# Before
from marshmallow_sqlalchemy import ModelSchema, field_for

from . import models


class ArtistSchema(ModelSchema):
    class Meta:
        model = models.Artist

    id = field_for(models.Artist, "id", dump_only=True)
    created_at = field_for(models.Artist, "created_at", dump_only=True)


# After
from marshmallow_sqlalchemy import SQLAlchemySchema, auto_field

from . import models


class ArtistSchema(SQLAlchemyAutoSchema):
    class Meta:
        model = models.Artist

    id = auto_field(dump_only=True)
    created_at = auto_field(dump_only=True)
  • Add load_instance option to configure deserialization to model instances (:issue:`193`, :issue:`270`).
  • Add include_relationships option to configure generation of marshmallow fields for relationship properties (:issue:`98`). Thanks :user:`dusktreader` for the suggestion.

Deprecations:

  • ModelSchema and TableSchema are deprecated, since SQLAlchemyAutoSchema has equivalent functionality.
# Before
from marshmallow_sqlalchemy import ModelSchema, TableSchema

from . import models


class ArtistSchema(ModelSchema):
    class Meta:
        model = models.Artist


class AlbumSchema(TableSchema):
    class Meta:
        table = models.Album.__table__


# After
from marshmallow_sqlalchemy import SQLAlchemyAutoSchema

from . import models


class ArtistSchema(SQLAlchemyAutoSchema):
    class Meta:
        model = models.Artist
        include_relationships = True
        load_instance = True


class AlbumSchema(SQLAlchemyAutoSchema):
    class Meta:
        table = models.Album.__table__
  • Passing info={"marshmallow": ...} to SQLAlchemy columns is deprecated, as it is redundant with the auto_field functionality.

Other changes:

  • Backwards-incompatible: fields_for_model does not include relationships by default. Use fields_for_model(..., include_relationships=True) to preserve the old behavior.

0.21.0 (2019-12-04)

0.20.0 (2019-12-01)

  • Add support for mysql.DATETIME and mysql.INTEGER type (:issue:`204`).
  • Add support for postgresql.CIDR type (:issue:`183`).
  • Add support for postgresql.DATE and postgresql.TIME type.

Thanks :user:`evelyn9191` for the PR.

0.19.0 (2019-09-05)

  • Drop support for Python 2.7 and 3.5 (:issue:`241`).
  • Drop support for marshmallow<2.15.2.
  • Only support sqlalchemy>=1.2.0.

0.18.0 (2019-09-05)

Features:

Note: This is the last release to support Python 2.7 and 3.5.

0.17.2 (2019-08-31)

Bug fixes:

  • Fix error handling when passing an invalid type to Related (:issue:`223`). Thanks :user:`heckad` for reporting.
  • Address DeprecationWarning raised when using Related with marshmallow 3 (:pr:`243`).

0.17.1 (2019-08-31)

Bug fixes:

  • Add marshmallow_sqlalchemy.fields.Nested field that inherits its session from its schema. This fixes a bug where an exception was raised when using Nested within a ModelSchema (:issue:`67`). Thanks :user:`nickw444` for reporting and thanks :user:`samueljsb` for the PR.

User code should be updated to use marshmallow-sqlalchemy's Nested instead of marshmallow.fields.Nested.

# Before
from marshmallow import fields
from marshmallow_sqlalchemy import ModelSchema


class ArtistSchema(ModelSchema):
    class Meta:
        model = models.Artist


class AlbumSchema(ModelSchema):
    class Meta:
        model = models.Album

    artist = fields.Nested(ArtistSchema)


# After
from marshmallow import fields
from marshmallow_sqlalchemy import ModelSchema
from marshmallow_sqlalchemy.fields import Nested


class ArtistSchema(ModelSchema):
    class Meta:
        model = models.Artist


class AlbumSchema(ModelSchema):
    class Meta:
        model = models.Album

    artist = Nested(ArtistSchema)
