Hello, It's been a exciting week in Zopeland. The Zope community is cooking up a lot of great stuff! Martijn Fassan and Anthony Pfrunder are working on xml-based content formatting and behavior projects. Ty Sarna is pushing Zope's database capabilities by adding Berkeley DB support. It's hard to keep up with all the great new Zope products and documentation. As always Zope.org is the best place to look for most of the exciting new stuff. * Anthony Pfrunder announced his VisualZope Product which looks quite interesting, though it is very early in development at this point. VisualZope is a collection of ZClasses to provide easy support for javascript/DHTML within the Zope environment. http://www.zope.org/Members/NoneToBe/VisualStudio/new_html http://www.zope.org/pipermail/zope-dev/1999-September/001721.html http://www.zope.org/pipermail/zope-dev/1999-September/001708.html * Martijn Fassan's XMLWidgets is another exciting Zope Project. XMLWidgets allows you to author content in XML and then create behaviors for the XML. http://www.zope.org/Members/faassen/XMLWidgets * Mark Pratt announced that Katrin Kirchner has translated three Zope how-to's into German. http://www.zope.de/bibliothek/How-Tos/ http://www.zope.org/pipermail/zope-announce/1999-October/000042.html * Ty Sarna announced a preliminary version of a Berkeley DB based ZODB storage. This is great news, and marks a great step forward for ZODB. http://www.zope.org/Members/tsarna/BerkeleyStorage * Paul Everitt announced more information about Zope training. http://www.digicool.com/Solutions/Training/ http://www.zope.org/pipermail/zope/1999-October/011453.html * Pam Crosby announced updated Zope documentation, including the still incomplete Zope Developer's Guide and Zope Administrator's Guide. http://www.zope.org/pipermail/zope/1999-October/011462.html * Jeffrey Shell announced the LDAP Roadmap. http://www.zope.org/Members/jshell/LDAP_Roadmap http://www.zope.org/pipermail/zope/1999-October/011571.html * A number of folks are giving talks on Zope throughout the world. Anthony Baxter spoke in Victoria, Australia, and Chris McDonough will be speaking in Philadelphia, USA. http://www.zope.org/pipermail/zope/1999-October/011597.html http://www.zope.org/Members/anthony/talks/luv/ http://www.zope.org/pipermail/zope/1999-September/011333.html http://www.op.net/~darxus/plug/anouncement/anouncement.html * Johan Carlsson announced a Zope Internet Explorer Editor Project. http://www.zope.org/Members/johanc/zie-news1 * Evelyn Mitchell has written an article on Python for IBM's DeveloperWorks. It mentions Zope. http://www-4.ibm.com/software/developer/library/python101.html * Computer Sweden published an article on Zope by Erik Geijer. http://nyheter.idg.se/display.pl?ID=990930-CS5 * Hungarian Chip Magazine published an article on Zope by Arpad Kiss. http://www.zope.org/Members/sekter/zopearticle2 Keep on Zopin' -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com

What about : http://www.zope.org/Members/anthony/talks/luv/index_html Oh - the interdocument 'next' links won't work properly with IE, you will have to scroll manually.

ZClass Permission Mapping Problem
by Albert Kinderman 05 Oct '99

05 Oct '99

Hi: I created a ZClass, memberClass. When I create an instance, I can modify its properties, but I cannot change its id (choosing rename from the contents view of the containing folder). The traceback is below. What permission mapping do I need to support rename? This fails for me as superuser, so I don't believe it is a matter of role permissions. Thanks, Al The example is based on a member with id provost. The object provost does not support this operation Traceback (innermost last): File /usr/local/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope-2.0.1/lib/python/Zope/__init__.py, line 201, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope-2.0.1/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_renameObject) File /usr/local/Zope-2.0.1/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: manage_renameObject) File /usr/local/Zope-2.0.1/lib/python/OFS/CopySupport.py, line 253, in manage_renameObject (Object: ElementWithAttributes) File /usr/local/Zope-2.0.1/lib/python/OFS/CopySupport.py, line 374, in _verifyObjectPaste (Object: ElementWithAttributes) Copy Error: (see above) -- ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Albert Kinderman California State University, Northridge albert.kinderman(a)csun.edu Department of Management Science

