I am following along with the music store example to try learn ASP.NET MVC. I'm creating a cookbook application.
I have created my viewmodel that looks like this:
namespace CookMe_MVC.ViewModels
{
public class CookMeIndexViewModel
{
public int NumberOfReceipes { get; set; }
public List<string> ReceipeName { get; set; }
}
}
my controller looks like this
public ActionResult Index()
{
var meals= new List<string> { "Dinner 1", "Dinner 2", "3rd not sure" };
//create the view model
var viewModel = new CookMeIndexViewModel
{
NumberOfReceipes = meals.Count(),
ReceipeName = meals
};
return View(viewModel);
}
Finally my view looks like this
@model IEnumerable<CookMe_MVC.ViewModels.CookMeIndexViewModel>
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table>
<tr>
<th></th>
<th>
Meals
</th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
@Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
</td>
<td>
@item.ReceipeName
</td>
</tr>
}
</table>
I get this error.
The model item passed into the dictionary is of type
CookMeIndexViewModel
, but this dictionary requires a model item of typeIEnumerable<CookMeIndexViewModel>
.
I have followed the example. I can't see what I am doing wrong. Should I be returning my viewmodel as a generic list?
In your view you are using @model IEnumerable<CookMe_MVC.ViewModels.CookMeIndexViewModel>
which indicates that the model expected by the View is of type IEnumerable of CookMeIndexViewModel.
However in the controller you are passing an object of type CookMeIndexViewModel as a model return View(viewModel);
hence the error.
Either change the view to have @model CookMe_MVC.ViewModels.CookMeIndexViewModel
or pass a IEnumerable of CookMeIndexViewModel as model to the view in controller as given below:
public ActionResult Index()
{
var meals= new List<string> { "Dinner 1", "Dinner 2", "3rd not sure" };
//create the view model
var viewModel = new CookMeIndexViewModel
{
NumberOfReceipes = meals.Count(),
ReceipeName = meals
};
List<CookMeIndexViewModel> viewModelList = new List<CookMeIndexViewModel>();
viewModelList.Add(viewModel);
return View(viewModelList);
}
