Serializing list to JSON

Question

I am sending information between client and Django server, and I would like to use JSON to this. I am sending simple information - list of strings. I tried using djang

Yes, but then what do you do about the django objects? simple json tends to choke on them.

If the objects are individual model objects (not querysets, e.g.), I have occasionally stored the model object type and the pk, like so:

seralized_dict = simplejson.dumps(my_dict, 
                     default=lambda a: "[%s,%s]" % (str(type(a)), a.pk)
                     )

to de-serialize, you can reconstruct the object referenced with model.objects.get(). This doesn't help if you are interested in the object details at the type the dict is stored, but it's effective if all you need to know is which object was involved.
