如何将视图更改映射到数据库MVC 4

我是c# MVC4的ViewModel的新手，有一个问题，我已经思考了好几天，但我找不到解决方案。我想做一个动态表，使用户能够编辑每一行，当用户单击"保存和更新"按钮时，viewModel返回到控制器并将修改保存到数据库。

这是我的viewmodel:

我使用了存储库模式，并且创建了一个服务层:

public class VigiprodView
{
    public IEnumerable<Team> teams { get; set; }
    public IEnumerable<Vigiprod> vigiprods { get; set; }
    public IDictionary<TeamWeek, Vigiprod> vigiprodbyTeamWeek { get; set; }
    public IDictionary<int, Week> weeks { get; set; }
    public Vigiprod getVigrodByTeamAndWeek(Team team, Week week)
    {   var key = new TeamWeek();
        foreach (var k in vigiprodbyTeamWeek.Keys)
        {
            if ((team.teamId == k.teamId) && (week.weekId == k.weekId ))
            {
                key = k;
                break;
            }
        }
        return vigiprodbyTeamWeek[key];
    }
}
    public class TeamWeek
    {
        public int teamId { get; set; }
        public int weekId { get; set; }
    }

在我任职期间，我曾这样写过:

public void saveVigiprodView(VigiprodView vigiprodView)
    {
        foreach (Week week in vigiprodView.weeks.Values)
        {
            this.prodStatusRepository.UpdateWeek(week);
        }
        foreach (Team team in vigiprodView.teams)
        {
            this.prodStatusRepository.updateTeam(team);
        }
        foreach (TeamWeek teamWeek in vigiprodView.vigiprodbyTeamWeek.Keys)
        {
            var teamWeekVigiprod = new TeamWeekVigiprod
            {
                vigiprod = teamWeek.teamId,
                week = teamWeek.weekId,
                team = teamWeek.teamId
            };
            this.prodStatusRepository.updateTeamWeekVigiprod(teamWeekVigiprod);
        }
        this.prodStatusRepository.Save();
    }

在我的控制器中，我定义了一个Edit方法来保存视图模型更改到数据库:

public class ProdStatusController : Controller
{
    [HttpPost]
   public ActionResult EditVigiprod(VigiprodView vigiprod)
   {
        try
        {    
           var service = new ProdstatusService();
           service.saveVigiprodView(vigiprod);
           return RedirectToAction("EditVigiprod");
        }
       catch
        {
            return View("EditVigiprod", vigiprod);
        }
   }
}

嗯，在我看来，我已经成功地正确显示了表格，并且我已经编写了javascript来实现可编辑功能。我想知道的是如何在视图中映射动作"EditVigiprod"到控制器?以下是我的观点:

 @Model ProdStatus.Models.VigiprodView

@using (Html。BeginForm("Edit"， "ProdStatus"， Model, FormMethod.Post))

<input type="submit" name="Save" id="save" value="Save and update" />
<br>
<table id="itable" class="editableTable">
    <thead>
        <tr>
            <th>
                <div class="out"><b>Weeks</b> <em>Teams</em> </div>
            </th>
            @for (int key = 1; key <= 15; key++)
           {
                <th>
                    @Model.weeks[key].weekNumber
                </th>
           }
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model.teams)
     {
            <tr class="stats-row">
                <td>
                    @item.teamName
                </td>
                @for (int key = 1; key <= 15; key++)
       {
                    <td class="vigiprod">
                        @Model.getVigrodByTeamAndWeek(@item, @Model.weeks[key]).label
                    </td>
       }
            </tr>
     }
    </tbody>
</table>

在我看来，我试图使用BeginForm与控制器"绑定"动作，但是当我单击按钮时，数据库中没有任何更改，页面显示我找不到视图EditVigiprod。我想知道如何从视图返回视图模型到控制器。

非常感谢!
