Signature de la méthode apply_driver_hacks

def apply_driver_hacks(self, app, sa_url, options) 

Description

apply_driver_hacks.__doc__

This method is called before engine creation and used to inject
        driver specific hacks into the options.  The `options` parameter is
        a dictionary of keyword arguments that will then be used to call
        the :func:`sqlalchemy.create_engine` function.

        The default implementation provides some saner defaults for things
        like pool sizes for MySQL and sqlite.  Also it injects the setting of
        `SQLALCHEMY_NATIVE_UNICODE`.

        .. versionchanged:: 2.5
            Returns ``(sa_url, options)``. SQLAlchemy 1.4 made the URL
            immutable, so any changes to it must now be passed back up
            to the original caller.
