[storm] How to JSON encode a item from a ResultSet

[Mario Zito]

Jamu:

Yes, testing also indicates that Date attrs were not serialized.
I will test other datatypes while I work on the appl code.
So this is the corrected code.

*def encode_storm_object(object):*
*     if not hasattr(object, "__storm_table__"):*
*         raise TypeError(repr(object) + " is not JSON serializable")*
*
*
*     result = {}*
*     cls_info = get_cls_info(object.__class__)*
*     for name in cls_info.attributes.iterkeys():*
*         value= getattr(object, name)*
*         if ("<type 'datetime.date'>" == str(value.__class__)): *
*             value= str(value)*
*         result[name] = value*
*     return result*

*json_str = json.dumps(storm_obj, default=encode_storm_object)*

Sorry, but the only way that worked was using the string "*<type
'datetime.date'>*" to test the object class.
I tried using *isinstance(obj, "datetime.date")* but did not work.
Maybe you have a better solution here to check the attr class ... I am new
in Python :-(
