有一种观点认为MVC多模型 [英] MVC Multiple Models in One View

问题描述

我想在一个视图中到达多个模型。我有DAL文件夹和的DbContext。

I want to reach multiple models in one view. I have DAL folder and DbContext.

class CvContext : DbContext
{
   public CvContext() : base("CvContext")
   {
   }

   public DbSet<LinkModel> Links { get; set; }
   public DbSet<AboutModel> Abouts { get; set; }
   public DbSet<PortfolioModel> Portfolios { get; set; }
   public DbSet<SkillModel> Skills { get; set; }

   protected override void OnModelCreating(DbModelBuilder modelBuilder)
   {
      modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
   }
}

和HomeController的

And HomeController

public class HomeController : Controller
{
   private CvContext db = new CvContext();

   public ActionResult Index()
   {
      return View(db.Links.ToList());
   }
}

Index.cshtml

Index.cshtml

@model IEnumerable<MvcCv.Models.LinkModel>

<ul>
   @foreach (var item in Model)
   {
      <li>
         <a href="@Html.DisplayFor(modelItem => item.LinkUrl)">
                            @Html.DisplayFor(modelItem => item.LinkName)
            <span class="icon"></span>
            <span class="menu-icon">
               <img src="@Url.Content(item.LinkImage)" alt="" />
            </span>
         </a>
      </li>
   }
</ul>

我如何能达到所有型号？我会像链接模型中使用的foreach的项目。谢谢你。

How can i reach all models? I will use foreach for item in Model like Links. Thanks.

推荐答案

您应该创建一个视图模型如下：

You should create a view model as follows:

public class FooViewModel
{
   public IEnumerable<LinkModel> Links { get; set; }
   public IEnumerable<AboutModel> Abouts { get; set; }
   public IEnumerable<PortfolioModel> Portfolios { get; set; }
   public IEnumerable<SkillModel> Skills { get; set; }
}

然后，从控制器填充它们作为你的要求，作为一个例子：

Then from your controller populate them as to your requirements, as an example:

   public ActionResult Index()
   {
      var model = new FooViewModel();
      model.Links = db.Links.ToList();
      model.Abouts = db.Abouts.ToList();
      model.Portfolios = db.Portfolios.ToList();
      model.Skills = db.Skills.ToList();
      return View(model);
   }

然后在您的视图模式更改为 FooViewModel 键，所有的属性将在那里提供。

Then change the model in your view to FooViewModel and all your properties will be available in there.

@model FooViewModel

<ul>
   @foreach (var item in Model.Links)
   {
      <li>
           @item
      </li>
   }
</ul>

<ul>
   @foreach (var item in Model.Links)
   {
      <li>
           @item
      </li>
   }
</ul>

// ....etc, obviously change the outputs as needed.
