restler-serialization 0.4.1

Restler provides flexible and configurable JSON and XML object serialization for the web

Restler is an object Serialization library for the web. It supports translating objects to JSON or XML. Currently, it is targeted at Google App Engine with python 2.7.

Installation

Install Restler from PyPi using easy_install or pip; or download the package and run:

python setup.py install

(Running setup.py requires setuptools.)

For use on Google App Engine, you will need to install the code in the restler directory somewhere in your path.

Running Tests

To run restler’s tests:

pip install -r requirements.txt -t lib
python -m unittest discover

Running tests requires python 2.7 the Google App Engine SDK or Google Cloud SDK

Usage

A db.Model or ndb.Model instance can be serialized with the default settings using to_json or to_xml.

>>> jean = Person(first_name="Jeanne", last_name="d'Arc", ssn="N/A")
>>> to_json(jean)
'{"first_name": "Jeanne", "last_name": "d\'Arc", "ssn": "N/A"}'

To include only certain fields, use a ModelStrategy. When using a ModelStrategy, you will need to use a restler model decorator.

>>> @ae_db_serializer
>>> class User(db.Model)
>>>    ...

Now setup the ModelStrategy

>>> person_strategy = ModelStrategy(Person).include("first_name", "last_name")
>>> to_json(jean, person_strategy)
'{"first_name": "Jeanne", "last_name": "d'Arc"}'

Or, to exclude specified fields:

>>> person_strategy = ModelStrategy(Person, include_all_fields=True).exclude("ssn")
>>> to_json(jean, person_strategy)
'{"first_name": "Jeanne", "last_name": "d'Arc"}'

For more details on customizing serialization, see the documentation.
