Constructeur sqlalchemy.orm.scoped_session.__init__

Signature de la constructeur __init__

def __init__(self, session_factory, scopefunc=None) 

Description

__init__.__doc__

Construct a new :class:`.scoped_session`.

        :param session_factory: a factory to create new :class:`.Session`
         instances. This is usually, but not necessarily, an instance
         of :class:`.sessionmaker`.
        :param scopefunc: optional function which defines
         the current scope.   If not passed, the :class:`.scoped_session`
         object assumes "thread-local" scope, and will use
         a Python ``threading.local()`` in order to maintain the current
         :class:`.Session`.  If passed, the function should return
         a hashable token; this token will be used as the key in a
         dictionary in order to store and retrieve the current
         :class:`.Session`.
