Changelog

master (unreleased)

1.2.0 (2019-10-21)

• Added a mixin that allows custom filters for queryable properties (both class- and decorator-based) to be implemented using multiple functions/methods for different lookups

• Added some ready-to-use queryable property implementations (ValueCheckProperty, RangeCheckProperty) to simplify common code patterns

• Added a standalone version of six to the package requirements

1.1.0 (2019-06-23)

• Queryable property filters (both annotation-based and custom) can now be used across relations when filtering querysets (i.e. a queryset can now be filtered by a queryable property on a related model)

• Queryset annotations can now refer to annotatable queryable properties defined on a related model

• Querysets can now be ordered by annotatable queryable properties defined on a related model

• Filters and annotations that reference annotatable queryable properties will not select the queryable property annotation anymore in Django versions below 1.8 (ordering by such a property will still lead to a selection in these versions)

• Fixed unnecessary selections of queryable property annotations in querysets that don’t return model instances (i.e. queries with .values() or .values_list())

• Fixed unnecessary fields in GROUP BY clauses in querysets that don’t return model instances (i.e. queries with .values() or .values_list()) in Django versions below 1.8

• Fixed an infinite recursion when constructing the HAVING clause for annotation-based filters that are not an aggregate in Django 1.8

1.0.2 (2019-06-02)

• The lookup parameter of custom filter implementations of queryable properties will now receive the combined lookup string if multiple lookups/transforms are used at once instead of just the first lookup/transform

• Fixed the construction of GROUP BY clauses when annotating queryable properties based on aggregates

• Fixed the construction of HAVING clauses when annotating queryable properties based on aggregates in Django versions below 1.9

• Fixed the ability to pickle queries and querysets with queryable properties functionality in Django versions below 1.6

1.0.1 (2019-05-11)

• Added support for Django 2.2

1.0.0 (2018-12-31)

• Initial release
