by Stephan Richter 10 Sep '01

10 Sep '01

Hello everyone, it is almost a year now since I released ZQuest 1.0.0 beta 1 (October 2000), but the project is not dead (since I still try to graduate <grin>). In the last two weeks I updated zQuest to the latest, just released, DBObjects version. I also implemented the last missing features and started moving towards a stable version. But enough said. Since it would be too long to list all features in this mail, I would like to point you to these URLs: Zope.org Download: http://www.zope.org/Members/srichter/Products/ZQuest iuveno product page: http://demo.iuveno-net.de/iuveno/Products/ZQuest zQuest Demo: http://photon.cbu.edu:8080/ZQuest/Instances/Demo/index_html (demo/demo) zQuest Features: http://demo.iuveno-net.de/iuveno/Products/ZQuest/Features zQuest Screenshots: http://demo.iuveno-net.de/iuveno/Products/ZQuest/Screenshots zQuest Installation Instructions and Download: http://demo.iuveno-net.de/iuveno/Products/ZQuest/Download In case you get frustrated, since you do not know the API yet or all of this is confusing, then please be patient, the documentation is coming! (If you can't wait, just contact me. ;-) ) I also worked on a release plan. In order to be successful here, I would love to get some beta testers. You can either use the demo installation or download your own. I would need your help between September 10-23. *** Release Plan *** - September 7, 2001 - Feature Freeze.

DBObjects 1.3.0 beta 1 released!
by Stephan Richter 10 Sep '01

10 Sep '01

Hello everyone, okay, it has been a while since I have posted a new release of DBObjects. The reason is not that we did not do anything, but that so much was added and changed that I never had the chance to pack it all up. In Austria DBObjects starts to conquer the Zope development companies. bluedynamics.com is using proiektor (uses DBObjects) to implement sites that are heavily project-oriented. They also developed an Auction Tool that is based on DBObjects that communicates via XML-RPC. uptime, a company based in Vienna, develops the entire Austrian Telekom E-commerce site called Jet2Web using DBObjects, in which also the Auction Tool is being incorporated. The core of the entire shop was written in just 6 weeks, which shows the amount of time that can be saved using the DBObjects! Zope.org Download: http://www.zope.org/Members/srichter/Products/DBObjects iuveno demo site: http://demo.iuveno-net.de/iuveno/Products/DBObjects Please send me any comments, suggestions, criticisms and ideas to srichter(a)cbu.edu. *** New Features *** - Volatile support. You do not need to save any information in the ZODB anymore. Sponsored by bluedynamics.com. - XML-RPC support. Implements some methods that are well-suited for XML-RPC communication. Written by Phillip Auersperg, bluedynamics.com. - QueryFolder support. You can now create virtual DBObjectFolder's which show a certain subset of objects. For example, if you have NewsItems, then you can have a QueryFolder called PublishedNewsItems, that contains only the news items that are marked published. Sponsored by bluedynamics.com. - DBObjects is a product! Finally! You can now use DBObjects as a standalone product and you can now develop your product separately. You simply register your product and DBObjects will know about it. - Move/Copy Support. I finally managed to support the Zope API calls move and copy. - Version/Undo Support. If you like, you can now choose whether you would like to save old versions of you object. All the versions are held in the RDB. You can assign version numbers and mark specific objects as archived, so that they are not removed, when the data is packed (all old versions are being deleted). - Psycop support. DBOjbect can finally talk to PostGreSQL via Psycop as well. Psycop is probably the most advanced Python-PostGreSQL library that also has a nice Zope DA. This allows us finally to use DBObjects is truly serious situations! Thanks to Stefan Holek for his input. - When a FolderishDBObject is initialized, then all the SubObjectFolders are generated automatically now. Sponsored by Stefan Holek, uptime.at. - Zope.py will provide an abstract class that can be used to hang normal ZODB objects into a DBObject tree. Basically, it is a DBObjects API compliant regular Zope Folder. - Added Search Support for DBObjects. You can now search through DBObjects. You simply specify in each DBObject a variable called 'searchableAttributes', which is a tuple containing the names of the attributes that can be searched. The search will look through all the sub-objects as well and then generate a list of **objects** whose search result was positive. - Added a new Support/ directory. It will contain some higher level Support classes, that can be optionally added to a DBObject. Currently, I added the ViewTreeSupport and the UserSupport to it, which were part of the proiektor code base before. - DBObjects should now be everywhere Zope 2.3+ UI compatible. I updated all of the DTML files to the new standards. - Fixed a bug in General.py that was pointed out by Fredrik Svensson. He was testing DBObjects on Windows NT. As far as I know, DBObjects should be Windows NT compatible now. - Changed the ; (semicolon) delimiters to <dtml-var sql_delimiter>, which was also pointed out by Fredrik. *** Planned Features *** - Support for more Databases. Build an abstraction layer, so that differences in DA's can be adjusted. Problem cases are DateTimes and Booleans. - Allow for random primary keys, so that the system does not depend on an id, containertype and containerid anymore. That will be a hard one. - More adaption to the standard Zope API. By now, I have already implemented a good amount of the Zope API, but I think some more work needs to be done. - Use Formulator to automatically generate HTML Forms. After I decreased the time to generate objects, I noticed that I spend most of the time generating new forms. BTW, I am looking for sponsors that would help out financing one or another part of the future development. I'll pay! The amount of time saved using DBObjects is gigantic!

Zope wins Web Tools Readers' Choice Award
by Martijn Pieters 06 Sep '01

06 Sep '01

Zope has won the Readers' Choice award in the Infrastructure category of the Webtechniques Web Tools Awards competition: http://www.webtechniques.com/wtawards/2001/ This in spite (or because of?) the somewhat ill-fitting categories; we shared the category with IBM's DB2 and PostgreSQL, while ColdFusion and Enhydra were listed in the Development category, for example. Still, a great thank you for everyone who voted for us! Amos Lateier is in California right now to receive the award. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

Bug-Fix for PackageProduct patch of PatchKit
by Adrian Hungate 04 Sep '01

04 Sep '01

I have just fixed a potentially troublesome bug in PatchKit that makes products that are packaged on a Windows server incompatible with Unix versions of tar. I was (incorrectly) using os.path.join, which inserts '\' in paths, but on Unix this does not create a file in a subdirectory, just a file with a long, strange name. If you have packaged any products using this, you may need to re-package them. (Sorry - Blame me) The corrected PatchKit is available at http://www.zope.org/Members/haqa/PatchKit .
