xVal - 僅爲ID字段生成規則

Question

我正在關注此post。

服務器端驗證按預期工作。但客戶端驗證器只能在ID字段中生成。

我的LINQ2SQL實體類有兩個屬性ID &類別名稱及以下是我的元數據類

[MetadataType(typeof(BookCategoryMetadata))] 
public partial class BookCategory{} 

public class BookCategoryMetadata 
{ 
    [Required] 
    [StringLength(50)] 
    public string CategoryName { get; set; } 
} 

方法添加一個類別

/// <summary> 
/// Adds the category. 
/// </summary> 
/// <param name="category">The category.</param> 
public void AddCategory(BookCategory category) 
{ 
    var errors = DataAnotationsValidationHelper.GetErrors(category); 
    if (errors.Any()) { 
     throw new RulesException(errors); 
    } 

    _db.BookCategories.InsertOnSubmit(category); 
    _db.SubmitChanges(); 
} 

控制器創建行動

[AcceptVerbs(HttpVerbs.Post)] 
public ActionResult Create([Bind(Exclude = "ID")]BookCategory category) 
{ 
    try { 
     _repository.AddCategory(category); 
    } catch (RulesException ex) { 
     ex.AddModelStateErrors(ModelState, ""); 
    } 

    return ModelState.IsValid ? RedirectToAction("Index") : (ActionResult)View(); 
} 

和視圖

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 

<h2>Create</h2> 

<%= Html.ValidationSummary("Create was unsuccessful. Please correct the errors and try again.") %> 

<% using (Html.BeginForm()) {%> 

    <fieldset> 
     <legend>Fields</legend> 
     <p> 
      <label for="CategoryName">CategoryName:</label> 
      <%= Html.TextBox("CategoryName") %> 
      <%= Html.ValidationMessage("CategoryName", "*") %> 
     </p> 
     <p> 
      <input type="submit" value="Create" /> 
     </p> 
    </fieldset> 

<% } %> 

<div> 
    <%=Html.ActionLink("Back to List", "Index") %> 
</div> 
<%= Html.ClientSideValidation<BookCategory>() %> 

現在XVAL僅用於ID字段生成驗證規則。

<script type="text/javascript">xVal.AttachValidator(null, {"Fields":[{"FieldName":"ID","FieldRules":[{"RuleName":"DataType","RuleParameters":{"Type":"Integer"}}]}]})</script> 

對CategoryName的服務器端驗證非常完美。爲什麼xVal沒有爲CategoryName生成驗證規則？我究竟做錯了什麼？

假設xVal 0.8有夥伴類正在工作。如果這

如果不解決您的問題，儘量拉低最新的代碼XVAL和修改xVal.RuleProviders.PropertyAttributeRuleProviderBase::GetRulesFromTypeCore是

protected override RuleSet GetRulesFromTypeCore(Type type) 
{ 
    var typeDescriptor = metadataProviderFactory(type).GetTypeDescriptor(type); 
    var rules = (from prop in typeDescriptor.GetProperties().Cast<PropertyDescriptor>() 
         from rule in GetRulesFromProperty(prop) 
         select new KeyValuePair<string, Rule>(prop.Name, rule)); 

    var metadataAttrib = type.GetCustomAttributes(typeof(MetadataTypeAttribute), true).OfType<MetadataTypeAttribute>().FirstOrDefault(); 
    var buddyClassOrModelClass = metadataAttrib != null ? metadataAttrib.MetadataClassType : type; 
    var buddyClassProperties = TypeDescriptor.GetProperties(buddyClassOrModelClass).Cast<PropertyDescriptor>(); 
    var modelClassProperties = TypeDescriptor.GetProperties(type).Cast<PropertyDescriptor>(); 

    var buddyRules = from buddyProp in buddyClassProperties 
           join modelProp in modelClassProperties on buddyProp.Name equals modelProp.Name 
           from rule in GetRulesFromProperty(buddyProp) 
           select new KeyValuePair<string, Rule>(buddyProp.Name, rule); 

    rules = rules.Union(buddyRules); 
    return new RuleSet(rules.ToLookup(x => x.Key, x => x.Value)); 
}
