Installing toastedmarshmallow-enum

pip install toastedmarshmallow-enum

Using Toasted Marshmallow Enum

Using Toasted Marshmallow Enum in an existing Marshmallow Schema is as easy as defining the enum class attribute as an EnumField. For example:

from enum import Enum

import toastedmarshmallow
from marshmallow import fields, Schema

from toastedmarshmallow_enum import EnumField

class Level(Enum):
    LOW = '0'
    MEDIUM = '1'
    HIGH = '2'

class UserSchema(Schema):
    class Meta:
        jit = toastedmarshmallow.Jit

    name = fields.String()
    level = EnumField(Level)

How it works

Dump methods:

class User:
    def __init(name, level):
        self.name = name
        self.level = level

schema = DummyUserSchema()

user = User(name='John Doe', level=Level.HIGH)
print(schema.dump(user).data)
# {'name': 'John Doe', 'level': 2}

print(schema.load({'name': 'John Doe', 'level: 2}).data)
# {'name': 'John Doe', 'level': 'HIGH'}
