Dear AJ, Thanks, but I still have some problems with creating a Folderish Object product I imported Folder from OFS.Folder but I wasn't able to add any products like File, Folder, Image with in my folderish object. my code looks like this--> class ShpProjectClass(Item, Folder, Persistent, Implicit, CatalogAware): id = 'ShpProject' meta_type = 'ShpProject' manage_options = ( {'label':'Contents', 'action':'manage_main'}, {'label':'Properties', 'action':'manage_editShpProjectForm'}, {'label':'View', 'action':'index_html'}, ) + Item.manage_options def __init__(self, id, projectDesc = 'Test Project'): """ Initialize a ShpProject Object """ self.id = id self.projectDesc = projectDesc def getProjectInfo(self): """ print a ShpProject Object Info """ return 'This project is called: ' + self.id + '. This project is about ' + self.projectName + '.' def edit(self, projectDesc, REQUEST=None): """ edit a ShpProject Object """ self.projectDesc = projectDesc if REQUEST is not None: return self.index_html(self, REQUEST) ##Web Methods index_html = HTMLFile('DTML/index_html', globals()) manage_editShpProjectForm = HTMLFile('DTML/manage_editShpProjectForm', globals()) InitializeClass(ShpProjectClass) what else am I missing? and is using ObjectManager unsave in anyway? ----- Original Message ---- From: Andreas Jung <lists(a)zopyx.com> To: Allen Huang <swapp0(a)yahoo.com>; Zope <zope(a)zope.org> Sent: Friday, March 9, 2007 4:05:16 PM Subject: Re: [Zope] have problem with managing objects within a external product --On 9.

For folderish content you derive from ObjectManager or for being on the safe side from OFS.Folder from OFS.Folder import Folder class MyType(Folder): meta_type= 'MyType' .....

External Methods and Authentication error
by Jonathan 11 Mar '07

11 Mar '07

I have an external method that contains: threadFolder = self.unrestrictedTraverse(topFolder + forumId + '/' + threadId, None) threadFolder.manage_changeProperties({'viewCount': threadFolder.viewCount+1}) When this external method is invoked (via an 'Anonymous' user invoking a dtml method) I get the following authentication error: Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module OFS.DTMLMethod, line 144, in __call__ - <DTMLMethod at /Playwiser/WUI/ViewPublicThread> - URL: http://new.playwiser.com/ViewPublicThread/manage_main - Physical Path: /Playwiser/WUI/ViewPublicThread Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Let, line 75, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: document_id Module <string>, line 1, in <expression> Module Products.ExternalMethod.ExternalMethod, line 232, in __call__ - __traceback_info__: (('ViewPublicThread',), {}, None) Module /apps/Zope-2.9.2/Extensions/playwiser-1.0.py, line 705, in ProcessControl Module <string>, line 1, in ?

Access requires one of the following roles: ['Manager']. Your roles in this context are ['Anonymous']. I was under the impression that code in external methods runs as 'trusted' and does not incur normal Zope security checks. Is this error being generated because the external method was invoked by a DTML method or is there some other factor that I am unaware of? Thanks, Jonathan

SQL Server Network Error
by David VanKirk 10 Mar '07

10 Mar '07

I have Zope and SQL Server setup on the same machine, with no firewall running on that PC, so there is no firewall between the two. Occasionally I will get the following error, upon refreshing the page the error disappears. Error Type: ReplayTransaction Error Value: OperationalError on : ('08S01', 11, '[Microsoft][ODBC SQL Server Driver][Shared Memory]General network error. Check your network documentation.', 6108) I found somewhere that this could be caused by a firewall, but, like I said, there is no firewall between Zope and SQL Server. Can anyone help me fix the problem, or at least explain why it might be happening? I'm using Zope 2.6.4, SQL Server 2000, and I'm using egenix's mxODBC driver. -- David VanKirk

However, IIRC, ZODBC is quite old and could have some problems. I would suggest you to invest a few Euros in mxODBC: I've never tried it but Egenix has a good record of producing good products.

