Introduction

Pydantic is a great Python library to perform data serialization and validation.

Django REST framework is a framework built on top of Django which allows writing REST APIs.

If like me you develop DRF APIs and you like pydantic , drf-pydantic is for you 😍.

Installation

pip install drf-pydantic

Usage

General

Use drf_pydantic.BaseModel instead of pydantic.BaseModel when creating your models:

from drf_pydantic import BaseModel

class MyModel(BaseModel):
  name: str
  addresses: list[str]

Whenever you need a DRF serializer you can get it from the model like this:

MyModel.drf_serializer

ℹ️ INFO
Models created using drf_pydantic are fully idenditcal to those created by pydantic and only the drf_serializer attribute is added on class creation.

Custom Base Models

You can also use it as a mixin with your existing pydantic models (no need to change your existing code 🥳):

from drf_pydantic import BaseModel as DRFBaseModel
from pydantic import BaseModel

class MyBaseModel(BaseModel):
  value: int

class MyModel(DRFBaseModel, MyBaseModel):
  name: str
  addresses: list[str]

⚠️ ATTENTION
Inheritance order is important: drf_pydantic.BaseModel must always go before the pydantic.BaseModel class.

Roadmap

• Add ENUM support
• Add option to create custom serializer for complex models
