2026-03-12Fixed #36727 -- Deprecated Field.get_placeholder in favor of ↵Simon Charette
get_placeholder_sql. The lack of ability of the get_placeholder call chain to return SQL and parameters separated so they can be mogrified by the backend at execution time forced implementations to dangerously interpolate potentially user controlled values. The get_placeholder_sql name was chosen due to its proximity to the previous method, but other options such as Field.as_sql were considered but ultimately rejected due to its different input signature compared to Expression.as_sql that might have lead to confusion. There is a lot of overlap between what Field.get_db_prep_value and get_placeholder_sql do but folding the latter in the former would require changing its return signature to return expression which is a way more invasive change than what is proposed here. Given we always call get_db_prep_value it might still be an avenue worth exploring in the future to offer a publicly documented interface to allow field to take an active part in the compilation chain. Thanks Jacob for the review.

This was missed when Field.check(databases) was introduced.
2025-10-29Refs #35381 -- Delegated ArrayField element prepping to ↵Clifford Gama
base_field.get_db_prep_save. Previously, ArrayField always used base_field.get_db_prep_value when saving, which could differ from how base_field prepares data for save. This change overrides ArrayField.get_db_prep_save to delegate to the base_field's get_db_prep_save, ensuring elements like None in JSONField arrays are saved correctly as SQL NULL instead of JSON null.
2025-10-13Replaced multi-level relative imports with absolute imports in django/.lyova24
2025-06-18Fixed #32770 -- Added system check to ensure django.contrib.postgres is ↵Clifford Gama
installed when using its features. Added postgres.E005 to validate 'django.contrib.postgres' is in INSTALLED_APPS when using: * PostgreSQL-specific fields (ArrayField, HStoreField, range fields, SearchVectorField), * PostgreSQL indexes (PostgresIndex and all subclasses), and * ExclusionConstraint The check provides immediate feedback during system checks rather than failing later with obscure runtime and database errors. Thanks to Simon Charette and Sarah Boyce for reviews.

Follow up to 7deeabc7c7526786df6894429ce89a9c4b614086. These lookups aren't vulnerable to SQL injection because both accept only integer indexes. It is a part of good practices.
