SQLite InsertWithChildren还是UpdateWithChildren?

我有两个表,我试图使用InsertWithChildren将记录插入到子表中,遗憾的是它没有按预期工作。

public class Schedule
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    public DateTime Date { get; set; }
    public DateTime ShiftStart { get; set; }
    public DateTime ShiftEnd { get; set; }
    public string ShiftNotes { get; set; }
    public string Company { get; set; }
    public string Color { get; set; }
    public string Visibility { get; set; }
    [OneToMany(CascadeOperations = CascadeOperation.All)]
    public List<Punches> Punches { get; set; }
}

public class Punches
{
    [PrimaryKey, AutoIncrement]
    public int Id { get; set; }
    [ForeignKey(typeof(Schedule))]
    public int ScheduleId { get; set; }
    public string Company { get; set; }
    public DateTime Date { get; set; }
    public DateTime Time { get; set; }
    public string Mode { get; set; }
    //public TimeSpan Duration { get; set; }

}

这是2个表格。插入是如何发生的,首先我将一条记录插入到Schedules表中,然后我在稍后添加该记录的打孔。我可以将记录插入到Schedules表中,稍后当我在schedule表上添加与该记录相关的打孔时,它只会被覆盖,它不会添加到它。 这是我将记录添加到计划表的方式:

Schedule newSchedule = new Schedule()
                {
                    Date = Convert.ToDateTime(tblDate.Text),
                    ShiftStart = Convert.ToDateTime(btnShiftStart.Content.ToString()),
                    ShiftEnd = Convert.ToDateTime(btnShiftEnd.Content.ToString()),
                    ShiftNotes = tbAddNotes.Text,
                    Company = App.company,
                    Color = App.color,
                    Visibility = "Collapsed",
                    //Punches = new List<Punches>({,
                };
                App.db.InsertWithChildren(newSchedule, true);

通过这种方式进入Punches表:

var sch = App.db.Find<Schedule>(s => s.Id == theSelectedShift.Id);
                List<Punches> newPunch = new List<Punches>();
                newPunch.Add(new Punches()
                    {
                        Company = theSelectedShift.Company,
                        Date = theSelectedShift.Date,
                        Time = DateTime.Now,
                        Mode = mode,
                    });
                App.db.InsertAllWithChildren(newPunch);

                sch.Punches = newPunch;
                App.db.UpdateWithChildren(sch);

这里发生的是,它将数据作为Schedules表中现有记录的子项插入Punches表。第二次当我将另一行添加到Punches表中时,它也是Schedules表中同一行的子项,当我用GetWithChildren方法提取它时,我没有看到作为子记录添加的2条记录。 / p>

请指教!
