如何使用FluentNHibernate在ManyToMany生成的表中添加额外的字段

问题描述

我有2个实体用户和颜色。一个用户可能与多种颜色相关联，一种颜色可能与多个用户相关联。
我使用FluentNHibernate autopersistence模型来生成数据库。现在我必须添加到生成的表UserToColor（UserId，ColorId）还有一个额外的字段'CreatedOn'，我该如何完成，这是否与流利nhibernate完成？

解决方案

NHibernate不支持这个。最好的解决方法是创建一个额外的类作为一个链接表，并有从你的每个现有的类多对一的关系。

I have 2 entities Users and Colors. One user may be associated with multiple colors, and one color may be associated with multiple users.I use FluentNHibernate autopersistence model to generate the database. Now I have to add to the generated table UserToColor(UserId,ColorId) also an extra field 'CreatedOn', how can I accomplish and is this accomplishable with fluent-nhibernate?

解决方案

NHibernate doesn't support this. The best workaround is to create an extra class as a link table, and have a many to one relationship to it from each of your existing classes.
