grufspaces, scripts and inherited permissions
by sguglia＠arrows.it 29 Feb '08

29 Feb '08

Hello everybody, I created a group member and a group folder (using grufspaces), from where I run a python script. The result of this script is a n number of brain objects (indexed_file) indexed in portal_catalog. All object are correctly indexed, so I can search contents, but as a groupmember only. the question is: how can I modify (from the script) permissions of the brains objects in order to get them searchable from anybody? the main part of my script: for pub in context.query_05(idx_value=idx_value): object = '/query_06/' + pub.id + '/indexed_file' my_catalog.catalog_object(pub, object) thanks! Stefano

HI all, I think about altering of ZCacheable_manage to show all cached variants of cache keys ( Names from the DTML namespace) with their times and invalidation of selected single variant. Do somebody have this kind of thing realised? Many thanks, J. Lukesh

Acquisition / proxying object
by Joerg Baach 27 Feb '08

27 Feb '08

Hi *, I am trying to have a folderish object that acquires from a user object (ldapuserfolder). It should have its own properties and contents, but fall back to the ones of the ldap user. I have created an object, extending Folder, and it behaves nicely in zopectl debug. When I try to access it through e.g. a python script I get an: Error Type: Unauthorized Error Value: Unable to find __roles__ in the container and the container is not wrapped. Access to 'dn' of test, acquired through (LDAPProxy at /testfolder/ldapproxy), denied. I am sure its my lack of understanding of acquisition. I am trying to bascially put ldap user object 'on top' of the aquisition line (with the ldapproxy at the bottom), but obviously failing in doing so. Any ideas?

Zope 2.11.x and 2.10.x
by baiewola 27 Feb '08

27 Feb '08

I want to install Zope 2.10.5 or 2.11.0-al on Mac OSX 10.5.2, which comes pre-installed with Python 2.5.1. Install docs for both say they don't work with 2.5. Does that mean they don't work with anything 2.5 and above, or only version 2.5 specifically? Has anyone been able to install either of these Zopes with Python 2.5.1? Thanks! ____________________________________________________________________________________ Looking for last minute shopping deals? Find them fast with Yahoo!

Static adquirable resource
by Garito 27 Feb '08

27 Feb '08

Hi! Some weeks ago Tres point us how to declare static resources with five You could create a configure.zcml file for your product and put some code like these: <configure xmlns:browser="http://namespaces.zope.org/browser"> <browser:page for="*" name="ZSmanage" template="recursos/ZSmanage.pt" permission="zope2.Public" /> </configure> and magically you could use it as: http://server:port/ZSmanage But if you try to use ZSmanage as an acquired object you could Can I do something at this respect? I would like to use ZSmanage in a different context, can I? Thanks! -- Mis Cosas http://blogs.sistes.net/Garito Zope Smart Manager http://blogs.sistes.net/Garito/670

Zope 3 and Rails - a pragmatic and agile comparation (put the hype aside)
by Marcelo de Moraes Serpa 26 Feb '08

26 Feb '08

Hello, I come from a Rails background, been working with Rails for about 1 year and a half, it has been a great experience but my last project required me to use Plone as a base framework for the portal/application. I then started deeply studying Plone 3. Bought and read Martin's excellent book Professional Plone Development from cover to cover. Struggled with Zope concepts but almost always could grasp them by reading the other books from the Zope/Plone bookshelf or online articles/tutorials. It has been 3 months already. The project is almost done and I've learned to like Plone and Zope 2. However, what attracted me the most was Zope 3 and its elegant concepts and OOP patterns and this led me to question some things: * The differences in the approaches taken by Rails and Zope 3 to provide developer productivity, scalability and application maintability. Rails is productive, no doubt regarding this. However, I feel that it restricts me in the OOP side of things, hiding much of the OOP patterns from the developer. The "put there it will just work" philosophy often makes it hard (at least harder than if it were being implemented on Zope 3) to make more advanced, complex and specific things. I do believe in the agile methodology and I always follow it whatever I am working with Java, python, C or Rails. Rails just happens to be an out-of-the-box solution that has attract millions of developers becouse of its magic promises and easy learning-curve. I feel however, that Zope 3 with its Component Architecture is much more elegant and can be as productive as Rails AND provide better application scalability and maintability than Rails if you know what you are doing. I can't speak for Zope 2 though :) What do you think? Would you mind sharing your experiences and ideas regarding this subject? Cheers, Marcelo.

Re: 2.10 and ZClasses

I understand and appreciate your responses. Finally got some things straightened out and after changing DA settings to point to real database servers (instead of localhost), and commenting things out that were calling unneeded parts, I am able to get our site up (on some pages) with yesterdays news stored in the Data.fs. I am able to view an actual news ZClass objects with our site header and footer wrapped around it. Not bad. That shows they do work. Long way to go but it's a start But, on the page that does the catalog lookup of the day's news stories, it is a blank page. No errors in the error_log. But if I go to the ArchiveCatalog (our name for our Catalog) and click on the Catalog tab in the ZMI, I get this error: Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module App.special_dtml, line 178, in _exec Module DocumentTemplate.DT_Let, line 76, in render Module DocumentTemplate.DT_In, line 584, in renderwb Module Products.ZCatalog.Lazy, line 144, in __getitem__ IndexError: list index out of range All the other tabs work.

2.10 and ZClasses
by Allen Schmidt Sr. 26 Feb '08

26 Feb '08

We are still running 2.7.5 but really want to upgrade. Changes.txt in 2.10.5 state ZClasses are deprecated. CAN they still be used?? Not at all or just not recommended and why? What is the highest version we can safely upgrade to then? Thanks Allen

zcatalog, brains & keywordIndex
by Stefano Guglia 26 Feb '08

26 Feb '08

Hello everybody.. I have to index some data from a mysql query recordset and all works OK but..I added a keywordIndex to store (with the same url) multiple values related to the above recordset. It seems I cannot use brains (query results are strings). Probably a newbie question, but I really do not know how to update a keywordIndex starting from a list..Any help (+sample code pls :-)) ? Thanks, Stefano.
