手动管理在城堡的ActiveRecord

连接表我有这样定义了两个连接类：手动管理在城堡的ActiveRecord

[ActiveRecord] 
    public class Store : ActiveRecordBase<Store> { 
     [PrimaryKey] 
     public int ID { get; set; } 

     [HasAndBelongsToMany(Table = "StoreCustJoin", 
          ColumnKey = "storeID", 
          ColumnRef = "customerID")] 
     public IList<Customer> customers { get; set; } 
    } 

    [ActiveRecord] 
    public class Customer : ActiveRecordBase<Customer> { 
     [PrimaryKey] 
     public int ID { get; set; } 

     [HasAndBelongsToMany(Table = "Join", 
          ColumnKey = "customerID", 
          ColumnRef = "storeID", 
          inverse = true)] 
     public IList<Store> stores { get; set; } 
    } 

    [ActiveRecord] 
    public class Join : ActiveRecordBase<Join> { 
     [PrimaryKey] 
     public int ID { get; set; } 

     [BelongsTo("storeID")] 
     public Store store { get; set; } 

     [BelongsTo("customerID")] 
     public Customer customer { get; set; } 

     [Property] 
     public int Status { get; set; } 
    }

当我连接存储到一个客户，我需要设置状态为好。所以我试图做到这一点：

public void SetLink(Store theStore, Customer theCustomer, int status) { 
     var link = new Join() 
         { 
          Status = status, 
          store = theStore, 
          customer = theCustomer 
         }; 
     theStore.customers.Add(theCustomer); 
     theCustomer.stores.Add(theStore); 
    }

这会在ABJoin中创建两个条目，第一个是状态集，第二个没有。如果我不将这些对象添加到它们各自的列表中，它就会起作用。但是，直到当前会话关闭并且实例从数据库重新下载之后，链接才会反映在这些对象中。

那么，有没有一种方法可以在创建链接时设置状态，还可以使当前对象保持有效并保持最新状态？

当你的关系表（在你的情况下，“加入”表）具有比FKS它涉及表等附加字段，使用[HasMany]代替[HasAndBelongsToMany]，即：

[ActiveRecord] 
public class Store : ActiveRecordBase<Store> { 
    [PrimaryKey] 
    public int ID { get; set; } 

    [HasMany] 
    public IList<Join> customers { get; set; } 
} 

[ActiveRecord] 
public class Customer : ActiveRecordBase<Customer> { 
    [PrimaryKey] 
    public int ID { get; set; } 

    [HasMany] 
    public IList<Join> stores { get; set; } 
}
