在asp.net mvc中更新其他相关模型的属性

Question

我有两个实体 Gabarit 和 Local_Gabarit ，我有一个外键，它与那些名为 CodeBarre 的实体相关，后者是 Gabarit 即可。因此，在我的Gabarit编辑页面上，我不想编辑 Gabarit 属性，而是编辑 Local_Gabarit 中存在的相关属性，例如Armoire和Emplacement。 拜托，我需要你的帮助，谢谢:)

Gabarit模型：

 public Gabarit()
        {
            this.Demande = new HashSet<Demande>();
            this.Local_Gabarit = new HashSet<Local_Gabarit>();
            this.Mvt_Gabarit = new HashSet<Mvt_Gabarit>();
        }

        public int CodeBarre { get; set; }
        public string Designation { get; set; }
        public string Photo { get; set; }
        public string Exemplaire { get; set; }
        public Nullable<int> Produit { get; set; }
        public Nullable<int> Poste { get; set; }

        public virtual ICollection<Demande> Demande { get; set; }
        public virtual ICollection<Local_Gabarit> Local_Gabarit { get; set; }
        public virtual ICollection<Mvt_Gabarit> Mvt_Gabarit { get; set; }

Local_Gabarit模型：

public partial class Local_Gabarit
{
    public int id_local { get; set; }
    public Nullable<int> Emplacement { get; set; }
    public string Armoire { get; set; }
    public int CodeBarre { get; set; }
    public int id_demande { get; set; }
    public string InOut { get; set; }

    public virtual Demande Demande { get; set; }
    public virtual Gabarit Gabarit { get; set; }
}

GabaritViewModel：

public class GabaritViewModel
{
    public int CodeBarre { get; set; }
    public string Designation { get; set; }
    public string Photo { get; set; }
    public Nullable<int> Produit { get; set; }
    public string Exemplaire { get; set; }
    public Nullable<int> Poste { get; set; }

    public int id_local { get; set; }
    public Nullable<int> Emplacement { get; set; }
    public string Armoire { get; set; }
}

GabaritsController：

 // GET: Gabarits/Edit/5
        public ActionResult Edit(int? id)
        {

            var localrepository = new LocalGabaritRepository(db);
            var dbgabarit = gabaritrepository.GetById(id);
            var req = localrepository.Get(p => p.CodeBarre == dbgabarit.CodeBarre).SingleOrDefault();
            var armoire = req.Armoire;
            var emplacement = req.Emplacement;

            if (dbgabarit != null)
            {
                var gabarit = new GabaritViewModel()
                {
                    CodeBarre = dbgabarit.CodeBarre,
                    Designation = dbgabarit.Designation,
                    Photo = dbgabarit.Photo,
                    Exemplaire = dbgabarit.Exemplaire,
                    Poste=dbgabarit.Poste,
                    Produit=dbgabarit.Produit,
                    Emplacement=emplacement,
                    Armoire=armoire,
                };

                return View(gabarit);
            }
            else
                return HttpNotFound();
        }

        // POST: Gabarits/Edit/5
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Edit( GabaritViewModel gabarit)
        {
           var  localrepository = new LocalGabaritRepository(db);
            if (ModelState.IsValid)
            {
              var req= localrepository.Get(p => p.CodeBarre == gabarit.CodeBarre).SingleOrDefault();
              var armoire = req.Armoire;
              var emplacement = req.Emplacement;
              var idl = req.id_local;
              var idd = req.id_demande;
              var InOut = req.InOut;
              var CodeBarre = req.CodeBarre;

              var dblocal = new Local_Gabarit()
              {
                  Emplacement = emplacement,
                  Armoire = armoire,
                  id_local=idl,
                  id_demande=idd,
                  InOut=InOut,
                  CodeBarre=CodeBarre

              };
              localrepository.Update(dblocal);

            }
            return View(gabarit);
        }

我不知道我是否以正确的方式行事，但这是我试图做的事情。 谢谢。
