我有一个简单的亲子模型

   public class ApplicationTableAndFieldsViewModel
{
    [Key]
    [Required]
    public int ParentTableID { get; set; }
    [Required]
    public string Description { get; set; }

    public List<ApplicationTableField> ApplicationTableFields { get; set; }
}

我将整个模型从控制器传递到视图没有问题：

        public ViewResult Edit(int parentTableID)
    {
        ApplicationTableAndFieldsViewModel applicationTable = repository.ApplicationTablesVM
                .FirstOrDefault(p => p.ParentTableID == parentTableID);
        ViewBag.FieldTypeList = repository.FieldTypes;

        IEnumerable<string> FieldTypeDrop = repository.FieldTypes;


        List<SelectListItem> selectList = new List<SelectListItem>();
        foreach (var c in FieldTypeDrop)
        {
            SelectListItem i = new SelectListItem();
            i.Text = c;
            i.Value = c;
            selectList.Add(i);
        }
        ViewBag.FieldTypeList = selectList;
        return …
