NHibernate审计 - PostInsert不工作

Question

我的应用程序具有以下实体:

public class User
{
    public virtual int UserID { get; set; }
    public virtual string UserName { get; set; }
    public virtual IList<UserLog> Log { get; private set; }

    public User()
    {
        Log = new List<UserLog>();
    }
}

public class UserLog
{
    public virtual int UserLogID { get; set; }
    public virtual User User { get; set; }
    public virtual string UserName { get; set; }
    public virtual DateTime DateCreated { get; set; }
}

使用以下流畅的映射:

public class UserMap : ClassMap<User>
{
    public UserMap()
    {
        Table("Users");
        Id(x => x.UserID);
        Map(x => x.UserName);
        HasMany(x => x.Log)
            .KeyColumn("UserID")
            .OrderBy("DateCreated")
            .Inverse()
            .Cascade.All();
    }
}

public class UserLogMap : ClassMap<UserLog>
{
    public UserLogMap()
    {
        Table("UsersLog");
        Id(x => x.UserLogID);
        References(x => x.User, "UserID");
        Map(x => x.UserName);
        Map(x => x.DateCreated);
    }
}

UsersLog表只记录对用户所做的任何更改.我正在尝试使用NHibernate事件侦听器自动挂钩.我已经设置了我的配置,成功调用了以下两种方法:

public void OnPostInsert(PostInsertEvent @event)
{
    if (@event.Entity is User)
        InsertLog(@event.Entity);
}

public void OnPostUpdate(PostUpdateEvent @event)
{
    if (@event.Entity is User)
        InsertLog(@event.Entity);
}

编辑(这是InsertLog方法):

private void InsertLog(object entity)
{
    var context = ServiceLocator.Current.GetInstance<IDataContext>();
    var user = (User)entity;
    context.Repository<UserLog>().Insert(new UserLog
    {
        User = user,
        UserName = user.UserName,
        DateCreated = DateTime.UtcNow
    }); // Insert calls ISession.SaveOrUpdate(entity)
}

当我更新记录时,日志成功插入,但是当我插入记录时,我收到一条错误,告诉我UserLog表中的UserID不能为空.我玩了几个不同的变化,但似乎没有任何作用.

如果有人能告诉我如何做到这一点,我真的很感激.谢谢

解决方案发布在问题评论中 我只需要使用:

@event.Session.GetSession(NHibernate.EntityMode.Poco).Save(...);

保存用户而不是访问存储库.
