Signature de la méthode populate_existing

def populate_existing(self) 

Description

populate_existing.__doc__

Return a :class:`_query.Query`
        that will expire and refresh all instances
        as they are loaded, or reused from the current :class:`.Session`.

        As of SQLAlchemy 1.4, the :meth:`_orm.Query.populate_existing` method
        is equivalent to using the ``populate_existing`` execution option at
        the ORM level. See the section :ref:`orm_queryguide_populate_existing`
        for further background on this option.
