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:

• _orm.declarative_base()
• _orm.declared_attr
• _orm.has_inherited_table()
• _orm.synonym_for()
• _orm.as_declarative()

See Declarative Extensions for the remaining Declarative extension classes.
