[Zope-Annce] DBObjects 1.3.0 beta 1 released!
Mon, 10 Sep 2001 02:19:06 -0500
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!

*** 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
- 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
- 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!
