marshmallow is an ORM/ODM/framework-agnostic library for converting complex datatypes, such as objects, to and from native Python datatypes. The serialized objects can then be rendered to standard formats such as JSON for use in an HTTP API.
from datetime import datetime
from marshmallow import Schema, fields, pprint
# A "model"
class Person(object):
def __init__(self, name):
self.name = name
self.date_born = datetime.now()
# A serializer schema
class PersonSchema(Schema):
name = fields.String()
date_born = fields.DateTime()
person = Person("Guido van Rossum")
schema = PersonSchema()
result = schema.dump(person)
pprint(result.data)
# {"name": "Guido van Rossum", "date_born": "2014-08-17T14:42:12.479650+00:00"}$ pip install -U marshmallow
Full documentation is available at http://marshmallow.rtfd.org/ .
- Python >= 2.6 or >= 3.3
marshmallow has no external dependencies outside of the Python standard library, although python-dateutil is recommended for robust datetime deserialization.
