StaleObjectStateException ich bin immer ein Benutzerkonto auf Update, die

Question

gerade erstellt wurde So beschäftige ich mich mit dem Fehler:

Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [Domain.Entities.General.Shipping#0]

, wenn der Benutzer will, um ihre Lieferadresse in meiner Anwendung aktualisieren.

-Controller

var shippingToAdd = new Shipping 
       { 
        UserId = newUserId, 
        FirstName = model.FirstName, 
        LastName = model.LastName, 
        Address = model.ShippingStreet, 
        SteApt = model.ShippingAptSte, 
        City = model.ShippingCity, 
        State = model.ShippingState, 
        Zip = model.ShippingZip, 
        Country = shippingCountryId, 
       }; 
       UserManagerService.UpdateShipping(shippingToAdd); 

UserManagerService

public static ISession Context { get; set; } 

     public UserManagerService(ISession context) 
     { 
      Context = context; 
     } 

    public static int UpdateShipping(Shipping shipping) 
    { 
     using (ITransaction transaction = Context.BeginTransaction()) 
     { 
      Context.Update(shipping); 
      transaction.Commit(); 
      return 0; //Right Here is where StaleObjectStateException occurs 
     } 
    } 

Gibt es trotzdem, um die Sperre zu heben, kurz bevor der Commit()? Oder was ist der beste Weg, um eine Sperre im Allgemeinen zu lösen?

Answer 1

Ich verstehe nicht, warum Sie Update aufrufen(), wenn Sie ein neues Objekt hinzufügen möchten. Wollten Sie ISession.Save() oder ISession.SaveOrUpdate() verwenden?
