如何使用一个控制器使用多个模型 [英] How to work with multiple model with one controller

问题描述

我是MVC的新手，我正在MVC创建我的第一个现场项目，我想知道如何使用多个模型和一个控制器。



我有三个或更多的模型类然后我将创建另一个包装类，其中包含多个模型类的对象，之后我将创建一个控制器，我想要所有这些操作，如添加，编辑，详细信息，删除所有一个控制器中的那些类。那么，谁能告诉我这个怎么用呢。

推荐答案

1.定义一个将收集多个模型对象列表的类

2.在控制器中访问该对象类列表并发送给您的视图对象此模型列表of class

Ex。

First Model Class

1.Define a class which will collect more than one models list of object
2.In a controller access that list of object class and send to your view object this model list of class
Ex.
First Model Class

namespace MvcApplication1.Models
{
    public class Class1
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}

第二模型类

Second Model Class

namespace MvcApplication1.Models
{
    public class Class2
    {
        public int Id { get; set; }
        public string Category { get; set; }
    }
}

集合类和DbContext

Collection class and DbContext

using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;

namespace MvcApplication1.Models
{
    public class ClassCollection
    {
        public int Id { get; set; }
        public List<class1> FirstClassList { get; set; }
        public List<class2> SecondClassList { get; set; }
    }
    public class DbClass : DbContext
    {
        public DbSet<classcollection> ClassCollections { get; set; }
    }
}
</classcollection></class2></class1>

在控制器中定义

Define in Controller

using MvcApplication1.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication1.Controllers
{
    public class myController : Controller
    {

        DbClass db = new DbClass();
        public ActionResult Index()
        {
            var list = db.ClassCollections.ToList();
            return View();
        }

    }
}

强类型视图

模型类：ClassCollection（MvcApplication1.Models）

和你的脚手架模板：把它们中的任何一个像细节一样

查看页面

strongly-typed view
Model class: ClassCollection (MvcApplication1.Models)
And Your Scaffold template : take any of them like "Details"
View page

@model MvcApplication1.Models.ClassCollection
@using MvcApplication1.Models 
@{
    ViewBag.Title = "Index";
}

Index
 ClassCollection 
<div>
    First model class value
   @foreach (Class1 item in @Model.FirstClassList)
   {
       <span>  Id:@item.Id</span>
       <span>Name:@item.Name</span>
   }   
</div>
<div>
     Second model class value
   @foreach (Class2 item in @Model.SecondClassList)
   {
       <span>  Id:@item.Id</span>
       <span>Name:@item.Category</span>
   }   
</div>

非常简短：

为您定义一个界面通常适合的控制器。然后为不同的需求实现这个接口并支持工厂实例化。



我或多或少确定SA会做出更好的解决方案。



问候

In very very short:
Define an interface for your controller which fits generally. Afterwards implement this interface for the different requirements and support a factory to instantiate.

I’m more or less sure SA will respond much better solution.
