"datatime" objects can not be JSON-serialized to be held in sessions

[epandurski@…]

I am using Django 1.6 beta 3.

In my view I try:

now = datetime.datetime.now(pytz.utc)
request.session['lstts'] = now

But I get the following error: ​http://dpaste.com/hold/1375033/

I presume the reason is the new serializer for session objects. I also presume that "datatime" objects must be supported, because they are quite useful and used.

The JSON format doesn't provide a type for dates/datetimes. We'll have to resort to a hack to support this use case.

This was discussed quite a bit during the implementation, and the caveats of JSON serialization have been documented:

​https://docs.djangoproject.com/en/dev/releases/1.6/#default-session-serialization-switched-to-json

​https://docs.djangoproject.com/en/dev/topics/http/sessions/#session-serialization

You can continue to use the PickleSerializer if needed.
