流利的NHibernate：如何创建循环的一对一映射？ [英] Fluent NHibernate: How to create circular one-to-one mapping?

问题描述

  public class AdminUser 
 {
 public virtual int Id {get;组; } 
 public virtual string UserName {get;组; } 
 public virtual string Password {get;组; } 
 public virtual bool IsLocked {get;组; } 
 public virtual AdminUser Creator {get;组; } 
 public virtual DateTime CreationDate {get;组; } 
} 
 
 public class AdminUserMapping：ClassMap< AdminUser> 
 {
 public AdminUserMapping（）
 {
 Id（c => c.Id）.GeneratedBy.Native（）; 
 Map（c => c.UserName）.Not.Nullable（）; 
 Map（c => c.Password）.Not.Nullable（）; 
 Map（c => c.IsLocked）.Not.Nullable（）; 
 Map（c => c.CreationDate）.Not.Nullable（）; 
 // HasOne< AdminUser>（...？）
} 
} 
  

你好，我有类似上面，我想创建一个一对一的映射造物主属性在同一个类上

我怎么能

解决方案

试试这个：

  References（x => x.Creator）; 
  

确保您的表格上有一个名为Creator_Id的列。如果你不这样做，你可以使用：

$ p $ 引用（x => x.Creator）.Column（YourColumnName ）


public class AdminUser
{
    public virtual int Id { get; set; }
    public virtual string UserName { get; set; }
    public virtual string Password { get; set; }
    public virtual bool IsLocked { get; set; }
    public virtual AdminUser Creator { get; set; }
    public virtual DateTime CreationDate { get; set; }
}

public class AdminUserMapping : ClassMap<AdminUser>
{
    public AdminUserMapping()
    {
        Id(c => c.Id).GeneratedBy.Native();
        Map(c => c.UserName).Not.Nullable();
        Map(c => c.Password).Not.Nullable();
        Map(c => c.IsLocked).Not.Nullable();
        Map(c => c.CreationDate).Not.Nullable();
        //HasOne<AdminUser>(... ?) 
    }
}

Hi i have class like above, and i want to create one-to-one mapping for "Creator" property on same class

how can i do this?

解决方案

Try this:

References(x => x.Creator);

Make sure that you have a column named Creator_Id on your table. If you don't, you can use:

References(x => x.Creator).Column("YourColumnName")
