Fixed #26704 -- Documented DjangoJSONEncoder.

    JSON-serializable object.

    The ``encoder``, which defaults to

    ``django.core.serializers.json.DjangoJSONEncoder``, will be used to

    :class:`django.core.serializers.json.DjangoJSONEncoder`, will be used to

    serialize the data. See :ref:`JSON serialization

    <serialization-formats-json>` for more details about this serializer.

ManyToMany-relations are serialized for the model that defines them and are

represented as a list of PKs.

Date and datetime related types are treated in a special way by the JSON

serializer to make the format compatible with `ECMA-262`_.

Be aware that not all Django output can be passed unmodified to :mod:`json`.

For example, if you have some custom type in an object to be serialized, you'll

have to write a custom :mod:`json` encoder for it. Something like this will

Also note that GeoDjango provides a :doc:`customized GeoJSON serializer

</ref/contrib/gis/serializers>`.

``DjangoJSONEncoder``

~~~~~~~~~~~~~~~~~~~~~

.. class:: django.core.serializers.json.DjangoJSONEncoder

The JSON serializer uses ``DjangoJSONEncoder`` for encoding. A subclass of

:class:`~json.JSONEncoder`, it handles these additional types:

:class:`~datetime.datetime`

   A string of the form ``YYYY-MM-DDTHH:mm:ss.sssZ`` or

   ``YYYY-MM-DDTHH:mm:ss.sss+HH:MM`` as defined in `ECMA-262`_.

:class:`~datetime.date`

   A string of the form ``YYYY-MM-DD`` as defined in `ECMA-262`_.

:class:`~datetime.time`

   A string of the form ``HH:MM:ss.sss`` as defined in `ECMA-262`_.

:class:`~decimal.Decimal`, ``Promise`` (``django.utils.functional.lazy()`` objects), :class:`~uuid.UUID`

   A string representation of the object.

.. versionchanged:: 1.10

    Support for ``Promise`` was added.
