Signature de la fonction dynamic_loader

def dynamic_loader(argument, **kw) 

Description

dynamic_loader.__doc__

Construct a dynamically-loading mapper property.

    This is essentially the same as
    using the ``lazy='dynamic'`` argument with :func:`relationship`::

        dynamic_loader(SomeClass)

        # is the same as

        relationship(SomeClass, lazy="dynamic")

    See the section :ref:`dynamic_relationship` for more details
    on dynamic loading.
