我有一个复杂的视图模型,我正在将其传递给创建视图。当我在页面上输入数据并提交后,模型为空。子对象中的字段和“test”字段都是空的。为什么会这样?
public class ContactIncident
{
[Key]
public int Id { get; set; }
[DataType(DataType.MultilineText)]
public string Description { get; set; }
[Display(Name = "Incident Date")]
[DataType(DataType.Date)]
public DateTime? IncidentDateTime { get; set; }
[Display(Name = "Follow Up Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
[DataType(DataType.Date)]
public DateTime? FollowUpDate { get; set; }
}
public class IncidentManager
{
public ContactIncident Incident { get; set; }
public string Test { get; set; }
}
public ActionResult Create(int? id)
{
IncidentManager im = new IncidentManager();
ContactIncident ci = new ContactIncident();
ci.IncidentDateTime = DateTime.Now;
ci.FollowUpDate = DateTime.Now.AddDays(14);
im.Incident = ci;
return View(im);
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(IncidentManager im)
{
if (ModelState.IsValid)
{
ContactIncident ci = new ContactIncident();
ci.IncidentDateTime = incident.Incident.IncidentDateTime;
ci.Description = im.Incident.Description;
return RedirectToAction("Index");
}
return View(incident);
}
视图:
@model MyApp.Web.ViewModels.IncidentManager
@{
ViewBag.Title = "Edit Incident";
}
<h4>@ViewBag.Title</h4>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal well">
@Html.ValidationSummary(true)
@Html.EditorFor(model=>model.Test)
<div class="row">
<div class="col-md-2">
@Html.LabelFor(model => model.Incident.IncidentDateTime)
</div>
<div class="col-md-2">
@Html.DisplayFor(model => model.Incident.IncidentDateTime)
</div>
</div>
<div class="row">
<div class="col-md-2">
@Html.LabelFor(model => model.Incident.Description)
</div>
<div class="col-md-10">
@Html.EditorFor(model => model.Incident.Description, new { htmlAttributes = new { @class = "form-control", rows = "5" }, })
</div>
<div class="col-md-2">
@Html.LabelFor(model => model.Incident.FollowUpDate)
</div>
<div class="col-md-2">
@Html.EditorFor(model => model.Incident.FollowUpDate, new { htmlAttributes = new { @class = "form-control"}, })
</div>
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Save" class="btn btn-default" />
</div>
</div>
}
ci.IncidentDateTime = incident.Incident.IncidentDateTime;
是一个打字错误,实际上应该是ci.IncidentDateTime = im.Incident.IncidentDateTime;
。同样的,return View(incident);
也应该是return View(im);
(你的代码无法编译)。除此之外,你的代码工作正常,尽管IncidentDateTime
将是null
,因为你没有为它创建表单输入。 - user3559349
