Marc, I definitely agree with your approach. I was working on a similar solution when I saw your post. I just released an alpha version of a library for handling more complex object serialization, jsonpickle (http://code.google.com/p/jsonpickle/).

Thank you for this post. It is definitely helping me today. Here are some code corrections and printing that may assist others.

#!/usr/bin/python
import sys, traceback, pdb

import simplejson

class Person:
def __init__(self, name=None):
if not name:
self.name = self.namepeople = [ Person('Marc'), Person('Rachel') ]
else:
self.name = name

pdb.set_trace()

people = Person()
# Fails with error that Field class “is not JSON serializable”
#s = simplejson.dumps(fields)

# This is what we want.
print “————————————-”
print “dumps”
print “————————————-”
s = simplejson.dumps([p.__dict__ for p in people.namepeople])
print s

# Deserialize
print “————————————-”
print “load clones”
print “————————————-”
clones = simplejson.loads(s)
print clones

# Now give our clones some life
for clone in clones:
p = Person()
p.__dict__ = clone
print “————————————-”
print “instantiate clones”
print “————————————-”
print p
print p.name
