映射一个平面视图类层次结构中的功能NHibernate [英] Mapping a flat view to class hierarchy in fluent nHibernate

问题描述

我正在开发一个应用程序使用的比赛结果/时间等。
，有一个模型 我有一个模型，它看起来是这样的：

I'm developing an app that has a model using race results / times etc..
I've got a model that looks something like:

public class Competitor
{
    public virtual int ID { get; set; }
    public virtual string Name { get; set; }
    public virtual DateTime DateOfBirth { get; set; }
}

public class Event
{
    public virtual int ID { get; set; }
    public virtual string Name { get; set; }
    public virtual string Description { get; set; }
}

public class Result
{
    public virtual int ID { get; set; }
    public virtual decimal ResultTime { get; set; }
    public virtual Competitor Competitor { get; set; }
    public virtual Event Event { get; set; }
}

在我的数据库，我只能访问其重新present数据的平面视图查看。这看起来是这样的：

In my database, I only have access to Views which represent a "flat" view of the data. This would look something like:

vResult

ResultID
ResultTime
CompetitorID
CompetitorName
CompetitorDateOfBirth
事件ID
事件名称
EventDescription

ResultID
ResultTime
CompetitorID
CompetitorName
CompetitorDateOfBirth
EventID
EventName
EventDescription

所以，我想，以避免一个是完全符合上面的扁平化架构类（如果可能）

So, I'm trying to avoid having a class that matches the above "flat" schema entirely (if possible)

是否可能映射此与功能NHibernate？

Is it possibly to map this with Fluent nHibernate?

修改 -
值得一提的是，数据访问将是只读

EDIT-
It's worth mentioning, data access will be read only

推荐答案

正如上述评论表明，它的确是组件的解决了这一点。

As comments above indicated, it was indeed Component that solved this.

随着我的结果映射类下面的几行：

Along the lines of the following in my ResultMap class:

Component(x => x.Event, m =>
            {
                m.Map(x => x.ID).Column("EventID");
                m.Map(x => x.Name).Column("EventName");
                m.Map(x => x.Description).Column("EventDescription");
            });
