marshmallow-recipe 0.0.9

Bake marshmallow schemas based on dataclasses

marshmallow-recipe

The main goal of this opinionated library is to simplify migration from marshmallow2 to marshmallow3. Also, it helps with:

1. Stop writing marshmallow schema completely: it generates them from dataclass.
2. Using different naming cases(camel and capital camel cases are supported).
3. Utilizing best practises on fields configuration.

import dataclasses
import marshmallow_recipe as mr
import uuid

@dataclasses.dataclass(frozen=True)
class Transaction:
    id: uuid.UUID
    created_at: datetime.datetime
    processed_at: datetime.datetime | None
    amount: decimal.Decimal

transaction = Transaction(
    id=uuid.uuid4(),
    created_at=datetime.datetime.utcnow(),
    processed_at=None,
    amount=decimal.Decimal(42),
 )

# dumps the transaction to a dict
raw = mr.dump(transaction) 

# loads a transaction from the dict
mr.load(Transaction, raw)

# provides a generated marshmallow schema for dataclass
mr.schema(Transaction)
