问题描述

当我调用Save()方法引发异常"Can not directly save a child object"时，如何保存子对象?

When I call the Save() method throw exception "Can not directly save a child object", how to save a child object?

推荐答案

我之所以回答，是因为我很好奇CSLA是什么.在16.3秒内，我学会了:

I''m answering this because I was curious what CSLA was. In 16.3 seconds I learned:

子对象的确切定义是将其作为其父对象的一部分持久保存.那是您不能保存子对象的一种奇特的说法，因为这是CSLA的设计方式.

即使您(并且可以)取消围绕保存子对象的常规保护措施，也可能会使父对象感到困惑，这会导致其他问题.

如果您需要直接保存此对象，则它是根对象，而不是子对象.如果是这种情况，则该对象不能包含在另一个对象中，它必须是独立的.-CSLA的创建者Rockford Lhotka

The very definition of a child object is that it is persisted as part of its parent. That''s a fancy way of saying that you can''t save a child object, because that''s how CSLA is designed.

Even if you defeat the normal protections around saving a child object (and you can), you''d confuse the parent object and that would cause other problems.

If you need to save this object directly, then it is a root object, not a child object. And if that''s the case, then the object can''t be contained by another object, it must stand alone. -- Rockford Lhotka, creator of CSLA
