asp.net - 如何在索引和编辑 View (强绑定(bind))中传递和合并 MVC3 中的两个模型？

Question

模型/数据库实体关系(基线占位符文学内容):

public class TitlePercent
{
   public int TitleName; 
   public decimal Percentage;      
}

public class TitleMonthly
{
   public string Month;
   public int Val;
}

基数 => 1 TitlePercent 到 * TitleMonthly

图解 View (建议):

_____________________________
Name  | % ||  Jan | Feb |
_____________________________
Title1 2%     23    343
Title2 3%     343   3434
_____________________________

Controller (建议):

    // Need view and edit   
    public ViewResult ViewTitlePercentAndTitleMontly()
    {
        return View(db.<NotSureWhatWouldGoHere>.ToList());
    }

    public ActionResult EditTitlePercentAndTitleMontly(int id)
    {
        return View(db.<NotSureWhatWouldGoHere>.Find(id));
    }

Razor View(建议的伪):
...查看和编辑
@model MVC3.Models.TitlePercent
@model2 MVC3.Models.TitleMonthly

1. For Index View to show the grid not sure how to mash this up (like the grid)
   - Perhaps build this in the controller but not sure how to build and pass that to the view as
     I have had not dealt with multiple models as relationships.
2. For Edit View need to figure out how to bind to a model similar to:
    @Html.EditorFor(model => model.TitleName)
    @Html.EditorFor(model => model.Percentage)

    foreach TitleMonthly in TitlePercentag
    {
       @* Iterate and bind somehow *@
       @Html.EditorFor(model2 => model2.Month)
       @Html.EditorFor(model2 => model2.Val)
    }
    ???

抱歉缺少细节和伪代码，但我只是不必处理多个模型，特别是如果它们彼此相关/依赖，并且可以通过连接的类/表创建 GridView ......那么如果你想编辑一行(两个类的组合，那么如何基于这两个类模型将所有关系绑定(bind)到文本框)？

再次，我将对此进行 mock ，但任何信息和示例将不胜感激。

通常你使用一个叫做 ViewModel 的东西。这是一个为 View 设计的非常具体的模型。您将使用数据模型中的信息填充该模型，然后将其传递给 View 。它不必具有 1:1 的结构，这可以让您拥有更多或更少的信息，具体取决于您的需要。

对于您的编辑器模型，您可以创建类似于以下内容的 ViewModel:

public class TitleEditingViewModel { 
    public TitlePercent TitlePercent {get;set;}
    public ICollection<TitleMonthly> MonthlyTitles {get;set;}
}

然后，您可以根据需要在 Controller 中填充该模型，然后将模型传递到 View 中。

@Html.EditorFor(model => model.TitlePercent.TitleName)
@Html.EditorFor(model => model.TitlePercent.Percentage)

@foreach titleMonthly in Model.MonthlyTitles {
   @Html.EditorFor(model => titleMonthly.Month)
   @Html.EditorFor(model => titleMonthly.Val)
}
