Fixed #31584 -- Fixed crash when chaining values()/values_list() after Exists() annotation and aggregation on Oracle. 
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in
the GROUP BY clause.

Regression in efa1908f66.

Simon Charette adfbf653dc Fixed #31568 -- Fixed alias reference when aggregating over multiple subqueries. 
691def10a0 made all Subquery() instances
equal to each other which broke aggregation subquery pushdown which
relied on object equality to determine which alias it should select.

Subquery.__eq__() will be fixed in an another commit but
Query.rewrite_cols() should haved used object identity from the start.

Refs #30727, #30188.

Thanks Makina Corpus for the report.

Simon Charette 42c08ee465 Fixed #31566 -- Fixed aliases crash when chaining values()/values_list() after annotate() with aggregations and subqueries. 
Subquery annotation references must be resolved if they are excluded
from the GROUP BY clause by a following .values() call.

Regression in fb3f034f1c.

Thanks Makina Corpus for the report.

Fixed #31580 -- Added error messages on distinct() following union(), intersection(), and difference(). 2020-05-13 14:44:10 +02:00
Jon Dufresne d6aff369ad Refs #30116 -- Simplified regex match group access with Match.__getitem__(). 
The method has been available since Python 3.6. The shorter syntax is
also marginally faster.

Hannes Ljungberg 447980e72a Fixed #31500 -- Fixed detecting of unique fields in QuerySet.in_bulk() when using Meta.constraints. 
Detection of unique fields now takes into account non-partial unique
constraints.

Adam Johnson 67f9d076cf
Avoided unnecessary recompilation of ordering clause regex in SQLCompiler. 2020-04-22 20:28:01 +02:00
Hasan Ramezani 35a67b3731 Fixed #31474 -- Made QuerySet.delete() not return the number of deleted objects if it's zero. 2020-04-20 09:51:54 +02:00

miigotu 210657b791 Fixed #28184 -- Allowed using a callable for FileField and ImageField storage. 2020-04-08 11:26:17 +02:00
Simon Charette 1d16c5d562 Refs #27666 -- Ensured relationship consistency on delayed reloads. 
Delayed reloads of state models broke identity based relationships
between direct and non-direct ancestors.

Basing models.Options related objects map of model labels instead of
their identity ensured relationship consistency is maintained.

Refs #30966.

Simon Charette 513948735b Fixed #31426 -- Added proper field validation to QuerySet.order_by(). 
Resolve the field reference instead of using fragile regex based string
reference validation.
 2020-04-06 10:19:49 +02:00
Simon Charette 98ea4f0f46 Refs #7098 -- Deprecated passing raw column aliases to order_by(). 
Now that order_by() has expression support passing RawSQL() can achieve
the same result.

This was also already supported through QuerySet.extra(order_by) for
years but this API is more or less deprecated at this point.

migrations are not created.

Mariusz Felisiak 5c8441a0b8 Refs #31055 -- Made long column names checks support databases aware. 2020-03-18 18:41:40 +01:00
Simon Charette 9f07f27124 Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL. 
Both backends order NULLs first on ascending ordering and last on
descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when
asc(nulls_first) and desc(nulls_last) are used since it prevents indice
usage.
