asp.net-mvc-3 – ASP.NET MVC 3一对多表格

public class Person
{
    public int PersonId { get; set; }
    public string Name { get; set; }
    //... additional properties
    [Required]
    public virtual ICollection<Address> Addresses { get; set; }
}
public class Address
{
    public int AddressId { get; set; }
    public string Street { get; set; }
    //... additional properties

    public int PersonId { get; set; }
    public virtual Person Person { get; set; }
}

因此,使用ASP.NET MVC 3,如何在一个表单中执行人员编辑视图以填充地址中的所有人员属性？

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>Person</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Adresses.FirstOrDefault().Street)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Adresses.FirstOrDefault().Street)
            @Html.ValidationMessageFor(model => model.Adresses.FirstOrDefault().Street)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

这可以很好地显示来自数据库的Street输入,但是当我进行提交时,Street不会改变.

[HttpPost]
public ActionResult Edit(int id,FormCollection formCollection)
{
    Person person = unityOfWork.PersonRepository.GetById(id);

    UpdateModel<Person>(person);

    if (ModelState.IsValid)
    {
        unityOfWork.PersonRepository.Update(person);
        unityOfWork.SaveChanges();
        return RedirectToAction("Index");
    }

    return View(person);
}
