如何将两个模型合并为一个模型并使用asp.net MVC剃刀将其传递给视图 [英] How to Combine two models into a single model and pass it to view using asp.net MVC razor

问题描述

我正在尝试将两个模型(tblCategories和tblProducts)组合为一个模型，并将其传递给视图.但是无法.

I'm trying to combine two models (tblCategories and tblProducts) into a single model and pass it to a view. But was not able to.

tblCategory.cs 具有以下数据

namespace ScaffoldCreate.Models
{
    using System;
    using System.Collections.Generic;

    public partial class tblCategory
    {
        public int CategoryId { get; set; }
        public string Name { get; set; }
    }
}

tblProduct.cs

public partial class tblProduct
    {
        public int ProductId { get; set; }
        public int ProductName { get; set; }
        public int CategoryId { get; set; }
        public int SubCategoryId { get; set; }
        public string ProductDescription { get; set; }
        public string StockStatus { get; set; } 
        public IList<tblCategory> CategoryName { get; set; }
    }
}

我尝试将tblCategory放入tblProduct，并尝试按如下方式在索引页中检索它:

I tried to get tblCategory into tblProduct and tried to retrieve that in index page as follows:

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.CategoryName.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CategoryId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.SubCategoryId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductDescription)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.StockStatus)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>
    </tr>
}

但是，我无法通过它.有什么可以帮助我解决这个问题的吗?

But, I was not able to get through it. Could any assist me in solving this ?

推荐答案

为您的视图使用ViewModel，它将解决您的问题:

Use the ViewModel for your View that will Solve your Problem::

class CommonViewModel 
{

   Model1 model1;
   Model2 model2;
}

其中Model1& Model2是您的模型aS ::

where Model1 & Model2 are your Models aS::

public class Model1 
{
  public int ID{get;set;}
  public string Name{get;set;}
}

和Model2一样::

and Model2 like::

public class Model2 
{
  public int ID{get;set;}
  public string Name{get;set;}
}

在您的视图中，您将其作为强类型输入:

And into your View you do it as strongly Typed::

@model ProjectName.CommonViewModel

在这里您可以将Model1用作:: 您也可以将模型传递到另一个局部视图，也可以在同一视图中使用:

Here you can use the Model1 as:: you can pass the Model to Another Partial View As well and can use in the same view as well::

@Html.Partial("_PartialViewName",Model.Model1)

@foreach (var item in Model.Model2)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.CategoryName.Name)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CategoryId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.SubCategoryId)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductDescription)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.StockStatus)
        </td>
        <td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>
    </tr>
}
