流利code映射一个IDictionary＆LT; SomeEntity，INT和GT ;? [英] Fluent code for mapping an IDictionary<SomeEntity, int>?

问题描述

我试图找出如何映射用流利的1.0 RTM一个IDictionary属性。

I'm trying to figure out how to map an IDictionary property in fluent 1.0 RTM.

这是我的理解这相当于一个三重关联。

From my understanding this translates to a ternary association.

例如：

class Bar
{
    public IDictionary<SomeEntity, int> Foo {get; set;}
}

Bar.hbm.xml将包含：

Bar.hbm.xml would then contain:

<map name="Foo" table="BarFooTable">
    <key column="..."/>
    <index-many-to-many class="SomeEntity" column="SomeEntity_Id"/>
    <element column="Value" type="int"/>
</map>

我会怎么得流利NHibernate的写入产生这种XML映射？

What would I have to write in fluent nhibernate to produce this mapping xml?

这里感兴趣的一点是，关键是实体类型而值是值类型。 （编辑：至少，这似乎从各种其他的例子和问题上的计算器左右浮动或谷歌群体，这是值，值或键键区分开来）

The point of interest here is that the key is an entity type while the value is a value type. (edit: At least, this seems to distinguish itself from the various other examples and questions floating around on stackoverflow or google groups, which are value-value or key-key)

经过多次实验，我可以产生一个映射的IDictionary＆LT; SomeEntity，SomeEntity＆GT; （纯实体类型）：

After much experimentation I can produce a mapping for an IDictionary<SomeEntity,SomeEntity> (pure entity types):

HasManyToMany(x => x.Foo)
        .AsMap("Key")
        .AsTernaryAssociation("Key2", "Value")
        ; 

我也能产生一个映射的的IDictionary＆LT; INT，INT＆GT; （纯值类型）：

HasMany(x => x.Foo)
    .AsMap<int>("Key")
    .Element("Value")
    ;

我甚至可以得到一些方法来制造用于映射的的IDictionary＆LT; INT，someValue中），但没有一个NHibernate的接受

I can even get some way to producing a mapping for an IDictionary<int, SomeValue), although none that NHibernate will accept.

但我无法弄清楚如何产生一个的IDictionary℃的映射; someValue中，INT＆GT; 这就是我想要的。有人可以提供一些建议吗？

But I cannot figure out how to produce a mapping for an IDictionary<SomeValue, int> which is what I want. Can someone provide some tips?

推荐答案

我碰到了同样的问题，却高兴不起来，混合流畅和HBM映射。你可以看到我修复这里。

I ran into the same problem, and wasn't happy with mixing fluent and hbm mappings. You can see my fix here.
