A lightweight library for converting complex datatypes into native Python datatypes.
Project description
Homepage: http://marshmallow.rtfd.org/
marshmallow is an ORM/ODM/framework-agnostic library for converting complex datatypes, such as objects, into native Python datatypes. The serialized objects can then be rendered to standard formats such as JSON for use in a REST API.
from datetime import datetime
from marshmallow import Serializer, fields
# A "model"
class Person(object):
def __init__(self, name):
self.name = name
self.date_born = datetime.now()
# A serializer
class PersonSerializer(Serializer):
name = fields.String()
date_born = fields.DateTime()
person = Person("Guido van Rossum")
serialized = PersonSerializer(person)
serialized.data
# {"name": "Guido van Rossum", "date_born": "Sun, 10 Nov 2013 14:24:50 -0000"}Get It Now
$ pip install -U marshmallow

Changelog
0.3.1 (2013-11-16)
Fix bug with serializing dictionaries.
Fix error raised when serializing empty list.
Add only and exclude parameters to Serializer constructor.
Add strict parameter and option: causes Serializer to raise an error if invalid data are passed in, rather than storing errors.
Updated Flask + SQLA example in docs.
0.3.0 (2013-11-14)
Declaring Serializers just got easier. The class Meta paradigm allows you to specify fields more concisely. Can specify fields and exclude options.
Allow date formats to be changed by passing format parameter to DateTime field constructor. Can either be "rfc" (default), "iso", or a date format string.
More useful error message when declaring fields as classes (instead of an instance, which is the correct usage).
Rename MarshallingException -> MarshallingError.
Rename marshmallow.core -> marshmallow.serializer.
0.2.1 (2013-11-12)
Allow prefixing field names.
Fix storing errors on Nested Serializers.
Python 2.6 support.
0.2.0 (2013-11-11)
Field-level validation.
Add fields.Method.
Add fields.Function.
Allow binding of extra data to a serialized object by passing the extra param when initializing a Serializer.
Add relative paramater to fields.Url that allows for relative URLs.
0.1.0 (2013-11-10)
First release.
