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)
}
这是一个使用IEnumerable的简化示例。
我在视图上使用了两个模型:一个是带有搜索条件的表单(SearchParams模型)，另一个是用于显示结果的网格，我还纠结于如何在同一个视图上添加IEnumerable模型和另一个模型。这是我想到的，希望能帮助到一些人:
@using DelegatePortal.ViewModels;
@model SearchViewModel
@using (Html.BeginForm("Search", "Delegate", FormMethod.Post))
{
Employee First Name
@Html.EditorFor(model => model.SearchParams.FirstName,
new { htmlAttributes = new { @class = "form-control form-control-sm " } })
<input type="submit" id="getResults" value="SEARCH" class="btn btn-primary btn-lg btn-block" />
}
<br />
@(Html
.Grid(Model.Delegates)
.Build(columns =>
{
columns.Add(model => model.Id).Titled("Id").Css("collapse");
columns.Add(model => model.LastName).Titled("Last Name");
columns.Add(model => model.FirstName).Titled("First Name");
})
.．.
）
SearchViewModel.cs:
namespace DelegatePortal.ViewModels
{
public class SearchViewModel
{
public IEnumerable<DelegatePortal.Models.DelegateView> Delegates { get; set; }
public SearchParamsViewModel SearchParams { get; set; }
....
DelegateController.cs:
// GET: /Delegate/Search
public ActionResult Search(String firstName)
{
SearchViewModel model = new SearchViewModel();
model.Delegates = db.Set<DelegateView>();
return View(model);
}
// POST: /Delegate/Search
[HttpPost]
public ActionResult Search(SearchParamsViewModel searchParams)
{
String firstName = searchParams.FirstName;
SearchViewModel model = new SearchViewModel();
if (firstName != null)
model.Delegates = db.Set<DelegateView>().Where(x => x.FirstName == firstName);
return View(model);
}
SearchParamsViewModel.cs:
namespace DelegatePortal.ViewModels
{
public class SearchParamsViewModel
{
public string FirstName { get; set; }
}
}
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
