Signature de la méthode filter_by

def filter_by(self, **kwargs) 

Description

filter_by.__doc__

Apply the given filtering criterion to a copy
        of this :class:`_query.Query`, using keyword expressions.

        e.g.::

            session.query(MyClass).filter_by(name = 'some name')

        Multiple criteria may be specified as comma separated; the effect
        is that they will be joined together using the :func:`.and_`
        function::

            session.query(MyClass).\
                filter_by(name = 'some name', id = 5)

        The keyword expressions are extracted from the primary
        entity of the query, or the last entity that was the
        target of a call to :meth:`_query.Query.join`.

        .. seealso::

            :meth:`_query.Query.filter` - filter on SQL expressions.
