RELEASE.md

Release type: minor

Remove deprecated strawberry.scalar(cls, ...) wrapper pattern and ScalarWrapper, deprecated since 0.288.0.

You can run strawberry upgrade replace-scalar-wrappers <path> to automatically replace built-in scalar wrapper imports.

Migration guide

Before (deprecated):

import strawberry
from datetime import datetime

EpochDateTime = strawberry.scalar(
    datetime,
    serialize=lambda v: int(v.timestamp()),
    parse_value=lambda v: datetime.fromtimestamp(v),
)


@strawberry.type
class Query:
    created: EpochDateTime

After:

import strawberry
from typing import NewType
from datetime import datetime
from strawberry.schema.config import StrawberryConfig

EpochDateTime = NewType("EpochDateTime", datetime)


@strawberry.type
class Query:
    created: datetime


schema = strawberry.Schema(
    query=Query,
    config=StrawberryConfig(
        scalar_map={
            EpochDateTime: strawberry.scalar(
                name="EpochDateTime",
                serialize=lambda v: int(v.timestamp()),
                parse_value=lambda v: datetime.fromtimestamp(v),
            )
        }
    ),
)
