please use this approach in the case of a type like ENUM which requires special
schema-level steps:
class MyEnum(sa.types.TypeDecorator, sa.types.SchemaType):
impl = postgresql.ENUM
def _set_parent(self, column):
self.impl._set_parent(column)
class Test(Base):
__tablename__ = 'test'
id = sa.Column(sa.Integer, primary_key=True)
enum_column = sa.Column(MyEnum('1', '2', '3', name='my_enum_type'))
engine = sa.create_engine('postgresql://scott:tiger@localhost/test', echo=True)
Base.metadata.create_all(engine)
