Méthode sqlalchemy.orm.MapperProperty.post_instrument_class

Signature de la méthode post_instrument_class

def post_instrument_class(self, mapper) 

Description

post_instrument_class.__doc__

Perform instrumentation adjustments that need to occur
        after init() has completed.

        The given Mapper is the Mapper invoking the operation, which
        may not be the same Mapper as self.parent in an inheritance
        scenario; however, Mapper will always at least be a sub-mapper of
        self.parent.

        This method is typically used by StrategizedProperty, which delegates
        it to LoaderStrategy.init_class_attribute() to perform final setup
        on the class-bound InstrumentedAttribute.
