我在发布具有“复杂类型”模型的表单时遇到了一些问题:
我有一个模型:
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; }
}
我的第一个问题是,在发布事件中,我的用户为 null .. 所以我在这里关注了一些帖子(例如MVC- 复杂类型上的模型绑定)使用for而不是foreach,但既然我这样做了,我的表格将不再发布:
看法:
@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" />
}
我的视图通过 ajax 呈现为部分加载(不确定它在这里有什么不同)。知道为什么它不会发布吗?如果我将所有 '[]' 像 'Users[0].FullName' 删除到 Users0.FullName 我会发布,但当然它不会被绑定。
谢谢你的帮助
以备不时之需进行编辑: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) });
}
