c# - MVC4中基于下拉选择的FluentValidation Rule依赖验证

Question

我需要根据下拉选择验证两个文本框。它是依赖性验证。为此，我正在使用 FluentValidation。关键在这里，下拉列表的值是语言规范。 (俄罗斯、西类牙语)。

RuleFor(x => x.HasMaterialPublishedElseWhereText).NotEmpty().WithMessage(i18n_Models_Abstract.RequiredField);
RuleFor(x => x.DtPublishedTimeText).NotEmpty().When(x => x.HasMaterialPublishedElseWhereText == i18n_Models_Abstract.AbstractYes).WithMessage(i18n_Models_Abstract.RequiredField);
RuleFor(x => x.PublishedPlaceText).NotEmpty().When(x => x.HasMaterialPublishedElseWhereText == i18n_Models_Abstract.AbstractYes).WithMessage(i18n_Models_Abstract.RequiredField);

 <div class="row" style="padding-bottom: 10px">
  <div class="col-md-10">
   <div class="col-md-4">
      @Html.HiddenFor(model => model.HasMaterialPublishedElseWhereOptions)
      @{
           options = Model.HasMaterialPublishedElseWhereOptions;
           optionsList = options.Split(',').ToList();
           optionSelect = optionsList.Select(option => new SelectListItem() { Text = option, Value = option }).ToList();
        }
        @Html.DropDownListFor(model => model.HasMaterialPublishedElseWhereText, optionSelect, i18n_Models_Abstract.SelectOption +"...", new { @class = "input-validation-error form-control" })
        @Html.ValidationMessageFor(model => model.HasMaterialPublishedElseWhereText)
    </div>
   </div>

HTML

  <div class="col-md-4">
       <input id="HasMaterialPublishedElseWhereOptions" name="HasMaterialPublishedElseWhereOptions" type="hidden" value="да/yes,нет/no">
       <select class="input-validation-error form-control" data-val="true" data-val-required="обязательное поле" id="HasMaterialPublishedElseWhereText" name="HasMaterialPublishedElseWhereText">
    <option value="">Выбрать опции...</option>
    <option selected="selected" value="да/yes">да/yes</option>
    <option value="нет/no">нет/no</option>
</select>
    <span class="field-validation-valid" data-valmsg-for="HasMaterialPublishedElseWhereText" data-valmsg-replace="true"></span>
  </div>
  <div class="col-md-4">
     <input class="form-control" id="DtPublishedTimeText" maxlength="40" name="DtPublishedTimeText" placeholder="Если Да, укажите дату публикации/If yes, Date" type="text" value="">
     <span class="field-validation-valid" data-valmsg-for="DtPublishedTimeText" data-valmsg-replace="true"></span>
   </div>
<div class="col-md-4">
    <input class="form-control" id="PublishedPlaceText" maxlength="40" name="PublishedPlaceText" placeholder="" type="text" value="">
    <span class="field-validation-valid" data-valmsg-for="PublishedPlaceText" data-valmsg-replace="true"></span>
  </div>

所有其他验证都有效，除了这个依赖项不起作用？有什么不对吗？

Answer 1

依赖验证不会生成适当的 html 属性，因为依赖值(true 或 false)只有在用户输入后才能知道。

既不是 jquery.validate 框架(基于客户端验证)，也不是 MVC 模型元数据基础设施(用于可以转换为客户端的简单规则)边规则)，不支持多个属性集，因此，MVC 基础结构决定根本不生成任何属性。

同样的逻辑适用于规则集定制:在指定规则集下定义的规则不参与验证属性生成。
