Changelog

Version 2.3.3

Fix "AttributeError: 'NoneType' object has no attribute 'info'", when using polymorphic models. (#651)

Version 2.3.2

Released on October 11, 2017

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

Version 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)

Version 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)

Version 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)

Version 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.

Version 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.
