Package to convert arbitrary python objects into DTOs ready for serialization and validation.
Project description
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'}
