2011-10-07Fixed #17003 - prefetch_related should support foreign keys/one-to-oneLuke Plant
Support for `GenericForeignKey` is also included. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16939 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-10-06Removed ForeignRelatedObjectsDescriptor.RelatedManager.delete_manager, which ↵Luke Plant
has been unused since [14507] And cleaned up the result, allowing more consistency with the other related descriptors. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16931 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-10-05Fixed #16937 - added `QuerySet.prefetch_related` to prefetch many related ↵Luke Plant
objects. Many thanks to akaariai for lots of review and feedback, bug finding, additional unit tests and performance testing. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16930 bcc190cf-cafb-0310-a4f2-bffc1f526a37

Thanks to ivan_virabyan for the great patch! (For the record, some very small tweaks were made by me). git-svn-id: http://code.djangoproject.com/svn/django/trunk@16929 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-09-30Fixed #14270 - related manager classes should be cachedLuke Plant
Thanks to Alex Gaynor for the report and initial patch, and mrmachine for more work on it. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16916 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-09-29Cleanups to related manager code, especially in use of closures.Luke Plant
The related manager classes are defined within functions, and the methods had inconsistent and confusing usage of closures vs. parameters on self to retrieve needed information. Everything is stored on self now. Also some methods were not using super() where they should have been. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16913 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-09-11Fixed #14138 -- Removed a superfluous import in the sqlite3 DB backend.Ramiro Morales
This could be of help with some issues people were seeing when deploying Django with sqlite and Apache. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16799 bcc190cf-cafb-0310-a4f2-bffc1f526a37

Justin Bronn for his Oracle wizardry. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16793 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-09-10Fixed #16809 -- Forced MySQL to behave like a database. This avoids a ↵Russell Keith-Magee
problem where queries that do IS NONE checks can return the wrong result the first time they are executed if there is a recently inserted row. Thanks to James Pyrich for the debug work and patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16785 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-09-09Fixed #7596. Added Model.objects.bulk_create, and make use of it in several ↵Alex Gaynor
places. This provides a performance benefit when inserting multiple objects. THanks to Russ for the review, and Simon Meers for the MySQl implementation. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16739 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-08-25Make ManyToManyField model references more robust.Malcolm Tredinnick
In r16679 a test was added to verify something had been fixed when a unicode string type was passed in as a model name. The name has to be ASCII convertible, but in Python 2.6 and earlier, it must also have str type. This commit fixes the problem for earlier Python versions and is almost identical to a patch from b.leskes in #6045. Fixes #16689. Refs #6045. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16682 bcc190cf-cafb-0310-a4f2-bffc1f526a37

Thanks to GDorn for the patch. Fixed #15494. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16668 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-23Fixed #16299 -- Ensure that unicode strings can be used to identify classes ↵Russell Keith-Magee
in ForeignKey and ManyToManyFields. Unicode strings aren't actually legal as class names, but this is an issue if you use from __future__ import unicode_literals in your models.py file. Thanks to Martijn Bastiaan for the report, and Anthony Briggs for the final patch. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16663 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-08-23Fixed an isnull=False filtering edge-case. Fixes #15316.Malcolm Tredinnick
The bulk of this patch is due to some fine analysis from Aleksandra Sendecka. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16656 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-23Added convenience method for viewing Query SQL without params.Malcolm Tredinnick
This is the old Query.as_sql() method revived: it's like Query.__str__, but the parameters aren't substituted into the placeholders. Thus, it's a more accurate representation of the SQL the (default) backend will see. Entirely internal. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16655 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-22Fixed #14876 -- Ensure that join promotion works correctly when there are ↵Russell Keith-Magee
nullable related fields. Thanks to simonpercivall for the report, oinopion and Aleksandra Sendecka for the original patch, and to Malcolm for helping me wrestle the edge cases to the ground. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16648 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-08-22Improved error message display during validation errors.Malcolm Tredinnick
When reporting a validation error (during model validation or fixture loading, for example), the error messages now report the bad value as well as the expected type. This can make identifying the offending field and problem a bit easier. Fixed #11595. Patch from raulcd and wildfire with supervision from Russell. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16638 bcc190cf-cafb-0310-a4f2-bffc1f526a37

database backends (such as MySQL/InnoDB) that do not support deferred constraint checking.

DB backend compatible with psycopg2 2.4.2. Implemented this by adding an internal hook for work that should be performed before that point. Also, regarding the `DatabaseCreation.set_autocommit()` method: * Stop using it for such tasks * Stop providing an implementation that tries to cover all the possible idioms a third party database backend DB-API 2 driver could need to activate autocommit. It is now left for third party backends to implement. This can be backwards incompatible in the case of user applications that: * Had started using this method * Use a third a party database backend git-svn-id: http://code.djangoproject.com/svn/django/trunk@16520 bcc190cf-cafb-0310-a4f2-bffc1f526a37

2011-06-19Removed more code for handling of PostgreSQL versions older than 8.2; use ↵Ramiro Morales
always "INSERT... RETURNING..." rather than "INSERT...; SELECT CURRVAL...". Thanks Christoph Pettus for the report and hints. Fixes #12180. Refs [16423]. git-svn-id: http://code.djangoproject.com/svn/django/trunk@16443 bcc190cf-cafb-0310-a4f2-bffc1f526a37
2011-06-19Fixed #11065, #11285 -- Streamlined PostgreSQL version detection, fixing ↵Ramiro Morales
incompatibility with multi-db. Thanks findepi for the report. Changed our internal representation of the PostgreSQL version from tuples to integers as used by libpq and psycopg2. This simplifies version comparison operations. Also, using the associated libpq/psycopg2 API allows to remove the need for manually issuing in-band ``SELECT version()`` SQL queries to obtain the server version (or at least reduce its number if version of psycopg2 in use is older than 2.0.12).
