1,396 PointsTwo repositories for one view
I have a ViewModel that contains all of my Models, both with it's own repository and I'm trying to put them toguether in the same view... this is in Controller
public ActionResult Index()
{
var id = new Receta().Id;
var viewModel = new Modelos()
{
Receta = new Receta(),
Slide = new Slide(),
GetRecetas = new Receta[id]
};
return View(viewModel);
}
this is in ViewModel
public class Modelos
{
public Receta Receta { get; set; }
public Slide Slide { get; set; }
public Receta[] GetRecetas { get; set; }
}
and this is one of the repositories
public class RepositorioRecetas
{
private static Receta[] _recetas = new Receta[]
{
new Receta()
{
Id = 1,
Titulo = "Receta1",
DescripcionHtml = "<p>corta descripcion del producto</p>",
Favorito = false,
RecetaPasos = "bla bla bla"
},
new Receta()
{
Id = 2,
Titulo = "Receta2",
DescripcionHtml = "<p>corta descripcion del producto</p>",
Favorito = false,
RecetaPasos = "bla bla bla"
},
new Receta()
{
Id = 3,
Titulo = "Receta3",
DescripcionHtml = "<p>corta descripcion del producto</p>",
Favorito = false,
RecetaPasos = "bla bla bla"
}
};
public Receta[] GetRecetas()
{
return _recetas;
}
public Receta GetReceta(int id)
{
Receta recetaReturn = null;
foreach (var receta in _recetas)
{
if(receta.Id == id)
{
recetaReturn = receta;
break;
}
}
return recetaReturn;
}
}

1,396 Pointsyes but here I show more code, I have a nullReferenceException but I do set the id so I don't get why I'm not being able to loop through the foreach
@if(Model.Recetas != null)
{
<div class="row">
@foreach (Receta receta in Model.Recetas)
{
<div class="col-md-4">
<div class="well">
<h4>@Html.ActionLink(receta.Titulo, "Receta", new { id = receta.Id, @class = "Recetas" })</h4>
<a href="@Url.Action("Receta", new { id = receta.Id })">
<img src="~/img/fotos/@receta.CoverImageFileName" alt="@receta.MostrarTexto" class="img-responsive" />
</a>
</div>
</div>
}
</div>
}

Try setting a breakpoint at the controller's return and examine the viewmodel at that point.

1,396 Pointshey I figured out how, the code in my controller was wrong and also in the for loop but now everything is working and thanks for the awnser :)
