dantico
Tools to convert Django ORM models to Pydantic models.

Documentation: https://xshapira.github.io/dantico/

The key features are:

Custom Field Support: Create Pydantic Schemas from Django Models with default field type validations out of the box.

Field Validator: Fields can be validated with Pydantic validator or root_validator.

Requirements

Python 3.7+
Django 3.0+
Pydantic 1.6+

Installation
pip install dantico

Usage
Assume we have the following user model definition:
# models.py

from django.db import models

class User(models.Model):

GENDER_MALE = "male"
GENDER_FEMALE = "female"
GENDER_OTHER = "other"

GENDER_CHOICES = (
(GENDER_MALE, "Male"),
(GENDER_FEMALE, "Female"),
(GENDER_OTHER, "Other"),
)

username = models.CharField(max_length=20)
age = models.IntegerField()
gender = models.CharField(
choices=GENDER_CHOICES,
max_length=10,
blank=True,
)
password = models.CharField(max_length=100)
company = models.ForeignKey(
Company,
on_delete=models.CASCADE,
)
languages = models.ManyToManyField(Language)

def __str__(self):
return self.name

Using the ModelSchema class will automatically generate schemas from our User model.
# schemas.py

from dantico import ModelSchema
from users.models import User

class UserSchema(ModelSchema):
class Config:
model = User

json_output = json.dumps(UserSchema.schema(), indent=4)
print(json_output)
