Date bug
by Brown Fox 20 Feb '01

20 Feb '01

Hello, i'm using Zope 2.3, ZMysqlDA2.0.4, MySQL-python0.3.1 and MySQL latest rev. Create a table with a date, put in it 1970-1-1 and try to read it. You will got this error: Error, exceptions.IOError: [Errno 22] Invalid argument I think that the problem is in the Y2K patch in datetime.py. Someone can confirm? Thanks, Bruno ______________________________________________________________________ Do You Yahoo!? Il tuo indirizzo gratis e per sempre @yahoo.it su http://mail.yahoo.it

newbie batching question
by Chris Cioffi 20 Feb '01

20 Feb '01

Hi all, I'm starting to dig into learning Zope. I read through a tutorial and have been working a bit with the Zope Book and there's where I hit a problem. I'm trying to modify the batching example to create a slideshow. Here's what I've got: <dtml-var standard_html_header> <dtml-in expr="objectValues('Images')" size=1 start=query_start> <p>display for any items found: <dtml-var sequence-item></p> </dtml-in> <dtml-var standard_html_footer> (This is stripped down from the code in Chapter 7.) I've put this in the same folder as the Images and all I get is the header and footer text with a blank body. (I'll get the sorting later...) Any pointers would be welcome. Thanks, Chris PS: I've seen the Photo product on the website however the archive is corrupted everytime I download it...

Not authorised to assign proxy role
by Ng Pheng Siong 20 Feb '01

20 Feb '01

Hi, I'm testing my GuardedFile product on Zope 2.3.0. Here's the blurb on GuardedFile: A GuardedFile is a Zope File that is accessible by proxy only. When a GuardedFile is created, all acquired permissions are unset. A proxy role is created in its container with the sole permission "View". When the GuardedFile is deleted, its associated proxy role is also removed. In all other aspects GuardedFile behaves exactly like a File. Suppose I have the following folder structure: root |- test |- guarded Only "root" has acl_users. I, as a regular user in "root"'s acl_users, create a GuardedFile called "agf" in "guarded"; a proxy role "proxy_for_agf" is also created in "guarded" by the product. The content of "agf" is just some text. I then create a dtml method in "guarded" called "prox" thusly: <dtml-var agf> I next try to assign to "prox" the proxy role "proxy_for_agf". The idea is that "anonymous" can access "agf" only thru "prox". I get the following error: You are not authorized to change prox because you do not have proxy roles. Traceback (innermost last): File /usr/local/home/ngps/pkg/zope230-py2/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/home/ngps/pkg/zope230-py2/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/home/ngps/pkg/zope230-py2/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: prox) File /usr/local/home/ngps/pkg/zope230-py2/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/home/ngps/pkg/zope230-py2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_proxy) File /usr/local/home/ngps/pkg/zope230-py2/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_proxy) File /usr/local/home/ngps/pkg/zope230-py2/lib/python/OFS/DTMLMethod.py, line 351, in manage_proxy (Object: prox) File /usr/local/home/ngps/pkg/zope230-py2/lib/python/OFS/DTMLMethod.py, line 342, in _validateProxy (Object: prox) Forbidden: (see above) This used to work in Zope 2.1.x. I didn't test GuardedFile for 2.2.x. What has changed, and what can I do to achieve what I want? Background: GuardedFile supports ZSmime, a product to generate S/MIME-signed/encrypted messages; ZSmime provides a tag "dtml-smime". The private key required for S/MIME signature generation is stored as a GuardedFile and the dtml method that invokes dtml-smime is assigned the necessary proxy role to access the private key in said GuardedFile. See http://www.post1.com/home/ngps/zsmime for more info. TIA. Cheers. -- Ng Pheng Siong <ngps(a)post1.com> * http://www.post1.com/home/ngps

New Riders to publish The Zope Book
by Michel Pelletier 20 Feb '01

20 Feb '01

New Riders to publish "The Zope Book" As many of you know, Amos Latteier and I have spent the last year working with O'Reilly and Associates writing a book about Zope. Recently, O'Reilly decided not to publish the book. We took the book to a number of different publishers, all of whom showed a lot of interest in publishing it. After lots of discussion and review of our options, we have decided to go with New Riders Publishing. We think is a great choice for us, for Zope, and for the Zope community. New Riders is a great publishing company, and we have been very impressed with their line-up of high quality, open source oriented books. Amos and I are really excited to become NR authors, and to have our works placed alongside other great NR books. One of our main reasons for going with NR was their enthusiasm to publish the book under an open content license. Starting today, *The Zope Book* is licensed under the Open Publication License v1.0 (http://www.opencontent.org/openpub/) with none of the restrictive license options chosen. These new licensing terms means that we can we begin to distribute the book in several different downloadable formats, and that you, the reader, can use the book content in a free and open manner in accordance with OPL guidelines. We will also be providing the book in raw, structured text format from a publicly available CVS archive so that community members can contribute patches directly to the book, and other great documentation projects we will be announcing soon! At this point, it is difficult for us to talk about firm timelines, but we hope to have the book on the shelves by early June. NR is very commited to providing us with extensive editorial resources, and the next couple of months are going to be really exciting! For those of you who participted in our free, signed book contest, don't worry, you'll still get your signed copy, it will just look a little different that what you expected. ;) I have uploaded the newest version of the book to Zope.org. We have been waiting for the publication deal to happen before we did this, and now that all that is taken care of you will be seeing lots of changes to the book, and hopefully some more useful downloadable formats in the near future. The book can be found on the Zope.org website at http://www.zope.org/Members/michel/ZB/. Once again, thanks for all your comments and support. Without all those eyes out there looking at our work, it would not be what it is today, and hopefully it will only continue to get better thanks to you and the friendly folks at New Riders. -Michel Pelletier

You want to give the object a proxy role, you yourself do not have. Thus, ensure first, that you have this role, then it should work. Dieter

Are you sure the Python was built on FreeBSD? As I know, FreeBSD is able to execute Linux binaries. Dieter

by Thomas M�hlens 20 Feb '01

I stored a whole bunch of parameters in a textfile object (text/plain format) called params. How can I read it into a string variable line by line, that is, read line1 - parse line1 read line2 - parse line2 ... etc Is it memory efficient to do this with some  syntax? cheers, tom __________________________________________________ Do You Yahoo!?

Looking for RDS/ADO server-side XML components
by Brad Clements 20 Feb '01

20 Feb '01

I'd like to use Microsoft's RDS/ADO 2.5 components in an IE 5.5 client, but connect to Zope or some other Python based "server". I think MS has documented just enough of the XML schema for creating an editable recordset in XML.. Was wondering if anyone has worked on this or thought about it. I don't want to do IIS.
