부분 뷰 수 = 0, 컨트롤러에 값이 전송되지 않음

Question

부분 뷰 형식의 값만 컨트롤러로 전달되지 않습니다./FounderInvestmentVM은 부분 뷰를 생성 한 것이며이 VM은 다른 값은 컨트롤러로 전달되지만 부분 뷰의 값은 전달되지 않습니다. 이 FounderInvestorVM을 포함하는 내 재산 VM이/

이다 : 그것은 항상 내가 디버거를 넣어 볼 FounderInvestments Count=0 제공 -

namespace propertyMgmt.ViewModel.PropertyViewModel 
{ 
    public class PropertyViewModel 
    {  
     public int? Id { get; set; } 
     [Required] 
     [DisplayName("Property Title")] 
     public string PropertyTitle { get; set; } 
     ...... 
     public List<FounderInvestmentViewModel> FounderInvestments { get; set; }=new List<>(FounderInvestmentViewModel); 
    } 
} 

이것은 FounderInvestorVM입니다 : -

public class FounderInvestmentViewModel 
    { 
     public int? Id { get; set; } 
     public int PropertyId { get; set; } 
     public int InvestorId { get; set; } 
     public double Investment { get; set; } 
     public int InstallmentPeriod { get; set; } 
     public IEnumerable<SelectListItem> FounderInvestorList { get; set; } 
    } 

이 내 컨트롤러 -

public ActionResult Create(PropertyViewModel _propertyViewModel) 
    { 
    if (ModelState.IsValid) 
     { 
     Property property = new Property(); 
     property.Id = _propertyViewModel.Id ?? 0; 
     property.PropertyTitle = _propertyViewModel.PropertyTitle; 
     ........other properties......   
     } 
     _propertyQueryProcessor.Create(property); 
     foreach(var investment in _propertyViewModel.FounderInvestments) 
      { 
       FounderInvestment _founderInvestment = new FounderInvestment 
       { 
        Id = investment.Id??0, 
        InstallmentPeriod = investment.InstallmentPeriod, 
        InvestorId = investment.InvestorId, 
        PropertyId = investment.PropertyId, 
        Investment = investment.Investment 
       }; 
       _founderInvestmentQueryProcessor.Create(_founderInvestment);  
    } 

일부보기 : -

@model propertyMgmt.ViewModel.FounderInvestmentViewModel 
@{ 
    ViewData.TemplateInfo.HtmlFieldPrefix = "PropertyViewModel"; //bind to main model 
} 

<div class="founderInvestmentDetails"> 
    @using (Html.BeginCollectionItem("founderInvestmentDetails")) 
    { 
     @Html.HiddenFor(m => m.Id, new { @class = "id" }) 

     @Html.HiddenFor(m=>m.PropertyId, new { @name = "PropertyId" }) 

     <div class="form-group"> 
      @Html.LabelFor(m => m.FounderInvestorList, htmlAttributes: new { @class = "control-label col-md-2" }) 
      <div class="col-md-10"> 
       @Html.DropDownListFor(m=>m.FounderInvestorList,Model.FounderInvestorList , "Select Investor", htmlAttributes: new {@class = "form-control"}) 
       @Html.ValidationMessageFor(m => m.FounderInvestorList, "", new { @class = "text-danger" }) 
       @Html.HiddenFor(m => m.InvestorId, new { @name = "InvestorId" }) 
      </div> 
     </div> 

     <div class="form-group"> 
      @Html.LabelFor(m => m.Investment, htmlAttributes: new { @class = "control-label col-md-2" }) 
      <div class="col-md-10"> 
       @Html.EditorFor(m=>m.Investment, new { htmlAttributes = new { @class = "form-control",@type="number" } }) 
       @Html.ValidationMessageFor(m => m.Investment, "", new { @class = "text-danger" })    
      </div> 
     </div> 
     <div class="form-group"> 
      @Html.LabelFor(m => m.InstallmentPeriod, htmlAttributes: new { @class = "control-label col-md-2", @type = "number" }) 
      <div class="col-md-10"> 
       @Html.EditorFor(m => m.InstallmentPeriod, new { htmlAttributes = new { @class = "form-control" } }) 
       @Html.ValidationMessageFor(m => m.InstallmentPeriod, "", new { @class = "text-danger" })     
      </div> 
     </div> 
    } 
</div> 

그리고 마지막으로이 주요 VIEW는 다음과 같습니다 -

은

@model propertyMgmt.ViewModel.PropertyViewModel.PropertyViewModel 
    @using (Html.BeginForm("Create", "Property", FormMethod.Post, new { enctype = "multipart/form-data" })) 
    { 
    <div class="form-group"> 
     @Html.LabelFor(model => model.PropertyTitle, htmlAttributes: new { @class = "control-label col-md-2" }) 
     <div class="col-md-10"> 
      @Html.EditorFor(model => model.PropertyTitle, new { htmlAttributes = new { @class = "form-control" } }) 
      @Html.ValidationMessageFor(model => model.PropertyTitle, "", new { @class = "text-danger" }) 
     </div> 
    </div> 
    .....(other form groups) 
    <div id="founderInvestmentDetails" class="form-group"> 
     @foreach(var founderInvestmentDetails in Model.FounderInvestments) 
     { 
     @Html.Partial("_FounderInvestmentDetails", founderInvestmentDetails) 
     } 
    </div>

죄송합니다, here.As @Stephen Muecke이

을 지적 바보 같은 실수가 있었다

@using (Html.BeginCollectionItem("founderInvestmentDetails")) 

은이어야한다

@using (Html.BeginCollectionItem("FounderInvestments")) 

BeginCollectionItem은의 이름을 사용하기 때문에에서 작업 중입니다.
