marshmallow-annotations 2.4.0

marshmallow-annotations allows you to create marshmallow schema from classes with annotations on them

from marshmallow_annotations import AnnotationSchema
from .music import Album, Artist

class AlbumScheme(AnnotationSchema):
    class Meta:
        target = Album
        register_as_scheme = True


class ArtistScheme(AnnotationSchema):
    class Meta:
        target = Artist
        register_as_scheme = True


scheme = ArtistScheme()
scheme.dump(
    Artist(
        id=1, name="Abominable Putridity",
        albums=[
            Album(
                id=1,
                name="The Anomalies of Artificial Origin"
            )
        ]
    )
)

# {
#     "albums": [
#         {
#             "id": 1,
#             "name": "The Anomalies of Artificial Origin"
