ZODB limits
by WebMaster＠solari.it 27 Jan '04

27 Jan '04

I'm developing an intranet document management system with Zope/Plone and I'm concerned about the capabilities of ZODB. The system is going to store many thousands of large files, so the Data.fs is very likely to grow up to tens of GB. I'm wondering if ZODB can handle such amount of data in its standard implementation (using Data.fs). I investigated several alternatives, including ApeLib/Dbtab, but they don't seem to work out of the box with Plone (while thay do in ZMI). Is somebody aware of **fully-tested, real-world** applications with multi-GB storage or, in other words, should I stay with ZODB or search for alternatives? Thanks Alessio Beltrame

by Jonas Meurer 27 Jan '04

27 Jan '04

hello, for some reasons there seem to be significant changes in ZCatalog between Zope 2.5.2 and Zope 2.6.2. In other words, I don't have the vocabulary option at ZCatalog creation in 2.6.2 any longer. what exactly happened and how can i workaround this? bye jonas -- (c) 2004 by Jonas Meurer <meurer(a)know-it.net>

Upgrading ExtFile
by Andreas Tille 27 Jan '04

27 Jan '04

Hello, I upgraded ExtFile / ExtImage from version 1.1.3 to version 1.2 (on a Debian GNU/Linux testing system). The new version works fine for new uploads. But I have an old application which now does not find its stored images any more. Analyzing the error messages I found the problem: 1. If there is a file <Reposit>/image.jpg the new ExtImage is looking for <Reposit>/image1.jpg . 2. If there is a file <Reposit>/image<n>.jpg the new ExtImage is looking for <Reposit>/image<n+1>.jpg . I placed some symlinks into the repository to verify this behaviour for several images. This is also true for thumbnails etc. Any hint what might be wrong here? BTW, the new versin of Extfile now is available at http://zope.org/Members/shh/ExtFile/ It would be reasonable to mention this fact at the place of the old versions ... Kind regards Andreas.

Patching under windows...

Hi List, ...how do I install a Zope patch under Windows. I'm concerned about wearing Google out, although to be honest my patience will be exhausted first...

Dieter Maurer wrote: > A proxy role (read about them in the Zope Book, 2.6 edition). Thank you for pointing this out. If I go into the DTML method I created in the "methods" folder of my ZClass and change the Proxy Role to Manager, it works just like it should! > >1) Is there a way to update only the individual ZClass object in the > >catalog > > The method is "catalog_object" -- it, too, has a well chosen name ;-) I have some questions about this, if the object is already in the catalog and just needs to be updated. Would I still use this method, or would this create an additional object in the database? I found the following python script which mentions how to use the catalog_object method: http://www.zopera.org/Members/Caro07/updatecatalog request = context.REQUEST catalog = context.Catalog myobject = getattr (context, id) catalog.catalog_object (myobject, id) However, when I try using this, I receive an error saying that "global name 'id' is not defined" Do you have any suggestions on how to I might implement this correctly? Thanks! John T.

Re: [Zope] non-persistent publishable objects

Is a publishable class not necessarily the same as a product class, then? You also used a meta_type attribute. Do you know if this is necessary? Furthermore, do you think it is possible to store local roles in my relational tables to feed Zope's security machinery?

From their website: The components that Twisted Spread provides are as follows: * pb: pb is the Perspective Broker.
