我想验证使用流畅验证的视图模型。当我发布viewmodel对象时，modelstate.isvalid总是返回false。当我检查了发布对象上的值时，用于获取要在下拉菜单中显示的数据的属性也正在验证中。如何解决这个问题。我是否以错误的方式做，请帮助。 我是ASP.net MVC的新手，只是尝试在这个项目中使用流畅的验证和流畅的NHibernate映射。使用流畅验证验证视图模型的问题
更多细节如下：
我有如下域模型对象：
[Validator(typeof(TestRequirementValidator))]
public class TestRequirement
{
public virtual int Id { get; private set; }
public virtual int SampleId { get; set; }
public virtual int TestId { get; set; }
public virtual int StandardId { get; set; }
public virtual string Description { get; set; }
public virtual Sample Sample { get; set; }
public virtual Test Test { get; set; }
public virtual Standard Standard { get; set; }
}
我已经创建如下面的图模型：
[Validator(typeof(TestRequirementViewModelValidator))]
public class TestRequirementViewModel
{
public TestRequirement TestRequirement;
public SelectList Samples;
public SelectList Tests;
public SelectList Standards;
public TestRequirementViewModel()
{
ISession _session = FNHsessionFactory.GetSessionFactory();
this.TestRequirement = new TestRequirement();
this.Samples = new SelectList(from S in _session.Linq<Sample>() select S, "Id", "Name");
this.Tests = new SelectList(from T in _session.Linq<Test>() select T, "Id", "Name");
this.Standards = new SelectList(from St in _session.Linq<Standard>() select St, "Id", "Name");
}
}
模型验证器是如下：
public class TestRequirementValidator : AbstractValidator<TestRequirement>
{
public TestRequirementValidator()
{
RuleFor(x => x.SampleId)
.NotEmpty()
.WithMessage("This field is required")
.DisplayName("Sample Name");
RuleFor(x => x.TestId)
.DisplayName("Test Name");
RuleFor(x => x.StandardId)
.NotEmpty()
.WithMessage("This field is required")
.DisplayName("Standard Name");
RuleFor(x => x.Description)
.NotEmpty()
.WithMessage("This field is required")
.Length(0, 10)
.WithMessage("Length of this field cannot be more than 10 characters");
}
}
视图模型验证程序如下：
public class TestRequirementViewModelValidator:AbstractValidator-TestRequirementViewModel-
{
public TestRequirementViewModelValidator()
{
RuleFor(x => x.TestRequirement)
.SetValidator(new TestRequirementValidator());
}
}
示意图如下：
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<foo.Models.ViewModels.TestRequirementViewModel>" MasterPageFile="~/Views/shared/site.master" %>
<asp:Content ContentPlaceHolderID="MainContent" ID="MainContentContent" runat="server">
<h3><%= Html.Encode(ViewData["Message"]) %></h3>
<% using (Html.BeginForm()) {%>
<%= Html.ValidationSummary(true) %>
<fieldset>
<legend>Create Test Requirement</legend>
<div class="editor-label">
<%= Html.LabelFor(model => model.TestRequirement.SampleId) %>
</div>
<div class="editor-field">
<%= Html.DropDownListFor(model => model.TestRequirement.SampleId, new SelectList(Model.Samples.Items, Model.Samples.DataValueField, Model.Samples.DataTextField), "Select Sample") %>
<%= Html.ValidationMessageFor(model => model.TestRequirement.SampleId) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.TestRequirement.TestId) %>
</div>
<div class="editor-field">
<%= Html.DropDownListFor(model => model.TestRequirement.TestId, new SelectList(Model.Tests.Items, Model.Tests.DataValueField, Model.Tests.DataTextField), "Select Test") %>
<%= Html.ValidationMessageFor(model => model.TestRequirement.TestId) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.TestRequirement.StandardId) %>
</div>
<div class="editor-field">
<%= Html.DropDownListFor(model => model.TestRequirement.StandardId, new SelectList(Model.Standards.Items, Model.Standards.DataValueField, Model.Standards.DataTextField), "Select Standard") %>
<%= Html.ValidationMessageFor(model => model.TestRequirement.StandardId) %>
</div>
<div class="editor-label">
<%= Html.LabelFor(model => model.TestRequirement.Description) %>
</div>
<div class="editor-field">
<%= Html.TextBoxFor(model => model.TestRequirement.Description) %>
<%= Html.ValidationMessageFor(model => model.TestRequirement.Description) %>
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
<% } %>
<%= Html.ClientSideValidation<TestRequirement>("TestRequirement") %>
</asp:Content>
控制器是如下：
public ActionResult TestRequirement()
{
TestRequirementViewModel NewTestRequirement = new TestRequirementViewModel();
return View(NewTestRequirement);
}
[HttpPost]
public ActionResult TestRequirement(TestRequirementViewModel NewTestRequirement)
{
if(ModelState.IsValid)
{
ISession _session = FNHsessionFactory.GetSessionFactory();
_session.SaveOrUpdate(NewTestRequirement.TestRequirement);
ViewData["Message"] = "New Test Requirement has been created successfully";
return View();
}
return View(NewTestRequirement);
}
