Fluent Nhibernate的嵌套子類

Question

我見過如何使用舊的子類語法做到這一點的例子，但沒有使用較新的：SubclassMap語法。

基本上，我有一個表中有多個鑑別器，需要弄清楚如何用FNH做到這一點。

感謝， 山姆

我們有一個基類用戶和許多派生類從學習者，評估人員，經理，管理員等

這裏是中userMap

public class UserMap : ClassMap<User> 
{ 
    public UserMap() 
    { 
     this.Id(x => x.Id); 

     this.Map(x => x.Active); 

     this.Component(
      x => x.Address, 
      m => 
      { 
       m.Map(x => x.Address1).Length(512); 
       m.Map(x => x.Address2); 
       m.Map(x => x.Address3); 
       m.Map(x => x.Address4); 
       m.Map(x => x.City); 
       m.Map(x => x.County); 
       m.Map(x => x.PostCode); 
       m.References(x => x.Country); 
      }); 

     this.References(x => x.CreatedBy); 

     this.Map(x => x.CreatedDate).Not.Nullable(); 

     this.Map(x => x.DeletedDate); 

     this.References(x => x.DeletedBy); 

     this.Map(x => x.Email); 

     this.Map(x => x.Fax); 

     this.Map(x => x.FirstName); 

     this.References(x => x.Gender); 

     this.Map(x => x.LastName); 

     this.Map(x => x.LoginName).UniqueKey("ui_loginName").Not.Nullable(); 

     this.Map(x => x.MiddleName); 

     this.Map(x => x.Password); 

     this.DiscriminateSubClassesOnColumn("className").Length(64); 
    } 
} 

和經理的一個例子

public class ManagerMap : SubclassMap<Manager> 
{ 
    #region Constructors and Destructors 

    /// <summary> 
    /// Initializes a new instance of the <see cref="ManagerMap"/> class. 
    /// </summary> 
    public ManagerMap() 
    { 
     this.HasManyToMany(x => x.Organisation) 
      .ParentKeyColumn("userId") 
      .ChildKeyColumn("organisationId") 
      .Table("UserOrganisations"); 

     this.HasMany(x => x.Learners) 
      .KeyColumn("managerId") 
      .AsBag(); 
    } 

    #endregion 
} 

希望會幫助你。
