Bake marshmallow schemas based on dataclasses
Project description
marshmallow-recipe
The main goal of this opinionated library is to simplify migration from marshmallow2 to marshmallow3. Also, it helps with:
- Stop writing marshmallow schemas completely: it generates them from dataclass.
- Using different naming cases(camel and capital camel cases are supported).
- Utilizing best practises on fields configuration.
import dataclasses
import datetime
import decimal
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)
Update API example:
import decimal
import dataclasses
import marshmallow_recipe as mr
@dataclasses.dataclass(frozen=True)
@mr.options(none_value_handling=mr.NoneValueHandling.INCLUDE)
class CompanyUpdateData:
name: str = mr.MISSING
annual_turnover: decimal.Decimal | None = mr.MISSING
company_update_data = CompanyUpdateData(name="updated name")
dumped = mr.dump(company_update_data)
assert dumped == {"name": "updated name"} # Note: no "annual_turnover" here
loaded = mr.load(CompanyUpdateData, {"name": "updated name"})
assert loaded.name == "updated name"
assert loaded.annual_turnover is mr.MISSING
loaded = mr.load(CompanyUpdateData, {"annual_turnover": None})
assert loaded.name is mr.MISSING
assert loaded.annual_turnover is None
