在我的 ASP.NET MVC 4 项目中,我的 View 模型之一有验证器,其中包含规则集的规则定义。当所有客户端验证通过时,在 Post 操作中使用的 Edit
规则集。 Url
和 Email
规则集用于 Edit
规则集(您可以在下面看到)以及仅验证电子邮件和 URL 的特殊 ajax 操作中使用的规则相应地。
我的问题是 View 不知道它应该使用 Edit
规则集来生成客户端 html 属性,并使用 default
规则集,该规则集为空。 如何告诉 View 使用Edit
规则集来生成输入属性?
型号:
public class ShopInfoViewModel
{
public long ShopId { get; set; }
public string Name { get; set; }
public string Url { get; set; }
public string Description { get; set; }
public string Email { get; set; }
}
验证器:
public class ShopInfoViewModelValidator : AbstractValidator<ShopInfoViewModel>
{
public ShopInfoViewModelValidator()
{
var shopManagementService = ServiceLocator.Instance.GetService<IShopService>();
RuleSet("Edit", () =>
{
RuleFor(x => x.Name)
.NotEmpty().WithMessage("Enter name.")
.Length(0, 255).WithMessage("Name length should not exceed 255 chars.");
RuleFor(x => x.Description)
.NotEmpty().WithMessage("Enter name.")
.Length(0, 10000).WithMessage("Name length should not exceed 10000 chars.");
ApplyUrlRule(shopManagementService);
ApplyEmailRule(shopManagementService);
});
RuleSet("Url", () => ApplyUrlRule(shopManagementService));
RuleSet("Email", () => ApplyEmailRule(shopManagementService));
}
private void ApplyUrlRule(IShopService shopService)
{
RuleFor(x => x.Url)
.NotEmpty().WithMessage("Enter url.")
.Length(4, 30).WithMessage("Length between 4 and 30 chars.")
.Matches(@"[a-z\-\d]").WithMessage("Incorrect format.")
.Must((model, url) => shopService.Available(url, model.ShopId)).WithMessage("Shop with this url already exists.");
}
private void ApplyEmailRule(IShopService shopService)
{
// similar to url rule: not empty, length, regex and must check for unique
}
}
验证操作示例:
public ActionResult ValidateShopInfoUrl([CustomizeValidator(RuleSet = "Url")]
ShopInfoViewModel infoViewModel)
{
return Validation(ModelState);
}
ShopInfoViewModel
的获取和发布操作:
[HttpGet]
public ActionResult ShopInfo()
{
var viewModel = OwnedShop.ToViewModel();
return PartialView("_ShopInfo", viewModel);
}
[HttpPost]
public ActionResult ShopInfo(CustomizeValidator(RuleSet = "Edit")]ShopInfoViewModel infoViewModel)
{
var success = false;
if (ModelState.IsValid)
{
// save logic goes here
}
}
View 包含下一个代码:
@{
Html.EnableClientValidation(true);
Html.EnableUnobtrusiveJavaScript(true);
}
<form class="master-form" action="@Url.RouteUrl(ManagementRoutes.ShopInfo)" method="POST" id="masterforminfo">
@Html.TextBoxFor(x => x.Name)
@Html.TextBoxFor(x => x.Url, new { validationUrl = Url.RouteUrl(ManagementRoutes.ValidateShopInfoUrl) })
@Html.TextAreaFor(x => x.Description)
@Html.TextBoxFor(x => x.Email, new { validationUrl = Url.RouteUrl(ManagementRoutes.ValidateShopInfoEmail) })
<input type="submit" name="asdfasfd" value="Сохранить" style="display: none">
</form>
结果 html 输入(没有任何客户端验证属性):
<input name="Name" type="text" value="Super Shop"/>
最佳答案
在深入研究 FluentValidation 源代码后,我找到了解决方案。要告诉 View 您要使用特定的规则集,请使用 RuleSetForClientSideMessagesAttribute
装饰返回 View 的操作:
[HttpGet]
[RuleSetForClientSideMessages("Edit")]
public ActionResult ShopInfo()
{
var viewModel = OwnedShop.ToViewModel();
return PartialView("_ShopInfo", viewModel);
}
如果您需要指定多个规则集 - 使用另一个构造函数重载并用逗号分隔规则集:
[RuleSetForClientSideMessages("Edit", "Email", "Url")]
public ActionResult ShopInfo()
{
var viewModel = OwnedShop.ToViewModel();
return PartialView("_ShopInfo", viewModel);
}
如果您需要决定在操作中直接使用哪个规则集 - 您可以通过将数组放入 HttpContext 中来破解 FluentValidation(RuleSetForClientSideMessagesAttribute
当前未设计为被覆盖):
public ActionResult ShopInfo(validateOnlyEmail)
{
var emailRuleSet = new[]{"Email"};
var allRuleSet = new[]{"Edit", "Url", "Email"};
var actualRuleSet = validateOnlyEmail ? emailRuleSet : allRuleSet;
HttpContext.Items["_FV_ClientSideRuleSet"] = actualRuleSet;
return PartialView("_ShopInfo", viewModel);
}
不幸的是,官方文档中没有关于此属性的信息。
更新
在最新版本中,我们为动态规则集设置提供了特殊的扩展方法,您应该在操作方法或OnActionExecuting
/OnActionExecuted
内部使用它/OnResultExecuting
重写 Controller 方法:
ControllerContext.SetRulesetForClientsideMessages("Edit", "Email");
或者在自定义ActionFilter
/ResultFilter
内:
public class MyFilter: ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext context)
{
((Controller)context.Controller).ControllerContext.SetRulesetForClientsideMessages("Edit", "Email");
//same syntax for OnActionExecuted/OnResultExecuting
}
}
