2020-05-21Fixed #30375 -- Added FOR NO KEY UPDATE support to ↵Manuel Weitzman
QuerySet.select_for_update() on PostgreSQL.
2020-05-14Fixed #31568 -- Fixed alias reference when aggregating over multiple subqueries.Simon Charette
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.
2020-05-14Fixed #31566 -- Fixed aliases crash when chaining values()/values_list() ↵Simon Charette
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.
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.
2020-03-25Fixed #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.
2020-01-15Refs #31136 -- Made QuerySet.values()/values_list() group only by selected ↵Mariusz Felisiak
annotation. Regression in 0f843fdd5b9b2f2307148465cd60f4e1b2befbb4.
2020-01-04Fixed #31136 -- Disabled grouping by aliases on QuerySet.values()/values_list().Mariusz Felisiak
Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Thanks Sigurd Ljødal for the report.
2019-12-23Fixed #31109 -- Disabled grouping by aliases on QuerySet.exists().Simon Charette
Clearing the SELECT clause in Query.has_results was orphaning GROUP BY references to it. Thanks Thierry Bastian for the report and Baptiste Mispelon for the bisect. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80.
2019-12-19Fixed #31094 -- Included columns referenced by subqueries in GROUP BY on ↵Simon Charette
aggregations. Thanks Johannes Hoppe for the report. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
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.
2019-11-21Refs #25367 -- Made Query.build_filter() raise TypeError on non-conditional ↵Simon Charette
expressions.
2019-11-21Fixed #30484 -- Added conditional expressions support to CheckConstraint.Simon Charette
2019-11-21Refs #25367 -- Moved conditional expression wrapping to the Exact lookup.Simon Charette
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
values to tuples. Regression in 8a281aa7fe76a9da2284f943964a9413697cff1f.
2019-09-24Fixed #30796 -- Prevented select_related() from mutating a queryset on chaining.Simon Charette
Thanks Darren Maki for the report.
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>
2019-08-16Fixed #30687 -- Fixed using of OuterRef() expressions in distance lookups.Andrew Brown
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.
2019-06-28Fixed #28408 -- Added error message when updating with annotated expressions ↵can
on joined fields. Co-Authored-By: Simon Charette <charette.s@gmail.com>
2019-06-19Fixed #29834 -- Fixed column mismatch crash with ↵can
QuerySet.values()/values_list() and order_by() on combined querysets.
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.
2019-04-30Fixed #30412 -- Fixed crash when adding check constraints with OR'ed ↵can
condition on Oracle and SQLite.
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.
2019-03-23Refs #30188 -- Avoided GROUP BY when aggregating over non-aggregates.Simon Charette
2019-03-23Refs #30188 -- Prevented double annotation of subquery when aggregated over.Simon Charette
Thanks Can Sarıgöl for the suggested trimming approach.

2019-03-23Fixed #21703 -- Fixed a crash when excluding a related field with a F().Simon Charette
2019-03-21Removed obsolete Lookup hook to prepare rhs expressions.Simon Charette
After 3a505c70e7b228bf1212c067a8f38271ca86ce09, all _prepare() methods return self.
2019-03-21Refs #27149, #29542 -- Simplified subquery parentheses wrapping logic.Simon Charette
2019-03-21Refs #27149 -- Moved subquery expression resolving to Query.Simon Charette
This makes Subquery a thin wrapper over Query and makes sure it respects the Expression source expression API by accepting the same number of expressions as it returns. Refs #30188. It also makes OuterRef usable in Query without Subquery wrapping. This should allow Query's internals to more easily perform subquery push downs during split_exclude(). Refs #21703.
2019-03-21Refs #30158 -- Added alias argument to Expression.get_group_by_cols().Simon Charette
2019-02-13Fixed #30184 -- Removed ellipsis characters from shell output strings.Dan Davis
Partially reverted 50b8493581fea3d7137dd8db33bac7008868d23a (refs #29654) to avoid a crash when the user shell doesn't support non-ASCII characters.
2019-02-06Fixed #30159 -- Removed unneeded use of OrderedDict.Nick Pope
Dicts preserve order since Python 3.6.
2019-01-16Fixed #30044 -- Raised a FieldError on inherited field update attempts.Simon Charette
2018-11-21Fixed #29949 -- Refactored db introspection identifier converters.Mariusz Felisiak
Removed DatabaseIntrospection.table_name_converter()/column_name_converter() and use instead DatabaseIntrospection.identifier_converter(). Removed DatabaseFeatures.uppercases_column_names. Thanks Tim Graham for the initial patch and review and Simon Charette for the review.
