Simon Charette dc27f3ee0c Fixed #19259 -- Added group by selected primary keys support. 2015-03-29 22:03:30 -04:00
Anssi Kääriäinen fb146193c4 Fixed #24171 -- Fixed failure with complex aggregate query and expressions
The query used a construct of qs.annotate().values().aggregate() where
the first annotate used an F-object reference and the values() and
aggregate() calls referenced that F-object.

Also made sure the inner query's select clause is as simple as possible,
and made sure .values().distinct().aggreate() works correctly.

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.

Anssi Kääriäinen bd337184f1 Fixed #23877 -- aggregation's subquery missed target col
Aggregation over subquery produced syntactically incorrect queries in
some cases as Django didn't ensure that source expressions of the
aggregation were present in the subquery.

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.

Anssi Kääriäinen ecaba36028 Improved Query join promotion logic
There were multiple cases where join promotion was a bit too aggressive.
This resulted in using outer joins where not necessary.

Refs #21150.

Anssi Kääriäinen ed0d720b78 Fixed #21150 -- select_related + annotate join promotion failure
Added tests for a .annotate().select_related() join promotion failure.
This happened to work on master but was currently untested.

Anssi Kääriäinen 83554b018e Fixed #21126 -- QuerySet value conversion failure

columns for compiler.resolve_columns() method.

Anssi Kääriäinen 33dd8f5442 Fixed random aggregation_regress test_more_more_more() failure
The cause was assuming that an unordered queryset returns the values
always in the same order.

Anssi Kääriäinen d3f00bd570 Refactored qs.add_q() and utils/tree.py
The sql/query.py add_q method did a lot of where/having tree hacking to
get complex queries to work correctly. The logic was refactored so that
it should be simpler to understand. The new logic should also produce
leaner WHERE conditions.

The changes cascade somewhat, as some other parts of Django (like
add_filter() and WhereNode) expect boolean trees in certain format or
they fail to work. So to fix the add_q() one must fix utils/tree.py,
some things in add_filter(), WhereNode and so on.

This commit also fixed add_filter to see negate clauses up the path.
A query like .exclude(Q(reversefk__in=a_list)) didn't work similarly to
.filter(~Q(reversefk__in=a_list)). The reason for this is that only
the immediate parent negate clauses were seen by add_filter, and thus a
tree like AND: (NOT AND: (AND: condition)) will not be handled
correctly, as there is one intermediary AND node in the tree. The
example tree is generated by .exclude(~Q(reversefk__in=a_list)).

Still, aggregation lost connectors in OR cases, and F() objects and
aggregates in same filter clause caused GROUP BY problems on some
databases.

Fixed #17600, fixed #13198, fixed #17025, fixed #17000, fixed #11293.
