如何descending在SQLAlchemy查询中使用ORDER BY ,如下所示？

此查询有效,但按升序返回:

query = (model.Session.query(model.Entry)
        .join(model.ClassificationItem)
        .join(model.EnumerationValue)
        .filter_by(id=c.row.id)
        .order_by(model.Entry.amount) # This row :)
        )

如果我尝试:

.order_by(desc(model.Entry.amount))

然后我得到:NameError: global name 'desc' is not defined.
