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.

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.

This required implementing a limited form of dynamic dispatch to combine expressions with numerical output. Refs #26355 should eventually provide a better interface for that.

Thanks Tim Graham for completing the initial patch.
2016-04-03Fixed #26101 -- Allowed introspection of base_field.model in RangeFieldanna
Used the same test and fix as in #25867. This required initializing base_field in RangeField.__init__, not when setting the attribute.
2016-02-16Fixed #26215 -- Fixed RangeField/ArrayField serialization with None valuesClaude Paroz
Also added tests for HStoreField and JSONField. Thanks Aleksey Bukin for the report and Tim Graham for the initial patch and the review.
2015-09-21Fixed #24629 -- Unified Transform and Expression APIsJosh Smeaton
2015-07-14Fixed #24716 -- Deprecated Field._get_val_from_obj()Thomas Stephenson
The method duplicates the functionality of Field.value_from_object() and has the additional downside of being a privately named public API method.
2015-06-06Instead of using DjangoJSONEncoder, use base_field's value_to_string.Matthew Somerville
Note this means the serialization of e.g. IntegerRangeField now has strings for lower and upper, so use to_python when they came back in (same behaviour as ArrayField, hopefully, from where I also got the set_attributes_from_name function).
2015-06-05Fixed #24937 -- fix serialization of Date(Time)RangeField.Matthew Somerville
Use the DjangoJSONEncoder so that datetime and date are encoded appropriately.
2015-06-04Fixed #24837 -- field__contained_by=RangeMarc Tamlyn
Provide `contained_by` lookups for the equivalent single valued fields related to the range field types. This acts as the opposite direction to rangefield__contains. With thanks to schinckel for the idea and initial tests.

2015-01-10Fixed #24001 -- Added range fields for PostgreSQL.Marc Tamlyn
Added support for PostgreSQL range types to contrib.postgres. - 5 new model fields - 4 new form fields - New validators - Uses psycopg2's range type implementation in python
