Definition not found for C# MVC model property

I have this model:

public class RamalModel
{
    public int ID { get; set; }
    public string  Nome { get; set; }
    public int Numero { get; set; }
}

And I create a partial view:

@model RamalAguia.Models.RamalModel

<div>

    <h4>@Model.Nome</h4>

    <span>@Model.Numero</span>
    <hr />

</div>

In my controller I'm using it:

public class HomeController : Controller
{
    RamaDb _db = new RamaDb();

    public ActionResult Index()
    {
        var model = _db.Ramais.ToList();

        return View(model.ToList());
    }
}

But when I try to put:

@Html.RenderPartial("_Ramal", Model.Nome , new ViewDataDictionary());

It doesn't work and shows this error:

Error 1 'System.Collections.Generic.List' does not contain a definition for 'Nome' and no extension method 'Nome' accepting a first argument of type 'System.Collections.Generic.List' could be found (are you missing a using directive or an assembly reference?) c:\dev\Teste\RamalAguia\RamalAguia\Views\Home\Index.cshtml 9 37 RamalAguia

Someone can help me? Thanks

SOLVED

In my partial view:

@model List<RamalAguia.Models.RamalModel>   

@{
    foreach(var item in Model) {
        <h4>@item.Nome</h4>       
        <span>@item.Numero</span>
        <hr />
    }
}

And in my Index:

@model List<RamalAguia.Models.RamalModel>


        @Html.Partial("_Ramal", Model);

Thanks for help.

Your model is List<RamaModel> and you in

@Html.RenderPartial("_Ramal", Model.Nome , new ViewDataDictionary());

trying to get from variable type RamaModel not from list.

For render first elemet you can use:

@Html.RenderPartial("_Ramal", Model[0].Nome , new ViewDataDictionary());

Or for show all ramas in list:

@foreach (var item in Model)
{
    @Html.RenderPartial("_Ramal", item.Nome , new ViewDataDictionary());
}

EDIT

In View

Change

@model RamalAguia.Models.RamalModel

to

@model List<RamalAguia.Models.RamalModel>

And in controller

return View(model.ToList());

.ToList() is unnecessary.

I'm not sure what you want to accomplish but I'm assuming you want to display a list of RamalModel on a page. In your controller:

public ActionResult Index()
    {
        var model = _db.Ramais.ToList();   
        return View(model);
    }

And when rendering your partial:

@model List<RamalAguia.Models.RamalModel>
...
@Html.RenderPartial("_Ramal", Model, new ViewDataDictionary());

and inside your partial, to loop through the list:

@model List<RamalAguia.Models.RamalModel>    

foreach(var item in Model) {
   <h4>@item.Nome</h4>       
   <span>@item.Numero</span>
   <hr />
}

Another approach:

You can loop through the list and render a partial view for each one, depends on what you want to achieve: 

@model List<RamalAguia.Models.RamalModel>    

    foreach(var item in Model) {
       @Html.RenderPartial("_Ramal", item, new ViewDataDictionary());
    }
