带有ASP.NET MVC2的自定义CMS，存在验证问题

如何完全控制像[RequiredErrorMessage=Title is required]这样的数据注释的处理方式

目前，我的系统忽略所需的注释，因此在编辑它时接受空值

奇怪的是，这在数据库中没有改变，因为数据库中的数据/字段是完整的。所以我猜LINQ在本地存储了一些恼人的东西

你需要更多的细节吗？它基本上只是MVC2中简单的GET/POST操作方法

编辑：

模型如下所示：

public class HomeContent {
    [Required(ErrorMessage = "* Id is required")]
    public int Id { get; set; }

    [Required(ErrorMessage = "* Title is required")]
    [StringLength(50, ErrorMessage = "* Title is too long")]
    public string Title { get; set; }

    [Required(ErrorMessage = "* Content is required")]
    [StringLength(8000, ErrorMessage = "* Content is too long")]
    //8000 = varchar(MAX)
    public string Content { get; set; }

    [Required(ErrorMessage = "* You need to specify a language")]
    public int Language { get; set; }
}

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult HomeControl(HomeContent homeContent) {
        if (!DatabaseService.Instance.ModifyHomeContent(homeContent)) {
            ViewData["Error"] = "An error occured during saving data to the page.";
        } else {
            ViewData["Error"] = "Changes has been saved!";
        }

        return View();
    }

控制器操作如下所示：

public class HomeContent {
    [Required(ErrorMessage = "* Id is required")]
    public int Id { get; set; }

    [Required(ErrorMessage = "* Title is required")]
    [StringLength(50, ErrorMessage = "* Title is too long")]
    public string Title { get; set; }

    [Required(ErrorMessage = "* Content is required")]
    [StringLength(8000, ErrorMessage = "* Content is too long")]
    //8000 = varchar(MAX)
    public string Content { get; set; }

    [Required(ErrorMessage = "* You need to specify a language")]
    public int Language { get; set; }
}

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult HomeControl(HomeContent homeContent) {
        if (!DatabaseService.Instance.ModifyHomeContent(homeContent)) {
            ViewData["Error"] = "An error occured during saving data to the page.";
        } else {
            ViewData["Error"] = "Changes has been saved!";
        }

        return View();
    }

我发现围绕服务类方法调用包装ifModelState.IsValid{…}，它将完全根据数据注释进行验证。

您的问题不清楚。你的模特看起来怎么样？在什么属性上应用这些必需的属性？我编辑了我的问题。我可能已经自己回答了，但我不确定这是否正确。是的，你应该用ModelState.isValid check包装你的服务类
