2019-09-10Fixed #30754 -- Prevented inclusion of aliases in partial index conditions.Simon Charette
SQLite doesn't repoint table aliases in partial index conditions on table rename which breaks the documented table alteration procedure. Thanks Pēteris Caune for the report.
2019-09-09Fixed #28107 -- Added ↵Vojtech Bocek
DatabaseFeatures.allows_group_by_selected_pks_on_model() to allow enabling optimization for unmanaged models.
2019-09-09Refs #29444 -- Allowed returning multiple fields from INSERT statements on ↵Johannes Hoppe
PostgreSQL. Thanks Florian Apolloner, Tim Graham, Simon Charette, Nick Pope, and Mariusz Felisiak for reviews.
2019-09-09Refs #29444 -- Fixed DateField constructor in ↵Johannes Hoppe
db.backends.oracle.utils.InsertVar.
2019-09-09Fixed #30757 -- Added a system check to ensure max_length fits the longest ↵Nick Pope
choice.
2019-09-06Fixed DatabaseFeatures.can_introspect_check_constraints on MariaDB < ↵Mariusz Felisiak
10.2.22, 10.3.0 - 10.3.9. Regression in e2c6a0858d7d9ad85eda353076a5b46608b704a9.
2019-09-05Fixed #30750 -- Added support for check constraints on MySQL 8.0.16+.Mariusz Felisiak
2019-09-04Fixed #27910 -- Added enumeration helpers for use in Field.choices.Shai Berger
These classes can serve as a base class for user enums, supporting translatable human-readable names, or names automatically inferred from the enum member name. Additional properties make it easy to access the list of names, values and display labels. Thanks to the following for ideas and reviews: Carlton Gibson, Fran Hrženjak, Ian Foote, Mariusz Felisiak, Shai Berger.

2019-09-03Fixed #30691 -- Made migrations autodetector find dependencies for foreign ↵Viktor Lomakin
keys altering.
2019-09-03Refs #29444 -- Made db.backends.oracle.utils.InsertVar use str as default.Johannes Hoppe
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.
2019-09-02Refs #28442 -- Adjusted related lookups handling of expression rhs.Simon Charette
Expressions should never be prepared as other Lookup.get_prep_lookup implementations hint at by returning early on the presence of the resolve_expression attribute. The previous solution was only handling lookups against related fields pointing at AutoFields and would break for foreign keys to other fields. It was also causing bidirectional coupling between model fields and expressions which the method level import of OuterRef was a symptom of.
2019-08-29Refs #25367 -- Simplified OrderBy and Lookup by using Case() instead of ↵Mariusz Felisiak
RawSQL() on Oracle. Follow up to efa1908f662c19038a944129c81462485c4a9fe8.
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>
2019-08-27Fixed #30727 -- Made Subquery pickle without evaluating their QuerySet.Andrew Brown
Subquery expression objects, when pickled, were evaluating the QuerySet objects saved in its _constructor_args attribute.
2019-08-26Refs #30591 -- Fixed introspection of check and unique column constraints on ↵Mariusz Felisiak
MariaDB. Unnamed unique and check columns constraints have the same name as a column. Ensure uniqueness by using custom names. Thanks Adnan Umer for the report.
2019-08-23Replaced subprocess commands by run() wherever possible.Claude Paroz
2019-08-22Fixed #30712 -- Allowed BLOB/TEXT defaults on MySQL 8.0.13+.Nasir Hussain
2019-08-21Fixed #21039 -- Added AddIndexConcurrently/RemoveIndexConcurrently ↵Mads Jensen
operations for PostgreSQL. Thanks to Simon Charettes for review. Co-Authored-By: Daniel Tao <daniel.tao@gmail.com>
2019-08-20Fixed #29979, Refs #17337 -- Extracted AutoField field logic into a mixin ↵Nick Pope
and refactored AutoFields. This reduces duplication by allowing AutoField, BigAutoField and SmallAutoField to inherit from IntegerField, BigIntegerField and SmallIntegerField respectively. Doing so also allows for enabling the max_length warning check and minimum/maximum value validation for auto fields, as well as providing a mixin that can be used for other possible future auto field types such as a theoretical UUIDAutoField.
2019-08-19Fixed #29260 -- Skipped an UPDATE when adding a model instance with primary ↵Hasan Ramezani
key that has a default.
2019-08-18Refs #28428 -- Made FileField.upload_to support pathlib.Path.Claude Paroz
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 #27676 -- Allowed BLOB/TEXT defaults on MariaDB 10.2.1+.Adam Johnson
2019-08-16Fixed #30687 -- Fixed using of OuterRef() expressions in distance lookups.Andrew Brown
2019-08-15Fixed #30449 -- Fixed RelatedFieldListFilter/RelatedOnlyFieldListFilter to ↵zeyneloz
respect model's Meta.ordering. Regression in 6d4e5feb79f7eabe8a0c7c4b87f25b1a7f87ca0b. Co-Authored-By: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2019-08-14Optimized Field.deconstruct() by using elif.Mads Jensen
2019-08-13Refs #25367 -- Moved Oracle Exists() handling to contextual methods.Simon Charette
Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in the following cases. 1. When part of a SELECT clause. 2. When part of a ORDER BY clause. 3. When compared against another expression in the WHERE clause. This commit moves the systematic CASE WHEN wrapping of Exists.as_oracle to contextual .select_format, Lookup.as_oracle, and OrderBy.as_oracle methods in order to avoid unnecessary wrapping.
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.
2019-08-12Refs #24793 -- Removed bogus connection argument from SQLCompiler.compile() ↵Simon Charette
calls. The method doesn't expect a connection object to be passed as its second argument.
2019-08-12Refs #11964 -- Made constraint support check respect required_db_features.Simon Charette
This will notably silence the warnings issued when running the test suite on MySQL.
2019-08-12Refs #23879 -- Made introspection respect required_db_features.Simon Charette
2019-08-05Fixed #28393 -- Added helpful error messages for invalid ↵Diederik van der Boor

source expressions is not filterable.
2019-08-02Fixed #30661 -- Added models.SmallAutoField.Nick Pope
2019-08-02Removed obsolete mentions of a check constraint in ↵Mariusz Felisiak
BaseDatabaseSchemaEditor.add_constraint()/remove_constraint() docstrings.

2019-07-30Refs #30593 -- Added _parse_constraint_columns() hook to introspection on ↵Hasan Ramezani
MariaDB.
2019-07-27Refs #28147 -- Fixed setting of OneToOne and Foreign Key fields to None when ↵Jon Dufresne
using attnames. Regression in 519016e5f25d7c0a040015724f9920581551cab0.
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.
2019-07-25Fixed #27995 -- Added error messages on unsupported operations following ↵Hasan Ramezani
union(), intersection(), and difference().
2019-07-25Fixed #30657 -- Allowed customizing Field's descriptors with a ↵Jon Dufresne
descriptor_class attribute. Allows model fields to override the descriptor class used on the model instance attribute.
2019-07-25Refs #30657 -- Made DeferredAttribute.__init__() to take a field instance ↵Jon Dufresne
instead of a field name.
2019-07-23Improved error message when index in __getitem__() is invalid.Jon Dufresne
2019-07-23Refs #29548 -- Fixed DatabaseWrapper.display_name on MariaDB.Mariusz Felisiak
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.
