Solve the following python programming problem given the following code:
def commit_when_no_transaction(f) : 
    'Decorator for committing changes when the instance session is
not in a transaction.' 
    def _(self, * args, **kwargs) : 
        r = f (self, * args, ** kwargs) 
        return (self.session.add (self) if (self.session is not None) else r) 
_.__name__ = _.__name__ 
    _.__doc__ = f.__doc__ 
    return _ 

    
    

    Fix the buggy line: _.__name__ = _.__name__
