Flask-marshmallow

*******************

Bug fixes:

* Fix compatibility with marshmallow-sqlalchemy<0.22.0 (:issue:`189`).
Thanks :user:`PatrickRic` for reporting.

Other changes:

* Remove unused ``flask_marshmallow.sqla.SchemaOpts``.

*******************

* *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 <https://marshmallow-sqlalchemy.readthedocs.io/en/latest/changelog.html>`_
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``.

.. code-block:: python

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
