2019-12-10Used Signature API instead of deprecated inspect.getcallargs().Baptiste Mispelon
inspect.getcallargs() was deprecated in Python 3.5 and the Signature API (PEP 362) has better support for decorated functions (by default, it follows the __wrapped__ attribute set by functools.wraps for example).
2019-12-06Made Query.check_filterable() use bool by default instead of str.Alex Aktsipetrov
2019-12-06Fixed #31060 -- Reallowed window expressions to be used in conditions ↵Alex Aktsipetrov
outside of queryset filters. Regression in 4edad1ddf6203326e0be4bdb105beecb0fe454c4. Thanks utapyngo for the report.
2019-12-02Fixed #30953 -- Made select_for_update() lock queryset's model when using ↵Mariusz Felisiak
"self" with multi-table inheritance. Thanks Abhijeet Viswa for the report and initial patch.

2019-11-21Refs #11964 -- Removed SimpleCol in favor of Query(alias_cols).Simon Charette
This prevent having to pass simple_col through multiple function calls by defining whether or not references should be resolved with aliases at the Query level.

2019-11-13Fixed #30971 -- Prevented Query.resolve_lookup_value() from coercing list ↵George Marshall

2019-10-29Fixed #30899 -- Lazily compiled import time regular expressions.Hasan Ramezani
2019-10-24Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend.Simon Charette
This required moving the entirety of DELETE SQL generation to the compiler where it should have been in the first place and implementing a specialized compiler on MySQL/MariaDB. The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax for queries spanning over multiple tables.

PostgreSQL. Thanks Florian Apolloner, Tim Graham, Simon Charette, Nick Pope, and Mariusz Felisiak for reviews.
2019-09-02Fixed #30739 -- Fixed exclusion of multi-valued lookup against outer rhs.Simon Charette
OuterRef right hand sides have to be nested, just like F rhs have to, during the subquery pushdown split_exclude performs to ensure they are resolved against the outer query aliases.
2019-08-29Fixed #25367 -- Allowed boolean expressions in QuerySet.filter() and exclude().Matthew Schinckel
This allows using expressions that have an output_field that is a BooleanField to be used directly in a queryset filters, or in the When() clauses of a Case() expression. Thanks Josh Smeaton, Tim Graham, Simon Charette, Mariusz Felisiak, and Adam Johnson for reviews. Co-Authored-By: NyanKiyoshi <hello@vanille.bid>
2019-08-17Fixed #29545 -- Fixed using filter lookups againts nested subquery expressions.Simon Charette
Made sql.Where resolve lhs of its child nodes. This is necessary to allow filter lookups against nested subquery expressions to properly resolve their OuterRefs to Cols. Thanks Oskar Persson for the simplified test case.
2019-08-16Fixed #30687 -- Fixed using of OuterRef() expressions in distance lookups.Andrew Brown
2019-08-13Refs #25367 -- Moved select_format hook to BaseExpression.Simon Charette
This will expose an intermediary hook for expressions that need special formatting when used in a SELECT clause.
2019-08-02Fixed #30668 -- Made QuerySet.filter() raise NotSupportedError if any of ↵aaktsipetrov
source expressions is not filterable.
2019-07-25Added Query.is_sliced property.Mariusz Felisiak
Previously, we used Query.can_filter() mainly to check if a query is sliced what was confusing.
2019-07-11Refs #30557 -- Fixed crash of ordering by ptr fields when Meta.ordering ↵Mariusz Felisiak
contains F() expressions. Thanks Can Sarıgöl for the report. Follow up to 8c5f9906c56ac72fc4f13218dd90bdf9bc8a248b.
2019-07-11Fixed #30557 -- Fixed crash of ordering by ptr fields when Meta.ordering ↵Hasan Ramezani
contains expressions.
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.
2019-06-28Fixed #28408 -- Added error message when updating with annotated expressions ↵can
on joined fields. Co-Authored-By: Simon Charette <charette.s@gmail.com>

QuerySet.order_by and Meta.ordering.
2019-05-18Fixed #30463 -- Fixed crash of deprecation message when Meta.ordering ↵ruchit2801
contains expressions. Regression in 1b1f64ee5a78cc217fead52cbae23114502cf564.
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.
2019-05-03Fixed #29692 -- Fixed removing ordering parts for multiline RawSQL expressions.can
2019-04-30Fixed #30412 -- Fixed crash when adding check constraints with OR'ed ↵can
condition on Oracle and SQLite.
2019-04-23Fixed #29810 -- Fixed crash of select_related() on FilteredRelation with ↵can
empty result.
2019-04-18Fixed #30335, #29139 -- Fixed crash when ordering or aggregating over a ↵can
nested JSONField key transform.
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.
2019-03-23Fixed #30246 -- Reused annotation aliases references in aggregation filters.Simon Charette
Thanks Jan Baryła for the detailed report and the reduced test case.
