Can anyone help me sort the following by id in a python script? for object in context.objectValues(['Folder', 'DTML Document','ZipFolder','File','Image']): Import of sequence is not authorised in my python scripts, I am presuming (probably wrongly) that sequence is needed for sort. Regards Garry

Multiple zope instances using the same storage
by Mark Gibson 08 Dec '08

08 Dec '08

I have an unusual setup. I have 4 distinct Zope instances (4 seperate Data.fs'). Each Data.fs is identical - Data is kept in a RDBMS. I have a product I need to install that stores data in the ZODB. This data is stored in one folder. Now, I *think* I can simply mount this folder in each ZODB and serve the storage through a ZEO server - however I've never done this setup, so I want to make sure this makes sense and I'm not overlooking potential problems. This is a legacy setup that I'm not responsible for, so I'm trying to keep my footprint in this setup as small as possible. Using Zope 2.7.9. Thanks, Mark

pb with attach file
by blondelle＠abes.fr 08 Dec '08

Hello, Few months ago, I send my problem with attach file with Zope 2.6 and higher. How I have no solution, I send again my problem which is described after -------- Thanks to help me Frederique --------------- I have created a zclass with zfile as basic class. With this class, users could, via a web form, send an attached file if they want. With zope 2.5 (my previous version) if users don't attach a file, there is no problem with zope 2.10, if there is no file attached, I have an error message : 'file not specified". It seems that attach file is mandatory. Here, the complete message from the events log : 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 OFS.DTMLMethod, line 144, in __call__ - <DTMLMethod at /assistance/do_add> - URL: http://assistance.abes.fr/do_add/manage_main - Physical Path: /assistance/do_add Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_With, line 76, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: _ Module <string>, line 1, in <expression> Module OFS.DTMLMethod, line 137, in __call__ - <DTMLMethod at /assistance/Quest_susvp_add> - URL: http://assistance.abes.fr/Quest_susvp_add/manage_main - Physical Path: /assistance/Quest_susvp_add Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_With, line 61, in render Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: REQUEST Module <string>, line 1, in <expression> Module ZClasses.ZClass, line 454, in createInObjectManager Module ZClasses.ZClass, line 485, in fromRequest Module ZPublisher.mapply, line 89, in mapply Module OFS.Image, line 120, in __init__ Module OFS.Image, line 501, in _read_data ValueError: File not specified

Guestbook example app stops working
by Bernard Devlin 06 Dec '08

06 Dec '08

Hi, I'm looking at the idea of using Zope again (a lot seems to have changed..) I'm using Zope 2.11.1, and whilst trying to remind myself of the basic machinery of Zope, I imported the Example apps, and started to fiddle around with the Guestbook example. However, after saving the index_html object of the Guestbook, Zope would no longer find any entries to display. To check it was simply the act of saving index_html that broke the Guestbook, I deleted the Examples folder and re-imported it. With a fresh Examples folder Guestbook worked; simply saving it (without even typing in the textarea) would break the Guestbook. On initial import it shows a single Guestbook entry by "Amos", but after saving index_html, it reports that the Guestbook is empty. No changes were made to the 'getEntries' script, and the Entries folder still has the entry by "Amos". I can't see any reason why that would be, and hoped someone else could explain what the problem is.

Write a bug report, attach the patch and for a quicker response inform a "Five" maintainer about the "bug+solution". I am not sure however, that this will be sufficient: "Zope 2.9" is no longer an actively maintained version; maybe the maintainers think there are more important tasks that to fix problems with older versions. -- Dieter

Anyone know of a tool to restore/cleanup/reset security/role settings?
by Ross Patterson 01 Dec '08

01 Dec '08

Does anyone know of an existing tool for restoring all security settings/rolemaps from the ground up? Obviously I can use rolemap.xml where applicable and update workflow security. I want to first restore the Zope root to code defaults and restore the whole hierarchy to just acquire. I'm going to write something myself if not, but I thought I'd see if there was anything out there. Ross
