Hi all, For those watching trunk, revision 9742 added aggregate support to Django. (Yay!)
The short version is that Querysets now have two additional operations - annotate() and aggregate(). For details on how to use these new operations, see the documentation: http://docs.djangoproject.com/en/dev/topics/db/aggregation/ As prior warning - there is one known problem which we are still tracking down. On Windows, using SQLite and Python 2.5, date and decimal values can get corrupted. This doesn't affect other versions of Python (2.4 or 2.6) on Windows, or Python 2.5 on Linux/Mac. I hope to get these problems cleared up very soon. If you are affected, either don't update your SVN checkout, or use a different version of Python (multiple Python versions co-exist fairly easily under Windows). I've opened ticket #10031 to track this known problem. If you find any other issues with aggregates, please open a ticket (or ask on the mailing list/IRC if you're unsure if the problem is usage or bug). Lastly - some thank-yous. This commit wouldn't have been possible without the assistance of many other people. Nicolas Lara did some excellent work turning a specification into a working implementation as part of the 2008 Google Summer of Code. Nicolas - take a bow - you did some excellent work here. Alex Gaynor provided some excellent assistance debugging and fixing a number of problems as we neared completion of the project. Thanks Alex. Justin Bronn used his GIS-fu to get aggregates working with contrib.gis. Thanks Justin. Karen Tracey used her massive personal server farm to provide cross-platform testing. Thanks Karen. Ian Kelly helped out testing and fixing aggregates on Oracle. Thanks Ian. Malcolm Tredinnick did his usual stunning job at reviewing code and picking holes in designs. Thanks Malcolm. Thanks also to the many people that contributed ideas during the design phase, and to those who tested the code as it was developing. Your efforts may not have ended up in the final design or turned into a bug report, but thanks for taking the time to look at an experimental feature. Yours, Russ Magee %-) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
