不顯示不顯示驗證的ASP.NET MVC數據val屬性

Question

我掙扎了好幾個小時，試圖理解爲什麼我在表單中呈現的輸入元素不再包含data-val屬性。 環境是MVC 5和.NET Framework 4.5（I從MVC 4升級希望解決問題！）

所呈現的字段中的一個的一個例子：

<input id="UserName" class="text-box single-line" type="text" value="" name="UserName"> 
</input> 
<span class="field-validation-valid" data-valmsg-replace="true" data-valmsg-for="UserName"></span> 

我的模型：

public class AccountRegistrationValidation 
    { 
    [Key] 
    public int ID { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [System.Web.Mvc.Remote("UsernameInUse", "Account", HttpMethod = "POST", 
      ErrorMessageResourceType = typeof(ValidationStrings), ErrorMessageResourceName = "UsernameExists")] 
    public string UserName { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [StringLength(20, ErrorMessageResourceName = "PasswordMinLength", ErrorMessageResourceType = typeof(ValidationStrings), MinimumLength = 6)] 
    [DataType(DataType.Password)] 
    public string Password { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [DataType(DataType.Password)] 
    [System.Web.Mvc.Compare("Password", ErrorMessageResourceName = "PasswordsMustMatch", ErrorMessageResourceType = typeof(ValidationStrings))] 
    public string ConfirmPassword { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [DataType(DataType.EmailAddress)] 
    [System.Web.Mvc.Remote("EmailInUse", "Account", HttpMethod = "POST", ErrorMessage = "Email address already exists. Please enter a different address.")] 
    public string Email { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [DataType(DataType.Text)] 
    public string FirstName { get; set; } 

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(ValidationStrings))] 
    [DataType(DataType.Text)] 
    public string LastName { get; set; } 
    } 

觀形態：

@model Test.Models.AccountRegistrationValidation 
@using CaptchaMvc.HtmlHelpers 
@{ 
    ViewBag.Title = ViewRes.RegisterStrings.RegisterTitle; 

} 



<div class="container"> 
<div class="row-fluid"> 
    <div class="span12"> 
     <div class="page-header"> 
      <h1>@ViewBag.Title <br /><small>@ViewRes.RegisterStrings.RegisterSubTitle</small></h1> 

     </div> 
    </div> 
</div> 
<div class="row-fluid"> 
    <div class="span7"> 


@using (Html.BeginForm("Register", "Account", FormMethod.Post, new { @class = "form-horizontal" }))

</div> 

</div> 


@section Scripts 
{ 

    @Scripts.Render("~/bundles/jqueryval") 

} 

我查看包括所有必需的js文件（jquery.validate和jquery.validate.unobtrusive）

任何想法？！？

Answer 1

您需要做的是在您的控制器中插入以下代碼。它所做的是驗證模型中的所有要求是否都滿足。

public ActionResult Register(Models.MyModel Model) 
    { 
     if (ModelState.IsValid) 
     { 
     } 
    }

我有完全一樣的問題 - ValidationMessageFor（）跨度均呈現正常，但數據-VAL *上的輸入字段屬性是無處可看。在我們上週更新了一系列NuGet軟件包之前，所有的工作都很完美。

我們使用帶有FluentValidation的NInject來爲我們的應用程序的特定區域提供一些自定義驗證器。隱藏在這些自定義驗證綁定是以下行： -

kernel.Unbind<ModelValidatorProvider>(); 

我們評論這條線的，並且數據-VAL *屬性是回來了，一切都太棒了一次。我們最近升級了所有的Nu​​Get包（主要是從MVC 5.0.0.0升級到MVC 5.2.0.0和WebApi 2.2）後才發現這很明顯。一路走來，許多其他軟件包升級，包括FluentValidation和NInject。

這行代碼沒有改變，所以有可能NInject的行爲在版本3.0和3.2之間改變了，因爲它在更新之前一切正常。

我的建議 - 檢查你的IoC綁定，因爲它可能是你正在攔截默認模型驗證行爲的地方。
