Asp.net mvc 3 MVC3数据val-*属性未从模型编辑器模板发出

我已经为我当前的MVC3项目中的一个模型创建了一个编辑器模板。此模型正在为基础模式的属性调用正确的编辑器，但它们缺少用于验证的不引人注目的数据val-*属性

如何让MVC发出数据val属性

这是我的模型

[MetadataType(typeof(FieldTripRouteMetadata))]
public partial class FieldTripRoute
{
    private class FieldTripRouteMetadata
    {
        [Required]
        [DisplayFormat(DataFormatString = "{0:d}")]
        public DateTime Date { get; set; }

        [Required]
        [DisplayName("Route")]
        public int RouteID { get; set; }

        [Required]            
        [DisplayName("Departure Time")]
        [UIHint("TimeWithPeriod")]
        [DisplayFormat(DataFormatString = "{0:h:mm tt}")]
        public DateTime DepartureTime { get; set; }

        [Required]
        [StringLength(255)]
        [DisplayName("Pickup Location")] 
        public String PickupLocation { get; set; }

        [Required]
        [StringLength(255)]
        public String Destination { get; set; }

        [Required]            
        [DisplayName("Arrival Time")]
        [UIHint("TimeWithPeriod")]
        [DisplayFormat(DataFormatString = "{0:h:mm t}")]
        public DateTime ArrivalTime { get; set; }

        public bool IsReturnRoute { get; set; }

        public int FieldTripID { get; set; }
    }

和我的编辑器模板：

@model FieldTripRoute

@{string routeType = (Model.IsReturnRoute ? "return" : "");}

<fieldset class="add@(routeType)Route" style="clear: both; width: 620px; margin-right: auto; margin-left: auto;">
    <legend>Add Route</legend>
    <div style="float: left; width: 275px;">
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.Date)</div>
            <div class="editor-field">@Html.EditorFor(model => model.Date)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.Date)</div>
        </div>
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.DepartureTime)</div>
            <div class="editor-field">@Html.EditorFor(model => model.DepartureTime)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.DepartureTime)</div>
        </div>
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.ArrivalTime)</div>
            <div class="editor-field">@Html.EditorFor(model => model.ArrivalTime)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.ArrivalTime)</div>
        </div>
    </div>
    <div style="float: left;">
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.RouteID)</div>
            <div class="editor-field">@Html.DropDownListFor(model => model.RouteID, Model.EditRouteList)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.RouteID)</div>
        </div>
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.PickupLocation)</div>
            <div class="editor-field">@Html.TextBoxFor(model => model.PickupLocation)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.PickupLocation)</div>
        </div>
        <div>
            <div class="editor-label">@Html.LabelFor(model => model.Destination)</div>
            <div class="editor-field">@Html.EditorFor(model => model.Destination)</div>
            <div class="validation-error">@Html.ValidationMessageFor(model => model.Destination)</div>
        </div>          
    </div>        
    <div style="clear: both; width: 100px; margin: 20px auto 0 auto;">
        <input type="button" id="submit@(routeType)Form" name="submit@(routeType)Form" value="Add" />
    </div>
</fieldset>

我查看了所有的基本编辑器模板，它们都符合将名称保留为空字符串以允许MVC生成它的想法。但是我仍然没有验证。

我能够通过在编辑器模板前后添加一个表单标记并添加

this.ViewContext.FormContext=new-FormContext（）使其正常工作；

在编辑器模板的开头

当控件被传递到编辑器模板时，它似乎会丢失当前表单上下文。我尝试只添加ViewContext.FormContext命令，但如果不添加表单标记，嵌入模型将无法验证

所以现在我有一个表单在表单中，它按预期工作，但似乎应该有一个更简单的方法

formContext命令的想法来源于

您是否检查了web配置？是的，这已经在网站的web.config中启用了。我能够解决这个问题。如果允许的话，我将发布一个完整的解释。如果您使用Html.BeginForm（）。在内部，它将为您创建FormContext，而不是您手动声明它。问题是，在多个表单之间有多个表单是无效的html，因此我无法在嵌套的viewmodels周围放置表单，并且仍然有有效的html。

public class FieldTripEditViewModel
{
    public FieldTrip Trip { get; set; }        
    public FieldTripRoute Route { get; set; }        
    public FieldTripRoute ReturnRoute { get; set; }

    public FieldTripEditViewModel(){}

    public FieldTripEditViewModel(FieldTrip trip)
    {
        this.Trip = trip;
        this.Route = new FieldTripRoute();
        this.ReturnRoute = new FieldTripRoute {IsReturnRoute = true};
    }
}
