How to use simplejson to serialize and maintain properties?

Question

For a dictionary containing these two key-value pairs:

str = StringProperty
time = DateTimeProperty

I want to serialize it to JSON, store it in the Datastore, and then fetch it, and deserialize it into the original properties.

Answer 1

Try to do it this way:

d = {
  'str'  : StringProperty,
  'time' : unicode(DateTimeProperty)
}
s = simplejson.dumps(d)
print s
