Question

我正在尝试弄清楚如何获取我已调用我的Approve视图的数据，以便在进行任何更改后回发。到目前为止，我尝试的事情要么抛出错误，要么消除已删除/无关联的数据。

这是我的ViewModel：

    public class SurplusRequest
{
    public int PickUpID { get; set; }

    [DisplayName("First Name:")]
    public string EmployeeFN { get; set; }

    [DisplayName("Last Name:")]
    public string EmployeeLN { get; set; }

    [DisplayName("Phone:")]
    [DataType(DataType.PhoneNumber)]
    [RegularExpression(@"^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$", ErrorMessage = "Not a valid Telephone Number")]
    public string EmployeePhone { get; set; }

    [DisplayName("Request Date:")]
    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",
        ApplyFormatInEditMode = true)]
    public DateTime? RequestDate { get; set; }

    [DisplayName("Department:")]
    public string Department { get; set; }

    [DisplayName("Pick Up Requested By:")]
    public string PURequestedBy { get; set; }

    [DisplayName("Requested Pick Up Date:")]
    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",
        ApplyFormatInEditMode = true)]
    public DateTime? PURequestedDate { get; set; }

    [DisplayName("Division Manager:")]
    public string DivisionHead { get; set; }

    [DisplayName("Approval Date:")]
    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",
        ApplyFormatInEditMode = true)]
    public DateTime? DivisionHeadDate { get; set; }

    [DisplayName("Surplus Manager:")]
    public string SurplusManager { get; set; }

    [DisplayName("Surplus Approval Date:")]
    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",
        ApplyFormatInEditMode = true)]
    public DateTime? SurplusManagerDate { get; set; }

    [DisplayName("Financial Officer:")]
    public string FinancialOfficer { get; set; }

    [DisplayName("Financal Approval Date:")]
    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",
        ApplyFormatInEditMode = true)]
    public DateTime? FinancialOfficerDate { get; set; }


    public PickUpRequest Details { get; set; }
    public List<SurplusItem> SurplusItems { get; set; }
    public IQueryable<SurplusItem> SItems { get; set; }
}

        }
        if (model == null)
        {
            return HttpNotFound();
        }

        return View(model);
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Approvals(int? id, SurplusRequest SR)
    {
        var model = new SurplusRequest
        {
            Details = db.PickUpRequests.Find(id),
            SItems = db.SurplusItems.Where(s => s.PickUpID == id)
        };


        //SurplusRequest SItems = db.SurplusItems.Where(s => s.PickUpID == id);
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        if (model == null)
        {
            return HttpNotFound();
        }

        if (!ModelState.IsValid)
        {
            return View(model);
        }

        db.Entry(model.Details).State = EntityState.Modified;

        foreach (var i in model.SItems)
        {
            db.Entry(model.SItems).State = EntityState.Modified;
        }
        db.SaveChanges();
        return RedirectToAction("SubmittedRequests");

    }

我开始认为我的问题可能与我试图使用我的IQueryable发布SurplusItem数据回来是问题或事实我只是以不同的方式发回它们在一起。

任何建议都会有所帮助。感谢

Answer 1

将这些视图放在表单下。

 @using (Html.BeginForm())
        {
          //All your view here
        }

您在视图模型上所做的任何更改都将自动绑定并反映您的表单帖子。

Answer 2

让我们解决您的问题

第一个cince你没有提供我认为你没有的整个视图表格标签

 @using (Html.BeginForm())
    {

    }

现在如果你有这个，你就会得到你应该

的错误

然后你错过了antiforgerytocken

@AntiForgeryTocken();

在表单中

现在，因为你正在使用

，所以需要这种防伪装置帖子中的

[ValidateAntiForgeryToken]属性

我想这应该做

====更新======

我想我得到了你的问题配偶

如果它的jsut简单回发然后尝试改变你的动作方法，就像这样

 public ActionResult Approvals SurplusRequest SR,int? id null)

我不确定你是否在使用int？id，因为它是一个强类型视图，它只接受模型本身而不是其他参数

发布编辑ViewModel数据
