我正在尝试在强类型剃刀视图中编辑项目列表.模板不允许我在单个视图中编辑对象列表,因此我将List视图与Edit视图合并.我只需要在复选框中编辑一个布尔字段.
问题是我无法将数据恢复到控制器.我该怎么做？的FormCollection？可视数据？提前致谢.
问题是我无法将数据恢复到控制器.我该怎么做？的FormCollection？可视数据？提前致谢.
这是代码：
楷模：
public class Permissao
{
public int ID { get; set; }
public TipoPermissao TipoP { get; set; }
public bool HasPermissao { get; set; }
public string UtilizadorID { get; set; }
}
public class TipoPermissao
{
public int ID { get; set; }
public string Nome { get; set; }
public string Descricao { get; set; }
public int IndID { get; set; }
}
控制器动作：
public ActionResult EditPermissoes(string id)
{
return View(db.Permissoes.Include("TipoP").Where(p => p.UtilizadorID == id));
}
[HttpPost]
public ActionResult EditPermissoes(FormCollection collection)
{
//TODO: Get data from view
return RedirectToAction("GerirUtilizadores");
}
视图：
@model IEnumerable<MIQ.Models.Permissao>
@{
ViewBag.Title = "EditPermissoes";
}
@using (Html.BeginForm())
{
<table>
<tr>
<th></th>
<th>
Indicador
</th>
<th>
Nome
</th>
<th>Descrição</th>
<th></th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.CheckBoxFor(modelItem => item.HasPermissao)
</td>
<td>
@Html.DisplayFor(modelItem => item.TipoP.IndID)
</td>
<td>
@Html.DisplayFor(modelItem => item.TipoP.Nome)
</td>
<td>
@Html.DisplayFor(modelItem => item.TipoP.Descricao)
</td>
</tr>
}
</table>
<p>
<input type="submit" value="Guardar" />
</p>
}
解决方法
How do i do it? FormCollection? Viewdata?
以上都不是,使用视图模型：
[HttpPost]
public ActionResult EditPermissoes(IEnumerable<Permissao> model)
{
// loop through the model and for each item .HasPermissao will contain what you need
}
在视图内部而不是编写一些循环使用编辑器模板：
<table>
<tr>
<th></th>
<th>
Indicador
</th>
<th>
Nome
</th>
<th>Descrição</th>
<th></th>
</tr>
@Html.EditorForModel()
</table>
并在相应的编辑器模板内(〜/ Views / Shared / EditorTemplates / Permissao.cshtml)：
@model Permissao
<tr>
<td>
@Html.CheckBoxFor(x => x.HasPermissao)
</td>
<td>
@Html.DisplayFor(x => x.TipoP.IndID)
</td>
<td>
@Html.DisplayFor(x => x.TipoP.Nome)
</td>
<td>
@Html.DisplayFor(x => x.TipoP.Descricao)
</td>
</tr>
