python script containing userid and ip address help
by Dean Hale 27 Oct '04

27 Oct '04

Hi We are attempting to create a python script using md5 to enable SSO between our systems. We have a simple python script import md5 key_string = "UIDPassPhraseIPno" print md5.new( key_string ).hexdigest() which returns 1bee32f99b3f6adba13c450024ab126f However we need three fields to be pulled automatically once the user logs in UID PassPhrase (for example onceuponatime) IP number currently using LDAPUserFolder as the authentication source I've figured out these uid python:member.getProperty('uid'); ip request/REMOTE_ADDR which we use in portlets etc but not sure how to use them within the script above. we can use links manually as below, however we have 1000's of users and i haven't a clue how to achieve above within python. <a href="http://url?action=sso:portal&userid=myid&session=804ab421d396cf8465…">Dean's test from his pc</a> Currently using LDAPUserFolder, Plone 2, Zope27 on SUSE. Probably as clear as mud, but any advice appreciated. thanks dean

Webdav
by John Poltorak 27 Oct '04

27 Oct '04

Is Zope enabled for Webdav by default or does something specific need to be set? As far as a Webdav enabled client, will recent versions of Mozilla (1.73) be OK for using Webdav and how would I get them into Webdav mode? -- John

Hi, I'm a newbie. I' ve this problem. I've a Zope 2.7.2 installation on a windows machine, a zope instance with some products installed (ZODBC etc.) and an application. I have to upgrade zope to 2.7.3: how can I install the new version of Zope? I have to uninstall the old version before installing the new? How can I keep my previous instance? I've found some indications on the web and in this list, but they aren't so clear to me. Please help me!! Piergiorgio

Operator overriding not working with Zope class.
by Etienne Labuschagne 27 Oct '04

27 Oct '04

I have two classes: class Person: .... class ZPerson(Person, ZopeClasses....): .... in Person 'n override __gt__, __lt__, and some others. >>> p1 = Person() >>> p2 = Person() >>> p1.age = 20 >>> p2.age = 30 >>> p2 > p1 True this doesn't work for the derived Zope class: >>> p1 = ZPerson() #ok, I create this in the "proper" zope way and #later retrieve it, but you get the idea >>> p2 = ZPerson() >>> p1.age = 20 >>> p2.age = 30 >>> p2 > p1 False >>> p2.__gt__(p1) True For some reason my __gt__ is not used when using the > operator. If called explicitly, it works properly. Any ideas? Etienne

Product security and OFS.CopySupport
by Michael R. Schwab 27 Oct '04

27 Oct '04

Hi, I've encountered problems when adding security declarations to a Zope folderish object product on Zope 2.7.2/Python 2.3.4/RH Linux 9.0. My folderish object 'CustomFolder' (see http://files.englesh.org/CustomFolder.tgz for source) has permissions on its methods. For example, I'm declaring: security.declarePublic('index_html') index_html = PageTemplateFile( os.path.join('zpt', 'default_index_html'), globals()) I then initialize the permissions for my object calling: InitializeClass(CustomFolder) When I instantiate a 'CustomFolder', I can add new sub objects. I am, however, unable to paste or rename objects within the 'CustomFolder' instance. I've been able to trace the error to the call to _verifyObjectPaste (line 352) in OFS.CopySupport. It appears that _verifyObjectPaste fails on the call to self.restrictedTraverse(method_name). The comments following the call seem to indicate that an Unauthorized exception is thrown if the factory method by name cannot be obtained. Is there something that I am missing in my security declarations for 'CustomFolder' or is this a bug in OFS.CopySupport or OFS.Traversable? I've goggled on this but the results I have found have not fixed the problem I am seeing. Thanks, Michael -- Michael R. Schwab All those who believe in psychokinesis, raise my hand.

Error messages from external methods
by Joe Goldthwaite 26 Oct '04

26 Oct '04

Something strange happened after I upgraded to Zope 2.7.2. If there was a run time error in my external method, it used to return the module and line number as part of the error message. Now it just returns an error description without the line information. Here's an example; Site Error An error was encountered while publishing this resource. Error Type: KeyError Error Value: 'P' Troubleshooting Suggestions * This resource may be trying to reference a nonexistent object or variable 'P'. * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the error log. If the error persists please contact the site maintainer. Thank you for your patience. I upgraded to Zope 2.7.3 in the hope that the line numbers would start working again but no luck. Is there an option that controls this? If not, is there a fix that will get the line numbers working again? Now that I think about it, it may be related to some changes I made trying to get the Wing debugger working with Zope. I'll follow up on that thought. If anyone has any insite to this problem, I'd appreciated it. Thanks, Joe Goldthwaite

zope ftp error
by Foo Chee Yuan 26 Oct '04

26 Oct '04

Hi, I am a Zope/Plone newbie and have encountered these strange FTP problems while uploading to Members home directory. 1) Sometimes the uploads are unsuccessful with the server returning "426 Error writing file" message 2) Sometimes the uploads are successful but when I use Plone web interface to log-in the files are not not shown. These problems happens to files with varying sizes and extensions and there is no regular pattern that I can decipher. I tried searching for the Zope Ftp patch that allows the ftp server to return more meaningful messages but couldn't find it in Zope.org. Can someone please give me some pointers as to how to solve this problem or give me the exact url to the patch? Thanks and regards Chee yuan
