跟着教程操作，却无法级联插入

[supersdar]

 static void Main(string[] args)
 {
     var f = DB.Sqlite;
     var order = new Order
     {
         Field2 = "field2",
         Extdata = new OrderExt { Field3 = "field3" },
         Details = new List<OrderDetail>
         {
             new OrderDetail { Field4 = "field4_01", Extdata = new OrderDetailExt { Field5 = "field5_01" } },
             new OrderDetail { Field4 = "field4_02", Extdata = new OrderDetailExt { Field5 = "field5_02" } },
             new OrderDetail { Field4 = "field4_03", Extdata = new OrderDetailExt { Field5 = "field5_03" } },
         }
     };
     f.GetRepository<Order>().Insert(order); 
 }

class Order
{
    [Column(IsIdentity = true)]
    public int Id { get; set; }
    public string Field2 { get; set; }

    public OrderExt Extdata { get; set; }

    [Navigate(nameof(OrderDetail.OrderId))]
    public List<OrderDetail> Details { get; set; }
}
class OrderExt
{
    [Key]
    public int OrderId { get; set; }
    public string Field3 { get; set; }

    public Order Order { get; set; }
}
class OrderDetail
{
    [Column(IsIdentity = true)]
    public int Id { get; set; }
    public int OrderId { get; set; }
    public string Field4 { get; set; }

    public OrderDetailExt Extdata { get; set; }
}
class OrderDetailExt
{
    [Key]
    public int OrderDetailId { get; set; }
    public string Field5 { get; set; }

    public OrderDetail OrderDetail { get; set; }
}

数据库中只多出一个Order表。请问我哪里做错了？

repo.DbContextOptions.EnableCascadeSave = true

文档有这个

[supersdar]

  class BId
  {
      [Column(IsIdentity = true, IsPrimary = true)]
      public int Id { get; set; }
  }
  //ManyToOne
  class Member: BId
  {
      public string Name { get; set; }
      public int GroupId { get; set; }

      #region 这个类的匹配Id
      [Navigate(nameof(GroupId))]
      public Group Group { get; set; } 
      #endregion
     
  }
  //OneToMany
  class Group : BId
  {
      public string GroupName { get; set; }

      #region Many的匹配Id
      [Navigate(nameof(Member.Id))]
      public List<User> Users { get; set; }
      #endregion
  }

 var f = DB.Sqlite;
 Member r = new Member() {
      Name="mm",
       Group=new Group() { GroupName="GName" }
 };
 var ro = f.GetRepository<Member>();
 ro.DbContextOptions.EnableCascadeSave = true;
 ro.Insert(r);           
 Console.WriteLine( r.Group.Id);

为什么我这么写后，Fsql只能在数据库里写入User，Group却不会连带写入

[2881099]

文档说了，从下往上不支持

只能从上级往下级，或者一对一

推荐看这里的机制

[2881099]

这些机制主要从安全方面考虑，Group不止属于一个 User，修改 User 时把其他 User 的 Group 也一起修改，不合理
