zope & document management systems
by mark dufour 04 Nov '02

04 Nov '02

Hello all, Some people at my university have developed a free, LGPL'ed, modular Document Management System. About a year ago, because of some other project, they were so disgusted by the licensing scheme of Documentum that they decided they would try and create a free alternative. After a few months of work by several people, it's starting to look very good, and they are thinking about doing a first release within the next few months. I am thinking about writing a Zope plugin/extension for this Document Management System (excuse my terminology, I'm new to Zope,) that would enable its contents to be accessed/searched through uniformly with other content, using Zope's generic framework. But as I'm rather new to Zope, it's difficult to see what would be the most natural way of accomplishing this. Any suggestions would be greatly appreciated. Specifically, the following would be important features: -Users can upload documents and provide metadata which are subsequently copied into the DMS. -The metadata and document contents are indexed in the generic way, I believe it is called a ZCatalog :-) I see that a product called 'ExternalFile' provides an abstraction for accessing files external to Zope. Would it be possible to enhance this product for my purposes? Or would it be more natural to use some other product as a starting point? As a final question, does anyone know of an earlier attempt at creating something similar, but for another DMS? Any help in this is greatly appreciated. Thanks, -- Mark Dufour.

I'm getting this error since I upgraded to Zope 2.6 (from 2.3). Formerly, everything was going ok. What can be the problem??: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PythonScripts.PythonScript, line 315, in _exec Module Script (Python), line 32, in marcaResultados - <PythonScript at /jmruiz/1X2/marcaResultados> - Line 32 UnicodeError: ASCII encoding error: ordinal not in range(128) _______________________________________________________________ Yahoo!

copy large directories in ZMI possible? Howto?
by Florian Konnertz 04 Nov '02

04 Nov '02

Hi zopies, When i try to copy many objects via the ZMI there is sometimes the 'Paste'-button missing in the/any destination folder. This is/was a known bug, solved up from 2.3. - See: http://www.zope.org/Products/Zope/2.3.1/CHANGES.txt - Zope 2.3.0 - Bugs Fixed - Fixed a bug in the management interface which caused the "Paste" button to not show up after a copy or cut operation on the first showing of manage_main. But it still occurs in my Zope, in 2.4.(?); 2.5.0; 2.5.1 and in 2.6.0 Does anybody know something about it and how to solve the prob? I want to copy all my zwiki pages (about 450) in a new zwiki instance and i really don't want to spend an afternoon to click all of them manually!!

Undo error

I always have a trouble to undo something. Zope: 2.5, not updated OS: Linux SuSE 8.0 Pro Session is on ZODB, not in temp folder. Anybody know what this error means and how to avoid this?

Writing a Script To Thumbnail Photos
by beno 03 Nov '02

03 Nov '02

Hi; I know it's easy to write a script that proportionally changes the width and height of jpegs, but can I programmatically change the size of the image at the same time? In other words, in Photoshop I can make thumbnails that are considerably lighter than the original photos. Can I do the same programmatically? Is that what PIL is for? If so, any heads up on available scripts? TIA, beno

Programmatic creation/update of ZSQL methods
by Charlie Reiman 02 Nov '02

02 Nov '02

I've got about 60 or so ZSQL methods that I maintain in my Zope. Actually, I don't maintain them: our Oracle expert changes them then I have to translate them into DTML, split them into little chunks, and upload them into zope. Since I'm terribly lazy I've automated the DTMLification and the splitting. But the third step of uploading the ZSQL bodies is tricker. Currently I'm uploading them via FTP but this requires that the methods already exist (due to a lack of object type magic). I've also tried using xmlrpc but manage_addZSQLMethod does not seem to live on Folder so I'm not sure how I can call it. So my question is: How can I create ZSQL methods from an external program (a python script in this case)? I've got the body, the id, the destination, the connection id, the parameters... everything but a clue. I know about PUT_factory but I didn't have much luck with that either.

New zope.org development
by Guido van Rossum 01 Nov '02

01 Nov '02

There have been complaints about zope.org. The complaints include things like "the design is ugly", "the navigation is difficult", "it's too slow", and "search results are not useful." For a long time there have been plans to convert the site to the current version of Zope using CMF, and various false starts have been made, but so far the site is still running software that's best described "FrakenZope 2.3"... I opened my big mouth, and now I'm responsible for fixing this. :-) Actually, a new plan was already in place, and all I have to do is coach its execution. Zope Corporation has retained a highly skilled Zope developer, Sidnei da Silva, to do the work. The advantage over Zope Corporation developers doing this (as has been tried in the past) is that Sidnei isn't likely to be pre-empted by higher-priority customer work: for him, this *is* customer work, the customer being Zope Corporation. At the same time, because Sidnei is being paid, the expectation is that the plan will be carried out at a steady pace, as opposed to simply "letting the community sort it out." Sidnei's plan includes the following pieces: - use Zope 2.6 with CMF 1.3 for the new site - use a new skin design, the winner of the zope.org contest - use the new ZCTextIndex search engine - migrate all existing users and as much content as practical to the new site (There's more, but we'd be getting into detail territory.) The project goals include minimizing the amount of new code and content to be created, in order to minimize the risks of failure. We also strive to make future maintenance of the site simpler, both at the sysadmin level (process and resource control) and at the webmaster level (content control). All these goals are designed to make sure that the site can be kept current once the upgrade is in place. Time-wise, Sidnei expects a preview version of the new site to go up as new.zope.org within a month, and the final version to go live (replacing the old www.zope.org) within 2-3 months after that. Sidnei expects to be asking community help with some tasks; he'll post about this himself. In addition, we're also hoping to hire Sidnei as part-time webmaster for zope.org, starting next week. Having a steady webmaster will help the site stay accurate and up-to-date. --Guido van Rossum (home page: http://www.python.org/~guido/)

I saw that too in my research. But I am not looking to authenticate users. The validation I seek is that which is built into Formulator but doesn't seem to work with TAL. Of much_greater_importance is getting the fields to render. In other words, after the visitor has filled out the form, I need to be able to call and use those fields. For example, how do I thank the visitor by name using TAL?

Meta Tags
by Niclas Kuehne 31 Oct '02

Does anyone know of a way to evaluate the meta tags in a HTML/DTML-Document within Zope? I would like to be able to use for example the value of the Metatag "Keywords" within DTML-Scripts. Please email your replies to nk(a)nkmail.com Thanks alot! Nic
