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
2015-02-14[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
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
2015-01-08Fixed #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.
2015-01-06Fixed #12663 -- Formalized the Model._meta API for retrieving fields.Daniel Pyrathon
Thanks to Russell Keith-Magee for mentoring this Google Summer of Code 2014 project and everyone else who helped with the patch!
2014-12-24Fixed #24041 -- Documented effect of changing a model instance's primary key.Helen Sherwood-Taylor
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.

2014-09-03Fixed #18757, #14462, #21565 -- Reworked database-python type conversionsMarc Tamlyn
Complete rework of translating data values from database Deprecation of SubfieldBase, removal of resolve_columns and convert_values in favour of a more general converter based approach and public API Field.from_db_value(). Now works seamlessly with aggregation, .values() and raw queries. Thanks to akaariai in particular for extensive advice and inspiration, also to shaib, manfre and timograham for their reviews.
