Méthode sqlalchemy.orm.Query.with_session

Signature de la méthode with_session

def with_session(self, session) 

Description

with_session.__doc__

Return a :class:`_query.Query` that will use the given
        :class:`.Session`.

        While the :class:`_query.Query`
        object is normally instantiated using the
        :meth:`.Session.query` method, it is legal to build the
        :class:`_query.Query`
        directly without necessarily using a :class:`.Session`.  Such a
        :class:`_query.Query` object, or any :class:`_query.Query`
        already associated
        with a different :class:`.Session`, can produce a new
        :class:`_query.Query`
        object associated with a target session using this method::

            from sqlalchemy.orm import Query

            query = Query([MyClass]).filter(MyClass.id == 5)

            result = query.with_session(my_session).one()
