2013-08-30Fixed #20988 -- Added model meta option select_on_saveAnssi Kääriäinen
The option can be used to force pre 1.6 style SELECT on save behaviour. This is needed in case the database returns zero updated rows even if there is a matching row in the DB. One such case is PostgreSQL update trigger that returns NULL. Reviewed by Tim Graham. Refs #16649

2013-08-22Fixed model.__eq__ and __hash__ for no pk value casesAnssi Kääriäinen
The __eq__ method now considers two instances without primary key value equal only when they have same id(). The __hash__ method raises TypeError for no primary key case. Fixed #18864, fixed #18250 Thanks to Tim Graham for docs review.
2013-08-22Fixed #20955 -- select_related regressionAnssi Kääriäinen
In cases where the same connection (from model A to model B along the same field) was needed multiple times in a select_related query, the join setup code mistakenly reused an existing join.

2013-08-21Fixed #20946 -- model inheritance + m2m failureAnssi Kääriäinen
Cleaned up the internal implementation of m2m fields by removing related.py _get_fk_val(). The _get_fk_val() was doing the wrong thing if asked for the foreign key value on foreign key to parent model's primary key when child model had different primary key field.
2013-08-21Fixed #20820 -- Model inheritance + m2m fixture loading regressionAnssi Kääriäinen
Tests by Tim Graham, report from jeroen.pulles@redslider.net.
2013-08-21Fixed #14056 -- Made sure LEFT JOIN aren't trimmed in ORDER BYAnssi Kääriäinen
If LEFT JOINs are required for correct results, then trimming the join can lead to incorrect results. Consider case: TBL A: ID | TBL B: ID A_ID 1 1 1 2 Now A.order_by('b__a') did use a join to B, and B's a_id column. This was seen to contain the same value as A's id, and so the join was trimmed. But this wasn't correct as the join is LEFT JOIN, and for row A.id = 2 the B.a_id column is NULL.

2013-08-07Fixed #17424 -- annotate() + exclude() bugAnssi Kääriäinen
The bug was already fixed by 01b9c3d5193fe61b82ae8b26242a13fdec22f211, so only tests added. At the same time promote_joins()'s uncoditional flag is gone, it isn't needed for anything any more.

2013-07-31Fixed #20348 -- Consistently handle Promise objects in model fields.Tai Lee
All Promise objects were passed to force_text() deep in ORM query code. Not only does this make it difficult or impossible for developers to prevent or alter this behaviour, but it is also wrong for non-text fields. This commit changes `Field.get_prep_value()` from a no-op to one that resolved Promise objects. All subclasses now call super() method first to ensure that they have a real value to work with.

2013-07-26Fixed related model lookup regressionAnssi Kääriäinen
It has been possible to use models of wrong type in related field lookups. For example pigs__in=[a_duck] has worked. Changes to ForeignObject broke that. It might be a good idea to restrict the model types usable in lookups. This should be done intentionally, not accidentally and without any consideration for deprecation path.
2013-07-26Fixed #20625 -- Chainable Manager/QuerySet methods.Loic Bistuer
Additionally this patch solves the orthogonal problem that specialized `QuerySet` like `ValuesQuerySet` didn't inherit from the current `QuerySet` type. This wasn't an issue until now because we didn't officially support custom `QuerySet` but it became necessary with the introduction of this new feature. Thanks aaugustin, akaariai, carljm, charettes, mjtamlyn, shaib and timgraham for the reviews.

In the combination of .values().aggregate() the aggregate_select_mask didn't include the aggregates added. This resulted in bogus query. Thanks to Trac alias debanshuk for report.
