Package to convert arbitrary python objects into DTOs ready for serialization and validation.

Project description

Documentation Status

A fork of awesome R2DTO by @nickswebsite.

Provides easy interface for transformation and validation of arbitrary python objects into DTOs suitable for receiving from and delivering to other services.

Quick Start

Let’s start by creating a simple model class:

class Simpson(object):
    def __init__(self):
        self.first_name = ""
        self.last_name = ""

    def __str__(self):
        return self.first_name + " " + self.last_name

To create a serializer, we need to map attributes to fields of our DTO:

class SimpsonSerializer(Serializer):
    class Meta:
        model = Simpson

    first_name = fields.StringField(name="firstName")
    last_name = fields.StringField(name="lastName")

When you get a payload that requires one of these serializers, call Serializer.load(data).

>>> data = {
...     "firstName": "Homer",
...     "lastName": "Simpson",
... }
>>> s = SimpsonSerializer.load(data)
>>> s
<class '__main__.Simpson'>
>>> str(s)
'Homer Simpson'

To go the other way. Pass the object you want to transfer into the dump method:

>>> homer = Simpson()
>>> homer.first_name = "Homer"
>>> homer.last_name = "Simpson"
>>> s = SimpsonSerializer.dump(homer)
>>> s
{'firstName': 'Homer', 'lastName': 'Simpson'}
