I dunno how this affects me and not everyone else who uses this tool. It
looks like the default JSON serializer for web2py has a huge flaw. But if
that were true, it would have been noticed by lots 'o people before. So it
must be impure thinking on my part.
My objects are being serialized with long ints. The long ints are rendered
as Python long ints with an "L" at the end, such as "110L". This is
illegal in Javascript and results in a fatal error.
I examined the code behind the gluon.serializers and found the default
serializer used:
def custom_json(o):
if hasattr(o, 'custom_json') and callable(o.custom_json):
return o.custom_json()
if isinstance(o, (datetime.date,
datetime.datetime,
datetime.time)):
return o.isoformat()[:19].replace('T', ' ')
elif isinstance(o, (int, long)):
return int(o)
elif isinstance(o, decimal.Decimal):
return str(o)
elif isinstance(o, lazyT):
return str(o)
elif isinstance(o, XmlComponent):
return str(o)
elif isinstance(o, set):
return list(o)
elif hasattr(o, 'as_list') and callable(o.as_list):
return o.as_list()
elif hasattr(o, 'as_dict') and callable(o.as_dict):
return o.as_dict()
else:
raise TypeError(repr(o) + " is not JSON serializable")
Yep. There it is. Give it a long instance of 110 and it returns 110L
every time. Javascript responds with "SyntaxError: No identifiers allowed
directly after numeric literal" every time.
Where am I going wrong?
