Desert generates serialization schemas for dataclasses and attrs classes. Writing code that’s DRY (“don’t repeat yourself”) helps avoid bugs and improve readability. Desert helps you write code that’s DRY.

Installation

::

pip install desert

or with Poetry_

::

poetry add desert

Usage

.. start-basic-usage

A simple example models two Person objects in a Car.

.. code-block:: python

    from dataclasses import dataclass

    # Or using attrs
    # from attr import dataclass

    from typing import List

import desert

    @dataclass
    class Person:
        name: str
        age: int

    @dataclass
    class Car:
        passengers: List[Person]

    # Load some simple data types.
    data = {'passengers': [{'name': 'Alice', 'age': 21}, {'name': 'Bob', 'age': 22}]}


    # Create a schema for the Car class.
    schema = desert.schema(Car)

    # Load the data.
    car = schema.load(data)
    assert car == Car(passengers=[Person(name='Alice', age=21), Person(name='Bob', age=22)])

.. end-basic-usage
