FluentValidation - 验证包含Object列表的View Model

Question

我正在尝试包含复杂视图模型的项目的FluentValidation,我在这里阅读文档,但我没有看到如何设置规则来验证在我的视图模型中声明的对象列表.在下面的示例中,视图模型中的列表包含一个或多个Guitar对象.谢谢

查看模型

 [FluentValidation.Attributes.Validator(typeof(CustomerViewModelValidator))]
    public class CustomerViewModel
    {
        [Display(Name = "First Name")]
        public string FirstName { get; set; }

        [Display(Name = "Last Name")]
        public string LastName { get; set; }

        [Display(Name = "Phone")]
        public string Phone { get; set; }

        [Display(Name = "Email")]
        public string EmailAddress { get; set; }

        public List<Guitar> Guitars { get; set; } 
    }

View Model中使用的吉他类

public class Guitar
{
    public string Make { get; set; }
    public string Model { get; set; }
    public int? ProductionYear { get; set; }
}

查看模型验证器类

 public class CustomerViewModelValidator : AbstractValidator<CustomerViewModel>
    {


        public CustomerViewModelValidator()
        {
            RuleFor(x => x.FirstName).NotNull();
            RuleFor(x => x.LastName).NotNull();
            RuleFor(x => x.Phone).NotNull();
            RuleFor(x => x.EmailAddress).NotNull();
           //Expects an indexed list of Guitars here????


        }
    }

Answer 1

您可以将其添加到CustomerViewModelValidator

RuleFor(x => x.Guitars).SetCollectionValidator(new GuitarValidator());

所以你的CustomerViewModelValidator看起来像这样:

public class CustomerViewModelValidator : AbstractValidator<CustomerViewModel>
{
    public CustomerViewModelValidator()
    {
        RuleFor(x => x.FirstName).NotNull();
        RuleFor(x => x.LastName).NotNull();
        RuleFor(x => x.Phone).NotNull();
        RuleFor(x => x.EmailAddress).NotNull();
        RuleFor(x => x.Guitars).SetCollectionValidator(new GuitarValidator());
    }
}

添加GuitarValidator看起来像:

public class GuitarValidator : AbstractValidator<Guitar>
{
    public GuitarValidator()
    {
        // All your other validation rules for Guitar. eg.
        RuleFor(x => x.Make).NotNull();
    }
 }

Answer 2

不推荐使用此代码: RuleFor(x => x.Guitars).SetCollectionValidator(new GuitarValidator());

这是新的:

RuleForEach(x => x.Guitars).SetValidator(new GuitarValidator());
