asp.net-mvc - 如何使用asp.net mvc EditorTemplate

Question

我读到 EditorTemplates 是自动加载的，但是从 asp.net mvc 2 和现在的 3 with razor，我仍然无法让它工作。

我的模型看起来像这样:

public class RoleViewModel
{
    public int RoleId { get; set; }
    public bool InRole { get; set; }
    public string RoleName { get; set; }
}

public class UserViewModel
{
    public User User { get; set; }
    public IEnumerable<RoleViewModel> Roles { get; set; }
}

我的观点是这样的:

~/Views/Roles/Edit.cshtml

@model Project.Web.ViewModel.UserViewModel
@using (Html.BeginForm()) {
   @Html.EditorFor(model => model.Roles)
   <!-- Other stuff here -->
}

~/Views/Roles/EditorTemplates/RoleViewModel.cshtml

@model Project.Web.ViewModel.RoleViewModel
@foreach (var i in Model)
{
    <div>
    @i.RoleName
    @Html.HiddenFor(model => i.RoleId)
    @Html.CheckBoxFor(model => i.InRole)
    </div>
}

如果我从 EditorTemplate 移动内容到实际页面，然后它就可以工作了，它会显示复选框等。但是在当前的设置中，显示的只是角色数量的计数。

我究竟做错了什么？

~/Views/Roles/EditorTemplates/RoleViewModel.cshtml

@model MvcApplication16.Controllers.RoleViewModel
<div>
    @Model.RoleName
    @Html.HiddenFor(m => m.RoleId)
    @Html.CheckBoxFor(m => m.InRole)
</div>

〜/ View /角色/Edit.cshtml

@model MvcApplication16.Controllers.UserViewModel
@using (Html.BeginForm()) {
   @Html.EditorFor(m => m.Roles)
   <!-- Other stuff here -->
}

楷模

public class UserViewModel {
    public User User { get; set; }
    public IEnumerable<RoleViewModel> Roles { get; set; }
}

public class RoleViewModel {
    public int RoleId { get; set; }
    public bool InRole { get; set; }
    public string RoleName { get; set; }
}

public class User {
    public string Name { get; set; }
}

Controller

public ActionResult Edit() {
    return View(
        new UserViewModel() {
            User = new User() { Name = "Test" },
            Roles = new List<RoleViewModel>() { 
                new RoleViewModel() { 
                    RoleId = 1, 
                    InRole = true, 
                    RoleName = "Test Role" }}
        });
}

上面的代码工作得很好。将它与您的进行比较，看看您是否发现任何问题:)
