Changelog

0.15.0 (2023-04-05)

  • Only support Python>=3.6, marshmallow>=3.0.0, and marshmallow-sqlalchemy>=0.28.2

  • Add support for python3.11

  • Backwards-incompatible: URLFor and AbsoluteURLFor now do not accept parameters for flask.url_for as top-level parameters. They must always be passed in the values dictionary, as explained in the v0.14.0 changelog.

Bug fixes:

  • Address distutils deprecation warning in Python 3.10 (#242). Thanks @GabrielLins64 for the PR.

0.14.0 (2020-09-27)

  • Add values argument to URLFor and AbsoluteURLFor for passing values to flask.url_for.

This prevents unrelated parameters from getting passed (#52, #67). Thanks @AlrasheedA for the PR.

Deprecation:

  • Passing params to flask.url_for via URLFor’s and AbsoluteURLFor’s constructor params is deprecated. Pass values instead.

0.13.0 (2020-06-07)

Bug fixes:

  • Fix compatibility with marshmallow-sqlalchemy<0.22.0 (#189). Thanks @PatrickRic for reporting.

0.12.0 (2020-04-26)

  • Breaking change: ma.ModelSchema and ma.TableSchema are removed, since these are deprecated upstream.

Warning

It is highly recommended that you use the newer ma.SQLAlchemySchema and ma.SQLAlchemyAutoSchema classes instead of ModelSchema and TableSchema. See the release notes for marshmallow-sqlalchemy 0.22.0 for instructions on how to migrate.

If you need to use ModelSchema and TableSchema for the time being, you’ll need to import these directly from marshmallow_sqlalchemy.

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_marshmallow import Marshmallow

app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:////tmp/test.db"

db = SQLAlchemy(app)
ma = Marshmallow(app)

# flask-marshmallow<0.12.0


class AuthorSchema(ma.ModelSchema):
    class Meta:
        model = Author


# flask-marshmallow>=0.12.0 (recommended)


class AuthorSchema(ma.SQLAlchemyAutoSchema):
    class Meta:
        model = Author
        load_instance = True


# flask-marshmallow>=0.12.0 (not recommended)

from marshmallow_sqlalchemy import ModelSchema


class AuthorSchema(ModelSchema):
    class Meta:
        model = Author
        sql_session = db.session
