EntityFramework的下拉列表不显示选项

Question

下午所有，即时通讯新的mvc和实体框架。但是我提到我的模型时有一个问题。

我有一个实体框架模型，看起来像下面的图片：

我已经合并这两个表到一个模型命名Marie_Testing.cs：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.ComponentModel.DataAnnotations; 
using System.ComponentModel.DataAnnotations.Schema; 


namespace EDT_Test.Models.ViewModels 
    { 
    public partial class Marie_Testing 
    { 
    [Display(Name = "Client Ref:")] 
    public int id { get; set; } 

    [Display(Name = "Created By:")] 
    public string CreatedBy { get; set; } 

    public List<Title> allTitles { get; set; } 

    [Required] 
    [Display(Name = "Surname:")] 
    public string Surname { get; set; } 

    [Display(Name = "Additional Surname:")] 
    public string Surname2 { get; set; } 

    [Required] 
    [Display(Name = "Forename:")] 
    public string Forename1 { get; set; } 

    [Display(Name = "Additional Forename:")] 
    public string Forename2 { get; set; } 

我有一个创建。使用该Marie_Testing模型CSHTML页...

@model EDT_Test.Models.ViewModels.Marie_Testing 

@{ 
    ViewBag.Title = "Create"; 
} 

<h2>Create</h2> 

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken() 
    @*@Html.HiddenFor(model => model.allClientData)*@ 

    <div class="form-horizontal"> 
     <h4>Marie_Test</h4> 
     <hr /> 
     @Html.ValidationSummary(true, "", new { @class = "text-danger" }) 
     <div class="form-group"> 
      @Html.LabelFor(model => model.CreatedBy, htmlAttributes: new { @class = "control-label col-md-2" }) 
      <div class="col-md-10"> 
       @Html.EditorFor(model => model.CreatedBy, new { htmlAttributes = new { @class = "form-control", @readonly = "readonly", style = "width:200px;background:E1EBF9;", @Value = "LazzM" } }) 
      </div> 
     </div> 

     <div class="form-group"> 
      @Html.LabelFor(model => model.allTitles, htmlAttributes: new { @class = "control-label col-md-2" }) 
      <div class="col-md-10"> 
       <select id="titleid" name="titlename" class="form-control"> 
        @foreach (var item in Model.allTitles) 
        { 
         <option>@item.id</option> 
        } 
       </select> 
      </div> 
     </div> 

我有一个应该为LI HomeController.cs在创建页面时从数据库的下拉列表中标题。这似乎并不奏效。以下是“创建”操作结果的代码。

//required to get Client data from the Clients: Dbset 
     [HttpGet] 
     public ActionResult Create() 
     { 
      ////set the defaults (dropdown) of the page for the create of of a new record. 
      Marie_Testing vmPopulateData = new Marie_Testing(); 

      List<Title> titles = (from t in db.Titles select t).ToList(); 
      vmPopulateData.allTitles = titles; 

      return View(vmPopulateData); 
     } 

     //required to post ClientML table, vreate a parameter of client 
     [HttpPost] 
     public ActionResult Create(ClientRecord client) 
     { 
      //validate the model and save to employee table. 
      if (ModelState.IsValid) 
      { 
       //this is the db set we are referencing    
       db.ClientRecords.Add(client); 
       db.SaveChanges(); 
       return RedirectToAction("Index"); 
      } 
      return View(client); 
     } 

我可以跑不过当前的代码，并成功地将数据输入到所需的数据库，但是标题字段未填充，因为我可以看到这个调试和步进通过创建代码时。

我不知道为什么标题下拉列表不被填充，因为我可以看到模型在Create.cshtml引用，我可以从剃刀代码中的模型选择这些属性。

我看过一些类似于我的问题的帖子，但我找不到解决问题的方法。

如果有人有任何建议或指点，请你让我知道。
