2020-07-28[3.1.x] Fixed #31829 -- Used JSONField __contains lookup on key transforms.sage
Backport of 2d8dcba03aae200aaa103ec1e69f0a0038ec2f85 from master
2020-07-28[3.1.x] Fixed #31836 -- Dropped support for JSONField __contains and ↵Mariusz Felisiak
__contained_by lookups on SQLite. The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object". Backport of ba691933cee375195c9c50f333dd4b2a3abbb726 from master.

Oracle. The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object".

2020-05-25[3.1.x] Fixed #31624 -- Avoided subquery usage on QuerySet.all().delete().Simon Charette
Thanks Adam Johnson for the report. Regression in 7acef095d73322f45dcceb99afa1a4e50b520479. Backport of 972000420e08703dd4981466ff67adcd5a61ad4b from master
2020-05-19[3.1.x] Fixed #31607 -- Fixed evaluated Subquery equality.Mariusz Felisiak
Regression in 691def10a0197d83d2d108bd9043b0916d0f09b4. Backport of a125da6a7c79b1d4c55677d0bed6f9b1d7d77353 from master

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 efa1908f662c19038a944129c81462485c4a9fe8. Backport of 3a941230c85b2702a5e1cd97e17251ce21057efa from master
2020-05-14[3.1.x] Fixed #31568 -- Fixed alias reference when aggregating over multiple ↵Simon Charette
subqueries. 691def10a0197d83d2d108bd9043b0916d0f09b4 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. Backport of adfbf653dc1c1d0e0dacc4ed46602d22ba28b004 from master
2020-05-14[3.1.x] Fixed #31566 -- Fixed aliases crash when chaining ↵Simon Charette
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 fb3f034f1c63160c0ff13c609acd01c18be12f80. Thanks Makina Corpus for the report. Backport of 42c08ee46539ef44f8658ebb1cbefb408e0d03fe from master
2020-05-11Refs #30116 -- Simplified regex match group access with Match.__getitem__().Jon Dufresne
The method has been available since Python 3.6. The shorter syntax is also marginally faster.
2020-05-11Optimized Model and QuerySet pickling version comparison.Adam Johnson
2020-05-08Fixed #12990, Refs #27694 -- Added JSONField model field.sage

Special thanks to Mads Jensen, Nick Pope, and Simon Charette for extensive reviews. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2020-05-05Fixed #31538 -- Fixed Meta.ordering validation lookups that are not transforms.Mariusz Felisiak
Regression in 440505cb2cadbe1a5b9fba246bcde6c04f51d07e. Thanks Simon Meers for the report.
2020-04-30Fixed #20581 -- Added support for deferrable unique constraints.Ian Foote
2020-04-27Removed unnecessary tuple wrapping of single format string argument.François Freitag
2020-04-24Refs #31369 -- Deprecated models.NullBooleanField in favor of ↵Tim Schilling
BooleanField(null=True).
2020-04-23Fixed #31500 -- Fixed detecting of unique fields in QuerySet.in_bulk() when ↵Hannes Ljungberg
using Meta.constraints. Detection of unique fields now takes into account non-partial unique constraints.
2020-04-22Avoided unnecessary recompilation of ordering clause regex in SQLCompiler.Adam Johnson
2020-04-20Fixed #31474 -- Made QuerySet.delete() not return the number of deleted ↵Hasan Ramezani
objects if it's zero.
2020-04-15Fixed #31223 -- Added __class_getitem__() to Manager and QuerySet.sobolevn
2020-04-10Fixed #31351 -- Added system checks for partial indexes and unique ↵Ichlasul Affan
constraints support.
2020-04-08Fixed #28184 -- Allowed using a callable for FileField and ImageField storage.miigotu
2020-04-07Refs #27666 -- Ensured relationship consistency on delayed reloads.Simon Charette
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. Co-authored-by: Hasan Ramezani <hasan.r67@gmail.com>
2020-04-06Fixed #31426 -- Added proper field validation to QuerySet.order_by().Simon Charette
Resolve the field reference instead of using fragile regex based string reference validation.
2020-04-06Refs #7098 -- Deprecated passing raw column aliases to order_by().Simon Charette
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.
2020-04-06Fixed #31420 -- Fixed crash when filtering subquery annotation against a ↵Hasan Ramezani
SimpleLazyObject. Thanks Simon Charette for the solution and analysis.
2020-04-04Fixed #31415 -- Fixed crash when nested OuterRef is used with operators or ↵Hasan Ramezani
in database functions.
2020-04-01Refs #12990 -- Moved PostgresSimpleLookup to the ↵Mariusz Felisiak
django.db.models.lookups.PostgresOperatorLookup.
2020-03-31Refs #31403 -- Made SQLInsertCompiler.execute_sql() always return an ↵Adam Johnson
iterable of rows. List of tuples.
2020-03-25Fixed #23916 -- Allowed makemigrations to handle related model name case ↵Adam Johnson
changes. Made autodetector ignore related model name case changes so unnecessary migrations are not created.
2020-03-25Fixed #31396 -- Added binary XOR operator to F expressions.Hannes Ljungberg
2020-03-25Fixed #31377 -- Disabled grouping by aliases on ↵Hasan Ramezani
QuerySet.values()/values_list() when they collide with field names. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Thanks Holovashchenko Vadym for the report.
2020-03-20Refs #29724 -- Added is_dst parameter to QuerySet.datetimes().Hasan Ramezani
Thanks Simon Charette for the review and Mariusz Felisiak for tests.
2020-03-19Fixed #31285 -- Fixed inherited Meta.ordering of "-pk".Jon Dufresne
2020-03-18Refs #31055 -- Made long column names checks support databases aware.Mariusz Felisiak
2020-03-18Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL.Simon Charette
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.
2020-03-05Fixed #29129 -- Skipped UPDATE when adding a model instance with inherited ↵Abhijeet Viswa
primary key that has a default.
2020-03-05Fixed #31327 -- Deprecated providing_args argument for Signal.Jon Dufresne
2020-03-03Fixed #31150 -- Included subqueries that reference related fields in GROUP ↵Mariusz Felisiak
BY clauses. Thanks Johannes Hoppe for the report. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Co-authored-by: Simon Charette <charette.s@gmail.com>
2020-02-28Fixed #31310 -- Fixed hints in checks for using intermediate model with ↵Matheus Cunha Motta
ambiguous foreign key. symmetrical=False is not required since 87b1ad6e7351464c60e751b483d9dfce3a2d3382.
2020-02-27Fixed #31251 -- Disabled grouping by OuterRef() annotation.Rohit
