蟒蛇。 SQL炼金术。如何解决AttributeError：in _

Question

我有以下代码：

    name = sess.query(
        table
    ).filter(
        getattr(
            table,
            [i for i in dir(table) if i == 'name'][0]).table_propherty.in_([1,2,3]),
        table.table != 'INVALID'
    ).all()
    return name

因此，当我尝试使用getattr过滤表并获取object和他的属性（例如table_propherty）时，我会遵循Traceback

Traceback (most recent call last):

    self.result = self.application(self.environ, self.start_response)
