Description

__init__.__doc__

Construct a new :class:`.sessionmaker`.

        All arguments here except for ``class_`` correspond to arguments
        accepted by :class:`.Session` directly.  See the
        :meth:`.Session.__init__` docstring for more details on parameters.

        :param bind: a :class:`_engine.Engine` or other :class:`.Connectable`
         with
         which newly created :class:`.Session` objects will be associated.
        :param class\_: class to use in order to create new :class:`.Session`
         objects.  Defaults to :class:`.Session`.
        :param autoflush: The autoflush setting to use with newly created
         :class:`.Session` objects.
        :param autocommit: The autocommit setting to use with newly created
         :class:`.Session` objects.
        :param expire_on_commit=True: the
         :paramref:`_orm.Session.expire_on_commit` setting to use
         with newly created :class:`.Session` objects.

        :param info: optional dictionary of information that will be available
         via :attr:`.Session.info`.  Note this dictionary is *updated*, not
         replaced, when the ``info`` parameter is specified to the specific
         :class:`.Session` construction operation.

        :param \**kw: all other keyword arguments are passed to the
         constructor of newly created :class:`.Session` objects.
