一个视图中的MVC多个模型

Question

我想在一个视图中访问多个模型.我有DAL文件夹和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

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

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

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>

我怎样才能到达所有型号？我会在模型链接中使用foreach for item.谢谢.

您应该创建一个视图模型,如下所示:

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; }
}

然后从您的控制器填充它们以满足您的要求,例如:

   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);
   }

然后在视图中更改模型,FooViewModel并在那里提供所有属性.

@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.
