When I remember right, the Add box is constructed by "filtered_meta_types". Thus, you must give your ZClass a method with this name (the correct name, if I do not remember right), that returns the correct list. Dieter

A user folder is only allowed to return "Annonymous", if it is the top level user folder. Thus, your "/sms/shtml/statios/acl_users" must return "None" and ZPublisher should ask "/sms/acl_users" which should return "Operator". > Another investigation: I am logged as operator in a new browser and have the > problem, I click on a link for a stationx user but cancel the http > authentication, then the problem disappear. Hmmh, the only difference should be that you no longer have an HTTP authentication. I do not understand this behaviour. > Is there a way to display which object has triggered the authentication, and > which acl_users folder is used?? You can instrument the code in "ZPublisher.BaseRequest.traverse" to output this information. Dieter

client argument to python function calls?
by Randall Kern 27 Nov '00

27 Nov '00

I'm trying to emulate some DTML methods with python code in my (python) product. Let's say I have two Python classes, one named Foo, the other Bar. Something like this: class Foo(Folder.Folder, Persistent, Implicit): meta_type = "Foo" def magic(self, client=None): "magic method!" if client == None: client = self return client.magic_word class Bar(Folder.Folder, Persistent, Implicit): meta_type = "Bar" def __init__(self, id): self.id = id self.magic_word = 'Alacazam!" Now I create a structure like this in Zope: / foo (instance of the Foo class) bar (instance of the Bar class) Now if I goto /bar/foo/magic, I see the magic word. However, I would also like to use /foo/bar/magic, and also receive the magic word. This latter case doesn't work, the magic_word isn't set. In fact, the "client" argument is never anything but None. This is a facet of Zope I still don't quite understand... Thanks, -Randy

Re: [Zope] getattr in Python Method problem

Anyway, there are several Python method implementations around that might be different in the relevant aspects. Personnally, I would expect a bug in "getattr". However, it might also be the case, that "self" is not what we expect (and what it is for external methods: the folder, the object is located in). If you use a new version of Python Methods (now called Python Scripts), then you might try "context" rather than "self". I think, you can use it without the need to pass it as parameter. Dieter

Important! Keep an eye on your management screens folks
by Skip Montanaro 27 Nov '00

27 Nov '00

Folks, My ZServer just mailed me this: Zope has encountered a problem publishing your object. Cannot locate object at: /search/manage This suggests to me that someone was probling our site to see if they could get into Zope and twiddle some bits. I use ZServer, not full-blown Zope, so I have no manage pages. Check to make sure your Zope servers are suitably passworded or that management screens are disabled! -- Skip Montanaro (skip(a)mojam.com) Support the Mojam.com Affiliates Program: http://www.mojam.com/affl/ (847)971-7098

view DTML source
by Anders Eriksson 27 Nov '00

27 Nov '00

Hello zopistas, On the zope.org there is a 'method' called view_source, which lets you see the DTML source of a page. I 'borrowed' this code, by using view_source on itself and got this:  <pre>  </pre>   I then created a DMTL-document called 'view_source' with this content. But when I run, using http://swescout.myip.org/index_html/view_source it I get this traceback: Traceback (innermost last): File D:\SweScout\lib\python\ZPublisher\Publish.py, line 222, in publish_module File D:\SweScout\lib\python\ZPublisher\Publish.py, line 187, in publish File D:\SweScout\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: index_html) File D:\SweScout\lib\python\ZPublisher\Publish.py, line 171, in publish File D:\SweScout\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: view_source) File D:\SweScout\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: view_source) File D:\SweScout\lib\python\OFS\DTMLDocument.py, line 177, in __call__ (Object: view_source) File D:\SweScout\lib\python\DocumentTemplate\DT_String.py, line 528, in __call__ (Object: view_source) File D:\SweScout\lib\python\OFS\DTMLMethod.py, line 168, in __call__ (Object: standard_html_header) File D:\SweScout\lib\python\DocumentTemplate\DT_String.py, line 528, in __call__ (Object: standard_html_header) AttributeError: __call__ This is my data: Zope version: Zope 2.2.2 (binary release, python 1.5.2, win32-x86) Python version: 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] System Platform: win32 Anyone that know why I get this error and how I fix it? -- Best regards, Anders mailto:ame@swipnet.se Science is everything we understand well enough to explain to a computer.

Hi. I trie to install Zope-2.2.2 with mod_pcgi2 and the Apache web server. I follow the steps in the README files, but when I trie to access to the URL http://localhost/pcgi I get the following error message: Zope Error Zope has encountered an error while publishing this resource. Resource not found Sorry, the requested Zope resource does not exist. Check the URL and try again. Troubleshooting Suggestions The URL may be incorrect.
