我有以下视图,它无法验证标题和新闻内容。标题验证有效,但新闻内容无效。我怎样才能修好它

@model Foo.NewsViewModel
@{
    ViewBag.Title = "Create";
}



@using (Html.BeginForm("Create", "News", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <div>
        <fieldset>

问题:标题验证有效,但新闻内容无效

验证无效,因为使用Html.TextAreaFor()帮助程序呈现“NewsContent”属性

以下是使其工作的代码:

将您的模型更改为:

用[DataType]属性修饰“NewContent”属性,并将数据类型设置为“MultilineText”。这将指示此属性的编辑器应为多行文本输入

public class News : IStorable
{
    [Required]
    [Display(Name = "Title")]
    public virtual string Title { get; set; }

    [Required()]
    [Display(Name = "Content")]
    [DataType(DataType.MultilineText)]
    public virtual string NewsContent { set; get; }
    //....
}
在视图中,对“News.newcontent”属性使用Html.EditorFor()帮助程序,而不是Html.TextAreaFor()

//....
<div class="editor-label">
    @Html.LabelFor(m => m.News.NewsContent)
</div>

<div class="editor-field" id="container">

    @*@Html.TextAreaFor(m => m.News.NewsContent)*@

    @Html.EditorFor(m => m.News.NewsContent)
    @Html.ValidationMessageFor(m => m.News.NewsContent)
</div>
//....
/。。。。
@LabelFor(m=>m.News.NewsContent)
@*@Html.TextAreaFor(m=>m.News.NewsContent)*@
@EditorFor(m=>m.News.NewsContent)
@Html.ValidationMessageFor(m=>m.News.NewsContent)
//....

是新闻内容丰富的文本区域,如FCKEditor等。现在只是文本区域。我将添加WYSIWYG您使用的实体框架“味道”是什么?它与实体框架有何关系/您能否详细说明哪些不起作用?“标题验证有效,但新闻内容无效”因此这意味着需要
标题
,但您可以提交表单,而无需填写
新闻内容
,或者其他问题?
//....
<div class="editor-label">
    @Html.LabelFor(m => m.News.NewsContent)
</div>

<div class="editor-field" id="container">

    @*@Html.TextAreaFor(m => m.News.NewsContent)*@

    @Html.EditorFor(m => m.News.NewsContent)
    @Html.ValidationMessageFor(m => m.News.NewsContent)
</div>
