Asp.net ModelView方法

我想用asp.net MVC4（razor語法）和databasefirst方法構建一個單頁的應用程序。您可以看到我的應用程序的簡單模擬如下。Asp.net ModelView方法

-OPPORTUNITY<br /> 
--OPPORTUNITY DETAIL(1)<br /> 
---Seleted Solution-1<br /> 
---Seleted Solution-2<br /> 
---Seleted Solution-3<br /> 
--OPPORTUNITY DETAIL(2)<br /> 
---Seleted Solution-1<br /> 
---Seleted Solution-2<br /> 
--OPPORTUNITY DETAIL(3)<br /> 
---Seleted Solution-1<br /> 
---Seleted Solution-2<br /> 
---Seleted Solution-3<br />

我在表中有很多解決方案，並且有很多參數。什麼是在一頁中顯示所有信息的最佳途徑。我正嘗試使用創建一個新的viewmodel。但是我不確定它的性能，因爲它從表中獲取所有數據。

這裏是我的模型類..

我開始創建一個MODELVIEW首先顯示一個機會和相關的細節，但我失敗了？

這裏是我的模型視圖類：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using CRM_V1.Models; 

namespace CRM_V1.ViewModels 
{ 
    public class OppViewModel 
    { 

     public List<CRM_OPPORTUNITIES> OppList { get; set; } 
     public List<CRM_OPP_DETAILS> OppDetailList { get; set; } 


    } 
}

我的控制器動作

public ActionResult addingDetailNew(decimal id = 0) 
     { 
      CRM_OPPORTUNITIES crm_opportunities = db.CRM_OPPORTUNITIES.Find(id); 


      var viewModel2 = new OppViewModel 
      { 
       viewModel2 = db.CRM_OPPORTUNITIES.ToList() 

      }; 



      if (crm_opportunities == null) 
      { 
       return HttpNotFound(); 
      } 
      return View(viewModel2); 
     }

最後我的看法。

@model CRM_V1.ViewModels.OppViewModel 

@{ 
    ViewBag.Title = "addingDetailNew"; 
} 

<h2>addingDetailNew</h2> 

@Html.DisplayFor(model => model.NOTES)

但我無法得到NOTES字段。而我的第二個問題是如何獲得像model.CUSTOMERS.NAME這樣的加入字段。？

您必須對您的視圖模型的OppList財產循環，你需要更新你的觀點：

@model CRM_V1.ViewModels.OppViewModel 

@{ 
    ViewBag.Title = "addingDetailNew"; 
} 

<h2>addingDetailNew</h2> 

@foreach(CRM_OPPORTUNITIES opportunity in model.OppList) { 
    <h3>@opportunity.NOTES</h3> 
    @foreach(CRM_OPP_DETAILS detail in opportunity.CRM_OPP_DETAILS){ 
     <p>@detail.CODE</p> 
     <!-- etc... if you want to retrieve more informations --> 
    } 
}

之後是可以繼續檢索對象你想/性能。

希望它的幫助！

我應該如何重新編寫模型視圖和控制器類來檢索所選的OPP和DETAIL信息。我試圖獲得選定的OPP，但我無法檢索DETAILS。 – umki

您可以返回一個唯一的OPP，然後在DETAILS上循環。 –

感謝您的幫助。但我有一個問題。我在我的viewmodel中只有一個CRM_OPP，並將其作爲OppList傳遞給視圖（實際上它不僅僅是一個對象的列表）。我如何獲得與foreach相關的CRM_OPP_DETAILS？代碼中的opportunity.CRM_OPP_DETAILS的輸出是什麼？是因爲EF獲得相關的詳細信息嗎？ – umki
