Fonction immediateload - module sqlalchemy.orm

Signature de la fonction immediateload

def immediateload(*keys) 

Description

immediateload.__doc__

Indicate that the given attribute should be loaded using
    an immediate load with a per-attribute SELECT statement.

    The load is achieved using the "lazyloader" strategy and does not
    fire off any additional eager loaders.

    The :func:`.immediateload` option is superseded in general
    by the :func:`.selectinload` option, which performs the same task
    more efficiently by emitting a SELECT for all loaded objects.

    This function is part of the :class:`_orm.Load` interface and supports
    both method-chained and standalone operation.
