我已经搜索过网络并堆叠溢出以寻找我的问题的答案,但我没有运气。
基本上我有一个模型,它有2个相同对象和其他对象的引用。当我向模型插入记录时,属性未加载,因此我尝试了Context.Attach函数没有运气。我还尝试查询现有记录,但对象仍未附加
这是我的模特
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Key]
public Guid TripID { get; set; }
[Required]
[Range(1, 999999, ErrorMessage = "Total Distance can only be a positive number non-zero")]
public double TotalDistance { get; set; }
[Required]
public double AmountDue { get; set; }
[Required]
public TripPaymentType PaymentType { get; set; }
[Required]
public TripStatus CurrentStatus { get; set; }
[ForeignKey("TripTypeId")]
public TripType TripType { get; set; }
[Required]
public Guid TripTypeId { get; set; }
[Required]
public DateTime TransactionDate { get; set; }
[Required]
public Guid CustomerID { get; set; }
[ForeignKey("CustomerID")]
public UserInfo Customer { get; set; }
public Guid? DriverID { get; set; }
[ForeignKey("DriverID")]
public UserInfo Driver { get; set; }
配置单个对象多个引用
modelBuilder.Entity<TripHistory>()
.HasRequired(th => th.Customer)
.WithMany()
.WillCascadeOnDelete(false);
modelBuilder.Entity<TripHistory>()
.HasOptional(th => th.Driver)
.WithMany()
.WillCascadeOnDelete(false);
非常感谢任何帮助
答案 0 :(得分:0)
供将来参考,
出于某种原因,即使通过使用.Include()方法启用延迟加载,我也必须强制加载对象。
