**serpy** is a super simple object serialization framework built for speed.

**serpy** serializes complex datatypes (Django Models, custom classes, ...) to

simple native types (dicts, lists, strings, ...). The native types can easily

be converted to JSON or any other format needed.

The goal of **serpy** is to be able to do this *simply*, *reliably*, and

*quickly*. Since serializers are class based, they can be combined, extended

and customized with very little code duplication. Compared to other popular

Python serialization frameworks like `marshmallow

`_ or `Django Rest Framework Serializers

`_ **serpy** is at

least an `order of magnitude

`_ faster.

Installation

    $ pip install serpy

Examples

========

Simple Example

--------------

.. code-block:: python

    import serpy

    class Foo(object):

        """The object to be serialized."""

        y = 'hello'

        z = 9.5

        def __init__(self, x):

            self.x = x

    class FooSerializer(serpy.Serializer):

        """The serializer schema definition."""

        # Use a Field subclass like IntField if you need more validation.

        x = serpy.IntField()

        y = serpy.Field()

        z = serpy.Field()

    f = Foo(1)

    FooSerializer(f).data

    # {'x': 1, 'y': 'hello', 'z': 9.5}

    fs = [Foo(i) for i in range(100)]

    FooSerializer(fs, many=True).data

    # [{'x': 0, 'y': 'hello', 'z': 9.5}, {'x': 1, 'y': 'hello', 'z': 9.5}, ...]

Nested Example

--------------

.. code-block:: python

    import serpy

    class Nestee(object):

        """An object nested inside another object."""

        n = 'hi'

    class Foo(object):

        x = 1

        nested = Nestee()

    class NesteeSerializer(serpy.Serializer):

        n = serpy.Field()

    class FooSerializer(serpy.Serializer):

        x = serpy.Field()

        # Use another serializer as a field.

        nested = NesteeSerializer()

    f = Foo()

    FooSerializer(f).data

    # {'x': 1, 'nested': {'n': 'hi'}}

Complex Example

---------------

.. code-block:: python

    import serpy

    class Foo(object):

        y = 1

        z = 2

        super_long_thing = 10

        def x(self):

            return 5

    class FooSerializer(serpy.Serializer):

        w = serpy.Field(attr='super_long_thing')

        x = serpy.Field(call=True)

        plus = serpy.MethodField()

        def get_plus(self, obj):

            return obj.y + obj.z

    f = Foo()

    FooSerializer(f).data

    # {'w': 10, 'x': 5, 'plus': 3}

Inheritance Example

-------------------

.. code-block:: python

    import serpy

    class Foo(object):

        a = 1

        b = 2

    class ASerializer(serpy.Serializer):

        a = serpy.Field()

    class ABSerializer(ASerializer):

        """ABSerializer inherits the 'a' field from ASerializer.

        This also works with multiple inheritance and mixins.

        """

        b = serpy.Field()

    f = Foo()

    ASerializer(f).data

    # {'a': 1}

    ABSerializer(f).data

    # {'a': 1, 'b': 2}
