Question

I want to have ASP.NET MVC website that would have some frontend for looking into, adding and other things with data. And then I want to have Web Api for getting data for mobile devices and so. I want to use code first from EF (and I am using Ninject). I create classes for hotel and others. I created HotelManagerContext and database is created and looks good. I am adding data by HomeController and by Repository for this. When I looked at database in Visual Studio data are there. But when I tried to use my HotelsController for Api datacontext is empty. What’s wrong? What I forget to set? Something with connection string or what?

This is my ApiController:

public class HotelsController : ApiController
{
    private IHotelRepository _hotelRepo { get; set; }

    public HotelsController(IHotelRepository repo)
    {
        _hotelRepo = repo;
    }

    // GET api/Hotels
    public IEnumerable<Hotel> GetHotels()
    {
        return _hotelRepo.GetAll();
    }

    // GET api/Hotels/5
    public Hotel Gethotel(int id)
    {
        return _hotelRepo.Get(id);
    }
}

This is part of my controller for frontend:

public class HomeController : Controller
{
    private IHotelRepository _hotelRepo { get; set; }

    public HomeController(IHotelRepository repo)
    {
        _hotelRepo = repo;
    }


    public ActionResult Index()
    {
        return View();
    }

    // next methods, for adding data and so
}

This is my repository:

public class HotelRepository : IHotelRepository
{
    private HotelManagerContext db { get; set; }

    public HotelRepository()
        :this (new HotelManagerContext())
    {
    }

    public HotelRepository(HotelManagerContext hotelManagerContext)
    {
        // TODO: Complete member initialization
        this.db = hotelManagerContext;
    }

    public Models.Hotel Get(int id)
    {
        return db.hotels.SingleOrDefault(h => h.hotId == id);
    }

    public IQueryable<Models.Hotel> GetAll()
    {
        return db.hotels;
    }


    public Hotel Add(Hotel hotel)
    {
        db.hotels.Add(hotel);
        db.SaveChanges();
        return hotel;
    }
}

This is my HotelManagerContext:

public class HotelManagerContext : DbContext
{
    public HotelManagerContext() : base("name=HotelManagerContext")
    {
    }

    public DbSet<Hotel> hotels { get; set; }
}

Edit:

    private static void RegisterServices(IKernel kernel)
    {
        kernel.Bind<IHotelRepository>().To<HotelRepository>();
        GlobalConfiguration.Configuration.DependencyResolver = new NinjectResolver(kernel);
    }    

Edit2:
Here is my connection string:

<add name="HotelManagerContext" connectionString="Data Source=(localdb)\v11.0; Initial Catalog=HotelManagerContext-20121219191411; Integrated Security=True; MultipleActiveResultSets=True; AttachDbFilename=|DataDirectory|HotelManagerContext-20121219191411.mdf" providerName="System.Data.SqlClient" />

And I just found that even in HomeController I have empty datacontext. So when I check content of database in Server Explorer there are data which I added (in HomeController). But everytime when I have request page (web api or frontend) datacontext is empty and I can add items there are counting from zero but in database there are already next but can’t get it. It’s really weird.

I can’t find solution for this so I create new project and I did everything like in the question. I have same classes, copy and paste code frome question. I can’t find any important difference but second time it’s working.

I know this isn’t exactly solution but in this case I could start my project from begging so I tried it and it really helps. Just don’t know where is problem.
