Unique Identifiers for Zope Objects
by Michael Abbott 26 Jun '00

26 Jun '00

I'm looking for an internal globally unique identifier for objects in my Zope store. I know that I can use id=object.absolute_url() to create an identifier and then <something>.resolve_url(id) to recover the object from the identifier -- but I have two problems with this API: 1. The URL is not really a global identifier, as resolving it seems to depend on the <something> from which I call resolve_url(). In particular, if the id is created when Zope is running normally (as a service), and resolved when running Zope from the command line debugger, the resolve fails. This is not good. 2. The need to locate an object <something> carrying the resolve_url() function is a problem; in particular, I would find it helpful if I could resolve my global identifier from within a __setstate__() method (where I have no access to local Zope variables), so I really want a genuinely global function for resolving my id. Any suggestions, or do I have to dig into the (disagreeable and uncommented) bowels of Zope and write my own? (If this is on the wrong list, please point me to the right one. Thanks.)

Problem with the datatype "lines"
by Anders Holmbech Nielsen 26 Jun '00

26 Jun '00

Hi Zopers, I have found out that when using the datatype "lines" in my own ZClass it won't obey to the locale settings. That means that the words coming from "lines" look like: t/370nk. And therefore they don't get correctly indexed in the database. I'm running Zope 2.1.6 (on both linux and winnt 4.0). Is there an update to this problem or a workaround ?

2.2.0b2 and ZSQL method and Zcatalog
by Bak ＠ kedai 26 Jun '00

26 Jun '00

hi all, i've upgraded my site to 2.2.0b2. done light testing. here's what don't work -ZSQL method. got len() of unsized object. T.J. Mannos (http://zope.nipltd.com/public/lists/zope-archive.nsf/242bb7cc2b2c343d802568…) mentioned that we need to recreate the SQL method from scratch. is there any other ways? anybody else with this problem? also tried deleting, renaming the ZSQL method, but got the same error with this trace back. FYI, the ZSQL method icon is a folder instead of that green object.

Zope 2.2b2 security conundrum

I am playing with ZDP-Tools which are ZClassed based. When I try to add a new object I get security failure. <H2>Zope Error</H2> <P>Zope has encountered an error while publishing this resource. </P> <P><STRONG>Unauthorized</STRONG></P> You are not authorized to access <em>manage_editProperties</em>. <!-- Traceback (innermost last): File D:\PROGRA~1\Zope22\lib\python\ZPublisher\Publish.py, line 222, in publish_module File D:\PROGRA~1\Zope22\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\PROGRA~1\Zope22\lib\python\ZPublisher\Publish.py, line 171, in publish File D:\PROGRA~1\Zope22\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: FAQQuestionClass_add) File D:\PROGRA~1\Zope22\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: FAQQuestionClass_add) File D:\PROGRA~1\Zope22\lib\python\OFS\DTMLMethod.py, line 168, in __call__ (Object: FAQQuestionClass_add) File D:\PROGRA~1\Zope22\lib\python\DocumentTemplate\DT_String.py, line 500, in __call__ (Object: FAQQuestionClass_add) File D:\PROGRA~1\Zope22\lib\python\DocumentTemplate\DT_With.py, line 146, in render (Object: FAQQuestionClass.createInObjectManager(REQUEST['id'], REQUEST)) File D:\PROGRA~1\Zope22\lib\python\OFS\DTMLMethod.py, line 164, in __call__ (Object: DocumentFolderClass_add_fragment_exec) File D:\PROGRA~1\Zope22\lib\python\DocumentTemplate\DT_String.py, line 500, in __call__ (Object: DocumentFolderClass_add_fragment_exec) File D:\PROGRA~1\Zope22\lib\python\DocumentTemplate\DT_Util.py, line 339, in eval (Object: propertysheets.Info.manage_editProperties(REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

The user I am using doesn't have Manager privlidges but has permission to add this object. I get the add form however when I try to submit the above occurs. I think this might have something to do with the ownership of FAQQuestionClass_add. However I can't see who owns FAQQuestionClass_add. How is the new security model supposed to work with ZClasses and how do I get round this problem so I can give a user the ability to add a new object.

geting the type of an object from within dtml ???
by Thierry Nabeth 26 Jun '00

26 Jun '00

Hello, I have unsuccessifully been trying to figure out ou to get the type of an object from withing html. for instance: <dtml-var meta_type> does not return the correct type. Python is supposed to have a function type(object) that return the type, but I was not able to find a way to call it. (and I would rather prefere not to have to define an external function.). My problem seems to have to do with the Zope namespace (which model I believe is a real pain in the ass :-((((). Any suggestion, ideas ? Thanks Thierry Nabeth, INSEAD CALT http://www.insead.fr/CALT/

I'd like to disable tracebacks from showing up in Zope exceptions (especially on 404s). I know zope.org does this; how can I? Is there a flag I can set somewhere? -- Matt Behrens <matt(a)zigg.com> Owner/Administrator, zigg.com

DTML syntax' not OO?
by Coleman, Bryan 26 Jun '00

26 Jun '00

DTML syntax' not OO? Coming from python trying to learn DTML is very awkward. It seems that there is a different way of doing everything and this has been very frustrating. Is there an underlying theme to the syntax I am not picking up on or was this not a concern for creating the language. The short hand for variables is an example, because it is so different from the long hand method. The python tags are a little better but the documentation on them is a little sketchy. The right editor would be able to use them just as easily as the <DTML> style. - Bryan Patrick Coleman Questcon Technologies (336)273-2428 bcoleman(a)questcon.com
