknown product that created it is no longer installed or is installed incorrectly. Please contact the product maintainer for assistance. Note that the data associated with this product has not been lost, and will be accessible again if the product is reinstalled." this raises a 'not found' with no further info in the traceback. the product seems to be installed fine though. as long as i don't restart my zope instance everything is fine, means i can reload products, update code, etc... anybody got some hints where i should start looking, googling for the error only brought back some mailinglist entries way back from ~2000... regards, juergen herrmann _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Juergen Herrmann Weiherweg 10, 93051 Regensburg, Germany Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 ICQ: 27139974 - IRC: #XLhost@quakenet WEB: http://www.XLhost.de

Re: [Zope] zForum problem
by Cliff Ford 24 Mar '05

Forgot to cc the list in the last reply. Line 142 of zForum.py says: CookieCrumbler.manage_addCC('cookie_authentication') and the error message is saying that it can't find manage_addCC in CookieCrumbler (I have taken out the rest of the Error log from this reply because it contained a plain text database connection string). Check that your Add dropdown list has Cookie Crumbler (Standalone) in its list and that the Zope user has read/write access to the CookieCrumbler and zForum folders. I have a test zForum installed and it just worked! If I create another with a dud database connection string I get a database error when trying to View (the installation appeared to work OK).

zForum problem
by burley＠zonnet.nl 24 Mar '05

24 Mar '05

I've problems getting the zForum product working. When I try to create azForum instance somewhere in my Zope site, I invariably obtain the errormessage: """ Site ErrorAn error was encountered while publishing this resource. Error Type: AttributeError Error Value: manage_addCC """ Looking for a solution on the internet, the closest I could get was asdescribed in http://www.pcfltd.co.uk/docs/zforum.html (which is aboutinstallation on a Windows machine; I'm working on Linux box). In the directory where I want to create the zForum: 1) I do have a database connection which is open en tested (works). 2) I do have a CookieCrumbler instance (which I'm not sure of whetherit's essential or not...); the CookieCrubler properties are unchanged... (i.e. __ac, __ac_name, __ac_password, etc) 3) In the zForum instance form I use the same connection string asdefined in the database connection. The Site Error message keeps popping up all the time (...sigh). Anyone some idea what's wrong...? -- _____________________________________________________________________ Versatel ADSL Gratis.

XML from external server
by Robert Segall 24 Mar '05

24 Mar '05

Would appreciate your opinion: I have an external web server that replies to a certain request with an XML file, with a well defined structure. My goal is to have Zope pick up this file, and "do stuff" with it: perhaps return the HTML after applying an XSLT, or - ideally - access its contents (or parts of it) from some page template and/or DTML. The XML data (but not structure) may change quite often, independently of Zope, and I'd like these changes to be visible to the Zope clients, so it's not only a matter of storing the XML once. Anybody done anything like it? Hints? Tips? Gotchas? Examples? Products?!? -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-44-920 4904

manage_delObjects()
by Leticia Larrosa 24 Mar '05

24 Mar '05

Hi all: In an python script i put the following code: "container.manage_delObjects([container.exampleFolder.getId()])" where "exampleFolder" is the name of an object of type "Folder" in the "container". This code delete the "exampleFolder" OK. But when I have the name of the "Folder" that i want to delete in a variable and call the "manage_delObjects", example: folderToDelete = "exampleFolder" container.manage_delObjects([container[folderToDelete]]) #or container.manage_delObjects([getattr(container, folderToDelete)]) ---------------------------- I get the following error: Error Type: AttributeError Error Value: __getslice__ ----------------------------- The Traceback: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module Products.PythonScripts.PythonScript, line 323, in _exec Module None, line 18, in update - <PythonScript at /approach/SiccApproach/Configuration/AuthenticationTypes/update> - Line 18 Module OFS.ObjectManager, line 453, in manage_delObjects Module OFS.ObjectManager, line 241, in _getOb AttributeError: __getslice__ ------------------------------- This appears that the "manage_delObjects" expect that somehow a non sequence entered a property expected to be a sequence.? My objetives is delete a object of type "Folder" in the "container" from this Script(Python) I use Zope2.7 Thanks in advance!

Query Keyword Index unexpected behavior
by Vital Lobachevsky 24 Mar '05

24 Mar '05

Hi, all! I'm trying to query a Keyword Index using record attributes. The expression ZCatalog(myindex={'query':['foo','bar'], 'operator':'and'}) should return objects that have both "foo" AND "bar". In my case, no objects with "bar", but with "foo" a lot. The expr above returns ALL objects with "foo". Is it expected behavior? How to get what I really want: the objects with "foo" and "bar", that is None? TIA, -- -tick