RE: [Zope] Using Dreamweaver with zope..
by Theodore Patrick 05 Oct '99

05 Oct '99

Actually, Dreamweaver is much better than you think! At the UCON conference it was released that Dreamweaver is built on a version of ECMASCRIPT(Javascript) and .XML, The entire app(minus some core code) is all javascript and is easily manipulated. The kit you found is a tool for building functionality into Dreamweaver. It is really powerful. As Dreamweaver has FTP access there is no reason that Dreamweaver cannot be a full blown IDE for Zope. There are 3 things that would need to happen: 1. DTML Tags would have to be added to ZOPE under a ZOPE MENU 2. Modify the MIME SETTINGS so Dreamweaver could recognize ZOPE Docs (or rename them in ZOPE) 3. Add ZOPE Logic to the menus. (IF, WHILE, IN) Oracle built a dreamweaver extension to view and edit parameters in an oracle database. With the Dreamweaver SDK there really isn't anything you can't do. Actually there is allot of publically available code already written. EXTENSION CODE http://www.macromedia.com/software/dreamweaver/download/extensions/ EXTENSION KIT http://www.macromedia.com/support/dreamweaver/extend.html Simply look in the Dreamweaver directory.. All the menus and windows are ECMASCRIPT(.js) files. I would definitely be interested, as we use both tools daily. Theodore E.

Hi, I just dug up this documentation on the Macromedia website that could be interesting for anyone using Dreamweaver together with Zope: http://www.macromedia.com/support/dreamweaver/extend/dream2extend.html I also have plans to explore the possibility to integrate Dreamweaver publishing with Zope publishing.

Hi all, How do you test if a file upload field has a value? i.e. Did the user upload a new image or not? If so, do the manage_upload, if not, continue. Something like the following:    Much appreciated, Kevin

RE: [Zope] cgi scripts
by Chris McDonough 05 Oct '99

You don't really use CGI scripts under Zope. Something akin to a CGI script in the Zope world would be an external method, which you must write in Python. A counter script could be implemented as an external method and possibly someone has come up with a clever way to implement one in DTML (the scripting language used by Zope which gets intertwined with HTML display). Good luck!

Re: Change a ZClass's instance's image
by Albert Kinderman 05 Oct '99

05 Oct '99

Kevin Dangoor gave me the solution to a similar problem. However, it takes two steps as currently implemented. 1) A copy of the default (image, document ,etc) is created in the instance. 2) You go to the instance and change the default to the new (image, document, etc) If you can find a way to do it all in one step, please let me know. As you have discovered, if you don't make a copy, the object in the instance is (a pointer back to) the original. If you do not create a copy, any changes you make are to the original. Quoting my response to his email (posted to the list on October 1) [BEGIN QUOTE] Here is a quick write-up for others taken from the example of KM|Net News. In your xProduct, create a DTML document (or method) with id default. This is at the same level as the xClass, xClass_add, xClass_addForm, and xClassFactory. [NOTE: Kevin says to put the default in the xClass. Try it either way.] In your xClass_add, include within the <dtml-with "xClass.createInObjectManager(REQUEST['id'], REQUEST)"> the lines <dtml-call "REQUEST.set('data',default.document_src(REQUEST,RESPONSE))"> <dtml-call "manage_addDTMLDocument('default','',data)"> [changed in the obvious way for a DTML Method] along with any property sheet management call (as explained in the comment in the standard xClass_add). Now when you create an instance of x, the document default will be automatically created within the instance created. Since default is inside of the instance, I believe you must have ZObjectManager as one of the base classes. [I haven't tried it without ZObjectManager as a base class, but I know it works when you do.] [END OF QUOTE] change the words document to image appropriately, and you might have your solution.

Hopefully Andrew Kuchling is reading this... he gave a presentation at the recent DC PIGies meeting about this, and basically said it might be CALLED XML, but it's neither legal nor well-formed. He had a horrendous time parsing it, and when talking with people found out that nobody had tried to parse it with a real XML parser, just regexes... ick, what's the point? I'd talk with him before endeavoring to understand this one.
