- Fix type hint for ``get_or_404`` return value. :pr:`1208`
- Fix type hints for pyright (used by VS Code Pylance extension). :issue:`1205`
```
### 3.0.3
```
-------------
Released 2023-01-31
- Show helpful errors when mistakenly using multiple ``SQLAlchemy`` instances for the
same app, or without calling ``init_app``. :pr:`1151`
- Fix issue with getting the engine associated with a model that uses polymorphic
table inheritance. :issue:`1155`
```
### 3.0.2
```
-------------
Released 2022-10-14
- Update compatibility with SQLAlchemy 2. :issue:`1122`
```
### 3.0.1
```
-------------
Released 2022-10-11
- Export typing information instead of using external typeshed definitions.
:issue:`1112`
- If default engine options are set, but ``SQLALCHEMY_DATABASE_URI`` is not set, an
invalid default bind will not be configured. :issue:`1117`
```
### 3.0.0
```
-------------
Released 2022-10-04
- Drop support for Python 2, 3.4, 3.5, and 3.6.
- Bump minimum version of Flask to 2.2.
- Bump minimum version of SQLAlchemy to 1.4.18.
- Remove previously deprecated code.
- The session is scoped to the current app context instead of the thread. This
requires that an app context is active. This ensures that the session is cleaned up
after every request.
- An active Flask application context is always required to access ``session`` and
``engine``, regardless of if an application was passed to the constructor.
:issue:`508, 944`
- Different bind keys use different SQLAlchemy ``MetaData`` registries, allowing
tables in different databases to have the same name. Bind keys are stored and looked
up on the resulting metadata rather than the model or table.
- ``SQLALCHEMY_DATABASE_URI`` does not default to ``sqlite:///:memory:``. An error is
raised if neither it nor ``SQLALCHEMY_BINDS`` define any engines. :pr:`731`
- Configuring SQLite with a relative path is relative to ``app.instance_path`` instead
of ``app.root_path``. The instance folder is created if necessary. :issue:`462`
- Added ``get_or_404``, ``first_or_404``, ``one_or_404``, and ``paginate`` methods to
the extension object. These use SQLAlchemy's preferred ``session.execute(select())``
pattern instead of the legacy query interface. :issue:`1088`
- Setup methods that create the engines and session are renamed with a leading
underscore. They are considered internal interfaces which may change at any time.
- All parameters to ``SQLAlchemy`` except ``app`` are keyword-only.
- Renamed the ``bind`` parameter to ``bind_key`` and removed the ``app`` parameter
from various ``SQLAlchemy`` methods.
- The extension object uses ``__getattr__`` to alias names from the SQLAlchemy
package, rather than copying them as attributes.
- The extension object is stored directly as ``app.extensions["sqlalchemy"]``.
:issue:`698`
- The session class can be customized by passing the ``class_`` key in the
``session_options`` parameter. :issue:`327`
- ``SignallingSession`` is renamed to ``Session``.
- ``Session.get_bind`` more closely matches the base implementation.
- Model classes and the ``db`` instance are available without imports in
``flask shell``. :issue:`1089`
- The ``CamelCase`` to ``snake_case`` table name converter handles more patterns
correctly. If model that was already created in the database changed, either use
Alembic to rename the table, or set ``__tablename__`` to keep the old name.
:issue:`406`
- ``Model`` ``repr`` distinguishes between transient and pending instances.
:issue:`967`
- A custom model class can implement ``__init_subclass__`` with class parameters.
:issue:`1002`
- ``db.Table`` is a subclass instead of a function.
- The ``engine_options`` parameter is applied as defaults before per-engine
configuration.
- ``SQLALCHEMY_BINDS`` values can either be an engine URL, or a dict of engine options
including URL, for each bind. ``SQLALCHEMY_DATABASE_URI`` and
``SQLALCHEMY_ENGINE_OPTIONS`` correspond to the ``None`` key and take precedence.
:issue:`783`
- Engines are created when calling ``init_app`` rather than the first time they are
accessed. :issue:`698`
- ``db.engines`` exposes the map of bind keys to engines for the current app.
- ``get_engine``, ``get_tables_for_bind``, and ``get_binds`` are deprecated.
