ASP验证 - 萨默里在模型模式下未显示错误

我已经注意到，当asp-validation-summary =“ modelonly”时，未显示错误。当我将值更改为asp-validation-summary =“ all”时，它可以正常工作。

也许是因为我正在使用验证attribute？这是代码样本：

@page "/pages/test"
@model TestPageModel
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@addTagHelper *, WebApp
@using Microsoft.AspNetCore.Mvc.ModelBinding
@using Microsoft.AspNetCore.Mvc.RazorPages
@using System.ComponentModel.DataAnnotations

<!DOCTYPE html>
<html>
<head>
    <link href="~/lib/twitter-bootstrap/css/bootstrap.min.css" rel="stylesheet" />
</head>
<body>
    <div class="m-2">
        <h5 class="bg-primary text-white text-center p-2">TEST</h5>
        <form asp-page="TestPage" method="post">
            <div asp-validation-summary="ModelOnly" class="text-danger"></div>
            <div class="form-group">
                <label>Name</label>
                <div><span asp-validation-for="TestModel.Value" class="text-danger"></span></div>
                <input class="form-control" asp-for="TestModel.Value" />
            </div>
            <button type="submit" class="btn btn-primary">Submit</button>
        </form>
    </div>
</body>
</html>

@functions{
    public class TestPageModel : PageModel
    {
        [BindProperty]
        public TestModel TestModel { get; set; } = new TestModel();

        public Task OnGetAsync()
        {

            TestModel = new TestModel() { Value = "Some value" };
            return Task.CompletedTask;
        }

        public IActionResult OnPost() => Page();
    }

    public class TestValidationAttribute : ValidationAttribute
    {
        protected override ValidationResult IsValid(object? value, ValidationContext validationContext)
        {
            return new ValidationResult("Something is wrong");
        }
    }

    [TestValidation]
    public class TestModel
    {
        public string Value { get; set; } = string.Empty;
    }
}

您能帮我找到缺少的东西吗？

原文

I have noticed that errors are not shown when asp-validation-summary="ModelOnly". When I change value to asp-validation-summary="All" it works fine.

Maybe it is because I am using ValidationAttribute?
Here is code sample:

@page "/pages/test"
@model TestPageModel
@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
@addTagHelper *, WebApp
@using Microsoft.AspNetCore.Mvc.ModelBinding
@using Microsoft.AspNetCore.Mvc.RazorPages
@using System.ComponentModel.DataAnnotations

<!DOCTYPE html>
<html>
<head>
    <link href="~/lib/twitter-bootstrap/css/bootstrap.min.css" rel="stylesheet" />
</head>
<body>
    <div class="m-2">
        <h5 class="bg-primary text-white text-center p-2">TEST</h5>
        <form asp-page="TestPage" method="post">
            <div asp-validation-summary="ModelOnly" class="text-danger"></div>
            <div class="form-group">
                <label>Name</label>
                <div><span asp-validation-for="TestModel.Value" class="text-danger"></span></div>
                <input class="form-control" asp-for="TestModel.Value" />
            </div>
            <button type="submit" class="btn btn-primary">Submit</button>
        </form>
    </div>
</body>
</html>

@functions{
    public class TestPageModel : PageModel
    {
        [BindProperty]
        public TestModel TestModel { get; set; } = new TestModel();

        public Task OnGetAsync()
        {

            TestModel = new TestModel() { Value = "Some value" };
            return Task.CompletedTask;
        }

        public IActionResult OnPost() => Page();
    }

    public class TestValidationAttribute : ValidationAttribute
    {
        protected override ValidationResult IsValid(object? value, ValidationContext validationContext)
        {
            return new ValidationResult("Something is wrong");
        }
    }

    [TestValidation]
    public class TestModel
    {
        public string Value { get; set; } = string.Empty;
    }
}

Could you please help me find what is missing?
