Pass list of Entities from View to controller

Question

What I want to do it's simple. I have a view that receives a model that contains 2 lists of 2 entities. I want to pass one of that lists to controller, when I call it. It sounds simple, and I already tried various solution proposed, but can't get this to work. Also I'm new to MVC.

The Model

public class SorteioEspecial
{
    RepositoryService service = new RepositoryService();

    public SorteioEspecial()
    {
        funcionario = new List<Funcionario>();
        ponderacaoFuncionario = new List<PonderacaoFuncionario>();
    }

    public IEnumerable<Funcionario> funcionario { get; set; }
    public IEnumerable<PonderacaoFuncionario> ponderacaoFuncionario { get; set; }

    public IEnumerable<Funcionario> GetFuncionarios()
    {
        funcionario = service.GetFuncionarios();
        return funcionario;
    }

    public IEnumerable<PonderacaoFuncionario> GetPonderacaoFuncionario()
    {
        ponderacaoFuncionario = service.GetPonderacaoFuncionario();
        return ponderacaoFuncionario;
    }


}

The View

    @model Alpd.Models.SorteioEspecial

@using (@Html.BeginForm("EditarPonderacoesEspecialSecond", "Sorteios",Model.ponderacaoFuncionario, FormMethod.Post))
{

  <div class="filterbox">
    <table class="table">
        <tr>
            <th>
                <b>ID</b>
            </th>
            <th>
                <b>ID Funcionário</b>
            </th>
            <th>
                <b>Nome Funcionário</b>
            </th>
            <th>
                <b>Ponderação</b>
            </th>
            <th>
                <b>Incluir Sorteio</b>
            </th>

            <th></th>
        </tr>

        @foreach (var item in Model.ponderacaoFuncionario)
        {
            <tr>
                <td>@Html.DisplayFor(modelItem => item.Id)</td>
                <td>@Html.DisplayFor(modelItem => item.Funcionario)</td>
                <td>@Html.DisplayFor(modelItem => item.Nome_Funcionario)</td>
                <td>@Html.DisplayFor(modelItem => item.Ponderacao)</td>
                <td>@Html.DisplayFor(modelItem => item.Incluir_sorteio)</td>
            </tr>
        }
    </table>

</div>
<!--
<div class="col-md-10">
    <a href='Url.Action("EditarPonderacoesEspecialSecond", "Sorteios", Model.ponderacaoFuncionario)'>
        <input type="submit" value="Editar Ponderações" class="btn-default" />
    </a>
</div>
-->


    @Html.HiddenFor(model => model.ponderacaoFuncionario)
    @Html.EditorFor(model => model.ponderacaoFuncionario)
    <input type="submit" value="Editar Ponderações" class="btn-default" />
}

The controller method

[HttpPost]
    public ActionResult EditarPonderacoesEspecialSecond (SorteioEspecial pf)
    {
        return View(pf);
    }

I just want to call the method, passing the list of entities ponderacaoFuncionario . Dont want to do anything on the view (just show the table). Also if I am not doing this by the proper way, can you give an advice of how to do it?

So you have model SorteioEspecial where do you initialize that class? And what is the exact issue? — Dnyanesh, Feb 25 '15 at 17:31
Are you trying to make an action method in the controller? You are calling the method with a list of `SorteioEspecial` but the view only uses one of those as model, do you want to create a view for each, and what do you want to do with those in that case? — Guffa, Feb 25 '15 at 17:36
@Guffa @ Dnyanesh This view is for show a table (to confirm a submission). On the view I will have a button to confirm, and with a click in this button I want to go to another method and pass it the entire ponderacaoFuncionario list (that will have item from the same entitie), to use in that method! — danielpm, Feb 25 '15 at 17:42

As the view uses a SorteioEspecial you would create an instance of that class to put the list in and use as model:

[HttpPost]
public ActionResult EditarPonderacoesEspecialSecond (List<PonderacaoFuncionario> ponderacaoFuncionario)
{
    SorteioEspecial model = new SorteioEspecial();
    model.ponderacaoFuncionario = ponderacaoFuncionario;
    return View(model);
}

Good point, forget that. But the problem is that pf that the method receive is null. It dont pass from the view to the controller! – danielpm Feb 25 '15 at 18:10
@danielpm: I'm not sure that you can recieve a list as model, you might need to wrap that in a class and use that in the form and as parameter. See: http://stackoverflow.com/questions/15375800/model-binding-to-a-list-mvc-4 – Guffa Feb 25 '15 at 18:29
Guffa, now its not null, but it is 0 (Count=0). If I put a break on foreach in my View, i can see that the list ponderacaoFuncionario is not null. Could be my form that isnt pass the list right? But i cant see why! – danielpm Feb 25 '15 at 18:35
@danielpm: You have the model both as route object in the `BeginForm` and as an `EditorFor`. You should check what each does in the generated page, so you can see which you can use. – Guffa Feb 25 '15 at 18:39
@Guffa: you can, as long as the HTML input names are in the form of `[N].Property`, where `N` is the index. – Chris Pratt Feb 25 '15 at 18:48
@Guffa don't matter wich I use, I get or null or Count = 0. At this point, I would be extremelly happy If I could pass the list of Model.ponderacaoFuncionarios.Id to the controller, but somehow I'm not achieving that also – danielpm Feb 26 '15 at 10:50
@ChrisPratt can you give me an example? – danielpm Feb 26 '15 at 10:51
