Question

I have a room class, which has 3 linked tables, Property, Sex (as in Male/Female), Stage.

I can get the Index controller to return the linked table items, by using Include:

var rooms = db.Rooms.Include(r => r.Property).Include(r => r.Sex).Include(r => r.Stage);

What I don’t know is, how to you include these linked table items in the Details controller:

Room room = db.Rooms.Find(id);

The full controllers are listed below:

    //
    // GET: /Room/

    public ActionResult Index()
    {
        var rooms = db.Rooms.Include(r => r.Property).Include(r => r.Sex).Include(r => r.Stage);
        return View(rooms.ToList());
    }

    //
    // GET: /Room/Details/5

    public ActionResult Details(int id = 0)
    {
        Room room = db.Rooms.Find(id);
        if (room == null)
        {
            return HttpNotFound();
        }
        return View(room);
    }

Thanks for any help,

Mark

After Include statments you could use LINQ’s SingleOrDefault method
Like this:

Room room = db.Rooms.Include(r => r.Property)
        .Include(r => r.Sex)
        .Include(r => r.Stage)
        .SingleOrDefault(r => r.Id = id);
