This addons provides a new type used to declare Pydantic model as Extendable class.

from pydantic import BaseModel
from extendable_pydantic import ExtendableModelMeta
from extendable import context, registry

class Location(BaseModel, metaclass=ExtendableModelMeta):
    lat = 0.1
    lng = 10.1

class ExtendedLocation(Location, extends=Location):
    name: str

_registry = registry.ExtendableClassesRegistry()
context.extendable_registry.set(_registry)
_registry.init_registry()

loc = Location(**{"lat": 12.3, "lng": 13.2, "name": "My Loc"})

loc.dict() == {"lat": 12.3, "lng": 13.2, "name": "My Loc"}
#> True

loc.schema()
#> {'title': 'Location', 'type': 'object', 'properties': {'lat': {'title': 'Lat', 'default': 0.1, 'type': 'number'}, 'lng': {'title': 'Lng', 'default': 10.1, 'type': 'number'}, 'name': {'title': 'Name', 'type': 'string'}}, 'required': ['name']}
