2015-09-19[1.8.x] Fixed #25160 (again) -- Moved data loss check on reverse relations.Aymeric Augustin
Moved data loss check when assigning to a reverse one-to-one relation on an unsaved instance to Model.save(). This is exactly the same change as e4b813c but for reverse relations. Backport of c3904de from master

Model.save() This mostly reverts 5643a3b51be338196d0b292d5626ad43648448d3 and 81e1a35c364e5353d2bf99368ad30a4184fbb653. Thanks Carl Meyer for review. Backport of 5980b05c1fad69eef907e0076aa2dc837edab529 from master

2015-02-23[1.8.x] Fixed #24381 -- removed ForeignObjectRel opts and to_optsAnssi Kääriäinen
These cached properies were causing problems with pickling, and in addition they were confusingly defined: field.rel.model._meta was not the same as field.rel.opts. Instead users should use field.rel.related_model._meta inplace of field.rel.opts, and field.rel.to._meta in place of field.rel.to_opts. Backport of f95122e541df5bebb9b5ebb6226b0013e5edc893 from master

2015-02-20[1.8.x] Update converters to take a consistent set of parameters.Marc Tamlyn
As suggested by Anssi. This has the slightly strange side effect of passing the expression to Expression.convert_value has the expression passed back to it, but it allows more complex patterns of expressions. Backport of 32d4db66b9 from master
2015-02-20[1.8.x] Fixed #24343 -- Ensure db converters are used for foreign keys.Marc Tamlyn
Joint effort between myself, Josh, Anssi and Shai. Conflicts: django/db/models/query.py tests/model_fields/models.py Backport of 4755f8fc25331c739a6f932cc8aba0cc9e62e352 from master.
2015-02-14[1.8.x] Fixed #24289 -- Reversed usage of Field.many_to_one and one_to_many.Loic Bistuer
Thanks Carl Meyer and Tim Graham for the reviews and to all involved in the discussion. Backport of 18c0aaa9123579375294fcc4a8ee7e3530176b88 from master

Backport of 0f54cf28c09a80254571487e3af93be2096cfdac from master
2015-02-03[1.8.x] Fixed #23617 -- Added get_pk_value_on_save()Anssi Kääriäinen
The method is mainly intended for use with UUIDField. For UUIDField we want to call the field's default even when primary key value is explicitly set to None to match the behavior of AutoField. Thanks to Marc Tamlyn and Tim Graham for review. Backport of 8adc59038cdc6ce4f9170e4de2d716d940e136b3 from master
2015-01-29[1.8.x] Fixed #23940 -- Allowed model fields to be named `exact`.Simon Charette
An explicit `__exact` lookup in the related managers filters was interpreted as a reference to a foreign `exact` field. Thanks to Trac alias zhiyajun11 for the report, Josh for the investigation, Loïc for the test name and Tim for the review. Backport of eb4cdfbdd64a95b303eaaa40a070521aa58362fd from master

2015-01-16Fixed #24092 -- Widened base field support for ArrayField.Marc Tamlyn
Several issues resolved here, following from a report that a base_field of GenericIpAddressField was failing. We were using get_prep_value instead of get_db_prep_value in ArrayField which was bypassing any extra modifications to the value being made in the base field's get_db_prep_value. Changing this broke datetime support, so the postgres backend has gained the relevant operation methods to send dates/times/datetimes directly to the db backend instead of casting them to strings. Similarly, a new database feature has been added allowing the uuid to be passed directly to the backend, as we do with timedeltas. On the other side, psycopg2 expects an Inet() instance for IP address fields, so we add a value_to_db_ipaddress method to wrap the strings on postgres. We also have to manually add a database adapter to psycopg2, as we do not wish to use the built in adapter which would turn everything into Inet() instances. Thanks to smclenithan for the report.
2015-01-12Fixed #9893 -- Allowed using a field's max_length in the Storage.Pavel Shpilev
2015-01-10Move % addition to lookups, refactor postgres lookups.Marc Tamlyn
These refactorings making overriding some text based lookup names on other fields (specifically `contains`) much cleaner. It also removes a bunch of duplication in the contrib.postgres lookups.
2015-01-08Fixed #24020 -- Refactored SQL compiler to use expressionsAnssi Kääriäinen
Refactored compiler SELECT, GROUP BY and ORDER BY generation. While there, also refactored select_related() implementation (get_cached_row() and get_klass_info() are now gone!). Made get_db_converters() method work on expressions instead of internal_type. This allows the backend converters to target specific expressions if need be. Added query.context, this can be used to set per-query state. Also changed the signature of database converters. They now accept context as an argument.

2014-12-23Refs #2443 -- Move the durationfield converter logic.Marc Tamlyn
This reduces how frequently this logic is run significantly. Thanks to Anssi for the suggestion.
2014-12-23Fixed #24033 -- Use interval type on Oracle.Marc Tamlyn
Use INTERVAL DAY(9) TO SECOND(6) for Durationfield on Oracle rather than storing as a NUMBER(19) of microseconds. There are issues with cx_Oracle which require some extra data manipulation in the database backend when constructing queries, but it handles the conversion back to timedelta objects cleanly. Thanks to Shai for the review.
2014-12-20Fixed #2443 -- Added DurationField.Marc Tamlyn
A field for storing periods of time - modeled in Python by timedelta. It is stored in the native interval data type on PostgreSQL and as a bigint of microseconds on other backends. Also includes significant changes to the internals of time related maths in expressions, including the removal of DateModifierNode. Thanks to Tim and Josh in particular for reviews.
