Question

I have generated a strongly-type view from a model class that I have created from scratch. I have used the List as the scaffold template. The error appears at the foreach line with the model object.

View:

@model IEnumerable<HockeyPoolStats.Models.Player>

@{
    ViewBag.Title = "Index";
}

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.Team_Id)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Rank)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.PlayerName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.PlayerTeam)
        </td>
[...]

Controller:

 public class PlayerController : Controller
    {

        private HockeyPoolStatsDB _db = new HockeyPoolStatsDB();

        //
        // GET: /Player/


    public ActionResult Index()
    {
        Player _player = new Player();
        _db.Players.Add(_player);
        var model = _db.Players;

        return View(model);
    }

    }

DbContext

public class HockeyPoolStatsDB : DbContext
    {

        public DbSet<Player> Players { get; set; }
        public DbSet<Team> Teams { get; set; }
        public DbSet<Goalie> Goalies { get; set; }


    }

I don’t understand why model is null. This means that the controller isn’t passing the model to the view correctly?

Answer 1

It more likely means that _db.Players is returning null.

Set a breakpoint and step through it and verify that _db.Players is actually returning a list of players.
