Declarative API

API Reference

Changed in version 1.4: The fundamental structures of the declarative system are now part of SQLAlchemy ORM directly. For these components see:

  • declarative_base()

  • declared_attr

  • has_inherited_table()

  • synonym_for()

  • sqlalchemy.orm.as_declarative()

See Declarative Extensions for the remaining Declarative extension classes.
