2019-07-23Removed unnecessary code in Model.__init__().Jon Dufresne
As is_related_object is True, the val variable is unused for the remainder of the method. Unnecessary since 53da1e47942f22a56e761d786ba89d05ca55a224.

2019-07-10Fixed #30628 -- Adjusted expression identity to differentiate bound fields.Simon Charette
Expressions referring to different bound fields should not be considered equal. Thanks Julien Enselme for the detailed report. Regression in bc7e288ca9554ac1a0a19941302dea19df1acd21.
2019-07-08Fixed #30397 -- Added app_label/class interpolation for names of indexes and ↵can
constraints.
2019-07-08Refs #29444 -- Added support for fetching a returned non-integer insert ↵Johannes Hoppe
values on Oracle. This is currently not actively used, since the ORM will ask the SQL compiler to only return auto fields.

target field.
2019-06-21Fixed #30421 -- Allowed symmetrical intermediate table for self-referential ↵Nadège Michel

mutating the list of columns in querysets.
2019-06-10Fixed #30548 -- Improved exception when expression contains mixed types.CruxBox
2019-06-05Fixed #30542 -- Fixed crash of numerical aggregations with filter.Étienne Beaulé
Filters in annotations crashed when used with numerical-type aggregations (i.e. Avg, StdDev, and Variance). This was caused as the source expressions no not necessarily have an output_field (such as the filter field), which lead to an AttributeError: 'WhereNode' object has no attribute output_field. Thanks to Chuan-Zheng Lee for the report. Regression in c690afb873cac8035a3cb3be7c597a5ff0e4b261 and two following commits.

Thanks Windson Yang for the initial patch.
2019-05-21Fixed #30494 -- Disabled __year lookup optimization for indirect values.Simon Charette
The previous heuristics were naively enabling the BETWEEN optimization on successful cast of the first rhs SQL params to an integer while it was not appropriate for a lot of database resolved expressions. Thanks Alexey Chernov for the report.
2019-05-18Fixed #30463 -- Fixed crash of deprecation message when Meta.ordering ↵ruchit2801
contains expressions. Regression in 1b1f64ee5a78cc217fead52cbae23114502cf564.
2019-05-16Fixed #30482 -- Prevented unnecessary evaluation of lookup.queryset in ↵Iain Watts

OneToOneField.
2019-05-12Fixed #6785 -- Made QuerySet.get() fetch a limited number of rows.Amir Hadi
Co-authored-by: Tim Graham <timograham@gmail.com> Co-authored-by: Patryk Zawadzki <patrys@room-303.com> Co-Authored-By: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2019-05-07Fixed #30349 -- Fixed QuerySet.exclude() on FilteredRelation.Rob
Using annotated FilteredRelations raised a FieldError when coupled with exclude(). This is due to not passing filtered relation fields to the subquery created in split_exclude(). We fixed this issue by passing the filtered relation data to the newly created subquery. Secondly, in the case where an INNER JOIN is used in the excluded subquery, the ORM would trim the filtered relation INNER JOIN in attempt to simplify the query. This will also remove the ON clause filters generated by the FilteredRelation. We added logic to not trim the INNER JOIN if it is from FilteredRelation.
2019-05-07Fixed #26678 -- Doc'd that RelatedManager.add()/remove()/set() accepts the ↵Tobias Kunze
field the relation points to.
2019-05-06Fixed #30339 -- Made Model.delete(keep_parents=True) preserves nested parent ↵Stephen Brown
reverse relationships. Thanks Simon Charette for the review.

2019-05-02Fixed #29529 -- Allowed models.fields.FilePathField to accept a callable path.Mykola Kokalko
2019-05-01Fixed #30409 -- Allowed using foreign key's attnames in ↵zeyneloz
unique/index_together and Index's fields.

condition on Oracle and SQLite.

custom validator is callable.
2019-04-18Fixed #30367 -- Changed "pip install" to "python -m pip install" in docs, ↵Ramiro Morales
comments and hints.

2019-04-18Fixed #30335, #29139 -- Fixed crash when ordering or aggregating over a ↵can
nested JSONField key transform.
2019-04-17Fixed #30191 -- Selected only referenced fields during cascade deletion.Simon Charette
The non-referenced fields can only be deferred if no deletion signals receivers are connected for their respective model as connected as these receivers might expect all fields of the deleted model to be present. Thanks Ed Morley for the report.
2019-04-17Refs #18676 -- Enabled fast-delete for m2m_changed senders.Simon Charette
There's no reason to disable fast-delete when an intermediary many-to-many model has connected m2m_changed receivers because the signal is only sent when related manager's clear() and remove() methods are directly called. This must have been overlooked in 1cd6e04cd4f768bcd4385b75de433d497d938f82 given no regression tests fail when m2m_changed is not taken into consideration to determine if fast-delete can be enabled.
2019-04-16Fixed #30368 -- Fixed prefetch_related() for GenericForeignKey when PK is ↵Vinny Do
also a FK.
2019-04-15Refs #23758 -- Used RecursionError instead of RuntimeError to raise nested ↵Simon Charette
subquery errors. RecursionError was introduced in Python 3.5 and subclasses RuntimeError.
2019-04-15Refs #27149 -- Based recursive nested subquery detection on ↵Simon Charette
sys.getrecursionlimit(). This makes sure the test_avoid_infinite_loop_on_too_many_subqueries test doesn't fail on systems with a non-default recursion limit.
2019-04-15Fixed #30325 -- Reverted "Fixed #29725 -- Removed unnecessary join in ↵Mariusz Felisiak
QuerySet.count() and exists() on a many-to-many relation." This reverts commit 1299421cadc4fcf63585f2f88337078e43e660e0 due to a regression with custom managers.
2019-04-14Fixed #30343 -- Fixed prefetch_related() for GenericForeignKey when PK of ↵Mariusz Felisiak
related field is UUIDField.
2019-04-08Fixed #30330 -- Fixed setting of primary key to None during fast-delete.Florian Apolloner
