我是MVC的新手,对于这个初学者的问题感到抱歉.我有以下模型类:
public class ReturnBookHedModel
{
public int RefferenceID { get; set; }
public int BorrowedRefNo { get; set; }
public int MemberId { get; set; }
public DateTime ReturnDate { get; set; }
public bool IsNeedToPayFine { get; set; }
public DateTime CurrentDate { get; set; }
public virtual List<ReturnBookDetModel> RetunBooks { get; set; }
public virtual MemberModel member { get; set; }
}
public class ReturnBookDetModel
{
public int BookID { get; set; }
public int RefferenceID { get; set; }
public bool IsReturned { get; set; }
public virtual ReturnBookHedModel ReturnBookHed { get; set; }
public virtual BookModel book { get; set; }
}
我有以下控制器方法:
public ActionResult SaveReturnBook(int refNo)
{
ReturnBookHedModel model = ReturnBookFacade.GetReturnBookBasedOnRefference(refNo);
return View(model);
}
//
// POST: /ReturnBook/Create
[HttpPost]
public ActionResult SaveReturnBook(ReturnBookHedModel model)
{
try
{
// TODO: Add insert logic here
return RedirectToAction("Index");
}
catch
{
return View();
}
}
在我的模型中,我定义如下:
<div class="control-label">
@Html.LabelFor(model => model.BorrowedRefNo)
@Html.TextBoxFor(model => model.BorrowedRefNo, new { @class = "form-control" ,@readonly = "readonly" })
@Html.ValidationMessageFor(model => model.BorrowedRefNo)
</div>
// rest of the header details are here
<table>
<tr>
<th>
@Html.DisplayNameFor(model => model.RetunBooks.FirstOrDefault().IsReturned)
</th>
<th>
@Html.DisplayNameFor(model => model.RetunBooks.FirstOrDefault().BookID)
</th>
<th>
@Html.DisplayNameFor(model => model.RetunBooks.FirstOrDefault().book.BookName)
</th>
<th></th>
</tr>
@foreach (var item in Model.RetunBooks)
{
<tr >
<td>
@Html.CheckBoxFor(modelItem => item.IsReturned)
</td>
<td>
@Html.HiddenFor(modelItem => item.BookID);
@Html.DisplayFor(modelItem => item.BookID)
</td>
<td>
@Html.DisplayFor(modelItem => item.book.BookName)
</td>
</tr>
}
</table>
这很好用..但是这些表的详细信息(复杂的对象)不在控制器的post方法中.当我搜索时,发现可以按以下方式使用此详细数据:但我不能按以下方式使用它.
@for (var i = 0; i < Model.RetunBooks.Count; i++)
{
<tr>
<td>
@Html.CheckBoxFor(x => x.RetunBooks.)
</td>
</tr>
}
我如何将这些信息发送到控制器
解决方法:
为了将集合发布回去,您需要按照以下方式对它们进行索引,以使模型活页夹可以将它们拾取.
这应该可以解决问题:
@for (var i = 0; i < Model.RetunBooks.Count; i++)
{
...
@Html.CheckBoxFor(model => Model.RetunBooks[i].IsReturned)
...
}
复杂对象需要以上述方式进行索引.
