Méthode sqlalchemy.orm.registry.dispose

Signature de la méthode dispose

def dispose(self, cascade=False) 

Description

dispose.__doc__

Dispose of all mappers in this :class:`_orm.registry`.

        After invocation, all the classes that were mapped within this registry
        will no longer have class instrumentation associated with them. This
        method is the per-:class:`_orm.registry` analogue to the
        application-wide :func:`_orm.clear_mappers` function.

        If this registry contains mappers that are dependencies of other
        registries, typically via :func:`_orm.relationship` links, then those
        registries must be disposed as well. When such registries exist in
        relation to this one, their :meth:`_orm.registry.dispose` method will
        also be called, if the :paramref:`_orm.registry.dispose.cascade` flag
        is set to ``True``; otherwise, an error is raised if those registries
        were not already disposed.
