Fixed #9964 -- Ensure that all database operations make transactions dirty, not just write operations. Many thanks to Shai Berger for his work and persistence on this issue. This is BACKWARDS INCOMPATIBLE for anyone relying on the current behavior that allows manually managed read-only transactions to be left dangling without a manual commit or rollback. git-svn-id: http://code.djangoproject.com/svn/django/trunk@15493 bcc190cf-cafb-0310-a4f2-bffc1f526a37 2011-02-12 21:03:34 +08:00			`from django.db import models`

Some style fixes for stuff that was clearly brough tover from doctests. 2013-02-24 05:04:08 +08:00

Fixed #16818 -- Fixed ORM bug with many-to-many add() method where it wasn't committing the change. Thanks, pressureman and kmtracey git-svn-id: http://code.djangoproject.com/svn/django/trunk@17189 bcc190cf-cafb-0310-a4f2-bffc1f526a37 2011-12-10 07:16:56 +08:00

Fixed #16649 -- Refactored save_base logic Model.save() will use UPDATE - if not updated - INSERT instead of SELECT - if found UPDATE else INSERT. This should save a query when updating, but will cost a little when inserting model with PK set. Also fixed #17341 -- made sure .save() commits transactions only after the whole model has been saved. This wasn't the case in model inheritance situations. The save_base implementation was refactored into multiple methods. A typical chain for inherited save is: save_base() _save_parents(self) for each parent: _save_parents(parent) _save_table(parent) _save_table(self) 2012-11-29 18:10:31 +08:00			`class SubMod(Mod):`
