视图中的多个模型

我想在一个视图中有2个模型。页面包含LoginViewModel和RegisterViewModel。

e.g.

public class LoginViewModel
{
    public string Email { get; set; }
    public string Password { get; set; }
}

public class RegisterViewModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Password { get; set; }
}

我需要做另一个ViewModel持有这2个ViewModel吗?

public BigViewModel
{
    public LoginViewModel LoginViewModel{get; set;}
    public RegisterViewModel RegisterViewModel {get; set;}
}

我需要将验证属性带到视图中。这就是为什么我需要ViewModels。

有没有其他的方法，比如(没有BigViewModel):

 @model ViewModel.RegisterViewModel
 @using (Html.BeginForm("Login", "Auth", FormMethod.Post))
 {
        @Html.TextBoxFor(model => model.Name)
        @Html.TextBoxFor(model => model.Email)
        @Html.PasswordFor(model => model.Password)
 }

 @model ViewModel.LoginViewModel
 @using (Html.BeginForm("Login", "Auth", FormMethod.Post))
 {
        @Html.TextBoxFor(model => model.Email)
        @Html.PasswordFor(model => model.Password)
 }

当前回答

在你的模型和LoginViewModel和RegisterViewModel属性中创建一个新类: 公共类UserDefinedModel() { 属性a1作为LoginViewModel property a2 as RegisterViewModel ｝然后在视图中使用UserDefinedModel。

将这个ModelCollection.cs添加到您的模型中

using System;
using System.Collections.Generic;

namespace ModelContainer
{
  public class ModelCollection
  {
   private Dictionary<Type, object> models = new Dictionary<Type, object>();

   public void AddModel<T>(T t)
   {
      models.Add(t.GetType(), t);
   }

   public T GetModel<T>()
   {
     return (T)models[typeof(T)];
   }
 }
}

控制器:

public class SampleController : Controller
{
  public ActionResult Index()
  {
    var model1 = new Model1();
    var model2 = new Model2();
    var model3 = new Model3();

    // Do something

    var modelCollection = new ModelCollection();
    modelCollection.AddModel(model1);
    modelCollection.AddModel(model2);
    modelCollection.AddModel(model3);
    return View(modelCollection);
  }
}

视图:

enter code here
@using Models
@model ModelCollection

@{
  ViewBag.Title = "Model1: " + ((Model.GetModel<Model1>()).Name);
}

<h2>Model2: @((Model.GetModel<Model2>()).Number</h2>

@((Model.GetModel<Model3>()).SomeProperty

使用包含多个视图模型的视图模型:

   namespace MyProject.Web.ViewModels
   {
      public class UserViewModel
      {
          public UserDto User { get; set; }
          public ProductDto Product { get; set; }
          public AddressDto Address { get; set; }
      }
   }

你认为:

  @model MyProject.Web.ViewModels.UserViewModel

  @Html.LabelFor(model => model.User.UserName)
  @Html.LabelFor(model => model.Product.ProductName)
  @Html.LabelFor(model => model.Address.StreetName)

你总是可以在ViewBag或View Data中传递第二个对象。

一个简单的方法

我们可以先呼叫所有型号

@using project.Models

然后发送你的模型与viewbag

// for list
ViewBag.Name = db.YourModel.ToList();

// for one
ViewBag.Name = db.YourModel.Find(id);

在视图中

// for list
List<YourModel> Name = (List<YourModel>)ViewBag.Name ;

//for one
YourModel Name = (YourModel)ViewBag.Name ;

然后很容易使用这个模型

有很多方法……

with your BigViewModel you do: @model BigViewModel @using(Html.BeginForm()) { @Html.EditorFor(o => o.LoginViewModel.Email) ... } you can create 2 additional views Login.cshtml @model ViewModel.LoginViewModel @using (Html.BeginForm("Login", "Auth", FormMethod.Post)) { @Html.TextBoxFor(model => model.Email) @Html.PasswordFor(model => model.Password) } and register.cshtml same thing after creation you have to render them in the main view and pass them the viewmodel/viewdata so it could be like this: @{Html.RenderPartial("login", ViewBag.Login);} @{Html.RenderPartial("register", ViewBag.Register);} or @{Html.RenderPartial("login", Model.LoginViewModel)} @{Html.RenderPartial("register", Model.RegisterViewModel)} using ajax parts of your web-site become more independent iframes, but probably this is not the case
