Как сохранить изменения в БД с помощью нескольких моделей в одном представлении в ASP.NET MVC?

---

Привет Команда

Я изо всех сил пытаюсь сохранить поля в своей БД, сначала я использовал одну модель для их сохранения, и это была(TbRegistrationForm). Теперь моя форма использует несколько моделей в одном представлении, и моя отправка не сохраняет эти поля в определении таблицы.

Что я уже пробовал:

<pre>// Controller
<pre> public ActionResult SaveRegForm()
        {
            ViewBag.Message = "Details saved successfull";
            return View(db.TrainingRegs.ToList());
        }

//GET:TrainingRegForm/Create/WebRequest.
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult SubmitRegDetails([Bind(Include= "Id, Title, FirstName, LastName, Position, Company, StreetAddress, StreetAddressLine, City, StateProvince, ZipCode,Country,Email, CellNumber, DietaryRequirement")]TrainingRegForm eNtsaTraining)
{
    this.ViewBag.SubmitRegDetails = this.SaveRegForm();

    if(ModelState.IsValid)
    {
        eNtsaTraining.Id = Guid.NewGuid();
        db.TrainingRegs.Add(eNtsaTraining);
        db.SaveChanges();
        return RedirectToAction("SaveRegForm");
    }

    // Validates when empty.
    if(ModelState.IsValid)
    {
        return RedirectToAction("SaveRegForm");
    }
    return View(eNtsaTraining);
}

// Модельный

namespace eNtsaRegistrationTraining.Models
{
    public class TrainingRegForm
    {
        [Key]
        public Guid? Id { get; set; }
        public string Title { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Position { get; set; }
        public string Company { get; set; }

        public string StreetAddress { get; set; }

        public string StreetAddressLine { get; set; }

        public string City { get; set; }
        public string StateProvince { get; set; }

        public int ZipCode { get; set; }

        public string Country { get; set; }

        public string Email { get; set; }

        [Required(ErrorMessage = "This field is required")]
        [DataType(DataType.PhoneNumber)]
        public string CellNumber { get; set; }
        public string DietaryRequirement { get; set; }
    }


    public class RegViewAndRoleViewModel
    {
        public DietViewModel DietMain { get; set; }

        public TrainingRegForm RegForm { get; set; }

       public DropDownViewModel ListCountries { get; set; }
        public RegistrationTrainingForm HomeModel { get; set; }
        public RoleViewModel RoleViewModelData { get; set; }

       
    }
