[pyup-bot]

This PR updates Flask-SQLAlchemy from 1.0 to 2.3.2.

Changelog

2.3.2

-------------

Released on October 11, 2017

- Don't mask the parent table for single-table inheritance models. (`561`_)

.. _561: https://github.com/mitsuhiko/flask-sqlalchemy/pull/561

2.3.1

-------------

Released on October 5, 2017

- If a model has a table name that matches an existing table in the metadata,
use that table. Fixes a regression where reflected tables were not picked up
by models. (`551`_)
- Raise the correct error when a model has a table name but no primary key.
(`556`_)
- Fix ``repr`` on models that don't have an identity because they have not been
flushed yet. (`555`_)
- Allow specifying a ``max_per_page`` limit for pagination, to avoid users
specifying high values in the request args. (`542`_)
- For ``paginate`` with ``error_out=False``, the minimum value for ``page`` is
1 and ``per_page`` is 0. (`558`_)

2.3.0

-------------

Released on September 28, 2017

- Multiple bugs with ``__tablename__`` generation are fixed. Names will be
generated for models that define a primary key, but not for single-table
inheritance subclasses. Names will not override a ``declared_attr``.
``PrimaryKeyConstraint`` is detected. (`541`_)
- Passing an existing ``declarative_base()`` as ``model_class`` to
``SQLAlchemy.__init__`` will use this as the base class instead of creating
one. This allows customizing the metaclass used to construct the base.
(`546`_)
- The undocumented ``DeclarativeMeta`` internals that the extension uses for
binds and table name generation have been refactored to work as mixins.
Documentation is added about how to create a custom metaclass that does not
do table name generation. (`546`_)
- Model and metaclass code has been moved to a new ``models`` module.
``_BoundDeclarativeMeta`` is renamed to ``DefaultMeta``; the old name will be
removed in 3.0. (`546`_)
- Models have a default ``repr`` that shows the model name and primary key.
(`530`_)
- Fixed a bug where using ``init_app`` would cause connectors to always use the
``current_app`` rather than the app they were created for. This caused issues
when multiple apps were registered with the extension. (`547`_)

2.2

-----------

Released on February 27, 2017, codename Dubnium

- Minimum SQLAlchemy version is 0.8 due to use of ``sqlalchemy.inspect``.
- Added support for custom ``query_class`` and ``model_class`` as args
to the ``SQLAlchemy`` constructor. (`328`_)
- Allow listening to SQLAlchemy events on ``db.session``. (`364`_)
- Allow ``__bind_key__`` on abstract models. (`373`_)
- Allow ``SQLALCHEMY_ECHO`` to be a string. (`409`_)
- Warn when ``SQLALCHEMY_DATABASE_URI`` is not set. (`443`_)
- Don't let pagination generate invalid page numbers. (`460`_)
- Drop support of Flask < 0.10. This means the db session is always tied to
the app context and its teardown event. (`461`_)
- Tablename generation logic no longer accesses class properties unless they
are ``declared_attr``. (`467`_)

2.1

-----------

Released on October 23rd 2015, codename Caesium

- Table names are automatically generated in more cases, including
subclassing mixins and abstract models.
- Allow using a custom MetaData object.
- Add support for binds parameter to session.

2.0

-----------

Released on August 29th 2014, codename Bohrium

- Changed how the builtin signals are subscribed to skip non Flask-SQLAlchemy
sessions.  This will also fix the attribute error about model changes
not existing.
- Added a way to control how signals for model modifications are tracked.
- Made the ``SignallingSession`` a public interface and added a hook
for customizing session creation.
- If the ``bind`` parameter is given to the signalling session it will no
longer cause an error that a parameter is given twice.
- Added working table reflection support.
- Enabled autoflush by default.
- Consider ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` harmful and remove from docs.
