У меня есть представление "создать" в скаффолде, которое, когда я пытаюсь создать новую запись, возвращает ошибку: System.Web.Mvc.WebViewPage<TModel>.Model.get returned null. Еще до того, как я нажал "сохранить".
Моя модель:
namespace Itucation.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity.Spatial;
[Table("jobcoach")]
public partial class jobcoach
{
public int kursist_id { get; set; }
//[Column(TypeName = "text")]
public string note { get; set; }
[Key]
public int jobcoach_note_id { get; set; }
[Column("status")]
//[StringLength(50)]
[Display(Name = "Status")]
public string status { get; set; }
[Column(TypeName = "date")]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Success dato")]
public DateTime? succesDato { get; set; }
public int? AntalSamtaler { get; set; }
public virtual kursister kursister { get; set; }
}
}
Мой контроллер:
// GET: jobcoach/Create
public ActionResult Create(int? id)
{
ViewBag.kursist_id = new SelectList(db.kursister, "kursist_id", "fornavn");
ViewBag.status = new SelectList(db.JobcoachStatus, "status", "status");
ViewBag.ID = id;
ViewBag.kursist = (from k in db.kursister
where k.kursist_id == id
select k);
//var jc = db.jobcoach.Where(u => u.kursist_id == id).ToList().FirstOrDefault();
var jc = db.jobcoach.Where(r => r.kursist_id == id).ToList().FirstOrDefault();
if (jc == null)
{
// param is not set
}
else
{
return RedirectToAction("Edit/" + jc.jobcoach_note_id);
}
return View();
}
// POST: jobcoach/Create

public ActionResult Create([Bind(Include = "jobcoach_note_id,kursist_id,note,status,succesDato, AntalSamtaler")] jobcoach jobcoach)
{
if (ModelState.IsValid)
{
//Brugernavn (current user) skal også indsættes
jobcoach.note = jobcoach.note + " Af " + User.Identity.Name + " - " + DateTime.Now.ToString();
db.jobcoach.Add(jobcoach);
db.SaveChanges();
return RedirectToAction("Index");
}

Я бы ожидал «пустой» вид со всеми полями ввода, где я мог бы ввести дату и нажать «Сохранить». Вместо этого я получаю ошибку.
Ошибка возникает в строке: @Html.ValidationMessageFor(model => model.note, "", new { @class = "text-danger" }).
Я не могу понять это. Я вижу много вопросов, касающихся этой ошибки, но ни один из них не подходит для моей проблемы.
Буду очень признателен за любую помощь.
