Anssi Kääriäinen 0c7633178f Fixed #24020 -- Refactored SQL compiler to use expressions
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.

Helen Sherwood-Taylor 4ccdf6e57f Fixed #24041 -- Documented effect of changing a model instance's primary key. 2014-12-24 15:06:09 -05:00
Marc Tamlyn 5ca82e710e Fixed #24033 -- Use interval type on Oracle.
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.

Marc Tamlyn 57554442fe Fixed #2443 -- Added DurationField.
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.

Marc Tamlyn e9103402c0 Fixed #18757, #14462, #21565 -- Reworked database-python type conversions
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.