No space left on device
by tonylabarbara＠aol.com 09 Mar '07

09 Mar '07

Hi; I'm moving everything over to a new server because the old server's OS is corrupt. I've d'l'd a 300MB *.zexp file from the old server. (I have to d'l it to my PC over a slow satellite connection, then upload it to the new server because of the corruption.) When I went to install it, I got this error: No space left on device Here's the entire traceback. Is this stating that it's too big for the temporary storage? Is there a way to increase that limit? I suppose I could create a new Data.fs with just this folder, but because of the above-mentioned, it's a nightmare downloading and then uploading it.

CMF 2.1.0-beta released
by Jens Vagelpohl 09 Mar '07

09 Mar '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The CMF developer community is hereby announcing the release of CMF version 2.1.0-beta. The CMF 2.1 series will be used as the foundation for the Plone 3.0 release, which will see its first beta over the next few days as well. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit http://www.zope.org/Products/CMF/CMF-2.1.0-beta. Roadmap and release information can be found at http://www.zope.org/Products/CMF/docs/roadmap. The CMF mailing list can be reached at the zope-cmf(a)zope.org address, to sign up please visit http://mail.zope.org/mailman/listinfo/zope- cmf. Please file bug reports, feature requests or suggestions in the CMF bug collector at http://www.zope.org/Collectors/CMF . What has changed since the last release? IMPORTANT NOTE: If you upgrade an existing CMF instance to CMF 2.1, please see INSTALL.txt for instructions on how to run a separate upgrade script. New Features - CMFCalendar: Zope3 style browser views are now used by default. An additional setup profile allows you to hook up the oldstyle skins and to make customizations TTW. - DirectoryView: Added 'registerDirectory' ZCML directive. Using the old registerDirectory method in __init__.py is now deprecated. See zcml.IRegisterDirectoryDirective for details. - DirectoryView: Added support for non-product packages. This introduces new registry keys. Old registry keys stored in persistent DirectoryView objects are updated on the fly. (http://www.zope.org/Collectors/CMF/467) - Document: Added two new methods for safety belt handling. - setup handlers: Improved properties handler. It now works with properties using a default_charset other than UTF-8. - Merged patches from Martin Aspeli to enable generating events before and after DCWorkflow transitions, and in the 'notify' methods of the workflow tool (http://www.zope.org/Collectors/CMF/461) Bug Fixes - CMFUid.UniqueIdHandlerTool: Touching the internal UID value on a content item will not cause reindexing all indices anymore, only the specific UID index will be touched. (http://www.zope.org/Collectors/CMF/469) - CMFCore.MembershipTool: Fixed inconsistent behavior where member lookup would take all user folders up to the Zope root into account whereas member area creation would not. - CMFCore.MembershipTool/CMFDefault.MembershipTool: when using an object without a __nonzero__ but with a __len__ (ala CMFBTreeFolder) as a member folder, the createMemberArea method would believe there was no members folder if the folder was empty, and so would fail (change "not membersfolder" to "membersfolder is not None") . - CMFDefault.File and CMFDefault.Image: Restored ZMI Cache tab which was lost in CMF 1.6. - CMFCore.DynamicType: Fixed behaviour regarding default view. DynamicType was making it impossible to use a Zope3-style default view for CMF content types. (http://www.zope.org/Collectors/CMF/459) Others - Tool lookup and registration is now done "the Zope 3 way" as utilities. Please see docs/ToolsAreUtilities.txt for some developer notes. - CMFCore utils: Marked 'minimalpath' and 'expandpath' as deprecated. - The CMF now depends on Zope 2.10.2 or higher. jens -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iD8DBQFF8SvFRAx5nvEhZLIRAoMdAKCpDmPch1uLAR6g/3Xq+x3F12w1kgCfZKsa qVpT3k6bRXm6C+dutlylMMk= =94JT -----END PGP SIGNATURE-----

have problem with managing objects within a external product
by Allen Huang 09 Mar '07

09 Mar '07

I made a simple product using python that stores some varibles, but I couldn't make it acts like a folderish, stores objects, and have a content tab page using manage_main like when I use to have when I use internal product. I reviewed the tutorials on how to make internal products and I found the base class modules ObjectManager and PropertySheets under OFS folder but I really ahve no idea how to use them. So it I want my product to act like an internally made product with baseclass ObjectManager, CatalogAware, and use propertysheets to manage my attributes and control what object type I want to store, would importing ObjectManager, PropertySheets, CatalogAware baseclass be enough? ____________________________________________________________________________________ Don't pick lemons.
