我有一个模型, ApplicantBranchList
,被用作一个更大的模型的属性如下:
[Display(Name = "Where would you want to work?")]
public ApplicantBranchList PreferedBranches { get; set; }
ApplicantBranchList
:
public class ApplicantBranchList : ViewModel
{
public ApplicantBranchItem HeaderItem { get; set; }
public ApplicantBranchList()
{
HeaderItem = new ApplicantBranchItem();
}
public void MapFromEntityList(IEnumerable<ApplicantBranch> applicantBranches)
{
var service = new BranchService(DbContext);
var selectedIds = applicantBranches.Select(b => b.BranchId);
Items = service.ReadBranches()
.Where(i => !i.IsDeleted)
.Select(p => new ApplicantBranchItem { BranchName = p.Name, WillWorkAt = selectedIds.Contains(p.Id) });
}
public IEnumerable<ApplicantBranchItem> Items { get; set; }
}
ApplicantBranchList
有自己的编辑模板,并在每个项目内编辑模板ApplicantBranchList
:
查看/共享/ EditorTemplates / ApplicantBranchList.cshtml:
@model Comair.RI.UI.Models.ApplicantBranchList
<table>
<tr>
<th style="display: none;"></th>
<th>
@Html.DisplayNameFor(model => model.HeaderItem.BranchName)
</th>
<th>
@Html.DisplayNameFor(model => model.HeaderItem.WillWorkAt)
</th>
</tr>
@foreach (var item in Model.Items)
{
@Html.EditorFor(m => item)
}
</table>
查看/共享/ EditorTemplates / ApplicantBranchItem.cshtml:
@model Comair.RI.UI.Models.ApplicantBranchItem
<tr>
<td style="display: none;">
@Html.HiddenFor(m => m.BranchId)
</td>
<td>
@Html.DisplayFor(m => m.BranchName)
</td>
<td>
@Html.EditorFor(m => m.WillWorkAt)
</td>
</tr>
这个编辑器中正确呈现在视图中,但在后的行动:
public ActionResult Create(ApplicantProfileModel model)
{
if (ModelState.IsValid)
{
var branches = model.PreferedBranches;
PreferedBranches.Items
是null
。
我究竟做错了什么?
