流畅的验证.错误:不显眼的客户端验证规则中的验证类型名称必须是唯一的 [英] Fluent Validations. Error: Validation type names in unobtrusive client validation rules must be unique

问题描述

我得到了错误:

不显眼的验证类型名称客户端验证规则必须是独特的.以下验证类型被看到不止一次:需要.这看到以下验证类型不止一次:必填

Validation type names in unobtrusive client validation rules must be unique. The following validation type was seen more than once: required. The following validation type was seen more than once: required

我使用了服务器验证.一切正常.但现在我要使用客户端验证，但我遇到了这个问题.

I used server validation. And all worked fine. But now I`m stating to use client-side validation and I got this problem.

这是我的验证类代码:

public class TestViewDataValidation : BaseTestCreateViewDataValidation<BaseTestCreateViewData>
    {

public TestViewDataValidation ()
        {
            this.RuleFor(x => x.Login).NotNull();
            this.RuleFor(x => x.Login).NotEmpty();
            this.RuleFor(x => x.Login).EmailAddress();          
        }
}

但是如果我留下一个验证器 - 一切正常.我应该怎么做才能对字段进行更多的验证.

But if I leave one validator - all works fine. What should I do to have more that one validation for field.

推荐答案

FluentValidation.NET 之所以称为 Fluent 是因为它提供了一个 流式接口，用于链接方法:

FluentValidation.NET is called Fluent because it provides a fluent interface for chaining methods:

public TestViewDataValidation()
{
    RuleFor(x => x.Login)
        .NotNull()
        .NotEmpty()
        .EmailAddress();
}

备注:在这种情况下，NotNull 和 NotEmpty 规则的使用对我来说似乎是多余的.NotEmpty 应该足够了.

Remark: the usage of NotNull and NotEmpty rules seem reduntant to me in this case. NotEmpty should be enough.
