我有一些問題與發佈「複合型」模式的一種形式:模型(複雜類型)不會屈從於行動
我有一個模型:
public class CircleEditViewModel
{
[Key]
public int CircleId { get; set; }
[Required]
[MaxLength(100)]
public string Name { get; set; }
public bool IsSystem { get; set; }
public class UserInCircle
{
public UserInCircle(User user)
{
this.UserId = user.UserId;
FullName = user.FullName;
}
public int UserId { get; set; }
public byte[] Picture { get; set; }
public string FullName { get; set; }
public bool isInCircle { get; set; }
}
public List<UserInCircle> Users { get; set; }
}
我的第一個問題是,在事件後,我的用戶了空..所以我也跟着在這裏的幾個職位(如MVC- Model Binding on a Complex Type)用於代替的foreach一個,但因爲我這樣做,我的表格將不再發布:
查看:
@model Wims.Website.ViewModels.CircleEditViewModel
<script type="text/javascript">
$(document).ready(function() {
$.validator.unobtrusive.parse('form');
});
</script>
@using (Ajax.BeginForm(Html.ViewContext.RouteData.Values["Action"].ToString(), null, new AjaxOptions { HttpMethod = "POST", OnSuccess = "SaveDone(data)" }, new { id = "editform" }))
{
@Html.ValidationSummary(true)
<fieldset>
<legend>Circle</legend>
@Html.Label(DateTime.Now.ToString());
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
</fieldset>
if (Model.Users != null)
{
for (int i = 0; i < Model.Users.Count; i++)
{
<div class="userDetail">
<div>
<div>
@Html.DisplayFor(model => Model.Users[i].isInCircle);
</div>
<div class="iconDiv">
@Html.Image("~/Content/Images/defaultUser.jpg", Model.Users[i].FullName, null);
</div>
<div>
@Html.TextBoxFor(model => Model.Users[i].FullName)
@Html.HiddenFor(model => Model.Users[i].UserId)
</div>
</div>
</div>
<div style="clear: both"></div>
}
}
@Html.GenerateSecureDataControls(model => model.CircleId)
<input type="submit" value="Save" />
}
我的看法是呈現爲部分加載通過ajax(不知道它在這裏有什麼區別)。 任何想法爲什麼它不會發布?如果我刪除所有'[]'用戶[0] .FullName'到Users0.FullName我將發佈,但當然它不會被綁定。
感謝您的幫助
編輯以防萬一需要:操作:
[HttpPost]
public ActionResult Edit(CircleEditViewModel circleData, FormCollection collection)
{
if (ModelState.IsValid)
{
using (var logic = new CircleLogic())
{
Circle circle = logic.GetCircleById(circleData.CircleId, WebMatrix.WebData.WebSecurity.CurrentUserId);
if (circle == null)
{
return HttpNotFound();
}
else
{
circle.Name = circleData.Name;
logic.UpdateCircle(circle, GetSelectedUser(collection));
}
return PartialView("_CircleAndUsers", GetData(logic, circle.CircleId));
}
}
return this.Json(new { success = false, viewdata = RenderRazorViewToString("_CircleAndUsers", circleData) });
}
你能分享生成的表單的HTML嗎? –
您可能想要在UserInCircle上添加默認構造函數。我不認爲模型聯編程序能夠在沒有它的情況下實例化該類型。 –
巴勃羅羅密歐是對的,我添加了一個默認ctor,它的工作。我不認爲我會獨自一人。謝謝! (ps巴勃羅羅密歐隨時可以把它作爲答案,所以我可以標記它解決給你信用:) :)) – Tom
