Question

我非常确定我的大脑是朋友，这是我明天早上会笑的事情，但不幸的是我仍然坚持这一部分并且正在寻求帮助。

我有一个ViewModel：

public class HousingDetailsViewModel : AppViewModel
{
    DataContext db = new DataContext();

    public List<string> units { get; set; }
    public List<AvailableHousing> availableHousings { get; set; }
    public Person person { get; set; }
    public OccupiedHousing currentHousing { get; set; }
    public OccupiedHousing newHousing;

    public HousingDetailsViewModel(int? id)
    {
            units = db.AvailableHousings.OrderBy(ah => ah.Unit).Select(h => h.Unit).Distinct().ToList();
            availableHousings = db.AvailableHousings.Where(h => h.Available == true).OrderBy(h => h.Bed)
                                                                                    .OrderBy(h => h.Room).ToList();
            currentHousing = db.OccupiedHousing.Include(o => o.AvailableHousing)
                                               .Include(o => o.Person).Where(o => o.PersonID == id && o.CurrentHousing == true).FirstOrDefault();
            person = db.Persons.Find(id);
            newHousing = new OccupiedHousing();
    }
}

此视图的控制器方法：

public ActionResult Details(int? id)
{
    return View(new HousingDetailsViewModel(id));
}

[HttpPost]
public ActionResult Move(OccupiedHousing newHousing, int? personID)
{
    newHousing.PersonID = personID;
    newHousing.DateArrived = DateTime.Now;
    newHousing.CurrentHousing = true;
    newHousing.AvailableHousingID = housingID;
    db.OccupiedHousings.Add(newHousing);
    db.SaveChanges();


    return RedirectToAction("Index", new HousingViewModel());
}

我的表单适用于我的所有字段，除了1，这是可用的房屋ID。我试过设置一个隐藏的值。我设置了一个断点，我设置了隐藏字段的值，我看着它发生了变化，但它没有进入控制器。所以我将其更改为表单提交，并尝试将其作为路由值捕获并且也无法正常工作。我不知所措，谁能看到我出错的地方？

编辑：添加视图

@model AppName.ViewModels.HousingDetailsViewModel
@{
    ViewBag.Title = "Housing Details";
}

@Html.BeginForm("Move", "Housing", new { personID = @Model.person.ID }, FormMethod.Post, new { })
<script>
    function setID(id) {
        $('#HiddenHousingID').val(id);
        $('#HiddenSubmit').click();
    }
</script>

路线：

@Html.BeginForm("Move", "Housing", new { personID = @Model.person.ID , housingID=  @Model.newHousing.AvailableHousingID}, FormMethod.Post, new { })

无法通过viewmodel从视图传递值到控制器
