@ -807,10 +807,18 @@ For backwards compatibility, this setting defaulted to using :mod:`pickle`
in Django 1.5.3, but we've changed the default to JSON in 1.6. If you upgrade
and switch from pickle to JSON, sessions created before the upgrade will be
lost. While JSON serialization does not support all Python objects like
:mod:`pickle` does, we highly recommend using JSON-serialized sessions. Also,
as JSON requires string keys, you will likely run into problems if you are
using non-string keys in ``request.session``. See the
:ref:`session_serialization` documentation for more details.
:mod:`pickle` does, we highly recommend using JSON-serialized sessions. Be
aware of the following when checking your code to determine if JSON
serialization will work for your application:
* JSON requires string keys, so you will likely run into problems if you are
using non-string keys in ``request.session``.
* Setting session expiration by passing ``datetime`` values to
:meth:`~django.contrib.sessions.backends.base.SessionBase.set_expiry` will
not work as ``datetime`` values are not serializable in JSON. You can use
integer values instead.
