帮助MVC POST请求 [英] Help for MVC POST request

问题描述

大家好。这是我与MVC的第一个项目。我有一个与MVC有关的问题，希望对我有所帮助。我的英语非常糟糕，我道歉。我想更新一个对象但没有得到想要的结果。



这是我当前的viewModel

Hello to all.This is my first project with MVC.I have a question relating to MVC and will hopefully help me. My English is very bad for that I apologize.I want to update an object but not getting the desired result.

This is my current viewModel

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

namespace SmartHomeMVC.ViewModel
{
    public class DevicesViewModel
    {
        public List<Device> DevicesForCurrentUser { get; set; }
        public Room CurrentRoom { get; set; }
    }
}

这是我的观点

This is my view

<h2>CreateSettings</h2>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)

    <fieldset>
        <legend>DevicesViewModel</legend>
        <h3>Current temp @Model.CurrentRoom.CurrentTemp</h3>
         <div class="editor-field">
         <h3> Target temp   @Html.EditorFor(model =>model.CurrentRoom.TargetTemp)</h3>
             <h3> Termostat    @Html.EditorFor(model =>model.CurrentRoom.Termostat) </h3>
        </div>
        
        <table>
             <tr >
        <th>
            
            @Html.DisplayNameFor(model => model.DevicesForCurrentUser.FirstOrDefault().Name)
        </th>
        <th>
             @Html.DisplayNameFor(model => model.DevicesForCurrentUser.FirstOrDefault().State)
        </th>
       
     
        <th></th>
    </tr>
              </table>
@foreach (var item in Model.DevicesForCurrentUser)
{
   
        @item.Name
   
      <div class="editor-field">
          
           @Html.EditorFor(model => item.State)
        </div>
            
}

但我没有结果

but I get no results

[HttpPost]
   public ActionResult Edit(DevicesViewModel collection)
   {

       try
       {
           // TODO: Add update logic here

collection - > DevicesForCurrentUser = null

collection -> DevicesForCurrentUser = null

推荐答案

我认为你需要指定你的帖子方法名称，以便在使用MVC时将数据传递给服务器。

请检查。

I think you need to specify your post method name to pass your data to server while using MVC.
