Hi, Thanks for the replies and this has been a big help. Thanks, Larry -------------- Original message from larrymcdonnell(a)att.net: -------------- Hi, It is a simple question, has anyone generated barcodes output within DTML? I am just starting to reseach this and I know there are different formats. I tried googling but I did not find this type of integration. My customer prints out a shipping manifest and work like to add the barcode on this paper output. Thanks in advance, Larry

2nd edition of Zope 3 book available!
by Philipp von Weitershausen 02 Dec '06

02 Dec '06

I'm proud to announce that -- as the first Zope book ever -- my book titled "Web Component Development with Zope 3" has been released as a second edition and is now available from online and local bookstores. Like the first edition, the new book is targeted at all web developers who want to get into Zope 3 or learn more about Zope 3 and Zope 3 technology than they already know. It's accompanied by an extensive example application that's extended throughout the book. *Unlike* the first edition, the second edition is... - up-to-date. The book covers the latest Zope 3 release, Zope 3.3, which has only been released recently. All chapters, all examples, and the appendices have been revised to match the most current Zope 3 codebase. - bigger. Five (!) new chapters, all describing new features in Zope, have been added, many others were extended notably. In total, the book is more than 80 pages thicker than the old one -- at the same price as the old one. - better. With the second edition, the book has been completely revamped. My excellent reviewers from the Zope and Plone community have done a tremendous good job at improving the book's language and technical details. I also improved the didactics in various places. - for you! No matter if you're a Zope 3 developer or just starting to get into Zope 3, I suggest you keep the book under your pillow. Even as a Zope 2 or Plone developer, you'd be surprised how much Zope 3 technology you can now use in Zope 2 -- and this book tells you how! This makes it a must-buy especially for Plone developers as Plone 3.0 is using Zope 3 components for all new development. Find out more at http://worldcookery.com. Philipp -- http://worldcookery.com -- Professional Zope documentation and training 2nd edition of Web Component Development with Zope 3 is now shipping!

RE: [Zope] Zope newbie.... unicode problem

How do I get my hands on the template that has the >embedded Unicode characters? Usually, it is not the template itself. As the template contains text, it should (in principle) be unicode -- but Zope is still not that far. There are patches around to change this state and Zope 2.10 might support unicode templates (but I am unsure). Thus, usually, the template is not unicode and some dynamic parts (included via "tal:content|replace|attributes") are unicode. To analyse those problems (I have set Python's default encoding to my site encoding such that I do no longer see such problems) I would reproduce the problem in an interactive Python interpreter ("bin/zopectl debug" under *nix -- there are also solution for Windows, but you need to search for them yourself) and use "pdb.pm()" to find out all relevant details. -- Dieter

Zope newbie.... unicode problem
by Tyler Nally 30 Nov '06

30 Nov '06

Greetings all, I'm 100% new to Zope. A complete Zope newbie. I've done web Work for more than a dozen years... just never with Zope. When serving a web page, we get an error that involves the fetching and display of a document to the browser. Evidently, it's choking on some unicode bytes when it's expecting plain ascii. I'm assuming it's /usr/lib/zope2.7/lib/python/Products/PageTemplates/PageTemplate.py that's causing the problem as the data isn't somehow massaged correctly before processing arrives at /usr/lib/python2.3/StringIO.py line 203. I don't know if the bad byte is in a zope template, document, or a database record that it's fetching. I do believe this installation of Zope uses Plone... but I've no idea whether Plone is somewhere used in the error stream of all the different calls. Do I need to post more information? Tell me .. and I'll get it. If this comes down to a patch, I've no idea how-to apply a patch once I get my grubby mits upon the patch. So, I'll need a bit of help with that as well. If I've posted this in the wrong place.. please forgive me and point me to the right place that I might ask the proper folk to help me. Thanks a lot .. and thanks in advance Tyler ====================TRACEBACK=============================== 2006-11-29T11:03:37 ERROR(200) SiteError http://www.teamhancock.com/help/bb-install Traceback (most recent call last): File "/usr/lib/zope2.7/lib/python/ZPublisher/Publish.py", line 101, in publish request, bind=1) File "/usr/lib/zope2.7/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/usr/lib/zope2.7/lib/python/ZPublisher/Publish.py", line 39, in call_object result=apply(object,args) # Type s<cr> to step into published object.

when I click on source_groups in acl_users of a plone site I get athe following trace back. when I comment out the offending assert everything seems to work fine. the check the comment to the assert says: # should be one and only one mapping to 'k' i therefore assume, that some of the userrs or groups are defined at more than one place. how is this possible?

Okay, yahooing around I found I have to set the path.
