craiglabenz / django_model_serializer.py

Created May 17, 2013 13:16

Django provides nice model serializers, but if their structure isn't exactly what you want then use this template to serialize them yourself.

	def serialize(self):
	obj = {}
	for field in self._meta.fields:
	value = field.value_from_object(self)
	if isinstance(value, datetime.datetime):
	obj[field.name] = field.value_to_string(self)
	else:
	obj[field.name] = value
	return obj

The following code (which `webook_api.py` executes) produces an empty list, whereas copying the same values in here (http://www.freeformatter.com/xpath-tester.html#ad-output) produces the expected output
