Mariusz Felisiak 34b52f8572
Renamed the allow_sliced_subqueries database feature to allow_sliced_subqueries_with_in.

false only on MySQL which doesn't support sliced subqueries only with

Aymeric Augustin ed83881e64 Fixed #23820 -- Supported per-database time zone.
The primary use case is to interact with a third-party database (not
primarily managed by Django) that doesn't support time zones and where
datetimes are stored in local time when USE_TZ is True.

Configuring a PostgreSQL database with the TIME_ZONE option while USE_TZ
is False used to result in silent data corruption. Now this is an error.

parameters are passed through the connection.ops.value_to_db_* methods,
depending on their type.

Aymeric Augustin fe6b5e62b1 Normalized the implementation of get_db_converters.
Put the types in the same order and checked for None consistently.

Andriy Sokolovskiy 29b4a3f513 Removed duplicate attribute in MySQL DatabaseSchemaEditor. 2015-03-30 19:23:41 -04:00
Anssi Kääriäinen 8f30556329 Renamed Field.rel attribute to remote_field
Field.rel is now deprecated. Rel objects have now also remote_field
attribute. This means that self == self.remote_field.remote_field.

In addition, made the Rel objects a bit more like Field objects. Still,
marked ManyToManyFields as null=True.

Marc Tamlyn 32d4db66b9 Update converters to take a consistent set of parameters.
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.

Claude Paroz 68a439a18d Removed supports_binary_field flag as all backends support them
It was mainly for MySQL on Python 3, but now the current
recommended MySQL driver for Python 3 (mysqlclient) does support
binary fields, it is unneeded. Refs #20377.
2015-01-11 23:34:47 +01:00
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.

Tim Graham 93d73dac91 Moved DatabaseCreation.data_types properties to DatabaseWrapper.

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.

The .dates() queries were implemented by using custom Query, QuerySet,

database converters APIs.
