手動管理在城堡的ActiveRecord

連接表我有這樣定義了兩個連接類：手動管理在城堡的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; } 
    }

當我連接存儲到一個客戶，我需要設置狀態爲好。所以我試圖做到這一點：

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); 
    }

這會在ABJoin中創建兩個條目，第一個是狀態集，第二個沒有。如果我不將這些對象添加到它們各自的列表中，它就會起作用。但是，直到當前會話關閉並且實例從數據庫重新下載之後，鏈接纔會反映在這些對象中。

那麼，有沒有一種方法可以在創建鏈接時設置狀態，還可以使當前對象保持有效並保持最新狀態？

當你的關係表（在你的情況下，「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; } 
}
