| 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. | |||
| 2018-11-17 | Refs #29908 -- Optimized known related objects assignment. | Simon Charette | |
| Since CPython implements a C level attrgetter(*attrs) it even outperforms the most common case of a single known related object since the resulting attribute values tuple is built in C. | |||
| 2018-11-15 | Fixed #17930 -- Allowed ORing (|) with sliced QuerySets. | Ian Foote | |
| 2018-11-14 | Fixed #29835 -- Made RelatedFieldListFilter respect ModelAdmin.ordering. | Hasan Ramezani | |
| 2018-11-13 | Fixed #29641 -- Added support for unique constraints in Meta.constraints. | Simon Charette | |
| This constraint is similar to Meta.unique_together but also allows specifying a name. Co-authored-by: Ian Foote <python@ian.feete.org> | |||
| 2018-11-13 | Refs #29641 -- Refactored database schema constraint creation. | Simon Charette | |
| Added a test for constraint names in the database. Updated SQLite introspection to use sqlparse to allow reading the constraint name for table check and unique constraints. Co-authored-by: Ian Foote <python@ian.feete.org> | |||
| 2018-11-08 | Fixed #29908 -- Fixed setting of foreign key after related set access if ↵ | Simon Charette | |
| ForeignKey uses to_field. Adjusted known related objects handling of target fields which relies on from and to_fields and has the side effect of fixing a bug bug causing N+1 queries when using reverse foreign objects. Thanks Carsten Fuchs for the report. | |||
| 2018-10-29 | Fixed #29547 -- Added support for partial indexes. | Mads Jensen | |
| Thanks to Ian Foote, Mariusz Felisiak, Simon Charettes, and Markus Holtermann for comments and feedback. | |||
| 2018-10-28 | Fixed #29896 -- Fixed incorrect Model.save() cache relation clearing for ↵ | Tim Graham | |
| foreign keys that use to_field. Regression in ee49306176a2d2f1751cb890bd607d42c7c09196. | |||
| 2018-10-24 | Fixed #29869 -- Made UUIDField.to_python() convert integers. | Sanyam Khurana | |
| 2018-10-22 | Fixed #27595 -- Made ForeignKey.get_col() follow target chains. | Simon Charette | |
| Previously, foreign relationships were followed only one level deep which prevents foreign keys to foreign keys from being resolved appropriately. This was causing issues such as improper database value conversion for UUIDField on SQLite because the resolved expression's output field's internal type wasn't correct. Added tests to make sure unlikely foreign reference cycles don't cause recursion errors. Refs #24343. Thanks oyooyo for the report and Wayne Merry for the investigation. | |||
| 2018-10-17 | Moved make_hashable() to django.utils and added tests. | aspalding | |
| 2018-10-17 | Fixed #21171 -- Avoided starting a transaction when a single (or atomic ↵ | Florian Apolloner | |
| queries) are executed. Checked the following locations: * Model.save(): If there are parents involved, take the safe way and use transactions since this should be an all or nothing operation. If the model has no parents: * Signals are executed before and after the previous existing transaction -- they were never been part of the transaction. * if `force_insert` is set then only one query is executed -> atomic by definition and no transaction needed. * same applies to `force_update`. * If a primary key is set and no `force_*` is set Django will try an UPDATE and if that returns zero rows it tries an INSERT. The first case is completly save (single query). In the second case a transaction should not produce different results since the update query is basically a no-op then (might miss something though). * QuerySet.update(): no signals issued, single query -> no transaction needed. * Model/Collector.delete(): This one is fun due to the fact that is does many things at once. Most importantly though: It does send signals as part of the transaction, so for maximum backwards compatibility we need to be conservative. To ensure maximum compatibility the transaction here is removed only if the following holds true: * A single instance is being deleted. * There are no signal handlers attached to that instance. * There are no deletions/updates to cascade. * There are no parents which also need deletion. | |||

| 2018-10-08 | Refs #27795 -- Removed force_text() usage in db/models/sql/query.py. | Jon Dufresne | |
| 2018-10-02 | Fixed #29745 -- Based Expression equality on detailed initialization signature. | Simon Charette | |
| The old implementation considered objects initialized with an equivalent signature different if some arguments were provided positionally instead of as keyword arguments. Refs #11964, #26167. | |||
| 2018-10-02 | Refs #29641 -- Extracted reusable CheckConstraint logic into a base class. | Simon Charette | |
| 2018-10-02 | Refs #11964 -- Changed CheckConstraint() signature to use keyword-only ↵ | Simon Charette | |
| arguments. Also renamed the `constraint` argument to `check` to better represent which part of the constraint the provided `Q` object represents. | |||
