Définition

class SessionTransaction(TransactionalContext):

Description _{[extrait de SessionTransaction.__doc__]}

A :class:`.Session`-level transaction.

    :class:`.SessionTransaction` is produced from the
    :meth:`_orm.Session.begin`
    and :meth:`_orm.Session.begin_nested` methods.   It's largely an internal
    object that in modern use provides a context manager for session
    transactions.

    Documentation on interacting with :class:`_orm.SessionTransaction` is
    at: :ref:`unitofwork_transaction`.


    .. versionchanged:: 1.4  The scoping and API methods to work with the
       :class:`_orm.SessionTransaction` object directly have been simplified.