- SQLite driver-level URIs that look like ``sqlite:///file:name.db?uri=true`` are
supported. :issue:`998, 1045`
- SQLite engines do not use ``NullPool`` if ``pool_size`` is 0.
- MySQL engines use the "utf8mb4" charset by default. :issue:`875`
- MySQL engines do not set ``pool_size`` to 10.
- MySQL engines don't set a default for ``pool_recycle`` if not using a queue pool.
:issue:`803`
- ``Query`` is renamed from ``BaseQuery``.
- Added ``Query.one_or_404``.
- The query class is applied to ``backref`` in ``relationship``. :issue:`417`
- Creating ``Pagination`` objects manually is no longer a public API. They should be
created with ``db.paginate`` or ``query.paginate``. :issue:`1088`
- ``Pagination.iter_pages`` and ``Query.paginate`` parameters are keyword-only.
- ``Pagination`` is iterable, iterating over its items. :issue:`70`
- Pagination count query is more efficient.
- ``Pagination.iter_pages`` is more efficient. :issue:`622`
- ``Pagination.iter_pages`` ``right_current`` parameter is inclusive.
- Pagination ``per_page`` cannot be 0. :issue:`1091`
- Pagination ``max_per_page`` defaults to 100. :issue:`1091`
- Added ``Pagination.first`` and ``last`` properties, which give the number of the
first and last item on the page. :issue:`567`
- ``SQLALCHEMY_RECORD_QUERIES`` is disabled by default, and is not enabled
automatically with ``app.debug`` or ``app.testing``. :issue:`1092`
- ``get_debug_queries`` is renamed to ``get_recorded_queries`` to better match the
config and functionality.
- Recorded query info is a dataclass instead of a tuple. The ``context`` attribute is
renamed to ``location``. Finding the location uses a more inclusive check.
- ``SQLALCHEMY_TRACK_MODIFICATIONS`` is disabled by default. :pr:`727`
- ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` is deprecated. It can cause various design issues
that are difficult to debug. Call ``db.session.commit()`` directly instead.
:issue:`216`
```
### 2.5.1
```
-------------
Released 2021-03-18
- Fix compatibility with Python 2.7.
```
### 2.5.0
```
-------------
Released 2021-03-18
- Update to support SQLAlchemy 1.4.
- SQLAlchemy ``URL`` objects are immutable. Some internal methods have changed to
return a new URL instead of ``None``. :issue:`885`
```
### 2.4.4
```
-------------
Released 2020-07-14
- Change base class of meta mixins to ``type``. This fixes an issue caused by a
regression in CPython 3.8.4. :issue:`852`
```
### 2.4.3
```
-------------
Released 2020-05-26
- Deprecate ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` as it can cause various design issues
that are difficult to debug. Call ``db.session.commit()`` directly instead.
:issue:`216`
```
### 2.4.2
```
-------------
Released 2020-05-25
- Fix bad pagination when records are de-duped. :pr:`812`
```
### 2.4.1
```
-------------
Released 2019-09-24
- Fix ``AttributeError`` when using multiple binds with polymorphic models. :pr:`651`
```
### 2.4.0
```
-------------
Released 2019-04-24
- Drop support for Python 2.6 and 3.3. :pr:`687`
- Address SQLAlchemy 1.3 deprecations. :pr:`684`
- Make engine configuration more flexible. Added the ``engine_options`` parameter and
``SQLALCHEMY_ENGINE_OPTIONS`` config. Deprecated the individual engine option config
keys ``SQLALCHEMY_NATIVE_UNICODE``, ``SQLALCHEMY_POOL_SIZE``,
``SQLALCHEMY_POOL_TIMEOUT``, ``SQLALCHEMY_POOL_RECYCLE``, and
``SQLALCHEMY_MAX_OVERFLOW``. :pr:`684`
- ``get_or_404()`` and ``first_or_404()`` now accept a ``description`` parameter to
control the 404 message. :issue:`636`
- Use ``time.perf_counter`` for Python 3 on Windows. :issue:`638`
- Add an example of Flask's tutorial project, Flaskr, adapted for Flask-SQLAlchemy.
:pr:`720`
