[fluent-nhib] How can I map component as foreign key?

[Oğuzhan EREN]

Hi,

I need map TenantId (component of Account) as Foreign Key (Tenant). Db must 
know TenantId is primary key of Tenant. When I add new record to Account, 
nhibernate or db must validate TenantId value exists on Tenants table.

I don't want keep Reference, only Foreign Key 

Session.Save(new Account(new TenantId("guid-of-exists-tenant"),new 
AccountId("guid"))


public class Entity<TId>
{
    public virtual TId {get;set;}
}

public class TenantId
{
    public virtual Guid Id {get;set;}
}

public class Tenant
    : Entity<TenantId>
{
    public string Name {get;set;}
}

public class AccountId
{
    public virtual Guid Id {get;set;}   
}

public class Account
    : Entity<AccountId>
{
    public Account(TenantId tenantId,AccountId accountId)
    {
        TenantId = tenantId;
        Id= accountId;
    }

    public TenantId TenantId {get;set;}
    public string AccountName {get;set;}
}

public class TenantMap
{
    public TenantMap()
    {
        CompositeId<TenantId>(t => t.Id).KeyProperty(x => x.Id);
Map(x=>x.Name);
    }
}

public class AccountMap
{
    public AccountMap()
    {
        CompositeId<AccountId>(t => t.Id).KeyProperty(x => x.Id);
        Component(x=>x.TenantId,m=>{
m.Map(x=>x.Id).Not.Nullable();
});
        Map(x => x.AccountName).Not.Nullable();
    }
}
