Méthode flask.Blueprint.record_once

Signature de la méthode record_once

def record_once(self, func: Callable) -> None 

Description

record_once.__doc__

Works like :meth:`record` but wraps the function in another
        function that will ensure the function is only called once.  If the
        blueprint is registered a second time on the application, the
        function passed is not called.
