This is the code I use (if your e-mail doesn't preview code well:
http://paste2.org/p/1921598):
def serialize(self, localtz=None):
"""Converts all the properties of the object into a dict
for use in json
"""
props = {}
def is_valid_key(key):
if not key.startswith('_') and \
not 'password' in key and \
not 'salt' == key:
return True
_items = self.__class__.__dict__
local_at = dict()
if _items.has_key('timezone') and (getattr(self, 'timezone') or
localtz):
timezone = localtz or getattr(self,'timezone')
if _items.has_key('start_time') and getattr(self,'start_time'):
local_at.update(self._localize_time('start_date',
'start_time', timezone.name))
if _items.has_key('end_time') and getattr(self,'end_time'):
local_at.update(self._localize_time('end_date', 'end_time',
timezone.name))
for key, value in _items.items():
if is_valid_key(key):
obj = getattr(self, key)
if hasattr(obj, 'serialize'):
props[key] = obj.serialize()
elif not callable(obj):
if isinstance(obj, datetime) or isinstance(obj, date):
_date = local_at.get(key,None) or obj
props[key] = _date.strftime("%Y-%m-%d")
elif isinstance(obj, time):
_time = local_at.get(key,None) or obj
props[key] = _time.strftime("%I:%M %p")
else:
props[key] = getattr(self, key)
props['id'] = str(self.pk)
return props
