Question

Я попытался добавить элемент из модели Device в модель WorkSheet.Сначала я создаю таблицу с устройствами, и я не знаю, как код кнопки для добавления выбранного устройства в рабочий лист.Модель устройства:

public class Device
{
    public int DeviceId { get; set; }
    public string ShortcutName { get; set; }
    public string SerialNumber { get; set; }
    public string PrimarySupply { get; set; }
    public string SecondarySupply { get; set; }


    [DataType(DataType.Date, ErrorMessage = "Niepoprawny format daty")]
    [DisplayFormat(DataFormatString = "{0:yyyy}", ApplyFormatInEditMode = true)]
    public System.DateTime ProductionYear { get; set; }

    [DataType(DataType.Date, ErrorMessage = "Niepoprawny format daty")]
    [DisplayFormat(DataFormatString = "{0:yyyy}", ApplyFormatInEditMode = true)]
    public System.DateTime AssemblyDate { get; set; }

    [DataType(DataType.Date, ErrorMessage = "Niepoprawny format daty")]
    [DisplayFormat(DataFormatString = "{0:dd.MM.yyyy}", ApplyFormatInEditMode = true)]
    public System.DateTime LastReviewDate { get; set; }


    [ForeignKey("Installation")]
    public int InstallationId { get; set; }
    public virtual Installation Installation { get; set; }

    [ForeignKey("BatteryPack")]
    public int BatteryPackId { get; set; }
    public virtual BatteryPack BatteryPack { get; set; }

    [ForeignKey("Load")]
    public int LoadId { get; set; }
    public virtual Load Load { get; set; }

    [ForeignKey("OperatingMode")]
    public int OperatingModeId { get; set; }
    public virtual OperatingMode OperatingMode { get; set; }

    [ForeignKey("DeviceModel")]
    public int DeviceModelId { get; set; }
    public virtual DeviceModel DeviceModel { get; set; }

    [ForeignKey("DeviceType")]
    public int DeviceTypeId { get; set; }
    public virtual DeviceType DeviceType { get; set; }

    public virtual ICollection<WorkSheet> WorkSheets { get; set; }
}

Модель рабочего листа:

public class WorkSheet
{
    public WorkSheet()
    {

    }
    public int? WorkSheetId { get; set; }

    [ForeignKey("Device")]
    public int DeviceId { get; set; }
    public virtual Device Device { get; set; }
}

Контроллер:

public ActionResult WorkSheetAddDevice()
    {
        var devices = db.Devices.ToList();
        var lista = devices.OrderBy(s => s.Installation.ShortcutName).Select(s => new DeviceListElement()
        {
            DeviceId = s.DeviceId,
            ShortcutName = s.ShortcutName,
            SerialNumber = s.SerialNumber,
            PrimarySupply = s.PrimarySupply,
            SecondarySupply = s.SecondarySupply,
            ProductionYear = s.ProductionYear,
            AssemblyDate = s.AssemblyDate,
            LastReviewDate = s.LastReviewDate,
            InstallationId = s.InstallationId,
            Installation = s.Installation.ShortcutName,
            BatteryPackId = s.BatteryPackId,
            BatteryPack = s.BatteryPack.ShortcutName,
            LoadId = s.LoadId,
            Load = s.Load.Name,
            OperatingModeId = s.OperatingModeId,
            OperatingMode = s.OperatingMode.Name,
            DeviceModelId = s.DeviceModelId,
            DeviceModel = s.DeviceModel.Name,
            DeviceTypeId = s.DeviceTypeId,
            DeviceType = s.DeviceType.Name,
            WorkSheets = s.WorkSheets.Count(),
        });
        return View(lista);
    }

Просмотр:

@model IEnumerable<ProjectE.Models.ViewModels.DeviceListElement>

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.Installation)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.ShortcutName)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.DeviceModel)
        </th>
        <th></th>
    </tr>

    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.Installation)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.ShortcutName)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.DeviceModel)
            </td>
            <td>
                <input type="submit" value="Create" class="btn btn-default"/>
            </td>
        </tr>
    }

</table>

Этоработает, но как создать кнопку для добавления устройства на лист в этом представлении?
