流利的验证不工作的长度 [英] Fluent Validation not working on length

问题描述

我想获得流利的验证在我的客户端验证正常工作。我使用ASP.NET MVC 3。

我有需要的标题和它必须是1至100个字符之间。因此，虽然我的称号我打字显示一条错误消息，是不是在自己的规则。这里是我的规则集：

  RuleFor（X =＆GT; x.Title）
   。不是空的（）
   .WithMessage（标题是必需的）
   。长度（1，100）
   .WithMessage（标题必须小于或等于100个字符）;
 

下面是显示错误消息：

 请输入小于或等于100的值
 

我不知道我做错了。这是我的Global.asax：

  // FluentValidation
DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = FALSE;ModelValidatorProviders.Providers.Clear（）;
ModelValidatorProviders.Providers.Add（
   新FluentValidationModelValidatorProvider（新AttributedValidatorFactory（）））;ModelMetadataProviders.Current =新FluentValidationModelMetadataProvider（
   新AttributedValidatorFactory（））;
 

解决方案

对于我来说工作正常。具体操作步骤如下：

1. 使用默认创建一个新的ASP.NET MVC 3 RTM项目的Visual Studio模板


2. 下载最新的 FluentValidation.NET


3. 引用 FluentValidation.dll 和 FluentValidation.Mvc.dll 组件（小心里面有两个文件夹.ZIP：MVC2和MVC3所以一定要挑选合适的装配）

添加一个模型：

  [验证（typeof运算（MyViewModelValidator））]
公共类MyViewModel
{
    公共字符串名称{搞定;组; }
}
 

和相应的验证：

 公共类MyViewModelValidator：AbstractValidator＆LT; MyViewModel＆GT;
{
    公共MyViewModelValidator（）
    {
        RuleFor（X =＆GT; x.Title）
           。不是空的（）
           .WithMessage（标题是必需的）
           。长度（1，5）
           .WithMessage（标题必须小于或等于5个字符）;
    }
}
 

添加到的Application_Start ：

  DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = FALSE;ModelValidatorProviders.Providers.Clear（）;
ModelValidatorProviders.Providers.Add（
    新FluentValidationModelValidatorProvider（新AttributedValidatorFactory（）））;ModelMetadataProviders.Current =新FluentValidationModelMetadataProvider（
    新AttributedValidatorFactory（））;
 

添加控制器：

 公共类HomeController的：控制器
{
    公众的ActionResult指数（）
    {
        返回查看（新MyViewModel（））;
    }    [HttpPost]
    公众的ActionResult指数（MyViewModel模型）
    {
        返回查看（模型）;
    }
}
 

和相应的视图：

  @model SomeApp.Models.MyViewModel
@ {
    ViewBag.Title =主页;
}
＆LT;脚本的src =@ Url.Content（〜/脚本/ jquery.validate.js）TYPE =文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
＆LT;脚本的src =@ Url.Content（〜/脚本/ jquery.validate.unobtrusive.js）TYPE =文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
@using（Html.BeginForm（））
{
    @ Html.TextBoxFor（X =＆GT; x.Title）
    @ Html.ValidationMessageFor（X =＆GT; x.Title）
    ＆LT;输入类型=提交VALUE =OK/＆GT;
}
 

现在尝试提交表单留下标题输入空=>在客户端验证踢和的是必需的标题消息的显示。现在开始键入一些文字=>错误信息消失。一旦你输入在输入超过5个字符框的标题必须小于或等于5个字符的出现验证消息。所以，一切似乎都如预期工作。

I am trying to get Fluent Validation to work correctly on my client side validation. I am using ASP.NET MVC 3.

I have a title that is required and it must be between 1 and 100 characters long. So while I am typing in the title an error message displays that is not in my ruleset. Here is my rule set:

RuleFor(x => x.Title)
   .NotEmpty()
   .WithMessage("Title is required")
   .Length(1, 100)
   .WithMessage("Title must be less than or equal to 100 characters");

Here is the error message that is displayed:

Please enter a value less than or equal to 100

I'm not sure what I am doing wrong. Here is my global.asax:

// FluentValidation
DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

ModelValidatorProviders.Providers.Clear();
ModelValidatorProviders.Providers.Add(
   new FluentValidationModelValidatorProvider(new AttributedValidatorFactory()));

ModelMetadataProviders.Current = new FluentValidationModelMetadataProvider(
   new AttributedValidatorFactory());

解决方案

Works fine for me. Here are the steps:

1. Create a new ASP.NET MVC 3 RTM project using the default Visual Studio Template
2. Download the latest FluentValidation.NET
3. Reference the FluentValidation.dll and FluentValidation.Mvc.dll assemblies (be careful there are two folders inside the .zip: MVC2 and MVC3 so make sure to pick the proper assembly)

Add a model:

[Validator(typeof(MyViewModelValidator))]
public class MyViewModel
{
    public string Title { get; set; }
}

and a corresponding validator:

public class MyViewModelValidator : AbstractValidator<MyViewModel>
{
    public MyViewModelValidator()
    {
        RuleFor(x => x.Title)
           .NotEmpty()
           .WithMessage("Title is required")
           .Length(1, 5)
           .WithMessage("Title must be less than or equal to 5 characters");
    }
}

Add to Application_Start:

DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false;

ModelValidatorProviders.Providers.Clear();
ModelValidatorProviders.Providers.Add(
    new FluentValidationModelValidatorProvider(new AttributedValidatorFactory()));

ModelMetadataProviders.Current = new FluentValidationModelMetadataProvider(
    new AttributedValidatorFactory());

Add a controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

and the corresponding view:

@model SomeApp.Models.MyViewModel
@{
    ViewBag.Title = "Home Page";
}
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
@using (Html.BeginForm())
{
    @Html.TextBoxFor(x => x.Title)
    @Html.ValidationMessageFor(x => x.Title)
    <input type="submit" value="OK" />
}

Now try to submit the form leaving the Title input empty => client side validation kicks in and the Title is required message is shown. Now start typing some text => the error message disappears. Once you type more than 5 characters in the input box the Title must be less than or equal to 5 characters validation message appears. So everything seems to work as expected.
