* fix OpenAPIRenderer for timedelta * added test for rendering openapi with timedelta * fix OpenAPIRenderer for timedelta * added test for rendering openapi with timedelta * Removed usage of field.choices that triggered full table load (#8950) Removed the `{{ field.choices|yesno:",disabled" }}` block because this triggers the loading of full database table worth of objects just to determine whether the multi-select widget should be set as disabled or not. Since this "disabled" marking feature is not present in the normal select field, then I propose to remove it also from the multi-select. * Added Deprecation Warnings for CoreAPI (#7519) * Added Deprecation Warnings for CoreAPI * Bumped removal to DRF315 * Update rest_framework/__init__.py * Update rest_framework/filters.py * Update rest_framework/filters.py * Update tests/schemas/test_coreapi.py * Update rest_framework/filters.py * Update rest_framework/filters.py * Update tests/schemas/test_coreapi.py * Update tests/schemas/test_coreapi.py * Update setup.cfg * Update rest_framework/pagination.py --------- Co-authored-by: Asif Saif Uddin <auvipy@gmail.com> * Update copy right timeline * Fix NamespaceVersioning ignoring DEFAULT_VERSION on non-None namespaces (#7278) * Fix the case where if the namespace is not None and there's no match, NamespaceVersioning always raises NotFound even if DEFAULT_VERSION is set or None is in ALLOWED_VERSIONS * Add test cases * fix OpenAPIRenderer for timedelta * added test for rendering openapi with timedelta * added testcase for rendering yaml with minvalidator for duration field (timedelta) --------- Co-authored-by: Rizwan Shaikh <rshaikh@ces-ltd.com> Co-authored-by: Lenno Nagel <lenno@namespace.ee> Co-authored-by: David Smith <39445562+smithdc1@users.noreply.github.com> Co-authored-by: Asif Saif Uddin <auvipy@gmail.com> Co-authored-by: Konstantin Kuchkov <konstantin.kuchkov@gmail.com>
