Django MongoDB Backend 6.0.3 has been released!

[Iris (Iris Ho)]

We are pleased to announce that Django MongoDB Backend 6.0.3 is now available!

New features

• Added :ref:`support for matching ObjectIDs in URL patterns `.

• Added polymorphic subfield support to :class:`~django_mongodb_backend.indexes.EmbeddedFieldIndex` and :class:`~django_mongodb_backend.constraints.EmbeddedFieldUniqueConstraint`.

  See :ref:`polymorphic-embedded-model-field-indexes`, :ref:`polymorphic-embedded-model-field-unique-constraints`, :ref:`polymorphic-embedded-model-array-field-indexes`, and :ref:`polymorphic-embedded-model-array-field-unique-constraints`.

• str(queryset.query) now outputs MQL instead of SQL.

Bug fixes

• Made model saving raise an exception to prevent a misconfiguration from resulting in the creation of models with encrypted fields in non-encrypted databases.

• Made makemigrations serialize embedded model references as strings so that references in migrations don’t need to be adjusted if models are later removed.

• Added a helpful NotSupportedError for QuerySet.extra(where=...) and StringAgg(..., distinct=True) rather than crashing with more obscure exceptions.

Deprecated features

• Defining indexes and constraints on embedded models using unique=True, db_index=True, Meta.constraints, Meta.indexes, and Meta.unique_together is deprecated in favor of using :class:`~django_mongodb_backend.indexes.EmbeddedFieldIndex` and :class:`~django_mongodb_backend.constraints.EmbeddedFieldUniqueConstraint` on the top-level model. See :ref:`inline-constraints-and-indexes-deprecation` for an example.

Enjoy the release and if you experience any issues please report them!
