多対多の関係を使用しようとしていますが、私は顧客を編集して表示することに成功しましたが、私は作成できません。 私の例では、1人の顧客（クライアント）が1つ以上の社会に参加することができます。 Visual Studioを使用して段階的に、私の値が私の最初の「作成」機能に渡すことができないことに気付きました。私は正常にフィールドを取得したいが、POSTすることはできません。 マイClientController：ASP.netで多対多の関係を使用する
namespace CRM.ViewModels
{
public class ClientViewModel
{
public Client Client { get; set; }
public IEnumerable<SelectListItem> AllSocietes { get; set; }
private List<int> selectedSociete;
public List<int> SelectedSociete
{
get
{
if (selectedSociete == null)
{
selectedSociete = Client.Societes.Select(m => m.ID).ToList();
}
return selectedSociete;
}
set { selectedSociete = value; }
}
}
}
そして最後に、私のビューを：：
私は私のコントローラで使用していnamespace CRM.Models
{
public class Client : Personne // Héritage de la classe Personne
{
public Client()
{
this.Societes= new HashSet<Societe>();
}
[Column("StatutClientID")]
public int StatutClientID { get; set; }
public string Fonction { get; set; } // TODO:Type enum
[Display(Name = "Est Actif ?")]
public bool IsActif { get; set; }
[DataType(DataType.MultilineText)]
public string Commentaire { get; set; }
public string Fax { get; set; }
public virtual StatutClient StatutClient { get; set; }
public virtual ICollection<Societe> Societes { get; set; }
override public string ToString()
{
return this.Prenom+" "+this.Nom;
}
}
}
私のクラスのviewmodels：
public ActionResult Create()
{
var cli = new ClientViewModel
{
Client = new Client()
};
var allSocietesList = db.Societes.ToList();
cli.AllSocietes = allSocietesList.Select(o => new SelectListItem
{
Text = o.Nom,
Value = o.ID.ToString()
});
ViewBag.StatutClientID = new SelectList(db.StatutClients, "ID", "Designation");
return View(cli);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(ClientViewModel client) //Here is where the value dosesn't pass, "client" value is null;
{
if (ModelState.IsValid)
{
var cliToAdd = new Client();
var updatedSocietes = new HashSet<int>(client.SelectedSociete);
foreach (Societe societe in db.Societes)
{
if (updatedSocietes.Contains(societe.ID))
{
cliToAdd.Societes.Add((societe));
}
}
db.Clients.Add(cliToAdd);
db.Entry(cliToAdd).State = System.Data.Entity.EntityState.Added;
db.SaveChanges();
return RedirectToAction("Index");
}
ViewBag.StatutClientID = new SelectList(db.StatutClients, "ID", "Designation", client.Client.StatutClientID);
return View(client);
}
は今私のクライアントモデルが登場

ViewBag.Title = "Create";

（私の社会モデル（名前 "societe"）、それが何であるか知りたいが、ここから問題が出てこない場合は、スキップすることができます）。私の問題は、私の英語や他の何かの理解することは容易ではない場合は、ちょうど:)
EDITを尋ねる https://www.codeproject.com/articles/702890/mvc-entity-framework-and-many-to-many-relation
：首尾よく編集し、表示するための
namespace CRM.Models
{
public class Societe
{
public Societe()
{
this.Clients = new HashSet<Client>();
}
public int ID { get; set; }
public string Nom { get; set; }
//[Required] //TODO: renseigner adresse dans les societes de l'initializer
[Display(Name = "Lieu")]
public int LieuID { get; set; }
public string Adresse { get; set; }
public int Km { get; set; }
public string Temps { get; set; }
public bool IsActif { get; set; }
public virtual Lieu Lieu { get; set; }
public virtual ICollection<Affaire> Affaires { get; set; }
public virtual ICollection<Client> Clients { get; set; }
}
}
は、私はそのチュートリアルに従っ：私の編集機能は100％機能です：
public ActionResult Edit(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
var clientViewModel = new ClientViewModel
{
Client = db.Clients.Include(i => i.Societes).First(i => i.ID == id)
};
if (clientViewModel.Client == null)
return HttpNotFound();
var allSocietesList = db.Societes.ToList();
clientViewModel.AllSocietes = allSocietesList.Select(o => new SelectListItem
{
Text = o.Nom,
Value = o.ID.ToString()
});
ViewBag.StatutClientID = new SelectList(db.StatutClients, "ID", "Designation", clientViewModel.Client.StatutClientID);
return View(clientViewModel);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(ClientViewModel clientView)
{
if (clientView == null) return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
if (ModelState.IsValid)
{
var clientToUpdate = db.Clients
.Include(i => i.Societes).First(i => i.ID == clientView.Client.ID);
if (TryUpdateModel(clientToUpdate, "Client", new string[] { "Fonction", "Commentaire", "Nom", "Prenom", "Telephone", "Mobile", "Fax", "Mail", "IsActif", "StatutClientID" }))
{
// var newJobTags = db.Societes.Where(
// m => clientView.SelectedSociete.Contains(m.ID)).ToList();
var updatedSocietes = new HashSet<int>(clientView.SelectedSociete);
foreach (Societe societe in db.Societes)
{
if (!updatedSocietes.Contains(societe.ID))
{
clientToUpdate.Societes.Remove(societe);
}
else
{
clientToUpdate.Societes.Add((societe));
}
}
db.Entry(clientToUpdate).State = System.Data.Entity.EntityState.Modified;
db.SaveChanges();
}
return RedirectToAction("Index");
}
ViewBag.StatutClientID = new SelectList(db.StatutClients, "ID", "Designation", clientView.Client.StatutClientID);
return View(clientView);
}
