Razor中的MVC数据注释 [英] MVC Data Annotations in Razor

问题描述

我正在尝试在我的MVC项目(Mono/.NET 4.5)中使用数据注释.我已经创建了模型并添加了所有适当的注释.我的视线和控制器已正确连接.但是，验证似乎没有发生.我已经尽力尝试了一切，但都无济于事.因为这是我第一次使用Razor和数据注释，所以我想我缺少一些设置文件，但我终生找不到.这是我的代码:

I'm trying to use Data Annotations in my MVC project (Mono/.NET 4.5). I've created my model and added all the appropriate annotations. I have my view and controller appropriately wired up. However, the validation just doesn't seem to be happening. I've tried everything I can find to no avail. As this is my first time working with Razor and Data Annotations, I imagine there is some setup piece I'm missing but I can't find it for the life of me. Here's my code:

模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace MyWebsite
{
  public class RegisterViewModel : BaseViewModel
  {
    #region properties
    [Required(ErrorMessage = "Required")]
    [StringLength(50)]
    [DisplayName("First Name")]
    public string FirstName { get; set; }
    [Required(ErrorMessage = "Required")]
    [StringLength(100)]
    [DisplayName("Last Name")]
    public string LastName { get; set; }
    [StringLength(50)]
    [DisplayName("Display Name")]
    public string DisplayName { get; set; }
    [Required(ErrorMessage = "Required")]
    [StringLength(255)]
    [DisplayName("Email Address")]
    public string EmailAddress { get; set; }
    #endregion

    #region ctor
    public RegisterViewModel ()
    {

    }
    #endregion

  }
}

控制器

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MyWebsite.Controllers
{
  public class AccountController : Controller
  {
    public ActionResult Register()
    {
        ViewData ["IsComplete"] = false;
        ViewData ["RequiredVouches"] = WebSettings.RequiredVouches;

        return View ();
    }

    [HttpPost]
    public ActionResult Register(FormCollection formData)
    {
        if (ModelState.IsValid) {
            //TODO: Put the data
            ViewData ["IsComplete"] = true;
        }
        return View ();
    }
  }
}

查看

@model SummerIsles.Web.RegisterViewModel
@section Styles {
<link href="~/Content/themes/base/Account.css" rel="stylesheet" type="text/css" />
}
@{
if((bool)@ViewData["IsComplete"]) {
    <h1>Registration Request Complete!</h1>
    <div class="page-message">
        <p>
           Confirmation message goes here
        </p>
    </div>
}
else {
    <h1>Registration</h1>
    <div class="page-message">
        <p>
            Instruction text goes here
        </p>
    </div>
    using (Html.BeginForm()) {
        @Html.ValidationSummary(false)
        <fieldset>
            <legend>Your Information</legend>

            <div class="group column-1">
                @Html.LabelFor(modelItem => @Model.FirstName)
                @Html.EditorFor(modelItem => @Model.FirstName, new { htmlAttributes = new { @class="form-control" } } )
                @Html.ValidationMessageFor(modelItem => @Model.FirstName)

                @Html.LabelFor(modelItem => @Model.DisplayName)
                @Html.EditorFor(modelItem => @Model.DisplayName, new { htmlAttributes = new { @class="form-control" } } )
                @Html.ValidationMessageFor(modelItem => @Model.DisplayName)
            </div>

            <div class="group column-2">
                @Html.LabelFor(modelItem => @Model.LastName)
                @Html.EditorFor(modelItem => @Model.LastName, new { htmlAttributes = new { @class="form-control" } } )
                @Html.ValidationMessageFor(modelItem => @Model.LastName)

                @Html.LabelFor(modelItem => @Model.EmailAddress)
                @Html.EditorFor(modelItem => @Model.EmailAddress, new { htmlAttributes = new { @class="form-control" } } )
                @Html.ValidationMessageFor(modelItem => @Model.EmailAddress)
            </div>

            <div class="button-options">
                <button id="btnSubmit" type="submit" formmethod="post" class="btn btn-danger">Submit</button>
                <a id="btnCancel" href="~/" class="btn">Cancel</a>
            </div>
        </fieldset>
    }
  }
}

此外，我已经将jquery验证脚本添加到布局文件中，并且还在web.confg中启用了客户端验证.

Also, I have added the jquery validation scripts to my layout file and have also enabled client validation in the web.confg.

布局标题

<head>
  <!--some other css and such-->
  <script src="~/Scripts/jquery.validate.min.js"></script>
  <script src="~/Scripts/jquery.validate.unobstrusive.min.js"></script>
</head>

Web.config

<appSettings>
   <!--some other stuff-->
   <add key="ClientValidationEnabled" value="true" />
   <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

基本上，当我单击提交"时，它认为模型是完全有效的(ModelState.IsValid在控制器中返回true)，而验证的东西(我希望在发回到控制器之前会触发)不会出现.即使使用完全空白的表单(尽管具有"Required"数据注释)，我也没有收到任何验证消息.我想念什么?

Basically, when I click submit, it thinks the model is perfectly valid (ModelState.IsValid returns true in the controller) and the validation stuff (which I would expect to fire before the post back to the controller) never seems to fire. I get no validation messages even with a completely blank form (despite having the "Required" data annotation). What am I missing?

推荐答案

@Html.ValidationMessageFor(modelItem => @Model.LastName)

应该是

@Html.ValidationMessageFor(modelItem => modelItem.LastName)

用于 all 您的HtmlHelpers，包括TextBoxFor和LabelFor等.

for all your HtmlHelpers, including TextBoxFor and LabelFor etc.

也

public ActionResult Register(FormCollection formData)

应该是

public ActionResult Register(RegisterViewModel model)

为了使服务器端ModelState.IsValid正常工作.

in order for your server side ModelState.IsValid to work.
