我正在尝试通过数据注释添加自定义数据验证。我现在只关心服务器端验证。我在这里和其他地方看到的所有内容都引用了客户端验证。我已经删除了所有代码,运行了一些测试用例,我可以在常规视图中正常工作但是只要表单处于局部视图中,代码就不再在方法中中断以覆盖IsValid。
在任何一种情况下,我都可以看到自定义属性被初始化。当表单处于常规视图中时,我可以看到在提交表单时执行的覆盖方法,但是在部分视图中,代码永远不会被执行,而是直接进入HttpPost操作。
我花了两天的时间来试图解决这个问题,但我感到很茫然。任何帮助都会非常感激。
注意: 下面的代码在进入HttpPost操作时会返回相同的视图。我有这样的测试用途。我知道我的覆盖永远不会从局部视图调用,因此IsValid始终是真的。

@model eRecruitBoard.ViewModels.HomeIndexViewModel
@{
ViewBag.Title = "eRecruitBoard";
}
@*<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<p>
<input type="submit" value="Log In" />
</p>
</fieldset>

}
<div>
@Html.Action("BlankForm", "TestForm")
</div>
部分视图(这些脚本调用也来自_Layout,但我也在这里进行测试)
@model eRecruitBoard.ViewModels.TestFormViewModel
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcValidation.js")" type="text/javascript"></script>
@using (Html.BeginForm("NewActivity2", "TestForm", FormMethod.Post))
{
<fieldset>
<legend>Test Form</legend>
<br />
@Html.LabelFor(m => m.Date)
@Html.EditorFor(m => m.Date)
@Html.ValidationMessageFor(m => m.Date)
<input id="activityTimelineSubmit" type="submit" value="Submit" />
</fieldset>
}
ViewModel(部分视图)
namespace eRecruitBoard.ViewModels
{
public class TestFormViewModel
{
[Required]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
[NonFutureDate()]
[Display(Name = "Date")]
public DateTime Date { get; set; }
}
}
控制器(部分视图)
namespace eRecruitBoard.Controllers
{
public class TestFormController :BaseController
{
public ActionResult BlankForm()
{
var viewModel = new TestFormViewModel
{
Date = DateTime.Today
};
return PartialView("_TestForm", viewModel);
}
[HttpPost]
public ActionResult NewActivity2(DateTime Date)
{
if (!ModelState.IsValid)
return RedirectToAction("Index", "Home");
else
return RedirectToAction("Index", "Home");
}
}
}
验证码
using System;
using System.ComponentModel.DataAnnotations;
namespace eRecruitBoard.WebLibrary.Validation
{
[AttributeUsageAttribute(AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false, Inherited = true)]
public class NonFutureDateAttribute : ValidationAttribute //public sealed class
{
public NonFutureDateAttribute(): base("Activity can only be saved for today or dates in the past.")
{
}
public override bool IsValid(object value)
{
DateTime dateToCheck = (DateTime)value;
return (dateToCheck <= DateTime.Today);
}
}
}
答案 0 :(得分:2)
如果您RedirectToAction
丢失了所有验证。您必须在POST操作中return PartialView(model)
。这需要将NewActivity2
的参数类型更改为TestFormViewModel
而不是DateTime
。
使用如何显示部分视图(@Html.Partial()
或javascript)的示例更新代码,如果它仍然无效。
