沒有局部視圖載荷從父視圖

Question

我有一個父視圖和局部視圖，但是當它試圖從父視圖加載局部視圖收到以下錯誤

模型項目通過了到字典是類型'System.Data.Objects.DataClasses.EntityCollection`1 [RolMVC3.Models.OFFICE]'，但是這個字典需要一個'RolMVC3.Models.OFFICE'類型的模型項目。

局部視圖：

@model RolMVC3.Models.OFFICE 
     @Html.HiddenFor(model => model.IdOffice) 
     @Html.HiddenFor(model => model.IdSCampus) 
     <div class="editor-label"> 
      @Html.LabelFor(model => model.AddressOffice) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.AddressOffice) 
      @Html.ValidationMessageFor(model => model.AddressOffice) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.PhoneOffice) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model..PhoneOffice) 
      @Html.ValidationMessageFor(model => model..PhoneOffice) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.EmailOffice) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.EmailOffice) 
      @Html.ValidationMessageFor(model => EmailOffice) 
     </div> 

父視圖：

@model RolMVC3.Models.CAMPUS_UNIVERSITY 

@{ 
    ViewBag.Title = "Edit"; 
} 

<h2>Edit</h2> 

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> 
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> 

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

    <h2> @ViewBag.University.Name - @ViewBag.Campus.NameCity </h2> 

    <fieldset> 
     <legend>MODIFY OFFICE</legend> 

     @Html.HiddenFor(model => model.IdUniversidty) 

     @Html.HiddenFor(model => model.IdCityCampus) 

     @Html.HiddenFor(model => model.IdCampus) 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.AddressCampus) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.AddressCampus) 
      @Html.ValidationMessageFor(model => model.AddressCampus) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.PhoneCampusSede) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.PhoneCampus) 
      @Html.ValidationMessageFor(model => model.PhoneCampus) 
     </div> 

     <div class="editor-label"> 
      @Html.LabelFor(model => model.EamailCampus) 
     </div> 
     <div class="editor-field"> 
      @Html.EditorFor(model => model.EamailCampus) 
      @Html.ValidationMessageFor(model => model.EamailCampus) 
     </div> 

     <fieldset> 
     <legend>DATA</legend> 
     @Html.Partial("_Office", Model.OFFICE) 
     </fieldset> 
      <p> 
      <input type="submit" value="Save" /> 
     </p> 
    </fieldset> 
} 

控制器：

public ActionResult Edit() 
     { 
      decimal id; 
      id = (decimal)Session["Offi"]; 

      ViewBag.University = (from c in db.OFFICE 
            join s in db.CAMPUS_UNIVERSITY on c.IdCampus equals s.IdCampus 
            join u in db.UNIVERSIDTY on s.IdUniversity equals u.IdUniversity 
            where c.IdOffice == id 
            select u).Single(); 

      ViewBag.Campus = (from c in db.OFFICE 
          join s in db.CAMPUS_UNIVERSITY on c.IdCampus equals s.IdCampus 
          join ci in db.CIUDAD on s.IdCaityCampus equals ci.IdCity 
          where c.IdOffice == id 
          select ci).Single(); 

      OFFICE office = db.OFFICE.Single(c => c.IdOffice == id); 

      CAMPUS_UNIVERSITY campus_university = db.CAMPUS_UNIVERSITY.Single(s => s.IdSede == office.IdCampus); 


      return View(campus_university); 
     } 

祝福

Answer 1

你的控制器具有代碼

OFFICE office = db.OFFICE.Single(c => c.IdOffice == id); 
CAMPUS_UNIVERSITY campus_university = db.CAMPUS_UNIVERSITY 
             .Single(s => s.IdSede == office.IdCampus); 

但你的觀點是隻能使用模型CAMPUS_UNIVERSITY。我會假設CAMPUS_UNIVERSITY.Office屬性是EntityCollection<OFFICE>，它不符合Office的視圖要求。

一種解決方案是顯示所有辦事處：

@foreach(var office in Model.OFFICE) 
{ 
    @Html.Partial("_Office", office) 
} 

或另一種是實際使用Office你在控制器中創建

控制器（ADD）

ViewBag.Office = db.OFFICE.Single(c => c.IdOffice == id);   

查看（更改）

@Html.Partial("_Office", ViewBag.Office)

能告訴你什麼是RolMVC3.Models.OFFICE和CAMPUS_UNIVERSI TY對象看起來像？我猜你的CAMPUS_UNIVERSITY模型有一些奇怪的現象。 .OFFICE字段是作爲OFFICE對象緊密轉換還是可枚舉？您可以通過在視圖中傳入Model.OFFICE [0]來快速測試。

Answer 3

看起來您正在傳遞與期望值不同的類型。從您的角度來看，我可以預見到該視圖預計會出現「OFFICE」類型的對象。您確定您傳遞給部分視圖調用的模式是相同類型嗎？還是你通過了一個辦公室名單？
